HARRISBURG, Pa., March 25 /PRNewswire-USNewswire/ -- The Pennsylvania departments of Agriculture and Health today advised consumers who purchased raw milk from Pasture Maid Creamery in New Castle, Lawrence County, to discard the product immediately because of potential bacterial contamination. Raw milk is milk that has not been pasteurized. A Department of Agriculture lab found the Campylobacter bacteria in a recent milk sample taken from the dairy as part of a human illness...

A Kansas State University study aimed at alleviating intestinal damage in trauma patients digressed to an important finding that could affect medication given to the individuals. Diana Hylton is a K-State senior in microbiology, nutritional sciences and pre-medicine. She is analyzing how the immune system is involved in damage to the intestines following hemorrhagic shock. While studying the effects of a complement inhibitor given following hemorrhage, she found that Helicobacter infection...

Max Planck scientists succeed with a novel technique in the fight against the cause of peptic ulcer disease and gastric cancer A breakthrough in decoding gene regulation of Helicobacter pylori has been made by an international research team led by Jörg Vogel of the Max Planck Institute for Infection Biology in Berlin. Using a newly developed sequencing technique, the re-searchers discovered 60 small ribonucleic acids (sRNAs) - tiny RNA-particles which can regulate genes - in the genome...

Helicobacter pylori (H. pylori) is the causal agent of chronic gastritis, ulcer and gastric cancer. It has the potential to persist in the human stomach for decades, sometimes causing neither harm nor clinical symptoms. Nevertheless, on some occasions, depending on the host immune system and the strain causing the infection, the outcome can be very serious. To maintain the infection, the bacterium must adapt to survive the host defences. One way to accomplish this is to sequentially change...

Gastric cancer, one of the most common types of cancer, is associated with high mortality rates. In the last decades, a decrease in the worldwide incidence has been observed with some changes in the therapeutic and diagnostic options. However, the prognosis for this disease still remains poor, mainly when the diagnosis is performed at advanced stages. The therapy most effective is still surgical resection and in a significant number of cases, especially in the advanced stage, it is only...

The clinical outcome of gastric disease may involve differences in the prevalence or expression of bacterial virulence factors. Contrary to Asian studies, Western studies have disclosed associations between the presence of babA2 gene and gastric cancer. Evidence concerning BabA adhesin-associated genes is insufficient in Costa Rica, where the incidence of gastric cancer is very high, similar to Japan. The babA2 gene, which encodes BabA, may play a role in the development of gastric cancer in...

Despite a strong response from our immune defense, the body is unable to rid itself of the bacterium Helicobacter pylori. One reason for this is that this bacterium encourages elements of the immune response to remain in tissue, activating the wrong immune cells. Research results that pave the way for a future vaccine are now being published by the Sahlgrenska Academy at the University of Gothenburg, Sweden. Approximately half of the world's population are infected with Helicobacter pylori,...

It's been implicated as the bacterium that causes ulcers and the majority of stomach cancers, but studies by researchers at Stanford University, UC Davis, and the University of Pittsburgh have found that Helicobacter pylori (H. pylori) also may play a protective role "“ against the worldwide killer, tuberculosis (TB). In an article appearing online Wednesday in PloS ONE, Jay Solnick, UC Davis professor of medicine and microbiology, and his co-authors report that H. pylori infection may...

A bacterial species that depends on cooperation to survive is discriminating when it comes to the company it keeps. Scientists from Indiana University Bloomington and Netherlands' Centre for Terrestrial Ecology have learned Myxococcus xanthus cells are able to recognize genetic differences in one another that are so subtle, even the scientists studying them must go to great lengths to tell them apart. The scientists' report, which appears in a recent issue of Current Biology, also provides...

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...

Neisseria meningitidis is a heterotrophic gram-negative diplococcal bacterium best known for its role in meningitis and other forms of meningococcal disease such as meningococcemia. It is a major cause of morbidity and mortality during childhood in industrialized countries and is responsible for epidemics in Africa and in Asia. In the US there are approximately 2500 to 3500 cases of N. meningitides infections. Children under 5 are at a higher risk as well as people in the sub-Saharan...

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar error. It was later placed in the genus, Helicobacter. Over 50% of the population has H. pylori in...

Haemophilus influenzae is a Gram-negative, rod-shaped bacterium first described in 1892 by Richard Pfeiffer during an influenza pandemic. It is generally aerobic but can grow as a facultative anaerobe. H. influenzae was mistakenly considered to be the cause of influenza until 1933 when the flu virology became apparent. It was the first free-living organism to have its entire genome sequenced. The project was completed and published in 1995. Two major categories were defined: the...

Haemophilus ducreyi is a fastidious gram-negative coccobacillus causing the sexually transmitted disease chancroid, a major cause of genital ulceration in developing countries characterized by painful sores on the genitalia. Early symptoms are dark and light green shears in excrement. Chancroid starts as an erythematous popular lesion that breaks down into a painful bleeding ulcer. It can be cultured on chocolate agar. It is an opportunistic microorganism that infects through the...
