Product Code TM 2082

  • Description

    Selective inhibitory effects of selenite were first demonstrated by Klett. Guth used it to isolate Salmonella Typhi. Leifson studied selenite and formulated a medium using selenite. Fluid Selenite Cystine Medium is a modification of Leifsons formula with added cystine. The formulation corresponds to that recommended by AOAC for the detection of Salmonella in foodstuff, particularly egg products. It is also recommended by APHA and USP.
    Selenite Cystine Broth is useful for detecting Salmonella in the non-acute stages of illness when organisms occur in the faeces in low numbers and for epidemiological studies to enhance the detection of low numbers of organisms from asymptomatic or convalescent patients. Salmonella are also injured during various food processing procedures, including exposure to low temperatures, sub-marginal heat, drying, radiation, preservatives or sanitizers. Recovery of Salmonella involves pre- enrichment, selective enrichment and selective plating since Salmonella may be present in low numbers in food sample in an injured condition.
    Fluid Selenite Cystine Medium is used as selective enrichment medium for the cultivation of Salmonella species. This medium is formulated to allow the proliferation of Salmonella while inhibiting the growth of competing non-Salmonella organisms.
