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

This thin-section transmission electron micrograph (TEM) revealed the ultrastructural appearance of a single virus particle, or “virion”, of measles virus. The measles virus is a paramyxovirus, of the genus Morbillivirus. It is 100-200 nm in diameter, with a core of single-stranded RNA, and is c... Read More
Recently recognized outbreaks, or clusters of MRSA in community settings have been associated with strains that have some unique microbiologic and genetic properties, compared with the traditional hospital-based MRSA strains, which suggests some biologic properties, e.g., virulence factors like ...
