INCIDENCE AND CHARACTERIZATION OF SALMONELLA FROM LOCAL MILK DAIRIESG. L. BHOOSREDDY, B. J. WADI IER, AND NIRALI PATEL
Out of 50 milk samples analyzed thirty samples were found to contain Salmonella Efficacy of lactose broth as pre-enrichment medium and TT broth as enrichment medium has allowed greater isolation of Salmonellal. Efficacy of TSI and LIA compared, the results of which show that additional 24h incubation is required to give typical alkaline red slant with acidic yellow butt and darkening of the medium due to H2S production not within 24 hours as per the reports of BAM. BSA as selective plating media for isolation and halo effect characteristic of Salmonella species required 24h without an additional 24h incubation. XLD and HE agar streaked with growth from presumed positive TSI slants did not give characteristic colonies of Salmonella and allowed fewer isolation.
