FLUID SELENITE CYSTINE MEDIUM (DOUBLE PACK) (as per IP) (DOUBLE PACK) (PART – I)

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. Fluid Selenite Cystine Medium is a modification of Leifsons formula with added cystine by North and Bartram. It is employed for the detection of Salmonellae in foodstuff, particularly egg products. It is included by APHA, IP. Selenite Cystine Broth is useful for detecting Salmonella in the non-acute stages of illness when organisms occur in low numbers in test samples and for epidemiological studies to enhance the detection of low numbers of organisms from asymptomatic or convalescent patients.
