Fungus knocks a frog down but not out, raising questions about amphibian declines

...rog went extinct, and T. eungellensis suffered its severe decline, yet another species in the area, Litoria lesueuri, was apparently completely unaffected by the fungus, despite a high rate of infection in that species. This suggests that some species may tolerate the pathogen, which raises questions about...

Research team develops nonhuman primate model of smallpox infection

...doses of the virus. Both variola strains produced severe disease, with almost uniform lethality and end-stage lesions resembling the human disease, in monkeys exposed by the combined route of infection. According to the authors, death usually occurred within six days of inoculation. Similar results were se...

...d to be reliable at predicting mortality. However, severe lethargy was apparent one to two days prior to death. And while there was a "marked, age-dependent effect on mortality, there was no effect at all on morbidity, which was somewhat surprising," Woods said. The Illinois researchers plan on doing follo...

Interactive health information system to detect Japanese encephalitis in Asia

...itis kills one-third of those infected, and causes severe disabilities in half of those who survive. To successfully combat Japanese encephalitis, health officials need surveillance networks that allow them to respond quickly to reported cases and readily identify outbreaks. Voxiva has deve...

Embryonic stem cells correct congenital heart defect in mouse embryos

By 7 days old, the expression of proteins normally found in cartilage was reduced, although at this stage the knee, for example, looked normal. By 7 weeks old (adulthood for mice), there were clear structural changes in the kne...

To save dolphin's dorsal fin experts combine medical technology and teamwork
