Magnified 475X, this photomicrograph depicts some of the structural morphology of numerous Trichophyton violaceum fungal organisms. This dermatophyte had been grown in a medium of Sabouraud dextrose agar, and of note are the organism’s mycelia, or branching hyphae, i.e., the vegetative portion o... Read More

Scanning electron microscopy photograph of a human isolate of Naegleria fowleri amoeba grown in axenic culture displaying sucker-like structures, called amoebastome, used for a novel form of phagocytosis. There appears to be an inverse correlation between the mean number of suckers per amoeba an... Read More

Unstained, temporary wet mount showing size relationship between yeast cells (Saccharomyces) and bacterial rods (Bacillus subtilis). (approx. X 100). Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. Read More
I created these two plate cultures for a "most popular" photo scholarship contest on the web and amazingly I have received a nice popularity score thus far. The plates are of Eosin Methylene Blue Agar media with Escherichia coli as the stem and leaves and Salmonella paratyphi as the petels. If... Read More

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
