Hello, I am working udder healht microbilogy lab for dairy farm, and recently i foun some streptococcal collony, I suspect that it was Streptococcus agalactiae, since there was an outbrake a year a go, the camp was negative, but when i tested it with streptococcal grouping kit (oxoid) for group B antigent was positive. Is it possible that Streptococcus agalactiae ressults negative in Camp test but possitive in Lancefield grouping for B antigen?
thx be4
