There are limited data available, in Ireland or elsewhere, to determine the extent of exposure various endemic diseases among beef cows and factors associated with causative pathogens. The objectives this study were herd within prevalence Bovine Viral Diarrhoea Virus (BVDV), Herpes 1 (BHV-1), Leptospirosis Neosporosis a large scale commercial herds on island Ireland, examine level these pathogens herds. average number tested per was 35.5 (median 30).

Abstract Surveillance of endemic pathogens is essential for disease control, providing an evidence base policy and advice. Bovine Herpes Virus Type 1 (BoHV-1), the causative agent Infectious Rhinotracheitis (IBR), has been found to have high seroprevalence within Irish cattle population. The aim present study was establish levels culled in Ireland aged < 30 months whether BVD exposure other factors associated with BoHV-1 exposure. We employed random effects logit models coupled repeated...
Animal Health Ireland has produced clear guidelines for the control of Bovine Viral Diarrhoea (BVD) infection in Irish cattle herds. In course developing these it was that a framework regional and/or national BVD would be required to increase uptake at farm level and reduce overall prevalence disease. This paper assessed economic impact BVD, epidemiological aspects disease its control, models international experiences programmes. The technical knowledge test technology exists eradicate BVD....
Calf output is a key element in determining the profitability of suckler beef enterprise. Infectious agents such as Bovine Virus Diarrhoea (BVD) virus, colostrum management and parasitic challenge can all affect calf output. Prior to national BVD eradication programme, there was little published information on either prevalence or effect Irish herds. There practices commercial herds have also been few studies liver fluke rumen infection Sixteen farms participating Teagasc/Farmers Journal...
Background: Biting midges in the genus Culicoides (Diptera: Ceratopogonidae) act as vectors for several arboviruses, including Bluetongue virus (BTV) and Schmallenberg (SBV), which affect livestock health productivity. In Ireland, limited genetic data are available regarding diversity of species. This study represents first attempt to characterise this region using molecular techniques. Methods: Adult samples were captured Onderstepoort Veterinary Institute (OVI) traps across six locations...

: Milk samples from 285 cows in 15 dairy herds were collected for bacteriological analysis. Cows selected on the basis of a somatic cell count (SCC) exceeding 200,000 cells per ml at three most recent milk recordings prior to sampling. Staphylococcus aureus and Streptococcus uberis predominant isolates accounting 21% (n = 61) 19% 53) isolates, respectively. was more frequently isolated split-calving than spring-calving this difference statistically significant (P < 0.005). Herds with...
Schmallenberg virus (SBV) circulation was investigated in 25 previously exposed dairy herds Ireland 2016. A population of 1,550 spring-2014-born animals, which had been monitored for SBV infection 2014 and 2015 as part a previous surveillance study, were resampled evidence during total 366 blood samples collected the study (15 per herd) between 3 March 2017 10 (before vector-active season) analysed antibodies using competitive ELISA kit (IDVet). 256 animals tested seropositive, an AP 69.9%...
Background: There has been very little previous research in Ireland on the farmers' opinions regarding calf welfare issues. Calf welfare, particularly for male dairy calves, assumed greater importance recent years due, part, to an increase number of cattle over past decade. The objective this study was explore views a broad range issues related expansion herd. Methods: A survey developed capture farmers calves. majority questions were quantitative, and final open-ended question collected...

Schmallenberg virus (SBV) emerged in northern-Europe 2011 resulting an epidemic of ruminant abortions and congenital malformations throughout the continent. In years following there have been reports SBV overwintering continued circulation several European countries. When population-level immunity declines exposed regions, re-introduction could result further outbreaks disease. The aims this study were to determine seroprevalence previously Irish dairy herds 2014 investigate if circulate...
Schmallenberg virus (SBV) was first identified in November 2011. It is a novel Orthobunyavirus (family Bunyaviridae) whose main ill effect congenital malformation of the musculoskeletal and central nervous systems. borne by Culicoides spp., has spread extensively western Europe. The case SBV Ireland diagnosed October 2012. anticipated that once emerged there would be wide scale or nationwide over course 2013 vector season. objectives this study were to determine seroprevalence distribution...
Bovine tuberculosis (bTB) outbreaks, caused by
A national programme to eradicate bovine viral diarrhoea (BVD) has been in place Ireland since 2013. To inform decision making the end stages of eradication, and support development post-eradication surveillance strategies, an understanding risks infection a low prevalence system is required.A case-control study design was implemented. The population comprised herds that had calves born tested negative for BVD virus (BVDV) every year from 2013 2019 (n = 46,219 herds). We defined cases as...
Mycoplasma bovis is a serious disease of cattle worldwide; mastitis, pneumonia, and arthritis are particularly important clinical presentations in dairy herds. was first identified Ireland 1994, the reporting Mycoplasma-associated has substantially increased over last 5 years. Despite presumed endemic nature M. Ireland, there paucity data on prevalence infection, effect this industry. The aim observational study to estimate apparent herd for Irish herds using routinely collected bulk milk...
Bovith recene tuberculosis (bTB) continues to be a pathogen of concern in several countries globally. Analysis areas that have higher incidences bTB outbreaks has demonstrated how risk is not equally distributed, and local data collection, analysis participatory engagement required develop tailored approaches.
