Vincent, Dickson, and Daniel consider the delivery of anti-trypanosome nanobodies to the tsetse fly via a bacterial symbiont, and present a new case study.
Ten years ago this month I wrote the first post at virology blog, entitled Are viruses living? Thanks to EE Giorgi for pointing out the ten year anniversary, and also for publishing an interview with me at her blog, Chimeras. Here is how this blog got started. Read More
Unknown organism isolated from a swab taken off the bottom of a shoe. Students were asked to swab something in the classroom. One swab was done on the bottom of a shoe and incubated on a TSA plate for 48 hrs at 37 degree’s C. The organism was difficult to scrape so a small chunk of the organis... Read More
Tara Smith joins the TWiEBOVsters to discuss the Ebola virus outbreak in west Africa, spread of the disease to and within the US, transmission of the virus, and much more.
A streak plate of Strep pyogenes on blood agar, stock culture used for class, was kept at room temp for 1 month. Before disposal a contaminant, presumably environmental, was seen on the plate. The pigment was opaque tan/yellow and with a mucoid surface. Lobate marigins with raised irregular-rh... Read More

Many people have heard that human urine is devoid of germs, but a new study seems to question that idea.
"Doctors have been trained to believe that urine is germ-free," Dr. Linda Brubaker, dean of Loyola University Chicago Stritch School of Medicine, said in a university news release. "These ... Read More

Organisms grown in Fluid Thioglycollate Media w/out resazurin dye is a reducing media that uses sodium thioglycollate to chemically combine with dissolved oxygen to deplete the oxygen in the media. All organism except for Neisseria sicca were grown for 48 hours at 37 degrees C. Neisseria sicca i... Read More

The TWiVers discuss the growing Ebola virus outbreak in West Africa, and an epidemic of respiratory disease in the US caused by enterovirus D68.
Laurene Mascola's distinctive voice and laugh has won my heart this month. I found that when TWiM came up for the third time in my playlist the last couple weeks, I kept listening just for a fix. She should be a star.
I'm glad you had a good reaso... Read More
Melanin produced by a marine bacteria Bacillus spp. has shown shown to have good anti-inflammatory activity. The pigment had shown to inhibit inflammatory enzymes cycloxygenase, lipooxygenase, myeloperoxide,NO synthase in vitro at a concentration which was non-cytotoxic..This will be a breakthro...

When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
