The pathogenic equine streptococci.
Streptococci pathogenic for the horse include S. equi (S. equi subsp. equi), S. zooepidemicus (S. equi subsp. zooepidemicus), S. dysgalactiae subsp. equisimilis and S. pneumoniae capsule Type III. S. equi is a clonal descendent or biovar of an ancestral S. zooepidemicus strain with which it shares greater than 98% DNA homology and therefore expresses many of the same proteins and virulence fact...

متن کاملInterspecies Communication among Commensal and Pathogenic Streptococci
UNLABELLED Quorum sensing (QS) regulates diverse and coordinated behaviors in bacteria, including the production of virulence factors, biofilm formation, sporulation, and competence development. It is now established that some streptococci utilize Rgg-type proteins in concert with short hydrophobic peptides (SHPs) to mediate QS, and sequence analysis reveals that several streptococcal species c...
متن کاملEnterococcus faecalis and pathogenic streptococci inactivate daptomycin by releasing phospholipids
Daptomycin is a lipopeptide antibiotic with activity against Gram-positive bacteria. We showed previously that Staphylococcus aureus can survive daptomycin exposure by releasing membrane phospholipids that inactivate the antibiotic. To determine whether other pathogens possess this defence mechanism, phospholipid release and daptomycin activity were measured after incubation of Staphylococcus e...
متن کاملThe Serological Differentiation of Pathogenic and Non-pathogenic Strains of Hemolytic Streptococci from Parturient Women
1. The majority of strains of hemolytic streptococci from puerperal infections of the uterus were identified serologically as members of the Group A described by Lancefield. 2. The majority of strains isolated from the birth canal of women whose puerperium was afebrile were not members of Group A. 3. The existence of two new serological groups of hemolytic streptococci, Groups F and G, is descr...
