REVIEW
Baldeep Khare, Sthanam Vl Narayana
Successful adherence, colonization, and survival of Gram-positive bacteria require surface proteins, and multi-protein assemblies called pili. These surface appendages are attractive pharmacotherapeutic targets and understanding their assembly mechanisms is essential for identifying a new class of 'anti-infectives' that do not elicit microbial resistance. Molecular details of the Gram-negative pilus assembly are available in-depth, but the Gram-positive pilus biogenesis is still an emerging field and investigations continue to reveal novel insights into this process...

BACKGROUND: Worldwide, indigenous populations appear to be at increased risk for invasive group A streptococcal (iGAS) infections. Although there is empirical evidence that the burden of iGAS disease is significant among remote First Nations communities in Northwestern Ontario, Canada, the epidemiology of iGAS infections in the area remains poorly characterized. METHODS: Individuals that met case definition for iGAS disease and whose laboratory specimens were processed by Meno Ya Win Health Centre in Sioux Lookout, Canada or who were reported to Thunder Bay District Health Unit, Canada were identified for the period 2009 to 2014...

Objectives: Among viridans group streptococcal infective endocarditis (IE), the Streptococcus mitis group is the most common aetiological organism. Treatment of IE caused by the S. mitis group is challenging due to the high frequency of β-lactam resistance, drug allergy and intolerability of mainstay antimicrobial agents such as vancomycin or gentamicin. Daptomycin has been suggested as an alternative therapeutic option in these scenarios based on its excellent susceptibility profile against S...

The TCR Vβ repertoire from patients with recurrent tonsillitis and/or tonsillar hyperplasia was examined to determine whether the TCR Vβ composition is suggestive of local superantigen activity and if so, whether it is associated with the presence of superantigen producing bacteria. Tonsil specimens were cultured aerobically to allow identification and isolation of the bacterial pathogens Staphylococcus aureus and Group A Streptococcus. TCR Vβ subset analysis of tonsil leucocytes was performed by flow cytometry...

PURPOSE: Current evidence is inconclusive regarding the intrapartum administration of chemoprophylaxis, merely based on the presence of group B streptococcal (GBS) bacteriuria of any colony count, in the prevention of early-onset neonatal GBS infection. The aim of this study was to assess whether GBS bacteriuria is a risk factor for intrapartum colonization (IPC) regardless of urinary concentration or the results of late third-trimester rectovaginal screening cultures (RVSCs). METHODOLOGY: Six hundred and eight pregnant women, with urine specimens cultured between May 2011 and May 2013, were enrolled in this prospective cohort study...

Streptococcus pyogenes group A Streptococcus (GAS) is the most common cause of bacterial throat infections, and can cause mild to severe skin and soft tissue infections, including impetigo, erysipelas, necrotizing fasciitis, as well as systemic and fatal infections including septicaemia and meningitis. Estimated annual incidence for invasive group A streptococcal infection (iGAS) in industrialised countries is approximately three per 100,000 per year. Typing is currently used in England and Wales to monitor bacterial strains of S...

Empiric initial antibiotic therapy of bacterial infections is based primarily upon the susceptibility of the most common causative pathogens. The purpose of this study was to provide susceptibility data on six bacterial species known to cause ear, nose and throat (ENT) infections. A total of 1066 isolates collected during a nationwide laboratory-based surveillance study were analysed. All Streptococcus pyogenes isolates were penicillin (PEN)-susceptible, indicating that natural penicillins can still be recommended as the first-line treatment for group A streptococcal tonsillopharyngitis...

BACKGROUND: Successful commensal bacteria have evolved to maintain colonization in challenging environments. The oral viridans streptococci are pioneer colonizers of dental plaque biofilm. Some of these bacteria have adapted to life in the oral cavity by binding salivary α-amylase, which hydrolyzes dietary starch, thus providing a source of nutrition. Oral streptococcal species bind α-amylase by expressing a variety of amylase-binding proteins (ABPs). Here we determine the genotypic basis of amylase binding where proteins of diverse size and function share a common phenotype...

Streptococcus intermedius, a member of the Streptococcal anginosus group of alpha-hemolytic streptococci, remains a notable infectious agent causing necrotizing pneumonia and abscesses. We report a case of a young male with pulmonary nodules found to have Streptococcus intermedius and no other underlying hepatic or dental history who was treated with ceftriaxone and avoided surgical intervention. A review of the literature reveals cases that are typically treated with a combined surgical and medical approach...

Streptococcus pyogenes (GAS) is one of the major human pathogenic bacteria that cause a wide range of diseases. Currently, increased incidence of streptococcal invasive infections is observed worldwide. In this study, we focused on the prevalence of genes encoding superantigens and type M proteins in the population of GAS strains from invasive versus non-invasive infections. We tested 253 GAS strains: 48 strains from patients with invasive infections (18 from wound/deep skin localization, 30 from women in labour) and 205 strains from non-invasive forms (147 from common infections of the upper respiratory, 49 from the vagina of females with genital tract infections and 9 from non-invasive wound and superficial skin infections)...
