A specific protein on the surface of a common bacterial pathogen allows the bacteria to leave the bloodstream and enter the brain, initiating the deadly infection known as meningitis. The new finding, which may guide development of improved vaccines to protect those most vulnerable, including young infants and the elderly, is now available online in the Journal of Experimental Medicine."Streptococcus pneumoniae, commonly known as pneumococcus, is responsible for half the cases of bacterial...

British medical scientists say they have discovered how meningococcal bacteria break through the body's natural defense system to attack the brain. University of Nottingham researchers said their discovery could lead to better treatment and vaccines. The scientists said it can take just hours after symptoms appear for someone to die from bacterial meningitis, which in childhood is nearly exclusively caused by the respiratory tract pathogens Streptococcus pneumoniae, Neisseria meningitidis and...

A rising number of U.S. parents not vaccinating their infants are placing children at risk for Hib infections, health officials say. Although Hib infection, or Haemophilis influenzae type B, was thought to be wiped out through widespread vaccination, five cases of the infection, one of them fatal, were reported in Minnesota last year, USA Today said Monday. Three of the infected children, including a 7-month-old who died, had not been immunized against Hib. Some parents wonder if these...

Health officials in Minnesota say they're checking to see if deadly Hib infections have been reported in children in other states. Minnesota last year recorded five cases of infection from Haemophilus influenzae Type B, including the death of a 7-month-old -- the first child Hib fatality in the state since 1991, The Washington Post reported Saturday. The dangerous bacterium's return may be a consequence of a temporary vaccine shortage and a resistance by some parents to immunize their...

Researchers say a strain of bacteria causing pneumonia and meningitis in children is on the rise in England and Wales.A vaccine introduced in 2006 has effectively cut the number of infections in children. But researchers say cases caused by a pneumococcal type not covered by the vaccine seem to be increasing.The U.S. has noted similar patterns and new vaccines are in development.The pneumococcal vaccine protects against seven types of Streptococcus pneumoniae and is given to infants at two...

Nearly 100 percent drop in Hib meningitis as a result of widespread vaccinationHib meningitis has been virtually eliminated in young children in Uganda just five years after the country introduced Haemophilus influenza type b (Hib) vaccine nationwide, according to an independent study.Haemophilus influenza type b is a leading cause of pneumonia and meningitis, an inflammation of the lining covering the brain and spinal cord. Each year, Hib kills approximately 400,000 children under five years...

By Ohnsman, Christina Ritterband, David; O'Brien, Terrence; Girgis, Dalia; Kabat, Al Key words: Azithromycin - Conjunctivitis - Fluoroquinolone - Macrolide - Moxifloxacin - Resistance ABSTRACT Objective: To examine in vitro resistance to azithromycin and moxifloxacin in bacterial conjunctivitis isolates. Methods: MIC^sub 90^s (Minimum Inhibitory Concentration) and resistance rates to azithromycin and moxifloxacin were determined based upon microtiter broth dilution and/or antimicrobial...

Millions of bacteria live within the recesses of our noses and upper respiratory tracts, waiting for a chance to infiltrate and infect. But long before these bacteria break through our immune defenses, they must first compete against other bacterial species to colonize the mucus-lined surfaces of our noses. Competition between two common nose bacteria involves some interesting trickery, according to a new study in PLoS Pathogens. "We're looking at how bacteria use their host, and we've found...

Streptococcus pneumoniae, or pneumococcus, is Gram-positive, alpha-hemolytic, bile-soluble aerotolerant, anaerobic member of the genus Streptococcus. It was recognized as a major cause of pneumonia in the late 19th century and is thus the subject of many humoral immunity studies. It causes many other types of pneumococcal infections other than pneumonia including acute sinusitis, otitis media, meningitis, bacteremia, sepsis, septic arthritis, peritonitis, cellulites, and brain abscess. It...

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...
