The bacterium Streptococcus agalactiae is an etiologic agent in the pathogenesis of endocarditis in humans. FbsA, a fibrinogen-binding protein produced by this pathogen, is considered an important virulence factor. In the present study we provide evidence that S agalactiae clinical isolates bearing FbsA attach to fibrinogen and elicit a fibrinogen-dependent aggregation of platelets. Mutants of ...

The aim of this work was to study and compare macrolide resistance patterns among Streptococcus pneumoniae, Streptococcus agalactiae and Streptococcus pyogenes, to describe the phenotypes of macrolide-lincosamide resistance and to further investigate associations between macrolide resistance and social clustering. Susceptibility data were obtained from 4 clinical microbiology laboratories in Ba...

Streptococcus agalactiae is an important human and animal pathogen. To better understand the genetic features and evolution of S. agalactiae, multiple factors influencing synonymous codon usage patterns in S. agalactiae were analyzed in this study. A- and U-ending rich codons were used in S. agalactiae function genes through the overall codon usage analysis, indicating that Adenine (A)/Thymine ...

background and aims: the aim of this study was to determine the virulence and antibiotic resistance properties of streptococcus agalactiae (s. agalactiae) and streptococcus uberis (s. uberis) isolated from the ruminant’s sub-clinical mastitic milk in iran. materials and methods: positive samples in the cmt test were cultured and s. agalactiae and s. uberis have been identified using biochemical...

The camel is the most valuable livestock species in arid and semi-arid regions in the Greater Horn of Africa. Streptococcus agalactiae and Staphylococcus aureus are important pathogens for a wide range of hosts including camels, cattle and humans. Streptococcus agalactiae has been reported to cause infections of the skin, the respiratory tract, the mammary gland and the vaginal tract in camels....

Streptococcus agalactiae (group B streptococcus [GBS]) is a Gram-positive bacterium that was first recognized as a causative agent of bovine mastitis. S. agalactiae has subsequently emerged as a significant cause of human diseases. Here, we report the draft genome sequence of S. agalactiae PR06, which was isolated from a septicemic patient in a local hospital in Malaysia.

Streptococcus agalactiae and Candida albicans often co-colonize the female genital tract, and under certain conditions induce mucosal inflammation. The role of the interaction between the two organisms in candidal vaginitis is not known. In this study, we found that co-infection with S. agalactiae significantly attenuated the hyphal development of C. albicans, and that EFG1-Hwp1 signal pathway ...

Heme is essential for several cellular key functions but is also toxic. Whereas most bacterial pathogens utilize heme as a metabolic cofactor and iron source, the impact of host heme during bacterial infection remains elusive. The opportunist pathogen Streptococcus agalactiae does not synthesize heme but still uses it to activate a respiration metabolism. Concomitantly, heme toxicity is mainly ...

The isolation and characterization of two bacterial species, Streptococcus agalactiae and Lactococcus garvieae, previously unreported in wild marine mammals are described from a freshly dead bottlenose dolphin, Tursiops truncatus, from Kuwait Bay, Kuwait, in September 2001. Conventional and rapid identification systems were used to determine that isolates from muscle and kidney were S. agalacti...

Streptococcus agalactiae is the leading cause of bacterial sepsis and meningitis in neonates and also the causative agent of different serious infections in immunocompromised adults. The wide range of diseases that are caused by S. agalactiae suggests regulatory mechanisms that control the formation of specific virulence factors in these bacteria. The present study describes a gene from S. agal...
