Bacteria have developed countless strategies to hide themselves in order to evade attack by the immune system. In the body, Salmonella bacteria use macrophages as host cells to ensure their survival and to be able to spread within the body. Their survival strategy is to nestle into a vacuole wit... Read More
It is universally accepted that the use of antibiotics will lead to antimicrobial resistance. Traditionally, the explanation to this phenomenon was random mutation and horizontal gene transfer and amplification by selective pressure. Subsequently, a second mechanism of antibiotic-induced antimic... Read More
An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the green and yellow grainy spore formation in the center of the colony with exudate ...

In Pakistan prevalence and drug resistance of TB is on the rise. Late diagnosis and lack of resources are making the situation worse. In such a scenario molecular techniques such as PCR and hybridization would help in early diagnosis of TB and MDR TB leading to commencement of treatment at the r... Read More
From the discovery of the first Neanderthal skull in a Belgian cave in 1826, a bone of contention among Homo sapiens has been the extent of our relationship to Homo neanderthalis, who disappeared from the fossil record ~30,000 years ago. Like scrappy cousins we'd rather not claim, we've attempte... Read More
BERKELEY — People infected with the Human Immunodeficiency Virus (HIV) can stave off the symptoms of AIDS thanks to drug cocktails that mainly target three enzymes produced by the virus, but resistant strains pop up periodically that threaten to thwart these drug combos. Researchers at the Unive... Read More
Getting the message out to the public that the microbial world is about much more than just diseases is a challenging topic, but one we should keep trying to improve on. There are many ways to do this, but as the saying goes, a picture is worth a thousand words, and most people don’t want to rea... Read More
Recent salmonella outbreaks that sickened at least 523 people and sent dozens to the hospital underscore “serious weaknesses” in the U.S. Department of Agriculture’s oversight of poultry plants, according to a study released Thursday by the Pew Charitable Trusts, which also criticized the govern...

An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the red/pink grainy spore formation in the center of the colony. This sample grew at ...

The abilities of bacterial organisms to utilize the various strategies to resist antimicrobial compounds are all genetically encoded.
Intrinsic resistance is that type of resistance which is naturally coded and expressed by all (or almost all) strains of that particular bacterial species. An... Read More

A nasty virus first detected in Africa that is spread to people by the bite of infected mosquitoes is being locally transmitted in the Americas for the first time on the tiny French Caribbean dependency of St. Martin, health officials said Tuesday.
Epidemiologists have so far confirmed about ... Read More
Inspired by natural materials such as bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots.
These “living materials” combin... Read More
In addition to storing films, optical discs can be used to detect microorganisms, toxins, allergens and tumoral biomarkers. Blu-ray technology has allowed researchers to develop a way to find out if a sample contains Salmonella or toxic substances. This simple and cheap analytical system may be ... Read More
