Selective Medium for Enumeration of Tannin-Protein Complex-Degrading Streptococcus spp. in Feces of Koalas.
A selective agar plate medium (tannin-treated brain heart infusion agar supplemented with colistin-oxolinic acid) was developed to enumerate tannin-protein complex-degrading Streptococcus bovis in the feces of koalas. This medium was successfully used to enumerate strains from fecal samples but failed to enumerate those from pure cultures.
