    This research aimed to identify the bacteria that cause respiratory problems in guinea pigs in the Latacunga canton by applying a protocol of bacterial isolation and biochemical bacterial isolation and biochemical tests. For this purpose, 53 samples from the trachea, lung, and nasal secretion were studied, executing a microbiological analysis of isolation of gram-positive bacteria, gram-negative bacteria for the gram-negative bacteria for identification, and biochemical tests were carried out. Results showed the prevalence of gram-positive and gram-negative bacteria in 21 samples corresponding to Staphylococcus spp (39.62%); Klebsiella spp eight samples (15.09%); Streptococcus spp six samples (11.32%); Proteus spp five samples (9.43%); Pasteurella spp four samples (7.54%); with a total of 3 samples Bacillus spp. Bacillus spp and E.coli spp had three samples (5.66%); finally, samples Actinomyces spp, Trueperella spp, and Citrobacter spp (1.88%). As for the presence of mono-infection bacterial infections were 18(33,96%) Staphylococcus spp; mixed infections, 14 (26,41%) Staphylococcus spp and Klebsiella spp; multiple infections, 21 (39,62%) Staphylococcus spp Proteus spp, E. coli spp. Their synergistic interaction between these pathogens can intensify the severity of infections. Prevalence of gram-positive Staphylococcus spp in a large majority (65.62%). spp with 65.62% and the gram-negative bacteria Klebsiella spp with 38.09%. within which are considered opportunistic agents Citrobacter spp Acynomices spp with 1.88%. agents that may be present in the digestive tract and which, by reducing the immune system, can penetrate the digestive; the immune system can penetrate the tissues and spread to the respiratory tract.
