Epidemiological aspects of group B streptococci of bovine and human origin

Presence of insertion sequences (IS elements) in group B streptococci of bovine origin.

BACKGROUND & OBJECTIVES Streptococcus agalactiae (group B streptococci, GBS) is one of the leading causative agents of human and animal infections. Recently it was demonstrated that integration of different IS elements could inactivate some of the GBS virulence properties. The presence of IS elements in human isolates has been studied while the bovine isolates were not investigated till now. Th...

The 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...

Human 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.
