Comparison of Two Pre-Enrichment Broths for Recovering Listeria monocytogenes from Various Foods
نویسندگان
چکیده
The purpose of the present study was to compare the abilities of University of Vermont Broth (UVM) and 0.1% (w/v) peptone water for recovering Listeria monocytogenes from various foods. A total of 210 food samples (raw fish-100, mutton-60, paneer-50) was taken and pre-enrichment was carried out in UVM broth and 0.1% (w/v) peptone water. A total of five isolates were recovered, three from mutton and two from fish. However, no isolate of L. monocytogenes was recovered from paneer samples. The UVM broth detected all the five isolates, while as 0.1% (w/v) peptone water detected only three isolates showing a higher efficacy of UVM broth for isolation of L. monocytogenes as compared to 0.1% (w/v) peptone water.

Listeria monocytogenes is a species of foodborne pathogen often related to foods, such as poultry, ready-to-eat products, fruits, and vegetables. The culture method is a standard procedure for the detection of bacteria in food products. The real-time quantitative PCR (qPCR) technique can be used for the quantification of foodborne pathogens. The current research was aimed to assess...

The detection of Listeria monocytogenes from food is currently carried out using a double enrichment. For the ISO methodology, this double enrichment is performed using half-Fraser and Fraser broths, in which the overgrowth of L. innocua can occur in samples where both species are present. In this study, we analyzed the induction of phages and phage tails of Listeria spp. in these media and in ...
