Latest Gram negative bacteria Stories
Just in time for the holidays, PineNutOil.org is offering customers the chance to buy three bottles of pine nut oil enriched with sap, and receive one at no cost.
An ongoing salmonella outbreak that has been linked to a California chicken producer highlights the need for more action to be taken by federal regulators to step up food safety rules and regulations to protect American consumers.
In the past decade, a single strain of Escherichia coli, or E. coli, has become the main cause of bacterial infections in women and the elderly by invading the bladder and kidneys
Wolbachia, a symbiont that resides naturally up to 70% of all insect species, are probably the most prevalent infectious bacteria on Earth.
E. coli is one of millions of bacterial species that live in our gut. From when we are infants, E. coli dwells peacefully in the lower intestine, maintaining a give-and-take relationship with our body – it helps the gut digest food, and gets energy to live and reproduce in return.
Legionella bacteria were recently responsible for two new Legionnaires’ disease outbreaks.
Scientists have used a new method to map the response of every salmonella gene to conditions in the human body, providing new insight into how the bacteria triggers infection.
Holiday times are stressful on everyone, and keeping the food prep area germ free has become more challenging in the 21st century, where germs can travel faster than a Concorde SST.
Arizona State University scientists have developed a microfluidic chip, which can sort good germs from bad.
A recent issue of the journal Gut Microbes, featured in an article on news-medical.net, provides new insights into the pathophysiology, diagnosis, prevention and treatment of Helicobacter pylori
Wolbachia is a genus of bacteria which infects arthropod species, including a high proportion of insects (~60% of species). It is one of the world's most common parasitic microbes and possibly the most common reproductive parasite in biosphere. Studies have suggested that 25-70% of all insect species are estimated to be potential hosts. Marshall Hertig and Burt Wolbach first identified the bacterium in 1924 in a species of mosquito. Hertig described the genus as Wolbachia pipientis. Not...
Serratia marcescens is a species of Gram-negative, rod-shaped bacterium in the family Enterobacteriaceae. S. marcescens is involved in nosocomial infections particularly catheter-associated bacteremia. It is commonly found in respiratory and urinarty tracts of hospitalized adults and often in the gastrointestinal system of children. It is commonly found growing in bathrooms due to its preference for damp conditions. It manifests as a pink discoloration and a slimy film feeding off...
Salmonella enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella and many of the pathogenic serovars of the S. enterica species are in this subspecies. Serovars can be designated fully or in a shortened form. The genus, Salmonella, is on the short form lists which are followed by the capitalized and non-italicized serovar. Each serovar can have many strains as well, which allows for a rapid...
Rickettsia rickettsii is a gram-negative bacterium native to the New World and causes the malady known as Rocky Mountain spotted fever (RMSF). It is transmitted through the bit of an infected tick when it feeds on animals and humans. Humans are not necessary hosts in the rickettsia-tick life cycle but they can be. S. Burt Wolbach created the first detailed description of the etiologic agent in 1919. He recognized it as an intracellular bacterium seen most frequently in endothelial cells....
Pseudomonas aeruginosa is a common bacterium that can cause disease in animals and humans. It can be found in soil, water, skin flora, and most man-made environments throughout the world. It thrives in normal or hypoxic atmospheres; due to this it has colonized many natural and artificial environments. It can infect animals with damaged tissue or people with reduced immunity. Symptoms are generalized inflammation and sepsis. It can be fatal if colonization occurs in critical body organs,...
