NEW YORK, July 22 /PRNewswire-USNewswire/ -- When a dog or cat bites, an infection can follow. "Wounds that are most likely to become infected are those on the face and hands or when people wait more than eight hours before seeking medical attention," said Dr. Kate Stenske, a clinical assistant professor at Kansas State University's College of Veterinary Medicine. "If you are bitten, first wash the wound thoroughly with soap and water, and then call your physician right away." Stenske...

Clarithromycin is currently one of the antibiotics used for eradication of Helicobacter pylori. However, reports of H. pylori resistance to this antibiotic are increasing worldwide. Clarithromycin resistance has been attributed to the presence of mutations in the 23S rRNA gene, a component of the ribosome that is the protein manufacturing machinery of all living cells. There is little information on the prevalence and characteristics of clarithromycin resistance in H. pylori strains isolated...

About half of the world's population carries Helicobacter pylori, mainly in the stomach. Most infected individuals never experience any symptoms, but around 10% get peptic ulcers and around 1% develop stomach cancer. 'Carriers were often infected as children and if not treated with antibiotics, the bacterium remains in the body for life. The immune system alone is unable to eliminate the bacterium, and now we understand better why', says biologist Bert Kindlund, the author of the thesis.The...

The father of a 14-year-old boy says doctors are desperately trying to save his son from bacteria the teen likely contracted at a North Carolina lake. Brian McKinney told WTVD-TV, Durham, N.C., Wednesday a common bacteria has already forced doctors to remove part of his son Matthew's nose and five of his teeth. It's not every day a doctor says, 'Your son's dying. We're going to try to save his life,' said McKinney, whose son has also lost part of his palate due to the infection. McKinney said...

The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces. This is shown in a thesis at the Sahlgrenska Academy. It is therefore possible to prevent the spread of the bacterium in developing countries through some fairly simple measures.'Taking some cheap but powerful measures may prevent the spread of the bacterium. It could be enough to isolate vomiting patients especially from small children...

 Current research suggests that levels of gastrin play a key role in the development of Helicobacter-induced stomach cancer. The related report by Takaishi et al, "Gastrin is an essential cofactor for Helicobacter-associated gastric corpus carcinogenesis in C57BL/6 mice," appears in the July 2009 issue of The American Journal of Pathology.More than 50% of the world's population is infected with Helicobacter pylori, which causes chronic inflammation of the stomach lining and is strongly...

U.S. researchers say they can prevent ear infections in animals with new vaccines rubbed on the skin. The experimental vaccines were applied in a new way -- a method called transcutaneous vaccination -- which involved placing a droplet of each vaccine onto the ear and rubbing it into the skin Previous work in our lab showed that after immunization by injection, each of the three vaccine candidates prevented experimental ear infections caused by NTHi, study researcher Laura Novotny of the...

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...
