Lactate produced in the upper throat might trigger meningitis-causing bacterial cells to detach from tiny colonies and spread within the body, according to a new study published in PLOS Pathogens.
The research, performed by Sara Sigurlásdóttir and colleagues at Stockholm University in Sweden,... Read More
The first live-attenuated Zika vaccine still in the development stage completely protected mice against the virus after a single vaccination dose, according to new research from The University of Texas Medical Branch at Galveston and Instituto Evandro Chagas at the Ministry of Health in Brazil. ...

Researchers from Harvard Medical School have discovered that the body's immune system initially detects the presence of anthrax spores by recognizing RNA molecules that coat the spores' surface. But this prompts an unfavorable immune response that hinders the body's fight against anthrax once th... Read More
Over the last ten-plus years of this blog's existence, one cluster of branches on the bacterial phylogenetic tree in particular has presented us with fascinating mysteries regarding basic, and seemingly unique, cellular biology. Many aspects of the species on these branches remain enigmati... Read More
Bacteria of the microbiome are essential aspects of human health. The best example is in the human gut. Home to nearly three pounds of bacteria (with recent estimates at 3.8·1013 bacteria), our gut uses its microbiome to neutralize toxic byproducts of digestion, stimulate digestion, assist with ...

Close up of a white fungal contaminants seen on Bile Esculin agar (BEA) after several month at refrigerated temperature. The BEA agar did turn black indicating esculin hydrolysis. This colony mounded in a cone shape with rhizoid growth towards the top and mat lobate growth around the edges. Read More
At Cornell University in Ithaca, New York, Vincent speaks with Susan, Colin, and Gary about the work of their laboratories on parvoviruses, influenza viruses, and coronaviruses that infect dogs, cats, horses and other mammals.

Several recently published mBio studies describe new mechanisms of intrinsic antibiotic resistance. These mechanisms may themselves become therapeutic targets to broaden the application of currently available drugs. Read More
Simon Anthony has spent his scientific career studying viruses and their impact on health. In the United Kingdom, where he is from, he investigated viruses of agricultural significance. Then, at the San Diego Zoo, he focused on the microbes of wildlife. Currently, at Columbia University’s Mailma... Read More
Though it's been less covered by major news outlets, Zika is still an important research topic. Scientists are working hard to understand Zika virus biology, transmission, and treatment. We round up the latest research reports on this still-emerging disease. Read More
This was a swab taken form the bottom of a shoe incubated for 48 hrs at 37 degrees C then held at room temp for 48 hrs then held at refrigerated temp's. A variety of colony morphology is seen, rhizoid, mucoid, etc. Image taken using transmitted light. Read More

This is a primer on the mycorrhizae, the association of plant roots and fungi. An outstanding review article on this subject has recently appeared, authored by four Frenchmen and one American: F. Martin, A. Kohler, C. Murat, C. Veneault-Fourrey, and D. S. Hibbett. I found reading it both excit... Read More
The TWiM team speaks with Pat Schloss about assigning sequence data to operational taxonomic units, and his experience with mSphere Direct, a new way of submitting papers for publication.
The TWiVome discuss the blood virome of 8,420 humans, and thoroughly geek out on a paper about the number of parental viruses in a plaque.
Please submit your best bacterial masterpiece to the American Society for Microbiology's annual Agar Art contest!
Shown here is Vibrio fischeri grown on extra salty LB that was stategically dyed purple with Crystal Violet and accentuated with colored markers. Read More
Embryonated egg of Ascaris lumbricoides. (Larva is motile inside the shell when seen under microscope)
It is infective stage of Ascaris. On ingestion the cortication is dissolved by gastric acid and the larva inside the egg is released. Fertilized eggs freshly passed in stool are non infective.... Read More
One of the conundrums facing TB research is the fact that Mtb grows incredibly slowly. Slow growth confounds both research and treatment since it can take days to weeks to grow a culture for study, a month or more to determine drug resistance properties of a patient sample, and months of antibio...
