Abstract: Didelphis virginiana is the only Mexican marsupial, in spite of to be a wild animal, it has been adapted to live near to human. We proceeded to evaluate the proportion of drug-resistant microorganisms isolated from D. virginiana, the study was done in the Mexican State of Hidalgo; were captured six adult animals, it were anesthetized. Samples were taken from the oral cavity, pharynx exudates, otic, optical and feces of all of them. The bacterial isolated were identified biochemically and evaluated by Disk Diffusion Susceptibility Testing. Were isolated Gram-negative bacteria, like Escherichia coli, Proteus mirabilis, Citrobacter freundii, Edwardsiella sp., Klebsiella pneumoniae, Pseudomonas aeruginosa, Mannheimia haemolytica and Gram-positive like Staphylococcus aureus coagulase-negative, Staphylococcus epidermidis, Streptococcus faecalis, Corynebacterium sp. and Bacillus subtilis. The results showed different levels of antibiotic resistance of bacteria isolated from wild opossums; multidrug-resistance was found in some of the strains in or at least one of them. D. virginiana could be a reservoir for a variety of microorganisms that have antimicrobial resistance and transfer it to other species as domestics like wild animal.
