Microbiological identification of some culturable native strains associated with the digestive tract in Panaque cochliodon

Objective. To characterize the native strains associated with the intestinal tract of the species Panaque cochliodon by microbiology. Materials and methods. Three adult specimens were used. These were captured in the Magdalena River, transported, and sacrificed under animal welfare regulations. Dissection of the intestinal tract was performed, obtaining samples for microbiological isolation, using culture media, purifying the microorganisms, and performing metabolic biochemical tests and API 20E (Biomeriux) tests for their identification. Results. Information on the microbial population structure was obtained, reporting the phylum Proteobacteria with the species Pantoea sp., Erwinia sp., Providencia stuarti, Providencia alcalifaciens, Serratia ficaria, Citrobacter koseri, and the phylum Firmicutes with the species Bacillus sphaericus, Bacillus subtilis, Bacillus thuringiensis, Bacillus mycoides, Bacillus coagulans, and Bacillus circulans. Conclusions. The predominant culturable microorganisms in P. cohliodon belong to the phylum Proteobacteria and the phylum Firmicutes.
