A genomic investigation has revealed that a lethal parasite infecting a wide range of insects actually originated from pond scum, but has completely shed its green past on its evolutionary journey.

Intracellular parasites and bacteria deploy an array of molecular tactics to invade host cells. Once inside, these pathogens subvert and co-opt host resources for survival and reproduction. Stealthy ...

To identify a complex virus in Figure 13.1, one must look for specific structural features that differentiate it from simpler viral architectures. Complex viruses do not adhere to the regular ...

The immune system's killer cells deliver a tightly controlled, 3-phase knockout punch that kills intracellular parasites through a novel pathway that an international team led by researchers from the ...

Amoebae receive surprising support in defense against viruses: The bacteria they are infected with prevent them from being destroyed by giant viruses. A research team led by microbiologist Matthias ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 91, No. 17 (Aug. 16, 1994), pp. 7859-7863 (5 pages) We targeted the mini-exon sequence, present at the 5' end of ...

Toxoplasma gondii is an obligate intracellular parasite which, to survive, must absolutely penetrate its host's cells. Understanding how the parasite manages to enter host cells offers opportunities ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 98, No. 17 (Aug. 14, 2001), pp. 9599-9604 (6 pages) The nonstructural protein 5A (NS5A) encoded by the human ...

For at least 3,000 years, humans have known that malaria runs like clockwork, with a devastating fever that peaks, fades, and returns on a predictable schedule. The Greek physician Hippocrates ...
