background: streptococcus agalactiae, also known as group b streptococcus (gbs) is a commensal organism in the urogenital tract and rectum in approximately 25% of the healthy adult female population. the bacterium is the leading cause of bacterial meningitis, pneumonia, and sepsis in human infants. materials and methods: our study was performed over a three - month period from april to june 201...

We developed a group B streptococcus (GBS) latex serotyping kit that reduces the numbers of GBS nontypeable isolates by nearly 50%. A total of 232 isolates were tested, and 203 isolates were serotyped by the GBS latex test, while the capillary precipitation test serotyped 184 isolates.

We report a case of bacterial endocarditis caused by nonhemolytic group B streptococcus (GBS) in a 67-year-old man with no predisposing risk factors. Nonhemolytic GBS strains rarely cause illness and are usually detected in perinatal infections. We believe this to be the first reported case of endocarditis caused by a nonhemolytic strain of GBS.

The sensitivity, specificity, and negative and positive predictive values for the detection of group B Streptococcus (GBS) in 206 LIM enrichment broths by the use of subculture, GBS peptide nucleic acid fluorescent in situ hybridization (PNA FISH), and GBS PCR were 96.9%, 100%, 98.6%, and 100%; 98.4%, 100%, 99.3%, and 100%; and 100%, 100%, 100%, and 100%, respectively.

This study was conducted to find out the group B streptococcus colonisation of pregnant women in Kocaeli, Turkey. A culture plus individualised high-risk-based antibiotic prophylaxis was compared with high-risk-based approach alone. The screening of women was performed via vaginal and anal cultures for group B streptococcus (GBS). The maternal GBS colonisation rate was found to be 6.5%. All col...

GBS (Group B Streptococcus) requires capsular Sia (sialic acid) for virulence and partially modifies this sugar by O-acetylation. In the present paper we describe serotype-specific patterns of GBS Sia O-acetylation that can be manipulated by genetic and biochemical means. In vitro and in vivo assays demonstrate that this subtle modification attenuates GBS Sia-mediated neutrophil suppression and...

Streptococcus agalactiae (Lancefield group B; GBS) is one of the major pathogens in fish production, especially in Nile tilapia (Oreochromis niloticus). The genomic characteristics of GBS isolated from fish must be more explored. Thus, we present here the genome of GBS S25, isolated from Nile tilapia from Brazil.

Maternal colonization with group B Streptococcus (GBS) is a risk factor for neonatal GBS disease. Whereas serotypes Ia, Ib, II, III, and V are prevalent in the United States, types VI and VIII predominate in Japan. Recently, a serotype VIII strain was detected among 114 clinical GBS isolates from a Boston, Mass., hospital.

Group B beta haemolytic streptococcus (GBS) can have protean manifestations: Septic arthritis with or without osteomyelitis is an uncommon but known complication. An early diagnosis and an adequate duration of antibiotic treatment are crucial. A case is presented of a neonate who developed septic arthritis and osteomyelitis of the right hip and proximal femur, caused by Group B beta haemolytic ...
