PROVIDENCE, R.I. [Brown University] -- A new study of the relationship between violent conflict and HIV incidence in sub-Saharan Africa finds that HIV incidence may be at its worst in the period before hostilities break out. The Brown University analysis reports that the rate of new infections r... Read More

Athens, Ga. - People feeding white ibises at public parks are turning the normally independent birds into beggars, and now researchers at the University of Georgia say it might also be helping spread disease. Read More
What if a single vaccine could protect people from infection by many different viruses? That concept is a step closer to reality. Read More
Unknown organism, possible Bacillus spp, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was a light brown and mat. The center of the growth was smooth with rhizoid like growth on the edges which were mucoid... Read More
Unknown organism, possible yeast or Bacillus, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow and mucoid . There are numerous rings of growth (looks like layers of rope) with lobate margins.... Read More
Unknown organism, possible yeast, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow, mat in the center and mucoid towards the outside. There are several rings of growth with each ring havin... Read More
this was my first time isolated bacterial plate from strawberry fruit harvested from the field of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU),Bangladesh. My love at first sight for bacteria. Read More
The Nature of Death explores the possibilities of life being created through death. With the growth of similar looking bacteria in my samples, I am able to exhibit that life grows post-mortem and allows beautiful nature to coalesce around it. Having taken samples of gravestones of a U.S. World W... Read More
An international study led by University of Queensland (UQ) researchers has tracked the re-emergence of a childhood disease which had largely disappeared over the past 100 years. Read More

At the University of Cologne, biophysicists in the lab of Professor Berenike Maier were now able to show how differential mechanical forces can lead to cell sorting in biofilms, thereby determining their architecture. In their publication in the journal eLife, the team headed by the biophysicist... Read More
I would like to see a Twitter hash tag for microbiologically themed Jack-o-Lanterns for Hallowe'en!
In my Microbiology course here at the University of Puget Sound, my student Ruth created this bacteriophage inspired pumpkin art.
#HappyMicrobialHalloween, everyone! Read More
I enjoy mixing Hallowe'en with my classes. In this blog post, I show how my microbiology students do exactly that, with humor and style. In addition, my freshman writing students do the same with their course on symbioses and parasitism. Enjoy...and #HappyMicrobialHalloween! Read More
