Enterococcus faecalis

The bacterium, Enterococcus faecalis, which lives in the human gut, is just one type of microbe that will be studied as part of NIH's Human Microbiome Project. Read More

A Microbial Hallowe'en, Part I

My mathematician wife "painted" onto a marine nutrient plate using a bioluminescent bacterium---as you can see, she loves Einstein. And I love microbiology. Hence the intersection! Read More

This digitally-colorized scanning electron micrograph (SEM) depicted a small grouping of Gram-negative Sebaldella termitidis bacteria.
Recently, “the genome of ATCC 33386 S. termitidis was recently sequenced as part of the U.S. Department of Energy - Joint Genome Institute’s (DOE-JGI) Genomic E... Read More

Malabaricus Grouper Nervous Necrosis Virus

The foreground shows the density map (gold) from a cryoelectron micrographic reconstruction of malabaricus grouper nervous necrosis virus, a fish nodavirus. The background shows the fitting of a two-domain model consisting of a protruding domain and a β-sandwich domain into the reconstruction de... Read More

Influenza Virions (1973)

This colorized negative-stained transmission electron micrograph (TEM) depicts the ultrastructural details of a number of influenza virus particles, or “virions”. A member of the taxonomic family Orthomyxoviridae, the influenza virus is a single-stranded RNA organism

Listeria monocytogenes against brain macrophages.

Listeria monocytogenes has a particular tropism for the central nervous system. To gain knowledge about the immune response elicited by L. monocytogenes in the brain, we used a rat ex-vivo organotypic nervous system culture as a model for Listeria infection. Brain sections were maintained severa... Read More

A dangerous bridge for Serratia.

Serratia spp. are widely distributed in nature. Serratia marcescens is the most common Serratia sp. associated with human disease, followed by strains of the S. liquefaciens complex: S. liquefaciens, S. grimesii and S. proteamaculans. The clinical significance of these species is largely unknown... Read More
