UNLABELLED Campylobacter spp. are the leading cause of bacterial gastroenteritis worldwide, and water is increasingly seen as a risk factor in transmission. Here we describe a most-probable-number (MPN)-quantitative PCR (qPCR) assay in which water samples are centrifuged and aliquoted into microtiter plates and the bacteria are enumerated by qPCR. We observed that commonly used Campylobacter mo...
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 most frequently isolated species.
Arcobacter species have a widespread distribution with a broad range of animal hosts and environmental reservoirs, and are increasingly associated with human illness. To elucidate the routes of infection, several characterization methods such as pulsed-field gel electrophoresis (PFGE), amplified fragment-length polymorphism, and enterobacterial repetitive intergenic consensus (ERIC)-PCR have al...
A study was undertaken to determine the prevalence and diversity of species of the genus Arcobacter in pig and dairy cattle manure, which led to the identification of strains AF1440T, AF1430 and AF1581. Initially identified as Arcobacter butzleri based on colony morphology and initial PCR-confirmation tests, analyses of 16S rRNA gene sequences of these strains confirmed that they belonged to th...
Pigs are important reservoirs for Arcobacter. Since 1978, Arcobacter species have been associated with reproduction disorders, but excretion by clinically healthy pigs has been frequently reported as well. Information on Arcobacter colonization of the porcine gastrointestinal tract is lacking. In the present study, gastrointestinal tracts of 12 pigs were collected, and the content and mucus of ...
Breviatea form a lineage of free living, unicellular protists, distantly related to animals and fungi. This lineage emerged almost one billion years ago, when the oceanic oxygen content was low, and extant Breviatea have evolved or retained an anaerobic lifestyle. Here we report the cultivation of Lenisia limosa, gen. et sp. nov., a newly discovered breviate colonized by relatives of animal-ass...
We designed polymearse chain reaction (PCR) primers to distinguish Campylobacter jejuni from Campylobacter coli and to differentiate Arcobacter from other species of Campylobacter. We applied these PCR methods to estimate their prevalence in feces of healthy cattle and hogs and to identify risk factors for infection. For cattle, C. jejuni (23%), Arcobacter (11%), and C. coli (1.57%) were detect...
