American Society for Microbiology honors George Liu

...ction. He worked on dissecting the function of Group B streptococcus (GBS) hemolysin. He showed that this toxin has an unusual dose effect that causes lysis of phagocytes at a higher dose, apoptosis at an intermediate dose, and downregulation of inflammation at a low dose. The golden color imparted by car...

Study reveals how viruses collectively decide the fate of a bacterial cell

...ions change, which can result in a switch to the lytic pathway. The decision of the genetic circuit that controls whether a virus initially chooses lysis or lysogeny is not random. Instead, cell fate is controlled by the number of infecting viruses in a coordinated fashion, according to the new study, w...

Gene that helps mosquitoes fight off malaria parasite identified

...delayed the process of parasite lysis, whereby the mosquito rids itself of the parasite. "This study furthers our knowledge of the malaria-parasite lysis in mosquitoes. It may help provide better tools for controlling the disease in the future," said lead author Eappen G. Abraham, PhD, research associat...
