Occurrence of Campylobacter jejuni and Campylobacter coli biotypes and antimicrobial susceptibility in healthy dogs in Southern Chile

Fernández, HeribertoOval, Andrés

Background: The thermotolerant species of Campylobacter, mainly C. jejuni and C. coli, are as important agents of human gastroenteritis worldwide, being a serious public health problem. They are widely distributed in the environment and the animal kingdom having as reservoirs a wide variety of animals, including dogs, which in turn can act as a source of infection for humans. The Campylobacter isolation rates found in dogs are heterogeneous with few available data in Latin American countries. However Campylobacter diarrhea in humans is a self-limited clinical process being antimicrobial treatment not always necessary, it is necessary to know their antimicrobial susceptibility/resistance pro- fi les in clinical and reservoirs isolates, especially in C. jejuni and C. coli strains isolated from animals close to man as dogs are. The aims of this work were to determine the isolation frequency of C. jejuni and C. coli and their biotypes in healthy dogs and the susceptibility/resistance profiles of the isolated strains to six antimicrobial drugs. Materials, Methods & Results: Fecal samples from 141 healthy dogs were obtained, seeded into the TEC transport medium. In the laboratory, each sample was plated out on modified Skirrow medium and incubated at 42C for 48 h under microaerobic conditions. The isolated strains were identified to species and biotype levels through their pheno
