GEMINA - a web-based system of Genomic Metadata for Infectious Agents

GEMINA is a web-based system to identify infectious pathogens and their representative genomic sequences through selection of associated epidemiology metadata. Gemina supports the development of DNA signature-based assays for the detection of pathogens or sets of pathogen through the Insignia Si... Read More

Emerging disease: Looking for trouble

How do you persuade philanthropists to pay $1 million for every pathogenic human virus you discover? Anjali Nayar talks to 'virus hunter' Nathan Wolfe in Cameroon to find out.

Every day, more than 100 patients line up for treatment outside the bare cement walls of a rural health clinic in the... Read More

Viruses of protozoan parasites may exacerbate human disease

Many protozoan parasites (Trichomonas, Leishmania, Giardia, Plasmodium, Entamoeba, Nagleria, Eimeria, Cryptosporidium) are infected with viruses. These viruses do not infect vertebrates, but their double-stranded RNA genomes are sensed by the innate immune system, leading to inflammatory complic... Read More

Peptidoglycan remodeling and conversion of an inner membrane into an outer membrane during sporulation

I just finished listening to the TWiM 35 on LPS in Vibrio (among other topics). Dr. Elio Schaechter mentioned a field in Microbiology that I think is of great interest to the scientific community and should definitely be covered in a podcast. The topic is: Outer Membrane Biogenesis in Gram-negat... Read More

From a food blender to real-time fluorescent imaging

Although Avery, MacLeod, and McCarty showed in 1944 that nucleic acid was both necessary and sufficient for the transfer of bacterial genetic traits, protein was still suspected to be a critical component of viral heredity. Alfred Hershey and Martha Chase showed that this hypothesis was incorrec... Read More
