today’s birthday: Sir Ronald Ross (1857)


Sir Ronald Ross (1857)

Born and raised in India, English physician Ronald Ross joined the Indian Medical Service after completing medical school and undertook the study of malaria, then a disease that was not well understood. After years of research, he demonstrated the malarial parasite, Plasmodium, in the stomach of the Anopheles mosquito, identifying the disease’s mechanism of transmission. His discoveries earned him a Nobel Prize in 1902. When is World Mosquito Day, instituted by Ross, observed? More… Discuss

Buenos Aires.- Científicos argentinos hallaron un hongo, adaptable a múltiples hábitat, que destruye las larvas de los mosquitos transmisores del dengue y Chikungunya, dos epidemias virales sin vacunas comerciales y cuyo control se basa en la prevención.

Este hongo, denominado “Leptolegnia chapmanii”, puede sobrevivir en aguas turbias o cristalinas, con distintos PH, a temperaturas variables y es cultivable a bajo costo por lo que aparece como una prometedora arma biológica.

Su poder mortífero probó ser efectivo en larvas de 15 especies de mosquitos, entre ellas las del Aedes Aegypti y Aedes Albopistus, vectores del dengue, una enfermedad viral tropical que puede llegar a ser mortal en su variante hemorrágica y es endémica en muchos países. >>>>>>>>>>more HERE<<<<<<<<<<

BUENOS AIRES Argentine scientists have found a fungus, adaptable to multiple habitat, which destroys the larvae of mosquitoes that carry dengue and Chikungunya, two viral epidemics no commercial vaccines and whose control is based on prevention.

This fungus, called “Leptolegnia chapmaniican survive in cloudy or clear waters with varying pH at varying temperatures and is cultivated at low cost so it appears as a promising biological weapon.

Its lethality proved effective in larvae of 15 species of mosquitoes, including Aedes aegypti and Aedes of Albopistus, vectors of dengue, a viral tropical disease that can be fatal dengue hemorrhagic fever and is endemic in many countries.
