چکیده
Comparative results obtained in isolating salmonellae from faeces by the use of tetrathionate broth, MS, and MM enrichment medium are given. The best results were obtained by tetrathionate broth prepared from infusion broth. The MS as well as the MM medium increased the total number of positive results.

Rapid isolation of salmonellae from faeces.
Factors and techniques leading to the more rapid isolation of salmonellae from faeces that are negative by direct plating were examined. The aim was to increase the number of specimens on which positive reports might be given within 24 hours of receipt. Salmonellae were isolated from 279 of the specimens studied. Brilliant green MacConkey agar was found to be the most satisfactory solid selecti...
متن کاملNovobiocin-tetrathionate broth: a medium of improved selectivity for the isolation of Salmonellae from faeces.
The selective cultivation of bacteria by incorporating chemicals in the media depends on supplying a substance which either stimulates the growth of the species to be isolated or inhibits unwanted species. Tetrathionate is a good selector of Salmonellae in faeces culture, and is believed to act in both ways. Tetrathionate reducers, such as Salmonellae, flourish in broth containing it, whereas a...

Seven-thousand-and-thirty-six specimens of faeces were examined for Salmonellae using three enrichment culture media in parallel.Rappaport's magnesium chloride malachite green broth medium proved superior to selenite F and tetrathionate broths in the recovery of a wide variety of Salmonella serotypes. However, it was inferior to selenite broth in the recovery of Salmonella typhi.A higher recove...
متن کاملEfficient isolation of campylobacters from stools: what are we missing?
The past three decades have witnessed the rise of campylobacter enteritis in humans from virtual obscurity to notoriety, with present isolation rates superseding those of other enteric pathogens such as Salmonella spp. and Shigella spp. in most developed countries. Unlike the salmonellae and other enteric pathogens, most (∼ 99%) clinical reports concerning campylobacter are sporadic, and campyl...

AIMS To compare the performance of four media, singly and in combination, as direct plating media for the isolation of Salmonella enterica from human faeces. METHODS Two thousand four hundred and nine routine, faecal samples received by four laboratories were inoculated on to xylose lysine desoxycholate (XLD), desoxycholate citrate (DCA), mannitol lysine crystal violet brilliant green (MLCB),...
