Latest Proteobacteria Stories
If a human cell and a bacterial cell met at a speed-dating event, they would never be expected to exchange phone numbers, much less genetic material.
40 percent to 60 percent of all cooling water systems tested contain Legionella--the bacterium that causes Legionnaires' disease.
A new study led by researchers at Rhode Island Hospital in collaboration with the University of Rhode Island (URI) and EpiVax. Inc, a privately owned vaccine development company in Providence, RI, has identified a potential vaccine capable of reducing colonization of Helicobacter pylori (H. pylori) -- a known cause of gastritis, ulcer disease and cancer.
Second-hand smoke increases risk of invasive meningococcal disease in children, according to a new study, where authors also found a possible association of second-hand smoke exposure with invasive pneumococcal disease and Haemophilus influenzae type b.
Children exposed to second-hand smoke are more likely to get invasive meningococcal disease than children who are not exposed.
Removing the toxic and odorous emissions of ammonia from the industrial production of fertilizer is a costly and energy-intensive process.
Much as an anthropologist can study populations of people to learn about their physical attributes, their environs and social structures, some marine microbiologists read the genome of microbes to glean information about the microbes themselves, their environments and lifestyles.
A case report in this week's issue of The Lancet, investigates an unusual situation where a man contracted Legionnaire's disease through a cut in his hand while planting with potting compost.
Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer.

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...
