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)
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)
Campylobacter insulaenigrae have been isolated from different pinnipeds but not from South American sea lion (Otaria flavescens).The aim of this work is to report the first isolation of C. insulaenigrae from South American sea lion (Otaria flavescens).The isolate, identified by its phenotypic and molecular characteristics, allow recognizing O. flavescens as(More)
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)
INTRODUCTION Helicobacter pylori is a bacteria which infects half the world population and is an important cause of gastric cancer. The eradication therapy is not always effective because resistance to antimicrobials may occur. The aim of this study was to determine the susceptibility profile of H. pylori to amoxicillin, clarithromycin and ciprofloxacin in(More)
The prevalence of Campylobacter jejuni and Campylobacter coli and their biotypes in beef and dairy cattle from the South of Chile was established. Campylobacter were statistically more prevalent among beef cattle (35.9%) than among dairy cattle (21.3%), being C. jejuni the species most frequently isolated.
The study evaluated the antibiotic resistance patterns of Helicobacter pylori strains against metronidazole and clarithromycin in a hospital in Havana, Cuba. Eighty-five percent, 22.5%, and 10% of 40 H. pylori strains investigated were resistant to metronidazole, ciprofloxacin, and clarithromycin respectively but all were susceptible to amoxicillin and(More)
Arcobacter butzleri isolation from chicken carcasses in Costa Rica is reported for the first time. The isolated strains (P and R) were presumptively identified by their phenotypic characteristics. Definitive identification was made using a multiplex PCR assay for the simultaneous detection and identification of Arcobacter butzleri, Arcobacter cryaerophilus(More)
Helicobacter pylori colonizes more than 50% of the world population thus, it is considered an important cause of gastric cancer. The aim of this study was to determine the isolation frequency of H. pylori in Southern Chile from patients with symptomatology compatible with gastritis or gastric ulcer and to correlate these findings with demographic parameters(More)
Edwarsiella tarda is a zoonotic bacterium that can be isolated from humans, animals and the environment. Although E. tarda is primarily considered a fish pathogen, it is the only species of its genus considered to be pathogenic for humans as well. A survey of zoonotic intestinal bacteria in fresh feces from South American sea lions (SASL) Otaria flavescens,(More)
