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
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
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
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
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...

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
Out door wood railing was swabbed onto TSA and grown for 48 hrs at 37 degree's C, then allowed to grow at room temperature for 72 hrs the held at refrigerated temperature for a month. This is a close up of some of the organisms that grew. One was a white circular fungal colony with hyphae, the o... Read More
Fungal contaminant seen on Bile Esculin Agar (BEA) after several months at refrigerated temperatures. The fungus was circular at the edges with mounding in the center and blackening of the media indicating esculin hydrolysis. Read More
The TWiP ternion solve the case of the Man from Mexico, and discuss a transgenic toxoplasma vaccine for chickens using Eimeria tenella.
Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is a colorful mucoid orange yeast (possible rhodotorula) slowly overtaking several other colonies (yellow is a presumable yeast as we... 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
