The Philippine Native Swine has been widely accepted as a more robust and more disease-resistant swine breed than the white crossbreeds or hybrid. The microbiota of an animal's intestinal tract has long been shown to play significant functions in the overall health and productivity of swine. However, there is no known study on the microbial diversity in the gut of the Philippine native swine. In this study, the microbial succession in the ileum of Philippine native swine at one-, two-, three-, and four-week- old was determined by 16S rRNA gene analysis using the paired-end Illumina HiSeq platform. A clear succession pattern of microbial colonization was observed where the phyla Chlamydiae and Proteobacteria were predominant in one-week-old swine while Firmicutes dramatically increased as the swine aged. The most dominant bacterial genera at every swine age were potentially pathogenic to both humans and animals. Phenotypic and genotopic analyses of 58 weaning and market age swine from various municipalities in Quezon province revealed the occurrence of bacteria that could cause food poisoning. The shiga toxin-producing Eschirichia coli (STEC) and Salmonella were detected at 91% and 26% of the native swine, respectively.
