“…The cultures included 48 isolates from canine origin, seven isolates from feline origin and for comparative purposes group B streptococci isolated from bovines (n = 10) and humans (n = 9). The latter, obtained from the institute's strain collection, were described previously [13], the canine and feline isolates were obtained from routine diagnostics from two independent diagnostic laboratories (laboratory 1, n = 33; laboratory 2, n = 22).…”

“…Corresponding to Granlund et al [43] and Rolland et al [44] and to previous results [24,29] the lack of activity of the enzyme hyaluronidase and a hylB amplicon of 4.6 kb inactivated by IS1548 of the group B streptococci of the present study appeared to be related to the occurrence of polysaccharide antigen III. However, type antigen III is a common polysaccharide antigen for human group B streptococci, less pronounced among bovine strains [13].…”

In the present study streptococci of serological group B isolated from canines (n = 48) and felines (n = 7) were comparatively investigated with group B streptococci from humans and bovines for cultural, biochemical and serological properties for antibiotic resistancies and by molecular analysis. An identification was performed with group B-specific antiserum, biochemical reactions, by PCR amplification and subsequent endonuclease digestion of the 16S rRNA gene and by amplification of species-specific parts of the 16S rDNA the 16S^23S rDNA intergenic spacer region and the CAMP factor gene cfb. Phenotypic similarities of group B streptococci of canine and feline origin with group B streptococci from humans and differences to group B streptococci of bovine origin could be observed in lactose fermentation, serotype patterns, pigmentation, growth properties of the bacteria in fluid medium and soft agar, hemagglutination reactions and in minocycline and tetracycline resistance. A negative hyaluronidase plate test, a hylB amplicon with a size of 4.6 kb and an insertion sequence 1548 could be observed among canine, feline and human group B streptococci of serotype III. The remaining hyaluronidase positive strains, also including all isolates of bovine origin, had a hylB gene with a size of 3.3 kb. Further genotypic differences could be observed in the occurrence of the genes lmb and scpB which appeared generally among canine, feline and human group B streptococci, but less pronounced among bovine isolates of this species. According to the presented data group B streptococci of canine and feline origin seemed to be more related to human than to bovine isolates of this species possibly indicating some epidemiological relation. ß

“…The monospecificity of the antisera was achieved by absorption of the antisera with cross-reacting antigens. 15 In addition, antisera against group B streptococcal reference strain JM9 (provisional type VIII) was kindly provided by J. Jelinkova (Streptococcus Reference Laboratory, Prague, Czech Republic) and antisera against the purified protein antigens Rib, ca and cp were kindly provided by M. Stilhammar-Carlemalm and G . Lindahl (Institute for Medical Microbiology, Lund, Sweden).…”

“…A direct transmission of group B streptococci between cattle and humans remains uncommon [8,9]. Cultural, biochemical, serological and various other properties described by numerous authors [10–13] allowed a clear differentiation of bovine and human isolates of this species. According to Devriese[6] S. agalactiae isolated from bovine mastitis play no role as zoonotic agent and bacteria of both origins could be divided into a bovine and a human ecovar.…”
