Fasciola hepatica is a prevalent helminth parasite of livestock. Infection results in polarization the host's immune response and generation type 2 helper (Th2) responses, which are known to be inhibitory Th1 responses. Bovine tuberculosis (BTB) bacterial disease economic zoonotic importance. Control polices for this rely on extensive annual testing test-and-slaughter policy. The correct diagnosis BTB relies cell-mediated We established model coinfection F. Mycobacterium bovis BCG examine...
Rectal swabs were collected from 147 household dogs and 35 cats, including healthy animals, animals with gastrointestinal signs a variety of medical surgical conditions. A combination selective culture methods was used to optimise the recovery Campylobacter species, PCR confirm their isolation identify species. The overall prevalence species 42.9 per cent in cats 41.5 dogs. upsaliensis most commonly isolated jejuni second isolated. Particularly high prevalences detected few diarrhoea, that...

Portugal has one of the highest levels fish consumption globally. Raw or lightly processed is not part traditional diet but rise in popularity such dishes worldwide means that this type food likely to increase Portugal. Anisakiosis a food-borne zoonotic disease associated with raw undercooked fish. An reported incidence occurred recent decades. Our survey aimed gather data on Portugal, looking at sociodemographic and health characteristics individuals who consume (n = 421), as well volume...
Summary 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 was performed all isolates to assess sensitivity each method isolation spp., establish prevalence jejuni , C. coli upsaliensis lari helveticus . Overall 163 (45.2%) samples confirmed spp. positive. Direct plating onto modified charcoal cefoperazone deoxycholate agar (mCCDA) with cefoperazone, amphotericin teicoplanin...
The aim was to exploit whole genome sequencing (WGS) assess genomic diversity, identify virulence genes and deduce the proportion of Campylobacter colonized broilers that directly contaminate their carcasses.Campylobacter jejuni isolates (107) from caeca carcass neck skin samples (50 pairs same batch plus 7 individual caeca) sampled at three poultry slaughterhouses over a one-year period were selected for (MiSeq; Illumina). FastQ files submitted BioNumerics analysis using wgMLST scheme...
Veterinary behaviour medicine should be a foundation subject of the veterinary curriculum because its wide scope applications to practice. Private practitioners are likely primary source information on animal for most pet owners, however studies indicate that behavioural issues not frequently discussed during companion consultations and many lack confidence in dealing with problems, due poor coverage this education. There is need identify learning outcomes support day one competences these...
Parasitic nematodes of the genus Anisakis are causative agent anisakiosis, an important fish-borne zoonosis. Humans infected through consumption raw or undercooked fish, contaminated with parasite. Infection can result in both gastrointestinal and allergic symptoms. There few reports anisakiosis Portugal, but evidence allergy exists, indicating that exposure is occurring population. The European Food Risk Assessment Fellowship Programme (EU-FORA) work programme, entitled: 'Food safety fish...
Foodborne parasitic zoonoses from fish and shellfish products are of significant health concern. Anisakiosis is an important fish-borne zoonosis caused by nematodes the genus Anisakis. Humans infected through consumption raw or undercooked cephalopods containing Anisakis spp. third stage larvae. Infection can result in both gastrointestinal allergic symptoms. Globalization has resulted a growth demand for food, this may increase population at risk anisakiosis. Our study's main aim was to...
This study examined the impact of key processing stages and flock variables on prevalence Campylobacter broiler carcasses. Overall, was 62% in caeca, 68%, 65% neck skin samples collected after evisceration, final wash carcass chilling, respectively. were found 32% 52%, 40% respectively from first thin batches. Final batches more frequently contaminated with prevalences 83% 80% evisceration both chilling (p < 0.05). Thinning status had a significant effect counts significantly higher observed...
Fasciola hepatica is responsible for human disease and economic livestock loss on a global scale. Unlike the well characterized schistosomes, only adult juvenile stages of F. are implicated in disease, whereas freely voided egg not thought to contribute host–parasite interactions. We investigated specific immune responses soluble proteins (SFHEP), during 14-week experimental infection, demonstrating significant increases anti-SFHEP IgG1 (P = 0·001), transforming growth factor beta-1 0·008)...
Campylobacter is the most common food-borne pathogen in European Union. In 2018, crude incidence rate Ireland was 63.6 per 100,000 population. Chicken considered an important source of infection for humans. 2015, Stakeholders' Group (CSG) established to reduce contamination levels Irish broiler flocks.
