The isolation frequency of Arcobacter species in children with diarrhea, fowls, mammals and food of avian and marine origin was established. In all the samples it was possible to isolate Arcobacter species corresponding 201 (39.4%) to A. butzleri and 24 (4.7) to A. cryaerophilus . Both species were simultaneously isolated in 19 (3.7%) being A. butzleri the(More)
The occurrence of Campylobacter species in healthy, well-nourished and healthy, malnourished children of low socioeconomic level in Southern Chile was determined. Campylobacter carriers were significantly most frequent among malnourished (31.4%) than among well-nourished (9.9%) children. Six species were isolated from malnourished children whereas four were(More)
This study aims to assess the diversity of campylobacteria (Campylobacter and Arcobacter) in human fecal samples from patients with diarrhea (n = 140) and asymptomatic controls (n = 116) in Chile, using a combination of traditional culture and molecular methods. The culture methods detected campylobacteria in 10.7% of the patients with diarrhea and in 1.7%(More)
Acanthamoeba castellanii is a free-living amoeba widely found in environmental matrices such as soil and water. Arcobacter butzleri is an emerging potential zoonotic pathogen that can be isolated from environmental water sources, where they can establish endosymbiotic relationships with amoebas. The aim of this study was to describe the implication of(More)
The susceptibility patterns of 108 Campylobacter jejuni subsp. jejuni clinical strains, to six antimicrobial agents was determined by using the E-test and the double dilution agar methods. Using both methods, no strain was found to be resistant to ciprofloxacin, erythromycin and gentamicin, but two (1.8%) were resistant to tetracycline and all to aztreonam.(More)
We investigated the possibility of enhancing the adherence capacity of four low-adherent Arcobacter butzleri strains after serial intraperitoneal passage (i.p.) in mice. All the strains enhanced their adherence capacity after the first passage, increasing their adhesion rates after each passage. These results suggest that i.p. passage enhances the(More)
