Isolation of Salmonellae from Food Samples
TAYLOR, WELTON I. (Swift and Company, Chicago), AND JOHN H. SILLIKER. Isolation of salmonellae from food samples. IV. Comparison of methods of enrichment. Appl. Microbiol. 9:484-486. 1961. A comparison of various methods of enhancing frequency of Salmonella isolations revealed that inoculation of a second enrichment broth, with culture from the first, wi-as no improvement over the single direct...
متن کاملRapid 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 کاملIsolation of Salmonellae from Food Samples. Vi. Comparison of Methods for the Isolation of Salmonella from Egg Products.
THE RECOVERY OF SALMONELLAE FROM EGG PRODUCTS WAS STUDIED, BY USE OF THREE DIFFERENT ENRICHMENT PROCEDURES: (i) selenite broth, (ii) selenite broth containing 10% sterile feces, and (iii) the lactose pre-enrichment procedure. Brilliant Green Agar was used throughout as the recovery medium. Although the lactose pre-enrichment methodology promoted Salmonella recovery from samples containing small...
متن کاملComparison of CHROMagar Salmonella medium and hektoen enteric agar for isolation of salmonellae from stool samples.
CHROMagar Salmonella (CAS), a new chromogenic medium, was retrospectively compared to Hektoen enteric agar (HEA) with 501 Salmonella stock isolates and was then prospectively compared to HEA for the detection and presumptive identification of Salmonella spp. with 508 stool samples before and after enrichment. All stock cultures (100%), including cultures of H2S-negative isolates, yielded typica...
متن کاملIsolation of Salmonellae from food samples. IV. Comparison of methods of enrichment.
A comparison of various methods of enhancing frequency of Salmonella isolations revealed that inoculation of a second enrichment broth, with culture from the first, was no improvement over the single direct enrichment method. It was inferior to centrifugation. Selenite was observed to produce more positive isolations at 48 hr than at 24. No change occurred in tetrathionate. Reconstitution of dr...
