Fasciola hepatica is a prevalent helminth parasite of livestock. Infection results in polarization of the host's immune response and generation of type 2 helper (Th2) immune responses, which are known to be inhibitory to Th1 responses. Bovine tuberculosis (BTB) is a bacterial disease of economic and zoonotic importance. Control polices for this disease rely on extensive annual testing and a test-and-slaughter policy. The correct diagnosis of BTB relies on cell-mediated immune responses. We established a model of coinfection of F. hepatica and Mycobacterium bovis BCG to examine the impact of helminth infection on correct diagnosis. We found the predictive capacity of tests to be compromised in coinfected animals and that F. hepatica infection altered macrophage function. Interleukin-4 and gamma interferon expression in whole-blood lymphocytes restimulated in vitro with M. bovis antigen was also altered in coinfected animals. These results raise the question of whether F. hepatica infection can affect the predictive capacity of tests for the diagnosis of BTB and possibly also influence susceptibility to BTB and other bacterial diseases. Further studies on the interplay between helminth infection and BTB are warranted.

Rectal swabs were collected from 147 household dogs and 35 household cats, including healthy animals, animals with gastrointestinal signs and animals with a variety of medical and surgical conditions. A combination of selective culture methods was used to optimise the recovery of Campylobacter species, and a PCR was used to confirm their isolation and to identify the species. The overall prevalence of Campylobacter species was 42.9 per cent in the cats and 41.5 per cent in the dogs. Campylobacter upsaliensis was the species most commonly isolated from the dogs and cats, and Campylobacter jejuni was the second most commonly isolated. Particularly high prevalences were detected in the few cats and dogs with diarrhoea, and in the cats and dogs that were six months old or younger.

Five culture methods for the recovery of Campylobacter species (spp.) were evaluated on 361 rectal swabs collected from cats and dogs in Ireland. Speciation using PCR methods was performed on all isolates to assess the sensitivity of each culture method for isolation of Campylobacter spp., and to establish the prevalence of Campylobacter jejuni, C. coli, C. upsaliensis, C. lari and C. helveticus. Overall 163 of 361 (45.2%) samples were confirmed Campylobacter spp. positive. Direct plating onto modified charcoal cefoperazone deoxycholate agar (mCCDA) with cefoperazone, amphotericin and teicoplanin (CAT) selective supplement yielded a significantly higher prevalence of Campylobacter spp. (33.0%) than each of the other four methods (P < or = 0.05). This method was also the most sensitive method for isolation of C. upsaliensis compared with any of the other four methods used in the current study (P < or = 0.05). A direct plating method onto mCCDA agar with CCDA selective supplement and a filtration method onto blood agar after pre-enrichment in CAT supplemented broth yielded lower Campylobacter spp. prevalences of 19.7% and 17.5% respectively. A filtration method onto CAT agar and pre-enrichment in Preston broth before plating onto mCCDA agar were less sensitive for the isolation of Campylobacter spp. Speciation results of Campylobacter isolates revealed the majority of Campylobacter isolates were C. upsaliensis (50.0%) and C. jejuni (41.9%). A small number of isolates were C. coli (2.6%), C. lari (1.5%) and C. helveticus (1.1%). The overall detection of Campylobacter spp. in the 361 pets sampled was significantly increased by using a combination of isolation methods (P < or = 0.05), producing a more accurate determination of the prevalence of Campylobacter spp. in pets in Ireland and of the actual Campylobacter species. As the majority of Campylobacter spp. were recovered by direct plating onto mCCDA agar with CAT supplement, this method is the method of choice if only a single method is selected for isolation of the most common Campylobacter spp. detected in pets and humans.

BackgroundVeterinary behaviour medicine should be a foundation subject of the veterinary curriculum because of its wide scope of applications to veterinary practice. Private practitioners are likely to be the primary source of information on animal behaviour for most pet owners, however studies indicate that behavioural issues are not frequently discussed during companion animal consultations and many practitioners lack confidence in dealing with behavioural problems, likely due to poor coverage of this subject in veterinary education.There is a need to identify learning outcomes to support day one competences in veterinary behaviour medicine and these should be informed by practice-based evidence. This study aimed to investigate the nature and frequency of behavioural queries experienced by veterinary professionals in Ireland, the provision of behavioural services at companion animal practices, behaviour referral practices and challenges associated with providing a behaviour service.MethodsTwo online surveys were developed, one for private veterinary practitioners (PVP) and one for veterinary nurses (VN). Invitations to participate were distributed using contact details from the Premises Accreditation Scheme database on the Veterinary Council of Ireland website. Thirty-eight PVPs and 69 VNs completed the survey.ResultsResults indicated that less than half of companion animal practices offer behavioural consults and under a third of practices provide training and socialization events. Over half of the practices surveyed have referred cases to a behavioural specialist.The majority of respondents encountered behavioural queries weekly. Ninety-eight percent reported receiving queries regarding dog behaviour. Toilet training and unruly behaviour were two issues encountered frequently. Behavioural issues in cats were also common. House soiling and destructive behaviour were the problems most frequently encountered by respondents.The two most commonly cited barriers to providing behavioural consultations were lack of in-house or personal expertise, and that clients were not willing to pay for these services.Furthermore over half of all veterinary professionals surveyed indicated that they had received inadequate undergraduate training in veterinary behaviour medicine.ConclusionsBehavioural problems in companion animals can affect the quality of life of pets and their owners. Our survey findings indicate that many veterinary professionals frequently encounter behavioural problems and identify an opportunity for improved provision in behaviour medicine in veterinary education.Electronic supplementary materialThe online version of this article (10.1186/s13620-018-0123-3) contains supplementary material, which is available to authorized users.
