Extracellular virulence factors of group B Streptococci.
Group B Streptococcus (GBS) is the leading cause of severe bacterial infections in human newborn infants. Advances in streptococcal molecular genetics and refinement of in vitro and in vivo model systems of GBS disease have led to the discovery and characterization of several extracellular virulence factors elaborated by this pathogen. This review summarizes our current understanding of GBS ext...
متن کاملThe role of b-hemolytic streptococci group B and anearobic infections in preterm premature rupture of membrane
preterm premature rupture of membrane(PPROM)is one of the serious problems during pregnancy.the aim of this study was to determine the probable relation between group B streptococal and anaerobic infections and PPROM.for this porpust 100 pregnant women with preterm rupture of membrane were selected.in the case group the prevalence of B-hemolytic streptococcal and anaerobic microorganisms was de...
متن کاملHuman Group A Streptococci Virulence Genes in Bovine Group C Streptococci
Phage-encoded virulence genes of group A streptococci were detected in 10 (55.6%) of 18 isolates of group C streptococci that had caused bovine mastitis. Bovine isolates carried other genetic determinants, such as composite transposon Tn1207.3/F10394.4 (100%) and antimicrobial drug resistance genes erm(B)/erm(A) (22.2%), linB (16.6%), and tet(M)/tet(O) (66.7%), located on mobile elements.
متن کاملGroup B streptococci--gastrointestinal organisms?
Matched perianal swabs, rectal swabs, and faecal samples from a group of male homosexual patients attending a clinic for sexually transmitted disease were examined for the presence of group B streptococci (GBS). GBS recovery rates were as follows: perianal skin 31/115 (27%), rectal mucosa 18/72 (25%) and faeces 7/115 (6%). The recovery of GBS from faeces was similar to that obtained from faecal...
متن کاملGroup B streptococci in neonatal deaths.
Clinical microbiologists are reminded to look for group B streptococci in neonatal infants. We report four deaths, one with meningitis, occurring among 14 such infected newborn infants at our institution; of the nursing staff, 31% were also carriers of group B streptococci.
