This animation starts with the explanation of bacterial cell wall synthesis, the process targeted by ß-Lactams.
Structurally, most bacteria consist of a cell membrane surrounded by a cell wall and, for some bacteria, an additional outer layer. Internal to the cell membrane is the cytoplasm whi... Read More

Methicillin-resistant Staphylococcus aureus likes to hide in other moist places besides the anterior nares, especially the throat, perineum, armpits, and under pendulous breasts. To determine if a patient with recurrent MRSA abscesses or other skin infections is truly a carrier and thus a candid... Read More

Marine shallow water sandy bottoms on the surface appear desert-like and empty, but in the interstitial space between the sand grains, a diverse fauna flourishes. In addition to bacteria and protozoa, numerous animal phyla have been found here - some found only here. One of the strangest members... Read More

Modernization in developing countries may be accompanied by a transition from epidemic infectious diseases to chronic and degenerative illnesses as predominant causes of morbidity and mortality. The hygiene hypothesis posits that reduced exposure to infectious agents in childhood as a result of ... Read More
The ability of bacteria to be genetically manipulated in a directed way has permitted the application of bacterial metabolism and gene expression to the creation of products useful in a wide variety of domains, including alternative energy generation, novel and manipulatable pathways for antibio...

Large concentrations bacteria identified in the nuclei of hailstones suggest that airborne microorganisms may be responsibility for the formation of these weather events. Participants will discuss these findings as well as the implications they may have for understanding of the role microbes pl... Read More
While the pathogen Chlamydia pneumoniae has been linked to asthma in the past, new research finds over two-thirds of people with severe asthma test positive for Chlamydia-specific antibodies, suggesting this antigen could be a good biomarker for detecting those at risk for asthma. Additional re... Read More
