The enzymes that make copies of the DNA or RNA genomes of viruses – nucleic acid polymerases – can be placed into two broad categories depending on whether or not they require a primer, a short piece of DNA or RNA, to get going. The structure of the primer-independent RNA polymerase of hepatitis... Read More
Look what the cat dragged in! The parasite Toxoplasma gondii, a common protozoan transmitted by cats, can effect mammalian brain cells in strange ways. In rodents, the parasite has been shown to inhibit fear and actually attract them to the smell of cat urine. Humans can be infected through c... Read More
Nasal drops of harmless bacteria can inhibit a related bug that sometimes causes meningococcal disease, according to new findings published online in Clinical Infectious Diseases. The study--conducted among college students, a group at higher risk for this often serious illness--suggests a new a... Read More
Feeling lonely! Just remember you are not alone. A huge number of bacteria live in your body, and most of them are in your intestine. But you do not need to be worried about it, because they will not hurt you in a normal situation. In fact, the relation between humans and their microbiota is an... Read More
For people infected with the human papilloma virus (HPV), the likelihood of clearing the infection and avoiding HPV-related cancer may depend less on the body's disease-fighting arsenal than has been generally assumed. Read More
Researchers at Princeton have discovered that cytomegalovirus manipulates a process called fatty acid elongation, which makes the very-long-chain fatty acids necessary for virus replication. Published in the journal Cell Reports on March 3, the research team identified a specific human enzyme--e... Read More
Happy World TB Day! Happy because, today in 1882, notable Microbiologist Robert Koch announced his discovery of the culprit bacteria that causes tuberculosis. This photo is a Zeihl-Neelsen stain of bronchial lavage (1000x). The pink/red is the mycobacteria, and the blue/purple is background.

Growth Inhibition of Streptococcus pyogenes by Bacitracin. Streptococcus pyogenes is sensitive to bacitracin and will not grow around the antibiotic-containing disc. The other beta hemolytic streptococci are not sensitive to bacitracin. Isolated of Beatrice Rogolino M.Sc - photo Francesco d'Aleo... Read More

U. MINNESOTA (US) — One effective way to fight the spread of antibiotic-resistant bacteria, known as “superbugs,” may be to treat municipal wastewater solids at higher temperatures. Heating the solid waste to 130 degrees Fahrenheit (55 degrees Celsius) was particularly effective in eliminating ... Read More
So I told ccondayan I would post something lewd to MicrobeWorld (who probably thought I was joking). And what could be more lewd than genuine smut? Of course, since this is MicrobeWorld, I'm posting about the group of fungal plant pathogens referred to as smut. When I worked in a plant pathol... Read More
Leprosy is a chronic infection of the skin, peripheral nerves, eyes and mucosa of the upper respiratory tract, affecting over a quarter million people worldwide. Its symptoms can be gruesome and devastating, as the bacteria reduce sensitivity in the body, resulting in skin lesions, nerve damage ... Read More
A team of scientists including Virginia Tech researchers is one step closer to understanding how bacteria on a frog's skin affects its likelihood of contracting disease. Read More
When calves are infected by two parasite species at the same time, one parasite renders the other far less deadly, according to a new study published in the current journal of Science Advances Read More
Chlorine, a disinfectant commonly used in most wastewater treatment plants, may be failing to completely eliminate pharmaceuticals from wastes. As a result, trace levels of these substances get discharged from the plants to the nation's waterways. And now, scientists are reporting preliminary st... Read More

Your gut is a genius. Inside it exists an astonishing ecosystem of trillions of micro-organisms—more than 10 times the number of human cells in our bodies! This ecosystem of microbes—the human gut microbiota—deeply influences our phy... Read More
