campylobacter helveticus sp. nov., a new thermophilic species from domestic animals: characterization, and cloning of a species-specific dna probe. | an atypical group of thermophilic catalase-negative campylobacter strains, the 'ch' (swiss) group, can be recovered from faeces of domestic cats and dogs after selection by filtration, or with the antibiotic cefoperazone. this group of strains shows no relative dna homology with any species in rrna superfamily vi (vandamme et al., 1991, international journal of systematic bacteriology 41, 88-103) except with four thermophilic campylobacter species, notably c. upsaliensis. the group is homogeneou ... | 1992 | 1479353 |
two types of 16s rrna gene are found in campylobacter helveticus: analysis, applications and characterization of the intervening sequence found in some strains. | in the recently described species campylobacter helveticus, two sizes of pcr amplicon were detected with primers homologous to conserved regions of the 16s rrna gene. a conventionally sized gene was sequenced from the type strain, nctc 12470, placing the new species as phylogenetically related to c. upsaliensis and the thermotolerant campylobacters. this nucleotide sequence enabled pcr primers to be designed for use in rapid molecular identification of c. helveticus and its closest phylogenetic ... | 1994 | 7516795 |
isolation of helicobacter canis from a colony of bengal cats with endemic diarrhea. | on the basis of biochemical, phenotypic, and 16s rrna analyses, helicobacter canis was isolated from bengal cats with and without chronic diarrhea. because the cats were coinfected with other potential pathogens, including campylobacter helveticus, and because h. canis was isolated from nondiarrheic cats, the causal role of h. canis in producing the diarrhea could not be proven. histologically, the colons of the four affected cats were characterized by mild to moderate neutrophilic, plasmacytic, ... | 1999 | 10488191 |
coinfection of enteric helicobacter spp. and campylobacter spp. in cats. | during a 6-year period, 64 of 227 commercially reared cats had microaerobic bacteria isolated from their feces. all the isolates were initially identified as campylobacter-like organisms based on biochemical and phenotypic characteristics. dna extractions from 51 of these isolates were subjected to pcr using primers specific for helicobacter spp. and campylobacter spp. of the isolates, 92% (47 of 51 isolates) were positive for campylobacter spp., 41% (21 of 51 isolates) were positive for helicob ... | 2001 | 11376052 |
genomic heterogeneity and o-antigenic diversity of campylobacter upsaliensis and campylobacter helveticus strains isolated from dogs and cats in germany. | a serotyping scheme based on heat-stable surface antigens was established for 101 campylobacter upsaliensis and 10 campylobacter helveticus strains isolated from 261 dogs and 46 cats of different ages originating from two geographically distinct regions in germany. the prevalence of c. upsaliensis varied between 27.8% in juvenile dogs (<12 months of age) and 55.4% in adult dogs (p < 0.05). of the cats, 19.6% harbored c. upsaliensis, whereas 21.7% carried c. helveticus. of the c. upsaliensis isol ... | 2001 | 11427567 |
differentiation of campylobacter species by aflp fingerprinting. | the fluorescent amplified fragment length polymorphism (aflp) fingerprinting method was tested for its ability to identify and subtype the most important campylobacter species found in veterinary infections. sixty-nine reference strains and 19 clinical isolates of campylobacter jejuni subsp. jejuni, campylobacter jejuni subsp. doylei, campylobacter upsaliensis, campylobacter coli, campylobacter lari, campylobacter fetus subsp. fetus, c. fetus subsp. venerealis, campylobacter hyointestinalis subs ... | 2001 | 11577152 |
campylobacter insulaenigrae isolates from northern elephant seals (mirounga angustirostris) in california. | there are only two reports in the literature demonstrating the presence of campylobacter spp. in marine mammals. one report describes the isolation of a new species, campylobacter insulaenigrae sp. nov., from three harbor seals (phoca vitulina) and a harbor porpoise (phocoena phocoena) in scotland, and the other describes the isolation of campylobacter jejuni, campylobacter lari, and an unknown campylobacter species from northern elephant seals (mirounga angustirostris) in california. in this st ... | 2007 | 17259365 |
campylobacter cuniculorum sp. nov., from rabbits. | eight strains of an unknown thermotolerant campylobacter species were isolated from the caecal contents of rabbits (oryctolagus cuniculus). all strains were initially identified as belonging to the genus campylobacter by means of genus-specific pcr, but none were identified using species-specific pcr for known thermophilic species. cells were spiral shaped with bipolar unsheathed flagella, with no periplasmic fibres, and appeared coccoid after 10-12 days of incubation. phylogenetic analyses base ... | 2009 | 19542108 |
campylobacter troglodytis sp. nov., isolated from feces of human-habituated wild chimpanzees (pan troglodytes schweinfurthii) in tanzania. | the transmission of simian immunodeficiency and ebola viruses to humans in recent years has heightened awareness of the public health significance of zoonotic diseases of primate origin, particularly from chimpanzees. in this study, we analyzed 71 fecal samples collected from 2 different wild chimpanzee (pan troglodytes) populations with different histories in relation to their proximity to humans. campylobacter spp. were detected by culture in 19/56 (34%) group 1 (human habituated for research ... | 2011 | 21278267 |
helicobacter marmotae, novel helicobacter sp. and campylobacter sp. isolated from livers and intestines of prairie dogs. | prairie dogs (cynomys ludovicianus) are used to study the etiology and prevention of gallstones because of the similarities of prairie dog and human bile gallstone composition. epidemiologic and experimental studies have suggested a connection between helicobacter spp. infection and cholesterol cholelithiasis, cholecystis and gallbladder cancer. ten of thirty four prairie dogs in our study had positive helicobacter spp. identified by pcr with helicobacter genus-specific primers (c97, co5). fourt ... | 2011 | 21546560 |
isolation of campylobacter spp. from client-owned dogs and cats, and retail raw meat pet food in the manawatu, new zealand. | campylobacter causes acute gastroenteritis in people worldwide and is frequently isolated from food, animals and the environment. the disease is predominately food-borne but many routes of transmission and sources of infection have been described, including contact with pets. the prevalence of campylobacter spp. in dogs and cats varies widely, and data on new zealand pets are limited. this study aimed to investigate the prevalence of campylobacter spp. in dogs, cats and retail raw meat pet food ... | 2016 | 27860343 |
occurrence and characteristics of fastidious campylobacteraceae species in porcine samples. | this study investigated the prevalence and characteristics of campylobacteraceae including a range of fastidious species in porcine samples. over a thirteen month period caecal contents (n=402) and pork carcass swabs (n=401) were collected from three pork abattoirs and pork products (n=399) were purchased at point of sale in the republic of ireland. campylobacteraceae isolates were recovered by enrichment, membrane filtration and incubation in antibiotic free media under a modified atmosphere (3 ... | 2013 | 23474652 |
variation in the limit-of-detection of the prospect campylobacter microplate enzyme immunoassay in stools spiked with emerging campylobacter species. | campylobacter enteritis in humans is primarily associated with c. jejuni/coli infection. the impact of other campylobacter spp. is likely to be underestimated due to the bias of culture methods towards campylobacter jejuni/coli diagnosis. stool antigen tests are becoming increasingly popular and appear generally less species-specific. a review of independent studies of the prospect® campylobacter microplate enzyme immunoassay (eia) developed for c. jejuni/coli showed comparable diagnostic result ... | 2016 | 27317896 |
complete genome sequence of the campylobacter helveticus type strain atcc 51209. | campylobacter helveticus has been isolated from domestic dogs and cats. although c. helveticus is closely related to the emerging human pathogen c. upsaliensis, no c. helveticus-associated cases of human illness have been reported. this study describes the whole-genome sequence of the c. helveticus type strain atcc 51209 (=ccug 30682t). | 2017 | 28546490 |
