Necrotizing fasciitis is a fulminant infection that affects the deep and superficial fascia while initially sparing the overlying skin and underlying muscle. The involvement of the cervical compartment is associated with a high morbidity and mortality rate. Immunocompromised patients are prone to this infection. We present a case of a 80 year-old diabetic woman suffering from streptococcal cerv...

Most infections by group B streptococcus of the Lancefield classification (Streptococcus agalactiae), were reported in pregnant women or during the puerperal period, as well as in neonates. During the past three decades there have been reports of increasingly invasive infections in adults unrelated to pregnancy, although arthritis and osteomyelitis are still very rare. In this article, we descr...

Streptococcal species are Gram-positive bacteria involved in severe and invasive diseases in humans and animals. Although, this group includes different pathogenic species involved in life-threatening infections for humans, it also includes beneficial species, such as Streptococcus thermophilus, which is used in yogurt production. In bacteria virulence factors are controlled by various regulato...

The objectives of this study were to estimate the herd prevalence of major mastitis pathogens in bulk tank milk (BTM) in China dairy herds, to determine the relationship between the presence of mastitis pathogens and bulk tank milk somatic cell counts (BTSCC), and to investigate the impact of different dairy cattle farming modes and region on bacterial species. BTM samples collected from 894 da...

Streptococcus agalactiae infection causes high mortality in cardiovascular disease (CVD) patients, especially in case of setting prosthetic valve during cardiac surgery. However, the pathogenesis mechanism of S. agalactiae associate with CVD has not been well studied. Here, we have demonstrated the pathogenicity of S. agalactiae in rat cardiomyocytes (H9C2). Interestingly, both live and dead ce...

group b streptococcus (gbs) is a major cause of severe systemic and local infections in newborns. this study was performed to evaluate the presence of gbs in pregnant women and their newborns in tabriz, iran. vaginal specimens were collected from 965 women who were candidate for vaginal delivery for bacteriological study of group b streptococci. several samples from various sites of the newborn...

The localization and accessibility of the group B streptococcus (GBS) surface immunogenic protein (Sip) at the surface of intact GBS cells were studied by flow cytometric assay and immunogold electron microscopy. Antibodies present in pooled sera collected from mice after immunization with purified recombinant Sip efficiently recognized native Sip at the surfaces of the different GBS strains te...

Title: Genotyping of Streptococcus agalactiae (group B streptococci) isolated from vaginal and rectal swabs of women at 35-37 weeks of pregnancy
