Detection and enumeration of Salmonella sp. In llama meat (Llama glama) using qPCR

Abstract

This research proposes a methodology to detect and quantify in real time the presence of Salmonella sp. in llama meat (Llama glama) using qPCR, the method was validated through the plate count. The method consisted of detecting the presence or absence of Salmonella sp. in llama meat samples, the positive results were identified by the Rapid ONE accelerated biochemical system, finally the identification results were confirmed by real-time PCR, using a forward and reverse primer of the invA gene, as well as a fluorescent probe anchored to a fragment of the invA gene. Finally, 17 samples of llama meat were quantified, resulting in 53.13% of the samples being contaminated by Salmonella sp.
