Salmonella species, inhibition

Media containing tetrathionate, which is also toxic to E. coli, is used in a similar manner to isolate Salmonella species. This medium does allow the growth of Proteus, which may be inhibited by the addition of the antibiotic novobiocin, thus rendering the medium specific for Salmonella. Tetrathionite broth may be used for the enrichment of contaminated material containing Salmonella. 

In contrast to the results with BP, incubation of BP-7,8-dihydrodiol with ram seminal vesicle microsomes and arachidonate generates a species that is strongly mutagenic to Salmonella strains TA98 and TA100 (Figure 3) (22). Formation of the mutagen is inhibited by... 

Much of the work involving reduction of pathogens by LAB has been done in poultry and has focused on the reduction of Salmonella, but some work has also been done on inhibition of Campylobacter. The most commonly studied defined organisms are strains of Lactobacillus, especially L. acidophilus. However, the results obtained from the studies to demonstrate the efficacy of DFMs have been controversial. Additionally, work done on undefined cultures also indicates that pathogen reductions can occur using species other than lactobacilli.
