Bacteroides - MicrobeWiki Bacteroides thetaiotaomicron have been shown to bind to polysaccharides with their outer membrane receptor system (the outer membrane can be seen in the picture to the right) before pulling the polysaccharides into the periplasm for monosaccharide degradation. The Bacteroides definition has specific criteria, some of which are as follows: obligately anaerobic, gram-negative, saccharolytic, contain enzymes of the hexose monophosphate shunt-pentose phosphate pathway, have a DNA-base composition of about 40-48% G-C, and membranes contain a mixture of long-chain fatty acids, mainly straight chain saturated, anteiso-methyl, and iso-methyl branched acids. When Bacteroides escape the gut, they are responsible for many types of infections and abscesses that can occur all over the body including the central nervous system, the head, the neck, the chest, the abdomen, the pelvis, the skin, and the soft tissues. microbewiki.kenyon.edu /index.php/Bacteroides   (1228 words)

eMedicine - Bacteroides Infection : Article by Itzhak Brook, MD, MSc Bacteroides species are anaerobic bacteria that are predominant components of the bacterial florae of mucous membranes and, therefore, are a common cause of endogenous infections. Bacteroides infections can occur in all body sites, including the CNS, the head, the neck, the chest, the abdomen, the pelvis, the skin, and the soft tissues. Treatment is complicated by 3 factors: slow growth, increasingly encountered resistance to antimicrobials, and the polymicrobial nature of the infection. www.emedicine.com /med/topic2945.htm   (5265 words)

Neonatal and maternal postpartum bacteroides bacteremia OBJECTIVE: A unique case of Bacteroides fragilis bacteremia in a mother and her infant prompted a review of these infections in neonates and postpartum mothers during a five-year period at two institutions in Winnipeg, Manitoba. Postpartum fever and emergency caesarean section were often noted with maternal postpartum bacteroides bacteremia, while fetal distress, low Apgar scores and respiratory distress were frequent in neonatal bacteremia. Neonatal bacteroides bacteremia may not be readily suspected on clinical grounds, so clinicians should ensure that the laboratory procedures routinely used to evaluate neonatal bacteremia at their institutions reliably detect these organisms. www.pulsus.com /Infdis/10_05/zake_ed.htm   (583 words)

Bacteroides fragilis Bacteroides is the most frequent anaerobic pathogen in man (80% of anaerobic infections). Bacteroides plays a key role in enterohepatic bile acid recirculation, and bile acid biotransformation. Bacteroides also probably compete with pathogenic micro-organisms for colonic resources - diminishing the food supply and receptor sites for agents such as Salmonellae and Shigellae, and making the environment unfavourable by deconjugating bile salts and changing the pH. www.anaesthetist.com /icu/infect/bacteria/anaerobe/bfrag.htm   (930 words)
