This diagrams, as a trophozoite, the various forms that the developing malarial parasite undergoes prior to its schizont stage.
As the parasite increases in size, the ring morphology of the early trophozoite disappears, and becomes what is referred to as a mature trophozoite, which undergoes ... Read More
The bug lives harmlessly in the noses of about a third of us. But it can turn rogue, causing skin infections—or worse. Heavy use of antibiotics since the middle of the last century has prompted the evolution of deadly superbug strains. Photograph by Martin Oeggerli, with support from School of L... Read More
