Escherichia coli bacteria thrive in the lower intestine of humans and other animals, including birds. Most are vital constituents of the healthy gut flora, but certain forms of E. coli cause a range of diseases in both humans and poultry. In this month´s issue of the journal PLoS ONE, a team of researchers at Arizona State University´s Biodesign Institute investigates disease-causing E. coli strains known as APEC (for Avian Pathogenic E. coli).  By studying circular segments...

Patterns Of Antibiotic-resistant Bacteria Found In Some Galapagos Reptiles
2012-01-24 04:02:28

Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Galápagos islands are more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report in a new study. Feces collected at several different sites from free-living reptiles harbored Escherichia coli bacteria that were resistant to ampicillin, doxycycline, tetracycline, and trimethoprin/sulfamethoxazole....

Findings could provide basis for first treatment for Shiga toxin infection Carnegie Mellon University researchers have discovered that an element commonly found in nature might provide a way to neutralize the potentially lethal effects of a compound known as Shiga toxin. New results published in the Jan. 20 issue of Science by Carnegie Mellon biologists Adam Linstedt and Somshuvra Mukhopadhyay show that manganese completely protects against Shiga toxicosis in animal models. Produced by...

Alpha-hemolysin triggers bladder cell shedding Researchers from the University of Utah have identified a process by which the most common types of urinary tract infection-causing bacteria are able to trigger bladder cell shedding and disable immune responses. According to this new study, published in the Jan. 19, 2012, issue of Cell Host & Microbe, α-hemolysin, a toxin secreted by many strains of Escherichia coli (E. coli), may play an important, unexpected role during...

Deutsch Foundation-Sponsored Work Offers Multi-Pronged Attack on Major Medical Problem COLLEGE PARK, Md., Jan. 18, 2012 /PRNewswire-USNewswire/ -- In helping people with serious medical problems, doctors depend on catheters to deliver medications, carry away bodily wastes and monitor vital signs. However, the very catheters that are so important to their patients' health can themselves be infected by bacteria and become sources of serious and costly complications. Researchers at the...

Antibiotics in pig feed increased the number of antibiotic resistant genes in gastrointestinal microbes in pigs, according to a study conducted by Michigan State University and the U.S. Department of Agriculture´s Agricultural Research Service. Published in the current edition of the Proceedings of the National Academy of Sciences, the comprehensive study focused on understanding the effects of conventional, in-feed antibiotics in U.S. farms. For decades, many producers of pigs,...

A short burst of low voltage alternating current can effectively eradicate E. coli bacteria growing on the surface of even heavily contaminated beef, according to a study published in the International Journal of Food Safety, Nutrition and Public Health. The technique offers an inexpensive and easy to implement approach to reducing the risk of food poisoning, which can occur despite handlers complying with hygiene standards. Food poisoning is a serious public-health issue, especially with...

Could lead to a test and therapy for kidney failure caused by E. coli New findings by St. Michael's researchers about the way cells work could lead to a test and therapy for kidney failure caused by E. coli. Ever since the water supply in Walkerton, Ont., was contaminated by E. coli in 2000, Dr. Philip Marsden has been trying to figure out just how a toxin released by that particular strain of the bacteria causes kidney damage in children. Now Dr. Marsden and his team based at St....

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose fermenting, facultative anaerobic, rod shaped bacterium found in the normal flora of the mouth, skin, and intestines. It is the most important member of the Klebsiella genus of Enterobacteriaceae. It is naturally occurring in soil and about 30% of strains can fix nitrogen in anaerobic conditions. Hans Christian Gram developed the technique now known as Gram staining in 1884 to discriminate between K. pneumoniae and...

Escherichia coli is a Gram-negative rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless; however, some such as O157:H7 can cause food poisoning in humans and are often responsible for product recalls. The normal flora of the gut normally contains the harmless strains and often provide K2 to the body. They are not always confined to the intestine and have the ability to survive briefly outside of the body. It grows easily...
