Comparison of culture methods for isolation of salmonella in yak fecal samples.


ABSTRACT: To compare the effectiveness of culture methods for identifying yak Salmonella, three selective enrichment broths (SC, TTB, MSRV) and three media (SS, XLD, CAS) for detecting Salmonella were evaluated in this study. The results showed that TTB broth was better than SC broths and MSRV broths, and SS medium has the highest isolation rate, significantly higher than those of CAS and XLD media (P < 0.05). It is worth noticing that there was no overlapping of the positive results given by TTB, SC and MSRV broths. In addition, all of the yak Salmonella isolates were detected positive by the five reported PCR assays, targeting the invA, srfC, invE, stn and 16S-23S rRNA genes. The combination of TTB and MSRV broths and SS and CAS media (or XLD) recommended in this study was relatively efficient in recovering Salmonella from yak feces, and the five PCR assays can be successfully used to identify yak Salmonella.
