Viruses a major source of human evolution

In disease ecology, we learn that the interaction between hosts and parasites can shape communities and drive evolution. In the so called coevolutionary arms race, the parasite or pathogen optimizes its ability to infect hosts while hosts face selective pressure to adapt defenses. An example of this can be seen in the flu virus, where … More Viruses a major source of human evolution

Detection of Reservoir Species for Hepatitis E Virus in China

The research paper done by Xia et al published in 2015 addresses the prevalence of Hepatitis E virus (HEV) in animals in China. HEV is a single stranded, positive-sense RNA that is usually transmitted by the fecal-oral route. Four different genotypes of the virus has been isolated so far. Genotypes 1 and 2 occur in … More Detection of Reservoir Species for Hepatitis E Virus in China

Fungi may be able to control mosquito population

Mosquitoes are often seen as worthless insects, whose only objective in life is to feed on our blood. Though only the females take blood meals, they are also responsible for transmitting many pathogens.

A Gut Feeling; Worms, Mutualistic or Parasitic?

Would you believe a parasitic worm might actually treat crohn’s disease? Previously, worm infections were known to increased susceptibility of multiple parasite infections. Now current research has scientists reevaluating the symbiotic relationship between humans and infectious worms. Dr. P’ng Loke, a parasite immunologist at New York University School of Medicine, conducted an experiment on two different … More A Gut Feeling; Worms, Mutualistic or Parasitic?
