I recently returned from the ASM yearly general meeting in San Francisco. It happens to be 60 years, no less, since I attended my first such event, that one in Chicago. In those days, many members attended a giant banquet as part of the event, I well remember. As a poor graduate student, I could... Read More
Stanley Falkow, Professor Microbiology and Immunology, Geographic Medicine, Infectious Diseases, Stanford University School of Medicine, presents the second part of a lecture on host-pathogen interaction. This one focuses on H. pylori (the ulcer bacterium) and the story behind its discovery by A... Read More
Is bacterial DNA contamination in your whole genome amplification kit a problem? For microbiologists it sure is. WGA is a technique where the complete genomic content of a sample is amplified non-specifically and at a single temperature (isothermically). The presence of any contaminating DNA in ... Read More
