Our work on the genomics of B. fragilis led to the identification of the first homologue of eukaryotic ubiquitin in a bacterium. The protein (BfUbb) shares 63% identity with human ubiquitin and is capable of inhibiting ubiquitylation in vitro. BfUbb also has novel antimicrobial properties against a number of B. fragilis strains.Capsular polysaccharides represent the outermost surface of encapsulated bacteria, such as Bacteroides fragilis, making these molecules the first point of contact with the immune system. Of the eight different capsular polysaccharides found on B. fragilis [ 10 ], polysaccharide A (PSA) and B (PSB) are zwitterionic, possessing both positive and …Blastocystis is a microscopic parasite that can live in your digestive tract. Researchers don't fully understand the role blastocystis plays, if any, in causing disease. Some people experiencing diarrhea, abdominal pain or other gastrointestinal problems have blastocystis organisms in their stool. Most commonly, however, blastocystis organisms ...

Aztreonam (azthreonam; SQ 26,776) is the first member of a new class of beta-lactam antibiotics, the monobactams. Aztreonam is selectively active against Gram-negative aerobic bacteria and inactive against Gram-positive bacteria. Thus, in vitro, aztreonam is inhibitory at low concentrations (MIC90 less than or equal to 1.6 mg/L) against ...B. fragilis strains NCTC 9343 (9343), 13,14 NCTC ΔPSA 9343 (ΔPSA 9343) (isogenic mutant), 49 and 86-5443-2-2 (86) 13,14 were used for experiments except as indicated.However, in the Japanese individuals these species are rare with minimal representation in a subset of subjects. While considering the genus Bacteroides, it is well established that B. uniformis, Bacteroides sp., B. ovatus, and B. fragilis are well conserved in the gut microbiome of Japanese individuals. In the fungal community, Ascomycota and ...Summary. Streptococcus agalactiae, also known as group B streptococcus, is a gram-positive, beta-hemolytic, catalase-negative, and bacitracin -resistant bacterium, which can cause several infections in humans. Most frequently, Streptococcus agalactiae causes neonatal infections like pneumonia, sepsis, meningitis, and septic arthritis.

The B. fragilis group is a member of the Bacteroidaceae family. It includes several species, with B. fragilis being the most frequent isolate. These bacteria mainly cause intra-abdominal infections and infections that originate from those florae (such as perianal abbesses and decubitus ulcers) [1,14,15].The rate of B. fragilis resistance to cefoxitin in recent years has been 6.8–33.3% in Europe, 12.6% in Canada, and 23% in Brazil [8, 38, 39].
