TAMBORINI, Ana L et al. Campylobacter spp.: prevalence and pheno-genotypic characterization of isolates recovered from patients suffering from diarrhea and their pets in La Pampa Province, Argentina. Rev. argent. microbiol. [online]. 2012, vol.44, n.4, pp.266-271. ISSN 0325-7541.

The prevalence of Campylobacter spp. was investigated in 327 patients suffering from diarrhea and in 36 animals (dogs, cats and chickens) owned by the patients that presented infection by Campylobacter in Santa Rosa, La Pampa, Argentina. Campylobacter spp. was isolated in 50/327 patients and in 12/36 animals, being Campylobacter jejuni the most common species. Resistance to ciprofoxacin (65 %) and tetracycline (32 %) was found among 35 isolates of human origin studied. Seven genetic subtypes were observed among 13 C. jejuni isolates by pulsed feld gel electrophoresis. Two subtypes grouped isolates belonging to patients and their respective dogs whereas another subtype grouped one isolate of human origin and two isolates from the patient´s chickens. The results of this investigation highlight the need to strengthen surveillance of Campylobacter spp. not only in poultry, which is recognized as the main reservoir, but also in pets, which were shown to be asymptomatic carriers of the pathogen.
