Identificación de los agentes etiológicos en lesiones y ganglios post mortem en la granja cuy andino de la ciudad de Latacunga.

This project aims to identify the etiological agent in post-mortem lesions and ganglions in the Andean guinea pig farm in the city of Latacunga from bacterial isolation and biochemical tests. For which, 36 samples from lymph nodes, liver, leg abscess, and intestine were studied, performing a microbiological analysis of isolation using the manual of the Spanish Society of infectious diseases (AOAC), ISO/TS 11133-1, ISO/TS 11133-2 performing a protocol for Gram-positive bacteria and Gram-negative bacteria, for confirmation by traditional biochemical tests by means of TSI, SIM, Catalase, Oxidase. The results showed 11% (4/36) of mixed infection and 89% (32/36) of mono-infection, 21% of Staphylococcus spp, 14% of Streptococcus spp, 7% of Bacillus spp, 7% Erysipelothrix spp, 7% Trueperella spp, 50% Salmonella spp, 14% E. coli spp, in lymph nodes 37% Staphylococcus spp, 11% Streptococcus spp, 11% Bacillus spp, 11% Trueperella spp, 39% Salmonella spp, 11% E. coli spp, in leg abscess Erysipelothrix spp was found as the only agent and in intestine E. coli spp was found as the only agent. Resulting from the total of 36 samples (100%) in the liver 39% where 25% is affected by Gram-negative and 14% by Gram-positive, in the lymph node 53% of which 22% corresponds to Gram-negative and 31% to Gram-positive, in the intestine 2% where it is only affected by Gram-negative and in leg abscess 3% which is only affected by Gram-positive. In conclusion, lymphadenitis is caused by various etiological agents, because they are opportunistic pathogens and enter through a primary infection, so controls and biosecurity measures should be carried out to control the disease.
