The related virus Japanese encephalitis virus is the most important cause of mosquito-borne encephalitis in the world, and is maintained in avian reservoirs and amplified by pigs. The occasional spill-over of the virus into humans results in more than 60 000 clinical cases of Japanese encephalitis annually, with high case fata...

... RNA extracted from each mosquito larvae pool was tested by nested PCR for detection of dengue virus. Out of total 50 pools of Aedes aegypti larvae, DV-2 was the most prevalent serotype. DENV-1 was not found in any pool. While all pools of Aedes albopictus were negative for dengue virus. Our study showed that the main cause of spreading of dengue virus was Aedes aegypti. Serotype DENV-2 was dominant in the field collected larvae of Aede...

Valley fever (RVF) is a mosquito-borne emerging disease, capable of causing large epidemics in livestock accompanied by cases in humans, but with a complex cycle of transmission that makes it difficult to predict. The risk of infection in humans is more with livestock handlers who get occupationally exposed to Rift Valley fever virus (RVFV) because of frequent contact with infected vectors, animal body fluids and other tissues. We aimed to determine the preva...
