| substitute sweeteners: diverse bacterial oligosaccharyltransferases with unique n-glycosylation site preferences. | the central enzyme in the campylobacter jejuni asparagine-linked glycosylation pathway is the oligosaccharyltransferase (ost), pglb, which transfers preassembled glycans to specific asparagine residues in target proteins. while c. jejuni pglb (cjpglb) can transfer many diverse glycan structures, the acceptor sites that it recognizes are restricted predominantly to those having a negatively charged residue in the -2 position relative to the asparagine. here, we investigated the acceptor-site pref ... | 2015 | 26482295 |
| fecal microbiota of cats with naturally occurring chronic diarrhea assessed using 16s rrna gene 454-pyrosequencing before and after dietary treatment. | the gastrointestinal (gi) microbiota has a strong impact on the health of cats and these populations can be altered in gi disease. little research has been done to associate improvement in diarrhea with changes in gi microbiota. | 2013 | 24592406 |
| 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 of pathogens in wild rodents caught on swedish pig and chicken farms. | a total of 207 wild rodents were caught on nine pig farms, five chicken farms and five non-farm locations in sweden and surveyed for a selection of bacteria, parasites and viruses. lawsonia intracellularia and pathogenic yersinia enterocolitica were only detected in rodents on pig farms (9% and 8% prevalence, respectively) which indicate that these agents are more likely to be transmitted to rodents from pigs or the environment on infected farms. brachyspira hyodysenteriae (1%), brachyspira inte ... | 2013 | 23174339 |
| isolation, identification and differentiation of campylobacter spp. using multiplex pcr assay from goats in khartoum state, sudan. | the aim of this study was to identify and characterize thermophilic campylobacter species in faecal samples from goats in khartoum state, sudan, by application of multiplex polymerase chain reaction. campylobacteriosis is a zoonotic disease of global concern, and the organisms can be transmitted to human via food, water and through contact with farm animals and pets. there are five clinically related campylobacter species: campylobacter jejuni (c. jejuni). campylobacter coli, campylobacter lari, ... | 2017 | 28160162 |
| a new variant of cytolethal distending toxin in a clinical isolate of campylobacter hyointestinalis. | increasing numbers of campylobacter hyointestinalis have been isolated from humans and animals with gastroenteritis, although the virulence mechanism of this species remains largely unknown. here, we show that c. hyointestinalis isolated from a patient with diarrhoea in thailand produced a novel variant of cytolethal distending toxin (cdt). sequencing of a 13 965 bp genomic region of c. hyointestinalis carrying the genes coding for ch-cdt revealed three orfs of 798, 804 and 537 bp, which code fo ... | 2015 | 26220191 |
| genotypes and antibiotic resistance of canine campylobacter jejuni isolates. | campylobacter jejuni is the most important cause of bacterial gastroenteritis in humans. it is a commensal in many wild and domestic animals, including dogs. whereas genotypes of human and chicken c. jejuni isolates have been described in some detail, only little information on canine c. jejuni genotypes is available. to gain more information on genotypes of canine c. jejuni and their zoonotic potential, isolates from routine diagnostics of diarrheic dogs as well as isolates of a prevalence stud ... | 2014 | 24210812 |
| high incidence of campylobacter concisus in gastroenteritis in north jutland, denmark: a population-based study. | the incidence of non-thermophilic campylobacter species was assessed in an unselected population-based study in a mixed urban and rural community in north jutland, denmark. in a 2-year study period, 11,314 faecal samples from 8302 patients with gastroenteritis were cultured with supplement of the filter method. we recovered a high incidence of campylobacter concisus (annual incidence 35/100,000 inhabitants), almost as high as the common campylobacter jejuni/coli. in contrast, there was a very lo ... | 2013 | 22512739 |
| 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 |
| campylobacter spp., c. jejuni and c. upsaliensis infection-associated factors in healthy and ill dogs from clinics in cordoba, spain. screening tests for antimicrobial susceptibility. | a microbiological and epidemiological survey examining campylobacter species-related infection in dogs from clinics in cordoba (southern spain) was performed from may 2007 to march 2008. three-hundred and six rectal swabs were taken from both ill and healthy dogs, and an epidemiological questionnaire was filled out. the isolated bacterial strains were identified by means of multiplex polymerase chain reaction (pcr). the prevalence factors for campylobacter spp., c. jejuni and c. upsaliensis infe ... | 2012 | 22640550 |
| campylobacter upsaliensis isolated from dogs produces high titer of cytolethal distending toxin. | cytolethal distending toxin (cdt) consisting of cdta, cdtb and cdtc has been reported to be a possible virulence factor of campylobacters including campylobacter upsaliensis. in our previous study, the cdtb gene-based pcr-restriction fragment length polymorphism (rflp) assay for detection and differentiation of 7 campylobacter species yielded 3 different rflp patterns (cu-i to cu-iii). in this study, entire cdt (cucdt) genes of each pattern were sequenced to see whether there are any differences ... | 2017 | 28202878 |
| molecular characterisation of a type iii restriction-modification system in campylobacter upsaliensis. | two examples of campylobacter upsaliensis rm3195 and jv21 strains are shown to carry putative type iii restriction (res)-modification (mod) enzyme gene clusters, following genome sequence analyses. it is suggested that the cluster is composed of at least three structural genes, res, internal methylase gene and mod, in the strains, based on the nucleotide sequence information. a ribosome binding site, a putative promoter consisting of a consensus sequence at the -10-like structure and a semiconse ... | 2014 | 24974681 |
| a cross-sectional study examining campylobacter and other zoonotic enteric pathogens in dogs that frequent dog parks in three cities in south-western ontario and risk factors for shedding of campylobacter spp. | an estimated 6 million pet dogs live in canadian households with the potential to transmit zoonotic pathogens to humans. dogs have been identified as carriers of salmonella, giardia and campylobacter spp., particularly campylobacter upsaliensis, but little is known about the prevalence and risk factors for these pathogens in pet dogs that visit dog parks. this study examined the prevalence of these organisms in the faeces of dogs visiting dog parks in three cities in south-western ontario, as we ... | 2014 | 23802765 |
