For years, researchers have struggled to get a handle on Group B streptococcus (GBS), in the hopes of improving neonatal outcomes. GBS are a bacteria commonly found in the vagina, rectum, and urinary tract of women. In healthy women, the bacteria are commensal, simply living without causing dise... Read More
Researchers have discovered how the bacteria Group B streptococcus (GBS) avoids detection by the immune system during pregnancy. The findings, reported in the journal mBio, could lead to the development of new drugs and strategies for treating GBS infection, which is a leading cause of neonatal ... Read More
Mold culture growing on top of a home made yogurt culture. Yogurt was made using whole milk and incubated for 8 hrs at a ~30 degree's C then refrigerated. This culture had been in the refrigerator for over 2 weeks, well past expiration for home made yogurt. The green mold had spore formation ... Read More
Washington, D.C.—June 28, 2016—Researchers determined that two bacterial species commonly found in the human mouth and in abscesses, cooperate to make the pathogenic bacterium, Aggregatibacter actinomycetemcomitans, more infectious. Key to the cooperation is that the harmless partner provides th... Read More
Releasing genetically modified mosquitoes appears to have helped reduce cases of dengue in a town in Brazil. The news comes as the US is considering whether to approve the use of the same mosquitoes.
The trial involved Aedes mosquitoes that had been modified to kill off wild mosquitoes of the... Read More

The Centers for Disease Control and Prevention has reported that the wily Neisseria gonorrhoeae bacteria may be developing resistance to the only two antibiotics left that can cure the sexually transmitted disease.
The drugs, azithromycin and ceftriaxone, are used in combination to treat gonorr... Read More
No one knows for sure how they got there. But the discovery that bacteria that normally live in the gut can be detected in the lungs of critically ill people and animals could mean a lot for intensive care patients.
Today, scientists are reporting that they found gut bacteria in the deepest r... Read More
Currently, scientists think the major contributors to insulin resistance are excess weight and physical inactivity, yet ground-breaking new research by an EU funded European-Chinese team of investigators called MetaHit have discovered that specific imbalances in the gut bacteria can cause insuli...

The first case of female-to-male sexual transmission of the Zika virus has occurred in New York City, the Centers for Disease Control and Prevention announced Friday. Up until now, it was thought that the only likely route of sexual transmission was male-to-female or male-to-male.
The surpris... Read More
Washington, DC – July 11, 2016 – A team of Italian investigators has discovered a new variant of an emerging antibiotic resistance mechanism. The new variant, dubbed mcr-1.2, confers resistance to colistin, a last-resort antibiotic against multidrug-resistant Gram-negative pathogens. The researc... Read More
Michael and Vincent present Spotlights, brief reviews of classic papers in the Journal of Bacteriology, and explain how a single bacterial species can reverse autism-like social deficits in the offspring of obese mice.
A team from the Vetmeduni Vienna and the University of Natural Resources and Life Sciences, Vienna succeeded for the first time in extracting the rare compound cPM from a filamentous fungus, applying a special method. Using this substance leads to increased susceptibility of a resistant pathogen... Read More

The anaerobic, Gram-positive Clostridium difficile is a big problem. It causes rampant diarrhea and tissue necrosis, with more than 150,000 annual cases in the United States alone. Many of the disease manifestations of C. difficile are mediated by two exotoxins that C. difficile produces: TcdA a... Read More
Floor swab was done for a science project. One of the organisms seen was mucoid, opaque in color and had finger like projections (swarming) after growth on TSA at 37 degree's C for 48 hrs. Read More
After seeing living microbial mats forming stromatolites in Yellowstone in Part One, now we go back in time to the Jurassic period - hunting for microbial fossils in the desert of Utah. It's Part Two of the National Park anniversary series, live on the ASM blog! #NPS100 Read More
Serratia marcescensgrown on TSA for 48 hrs. at 37 degree's C then held at room temp for 24 hrs. Serratia marcescens is circular, mucoid and has a red to oragne pigment due to the production of prodigiosin. Usually the red coloration dose best at reduced temperatures so after initial grown at ... Read More
