| Sumario: | Campylobacter antibiotic resistance has increased in a variable geographic pattern, but there is limited data from Argentina. Our aim was to determine the prevalence of campylobacteriosis in our population and their susceptibility pattern. The feces of 1 321 patients were analysed during a period of 2 years (2006-2008) in Clinica Privada Universitaria Reina Fabiola, Córdoba, Argentina. Campylobacter spp. was isolated from 258 patients (19.5%), Salmonella spp. was found in 74(5.6%), Shigella spp. in 26 (2%) and Escherichia coli O157H7 5 in (0.4%). Positive samples were 27% (363). The incidence among male subjects was consistently higher than that among female subjects in all age groups. A bimodal pattern was seen in the incidence of Campylobacter infection by age group, 2 age-peaks occurred: the first at 1-4 years of age, and a second surge occurred during young adulthood, at 20-29 years of age. We assessed the sensitivity of 93 strains. The prevalence of ciprofloxacin-resistant Campylobacter was 74% (69 of 93), erythromycin resistance was 2% (3 of 93), tetracycline resistance was 36% (34 of 93). None of the 93 Campylobacter isolates tested was chloramphenicol or furazolidone resistant. The high resistance of this organism to quinolones should lead us to reconsider the use of fluoroquinolones in the initial empiric treatment of invasive diarrhea. |
