Study sheds light on parasite that causes river blindness
(Washington University School of Medicine) The parasite that causes river blindness infects about 37 million people in parts of Africa and Latin America, causing blindness and other major eye and skin diseases in about 5 million of them. A study from Washington University School of Medicine in St. Louis sheds light on the genetic makeup of the parasite, a step toward the goal of eradication.
ConclusionThe culture system we have established forO.volvulus young adult worms offers a promising new platform to advance drug discovery against the human filarial parasite,O.volvulus and thus supports the continuous pursuit for effective macrofilaricidal drugs. However, thisin vitro culturing system will have to be further validated for reproducibility before it can be rolled out as a drug screen for decision making in macrofilaricide drug development programs.
Onchocerciasis, or river blindness, is a dermal filariasis caused by infection with the nematode parasite Onchocerca volvulus, transmitted to humans through the bites of blackflies of the genus Simulium. Despite ...
The new data could help identify treatments for diseases ranging from river blindness to schistosomiasis.
ConclusionKeen observation on the part of physicians is mandatory during the administration of ivermectin for quick recognition and prevention of this adverse drug reaction.
(Scripps Research Institute) Scientists at Scripps Research have developed a urine diagnostic to detect the parasitic worms that cause river blindness, also called onchocerciasis, a tropical disease that afflicts 18 to 120 million people worldwide.
Conclusions/SignificanceWe report for the first time the anti-onchocercal activities of these locally consumed medicinal plants and lantadene A, a potential lead for further development as an onchocerciasis cure.
Conclusions/SignificanceWHO criteria have been met, therefore MDA in Bioko Island can be stopped. Three years of post-treatment surveillance should be implemented to identify any new occurrences of exposure or infection.
