A study conducted in São Paulo, Southern Hemisphere's biggest city, shows that mosquitoes belonging to vector species make up for seven out of the eight most common species found in municipal parks; adapted to urban environment, they benefit from the fragmentation of green areas, a process which leads to the extinction of wild species.
To detect detect intestinal schistosome infections, the World Health Organization recommends using the Kato-Katz technique, which analyzes slides of fecal matter. But the approach often misses people who are infected with only a low burden of parasites and, as a consequence, shed only a few eggs in fecal samples. Researchers have now analyzed the efficacy of other testing approaches in a setting with low parasite burden; their results appear in PLOS Neglected Tropical Diseases.
Attack at the protein front: Xanthomonas bacteria cause diseases in tomato and pepper plants and inject harmful proteins into plant cells. Researchers from Martin Luther University Halle-Wittenberg (MLU), the University of Bonn, the University of Freiburg and the Leibniz Institute of Plant Biochemistry (IPB) in Halle have now discovered how one of these proteins manipulates the nutrient supply and hormonal balance of plants. Their study was recently published in the renowned journal "Nature Communications".
Some tropical birds have longer egg incubation times than their temperate cousins, even though their habitat is teeming with egg-eating predators. The reason why has long been a mystery, but a new study from The Auk: Ornithological Advances applies new methods to confirm the evidence for an old hypothesis -- that a longer development period leads to a stronger, more efficient immune system.
Researchers have discovered crucial new processes that allow malaria parasites to escape red blood cells and infect other cells, offering potential new treatment targets. The team are already working with pharmaceutical companies to use this knowledge to develop new antimalarial drugs - a critical step in the battle against drug-resistant malaria.
The frequency of adverse reactions to benznidazole is high when treating chronic Chagas patients, although they were mostly mild effects, according to a study led by ISGlobal, in collaboration with the Hospital Clinic of Barcelona. The results point to the need of finding drug combinations or dosages in order to maintain efficacy but decrease its toxicity.
In patients with Chagas Disease, the odds of being infected by the intestinal worm Strongyloides stercoralis increases by two-fold, according to a study led by the Barcelona Institute for Global Health (ISGlobal). The study, published in Plos Neglected Tropical Diseases, underlines the potential benefits of performing a combined screening for both infections among Latin American adults living in Europe.
The majority of Californian Anna's Hummingbirds appear to have P. huitzilopochtlii feather mites on their tail flight feathers, according to a study published Feb. 14, 2018, in the open-access journal PLOS ONE by Youki Yamasaki from Washington State University, US, and colleagues.
A 26-year-old Oregon woman was the first known case of a human being infected with the cattle eyeworm Thelazia gulosa, which normally affects large animals. She was likely infected while being around cows near her rural home, experts conclude in a paper published in the American Journal of Tropical Medicine and Hygiene.
North Americans may be more vulnerable than previously thought to irritating and potentially dangerous infections with two different types of tiny but tenacious eye worms, according to two studies published today in the American Journal of Tropical Medicine and Hygiene.
