FDA approves first U.S. treatment for Chagas disease

The US Food and Drug Administration (FDA) announced yesterday that it has granted accelerated approval for the nation’s first treatment for Chagas disease, a parasitic infection caused by Trypanosoma cruzi spread by kissing bugs that has increasingly been found in the United States, especially in Texas’s Rio Grande Valley area.

The drug benznidazole, made by Chemo Research, SL, of Madrid, is approved for use in children ages 2 to 12 years old who have Chagas disease. Its safety and efficacy were shown in two placebo-controlled clinical trials in children 6 to 12 years old. An additional study in kids ages 2 to 12 helped set dosing recommendations. Stomach pain, rash, decreased weight, and headache were among the most common adverse reactions, and the drug was associated with some serious risks, including skin reactions, nervous system effects, and bone marrow depression.  Continue reading

New discovery may improve future mosquito control

by Steve Byrnes, Texas A&M AgriLife

Major rainfall across most of Texas triggering hordes of mosquitos coupled with seemingly constant mosquito-related Zika virus media reports from around the globe may have set the stage perfectly for what one researcher deems as a very significant discovery in man’s war against earth’s leading human disease carrier.

Dr. David Ragsdale, head of the entomology department at Texas A&M University, College Station, credits Dr. Patricia Pietrantonio, a Texas A&M AgriLife Research Fellow in the entomology department at College Station, along with her students and colleagues from other institutions, with discovering a receptor on the legs of mosquitoes that when activated, keeps female mosquitoes from taking a sugar meal and makes them fly away.

New Orleans pests beware: city’s mosquito, rodent and termite control board fights to make city’s buildings pest free

I’ve written several stories about how IPM changes the environment of a school or building when pests are no longer harassing the people inside the building. I’ve also passed along recommendations from specialists on how people can make buildings uninviting for pests. So when I went to New Orleans in April to help present a Friends of Southern IPM Implementer Award to the New Orleans Mosquito, Rodent and Termite Control Board, I wanted to see for myself how their work in IPM has changed the city.
