Kizzy was Pit Bulls and Parolees rescue – diagnosed with deadly Chagas disease.

February 2, 2016 | by Nesa Nourmohammadi | Animal Planet

Kizzy was the first dog at Villalobos to be diagnosed with Chagas disease.
Saturday’s heartbreaking episode of Pit Bulls and Parolees showed us the devastating effects of Chagas disease. What originated in Latin America through the “kissing bug” has found its way into parts of the United States and the Villalobos Rescue Center dogs in Assumption Parish felt it first hand. While Kizzy wasn’t so lucky, Leo was fortunate enough to find a treatment that improved his quality of life, thanks to Dr. Kristen Kulinksi and her staff at Cypress Lake Animal Hospital.

We were lucky enough to get some time with Dr. Kristen to learn more about Chagas disease. Take a look at our Q&A with her.

Q: What is Chagas’ disease?

A: Chagas’ disease, also known as American Trypanosomiasis, is a parasitic disease caused by infection with the protozoa, Trypanosoma cruzi. This protozoal parasite lives inside the Triatoma (reduviid) bug, also know as the “kissing bug” or the “assassin bug”. The infective form of the parasite is passed in the feces of the bug. Not all kissing bugs are infected with the protozoa parasite. In Texas, it has been reported that about 50% of the kissing bugs carry the disease.

Q: How is Chagas’ disease transmitted in dogs?

A: T. Cruzi, is passed in the feces of the kissing bug, and is not transmitted through their blood sucking bite. The infected feces can enter the body through open wounds, scratches, or even the initial bite of the kissing bug. Dogs can also be infected by eating the bug, or food contaminated with the kissing bug’s infected feces. Chagas’ can also be transmitted by blood transfusions, through the placenta from an infected mother to the feti, or by handling tissue that is contaminated with the disease.

Q:  Is the Kissing Bug the only vector for the disease?

A:  Yes, there are many different Triatoma species throughout the Americas, although they are all considered “kissing bugs”. Different species may have different behaviors that make infection more or less likely. Some of the bugs in South America defecate as soon as they feed, which places the infected feces directly near the open bite wound.

Q:  Where is it common? in what countries?

A:  Chagas’ disease has been found in North, Central, and South America where the reduviid bugs live. T. Cruzi can not exist without the kissing bug as the vector. It is considered endemic in South America and Mexico in humans. Recently we have been seeing a increase in canine cases in some of the southern United States as the disease travels north through Mexico (Texas, Louisiana, and California are among the states with confirmed cases).

Q:  Who can get Chagas’ disease?

A:  Many mammals can be infected by T. Cruzi, including, but not limited to; humans, rats, dogs, raccoons, skunks.  Opossums and armadillos have also been reported to carry the disease. Wildlife can serve as an important reservoir for the disease.

Q:  Why is Chagas’ disease a problem in dogs?

A:  The initial infection with Trypanosoma Cruzi, can cause vague or even no clinical signs.  Fever, enlarged lymph nodes, and anorexia (lack of appetite) are a few of the vague symptoms seen in the acute phase.  There is also a latent phase that may last for years, where the protozoa is present in the body, but does not cause any signs of disease. The chronic infection of Chagas’ disease can cause heart disease by damaging the heart muscle and ultimately causing a heart arrhythmia and heart failure. Sudden death due to a heart arrhythmia is sometimes the only sign of the disease. To make it even more confusing, some dogs that are infected will never develop signs of the disease.

Q:  Who is at risk?

A:   Dogs that live outside and in wooded areas in sections of the country that have the kissing bug are most at risk.  People and animals who travel to areas that are endemic for the disease also are at higher risk.

Q:  Do you see Chagas’ disease often in your clinic? Is it common or rare?

A: Now that we are looking and testing more for Chagas’, we see around 2 to 3  positive cases a month.  Before I graduated from vet school, 10 years ago, I was taught that I may diagnose 1 case in my professional lifetime.  So although Chagas’ is not as common as heartworm disease in our practice (which we diagnose daily), it is definitely something I test and look for in certain cases.

Q: Is there a treatment for Chagas’?

A: There is no published proven “cure” for Chagas’ disease. There are some anti-protozoal treatments that have been used in humans, but are difficult to acquire and have had limited success in dogs. Treatment has been aimed at treating the symptoms of the disease, such as the heart failure.  Fortunately through research, there have been some experimental treatments which are promising.  I have had three canine cases so far that have proven this treatment to be successful.  This research will soon be published and available by the researcher that has discovered it.

Q: How does I know if my dog has Chagas’?

A: Testing for Chagas’ disease in dogs can be done by having your veterinarian submit a blood sample to a specialized lab for further analysis. PCR (VRL lab) and IFA Antibody tests (Texas A&M Veterinary Diagnostic Lab) are both available only through your veterinarian.

Q:  How do I prevent the disease?

A:  There is no medicine or vaccine that can prevent the disease. Prevention is more aimed at decreasing the exposure of animals and humans to the kissing bug that harbors the disease.  These bugs live in wooded areas, and are attracted to light at night.  Keeping dogs inside at night and away from wooded areas, where the bug may be hiding, can help limit exposure to the disease.  Certain insecticides can be used to treat areas that may serve as a habitat for the kissing bug.

Q: What about humans?

A:  Transmission of Trypanosoma cruzi from dog to human has NOT been reported. Although the presence of the disease in dogs, could show that the disease is present in that region, and may indicate that humans may also be exposed.

Q:  Anything else about the disease?

A:  I don’t want everyone all throughout the country to worry that their dog has Chagas’ disease. Right now the disease is emerging into the United States, but it is still a rare disease in most parts of the country.  I do see a lot of stray and rescue animals at my practice, and these dogs are more likely to have been exposed to the kissing bug through their prior living conditions.  These animals are at higher risk, which is why I have more positive cases in my hospital.

My personal goal is to have veterinarians in certain areas of the country to now have Chagas’ disease as a possible differential diagnosis for certain patients. Earlier detection of the disease will also help improve the outcome for the patient because once the heart has been damaged, the effects are permanent.  Hopefully this experimental treatment protocol will continue to be successful and this disease will not always equal a death sentence every time it is diagnosed.

My desire to help patients with this disease comes from the loss of two young dogs that were owned and loved by my personal friends. Through the frustration of losing these pets, I have learned more about this emerging disease, and now have successfully treated new patients.

Q: Is there anything you’d like to acknowledge?

A: I would also like to thank Dr. Roy Madigan of The Animal Hospital of Smithson Valley in Spring Branch, Texas for his help and for sharing his knowledge of this disease.

Here’s how California could be missing pesticides’ cancer risk – #sayNOtoPESTICIDES!

The local community is concerned about high levels of pesticides used near Rio Mesa High School in Oxnard, Calif., which is surrounded by strawberry fields on all four sides.

California’s pesticide police could be missing a serious health concern for residents and farmworkers by failing to monitor what happens when pesticides get mixed together.

As a new report from UCLA highlighted today, California studies only how each individual pesticide affects human health. Often, however, workers and residents are exposed to a number of pesticides at the same time.

That can happen when pesticides get mixed together before they’re applied to fields or when different pesticides are used in the same field on the same day. A growing body of science is showing that the chemical cocktails could create greater health risks than each pesticide does on its own.

In particular, the report shows how three fumigants – a type of gaseous pesticide central to the strawberry industry and used near schools and homes – might combine to increase the risk of cancer for bystanders. Essentially, once in the human body together, the chemicals can team up to attack and mutate DNA in a way they wouldn’t on their own.

“The regulatory system that is supposed to protect people from harmful levels of pesticide exposure has been slow to deal with interactive effects when setting exposure limits for pesticides,” the report says.

The California Department of Pesticide Regulation’s mission is to protect humans and the environment from the dangers of pesticides. The report’s authors, who come from UCLA’s law and public health schools, said the department must begin studying the combined effects. And they point out that low-income and minority residents are at the greatest risk.

“DPR is required to assess this risk and protect public health, but isn’t doing so,” the authors wrote.

The department already is under fire for how it has managed fumigants, which can spread easily through the air. A Reveal investigation found that department leaders allowed growers and Dow AgroSciences to use heavy amounts of one fumigant despite strenuous objections of scientists because of its potential to cause cancer.

When Ventura County residents subsequently raised concern about the pesticide’s use in strawberry fields near Rio Mesa High School, department Director Brian Leahy responded with a series of exaggerations and contradictions.

The department has curtailed the pesticide’s use and begun drafting rules that would limit pesticide use around schools and require residents to be notified of fumigant use near their homes. However, the state continues to keep open the loophole it created at Dow’s request.

Last week, the department’s second-in-charge, Chris Reardon, left without explanation after nearly 13 years with the agency. An appointee of the governor, Reardon maintained close ties with the agricultural industry, copies of his calendars show.

The UCLA report focused on the fields around Rio Mesa High School to make its case. The school is boxed in on all four sides by conventional strawberry fields. Although pesticides aren’t applied during school hours, the gases can linger in the air for weeks after they’re applied without teachers or students knowing.

Combined, the health risk could be much greater than those of the individual pesticides.

“In fact, modeling shows that over the course of about one week people who live and work in the area around Rio Mesa High School in Ventura County were exposed to large doses of multiple fumigants,” the report says. “This level of exposure raises concerns about possible interactive effects.”

The report points out that 35 percent of all fumigants were applied on the same field on the same day as another fumigant, and 26 percent were applied as part of a pesticide mix.

The authors recommend the following changes in California’s pesticide regulation:

  • Pesticides sold as part of a mixture should be tested before being approved for use.
  • When pesticides are mixed at the field or applied near each other, regulators should require testing or create strict restrictions if there’s a reasonable chance of human harm.
  • The combined effects of the pesticides should be considered in the initial health research done by the Department of Pesticide Regulation and the rules it creates around the pesticides’ use.

BedBugs reported in some of NYC’s swankiest hotels. They were always there; and it’s getting worse. More important to follow as BedBugs transmit deadly Chagas disease.

February 8, 2016 | by Leonard Greene | New York Daily News
It’s not just the fleabags and flophouses.

Bedbugs have been reported in some of the city’s swankiest hotels with a list that includes the Waldorf Astoria the Millennium Hilton and the New York Marriott Marquis.

According to the Bedbug Registry, a nationwide database of bedbug reports and complaints, bedbug sightings in New York hotels have jumped more than 44 percent between 2014 and 2015.

The data focused on establishments that are members of the Hotel Association of New York City.

Of the 272 association members, 65 percent, or 176 members, have had a guest file at least one complaint about bedbugs at the property.

Eighteen hotels had a combined 363 complaints, representing 42 percent of all bedbug complaints.

“I stayed in room 2306 for one night,” a Millennium Hilton guest wrote in a complaint to the hotel in 2014. “I found blood on my sheets and a live bug on my bed. I ended up with 60 plus bites.”

At the Times Square Doubletree guest said a stay there last year left hundreds of bite marks on the face, neck arms and hands.

“Extreme case of bed bug attacked on my entire upper body,” the guest wrote.” Went home to Florida a day early and ended up in my local emergency room.”

Last month, a California couple posted a YouTube video about their $400-a-night Central Park hotel room nightmare. The couple found dozens of bedbugs beneath their mattress at the Astor on the Park Hotel.

Lisa Linden, a spokeswoman for the hotel association, said hotels in New York are addressing the issue.

“Bedbugs are a global issue that extend beyond hotels,” Linden said.

”Every member of the Hotel Association of NYC that we are aware of has an active anti-bedbug program in place. If a problem arises, it is dealt with immediately and effectively.”

Scientists who recently studied the bloodsucking creatures in the city’s subway system discovered a genetic diversity among bedbugs depending upon the neighborhood where they were found.

They said the discovery could lead to better insecticides.

Messing with BedBugs’ Genes Could Carry Other Risks?

Bed Bugs Will Outlive All Of Us Unless We Screw With Their Genes

Bed bugs, like cockroaches and new seasons of The Bachelor, seem impossible to eradicate from the face of the Earth, no matter how many exterminators our landlords call to spray that one time and then never, ever again. But Science says there’s some small hope for the extinction of a moviegoer’s biggest fear—screwing with their genome.

Scientists have managed to map the genome of the common bed bug, revealing some fun things about the little suckers. For instance, bed bugs are actually able to break down toxins, like the ones an exterminator might use, to render them harmless, allowing them to survive even when you try to whack them with bug killer. They’ve also been MUTATING, producing genes that make them resistant to certain insecticides and making it all the more difficult to eradicate an infestation. Another fun fact is that bugs’ genes vary from location to location—a Brooklyn bed bug will have a different genetic sequence from a Queens bed bug, though both are equally disgusting.

Bed bugs also inbreed, and their sex is quite violent. This violent sex has been well-documented, and for those of you who have not yet seen Isabella Rossellini’s bed bug porno, you’re welcome, and sorry:

The takeaway here is that bed bugs have been able to hold us hostage for a long time, but scientists might be able to murder them, provided they make a few genetic tweaks. First, though, let’s kill all the mosquitoes.

Genome of BedBug shows close relationships to Kissing Bug, one of several vectors for deadly Chagas disease, and the body louse. Both have tight associations with humans.

February 2, 2016 | News from Weill Cornell Medical College

Researchers Sequence First Bedbug Genome.  Scientists have assembled the first complete genome of one of humanity’s oldest and least-loved companions: the bedbug. The new work, led by researchers at the American Museum of Natural History and Weill Cornell Medicine, and published Feb. 2 in Nature Communications, could help combat pesticide resistance in the unwelcome parasite. The data also provides a rich genetic resource for mapping bedbug activity in human hosts and in cities, including subways.

“Bedbugs are one of New York City’s most iconic living fossils, along with cockroaches, meaning that their outward appearance has hardly changed throughout their long lineage,” said one of the paper’s corresponding authors Dr. George Amato, director of the museum’s Sackler Institute for Comparative Genomics. “But despite their static look, we know that they continue to evolve, mostly in ways that make it harder for humans to dissociate with them. This work gives us the genetic basis to explore the bedbug’s basic biology and its adaptation to dense human environments.”

The common bedbug (Cimex lectularius) has been coupled with humans for thousands of years. This species is found in temperate regions and prefers to feed on human blood. In recent decades, the prevalence of heated homes and global air travel has accelerated infestations in urban areas, where bedbugs have constant access to blood meals and opportunities to migrate to new hosts. A resurgence in bedbug infestations since the late 1990s is largely associated with the evolution of the insects’ resistance to known pesticides, many of which are not suitable for indoor application.

“Bedbugs all but vanished from human lives in the 1940s because of the widespread use of DDT, but unfortunately, overuse contributed to resistance issues quite soon after that in bedbugs and other insect pests,” said Louis Sorkin, an author on the paper and a senior scientific assistant in the Museum’s Division of Invertebrate Zoology. “Today, a very high percentage of bedbugs have genetic mutations that make them resistant to the insecticides that were commonly used to battle these urban pests. This makes the control of bedbugs extremely labor intensive.”

The researchers extracted DNA and RNA from preserved and living collections, including samples from a population that was first collected in 1973 and has been maintained by museum staff members since then. RNA was sampled from males and females representing each of the bug’s six life stages, before and after blood meals, in order to paint a full picture of the bedbug genome.

When compared with 20 other arthropod genomes, the genome of the common bedbug shows close relationships to the kissing bug (Rhodnius prolixus), one of several vectors for Chagas disease, and the body louse (Pediculus humanus), which both have tight associations with humans.

Trending today: #Bedbugs are developing a strong resistance to most common insecticides

February 2, 2016 | by Ryan Biek | Newsy

Bedbugs are reportedly building up a strong resistance to some of the most powerful insecticides due to overuse, which means we might need to turn to non-chemical solutions to get rid of them.

Researchers from Virginia Tech and New Mexico State University tested the most common class of insecticide called neonicotinoids, or neonics, which is often combined with pyrethroids in commercial treatments for bedbugs.

Bedbugs are developing a strong resistance to most common insecticides photo

They took a group of bedbugs that came from homes in Ohio and Michigan, which had previously been exposed to neonics, and compared those bedbugs to a population that has been kept in isolation for 30 years, before the insecticide was used.

A third group of bedbugs that was resistant to pyrethroids but never exposed to neonics was also included in the study.

Depending on the specific types of neonic tested, the Ohio and Michigan bedbugs were hundreds to tens of thousands of times more resistant than the isolated group.

The third group’s results were in the middle: more resistant than the isolated group but less resistant than the Ohio and Michigan bedbugs.

Because that third group had never been exposed to neonics, the researchers believe the bedbugs may have a pre-existing resistance mechanism.

The researchers said more non-chemical methods need to be used to combat bedbug infestations. However, they noted the most resistant bedbugs in the study only came from two areas, and not all of the U.S. may be facing this level of resistance.

Deadly Chagas Disease-Spreading ‘Kissing Bug/Love Bug’ In U.S. Both Bugs are cousins to the Bed Bug.

“Kissing bugs” are now carrying Chagas in the U.S.

By Madison Burke | November 5, 2014

If you’re one of the people freaked out by Ebola, here’s another thing to potentially freak out about. “Kissing bugs” may be spreading a rare disease in the U.S.

Trypanosoma cruzi, or “kissing bugs” as they’re better known, crawl on people’s faces at night and suck their blood.

And there’s more. The bugs are spreading a disease called Chagas, which can lead to heart problems and intestinal complications.

The Centers for Disease Control and Prevention  says Chagas occurs primarily in rural areas of Latin America and in recent years has been showing its face in the U.S.

While much of the outbreak in Latin America has to do with the kissing bugs, the CDC believes most U.S. cases occur from a patient visiting an affected country or from mother-to-baby, blood transfusions and organ transplants.

However, researchers from Baylor College of Medicine in Houston found 36 percent of the 17 Texas blood donors who tested positive for Chagas appeared to have contracted it from the kissing bugs. The team also found several bugs in the area carrying the disease, although no direct correlation has been made.

Chagas researcher Nolan Garcia said, “Physicians should consider Chagas when patients have swelling and enlargement of the heart not caused by high blood pressure, diabetes or other causes, even if they do not have a history of travel.”

The World Health Organization says Chagas presents in two phases. In the acute phase, a large amount of parasites circulate in the blood. Some people show no symptoms at all, while others may have fever, headache and chest pains along with other symptoms.

In the chronic phase, the parasites are mainly in the heart and digestive muscle. Around 30% of patients suffer from a heart disorder and 10% suffer from a digestive disorder.

When discovered early, Chagas can be treated [but not cured] with medication. As with most illnesses, doctors say the earlier you catch it the better.

Denver – Don’t let the bed bugs bite!

January 15, 2016 | by Nancy Melear | FOX 31

If you wake up in the middle of the night with the horrifying feeling of your skin (literally) crawling, you might want to break out the magnifying glass:  it was just announced that Denver is #11 on Terminix’s most bed bug-infested city list.  What’s even scarier though, is the fact that bed bugs aren’t just waiting for you in your bed: they’re in the dresser where you keep your clothes, the bag you take to work, the bus you ride downtown and the conference room of your first meeting.

It’s a complete myth that bed bugs only thrive in mattresses!

Bed bug issues in the East prompts some to stop reselling furniture

December 15, 2015 | by Josh Birch

GREENVILLE, N.C. (WNCT) – A bed bug problem that some exterminators said is growing in areas in the East has prompted some to ban selling furniture and mattresses for the time being.The Pitt County Online Yardsale posted a message to users on December 12th informing people they no longer could sell or buy couches or furniture. This message came just one day after WNCT’s original story reported a possible bed bug problem in some Greenville Housing Authority’s units.

Tom Davis with D and D Pest Control said the bed bug problem is spreading.

“Usually you’re seeing them in the low income areas, now it’s starting to spread out and getting into the university area and then some of the higher income people,” Davis said.

Getting rid of bed bugs once you have them is an expensive process, one that could end up costing you thousands of dollars. Davis said they generally either use a heat or chemical treatment.

Places that resell furniture like the Salvation Army are by law required to sanitize mattresses before selling them. Robert Frye with the Salvation Army in Greenville said they won’t take mattresses that appear to have bed bugs. As soon as mattresses arrive, they are taken to the sanitization room where they are exposed to high temperatures for several hours.

While state law requires this process to be followed for reselling mattresses, it doesn’t apply to other items bed bugs can travel on like couches and clothes. For those, Frye said it is just an eye test.

“We inspect them again, to make sure they’re in good condition,” he said. “We look at the surroundings where they come out of, and we do the best we can.”

Bargain prices for items are generally what drive people into stores like the Salvation Army. Bonita Tyson was there looking at a bed for sale.

“In the store it normally costs about $500 or $600, and they have it here for like $199,” she said.

However, she said she is always careful about what she brings in to her home. She said whenever she buys something, she always sanitizes it herself before it enters her house.

If you move into a unit or house and find there are bed bugs there, you have up until 60 days to notify your landlord. At that time, the landlord would be responsible for treating the bed bugs. If more than 60 days go by, state law says the tenant is then responsible.
