zoonotic infections in northern ireland farmers.evidence of past zoonotic infection was investigated serologically in randomly selected northern ireland farmers. the percentage of farmers with antibody was: brucella abortus (0.7), leptospira interrogans serovars (8.1), borrelia burgdorferi (14.3), toxoplasma gondii (73.5), coxiella burnetii (28.0), chlamydia psittaci (11.1) and hantavirus (1.2). the results show that northern ireland farmers have been exposed in the past to zoonotic infections. it is not known if these infections contributed ...19902123457

epidemiology of bovine brucellosis in northern ireland between 1990 and 2000.between 1990 and 2000, 317 herds of cattle in northern ireland were identified as being seropositive to brucella abortus, and 68 per cent of them were attributed to transmission from neighbouring herds or to local spread. of particular significance were three primary outbreaks in 1997, which resulted in significant secondary and tertiary spread. three spatial clusters were identified, corresponding to two of the primary outbreaks, and the herd density and within-herd spread were highest in the l ...200616731701
risk associated with animals moved from herds infected with brucellosis in northern ireland.the movement of cattle from herds infected with brucella abortus was investigated in order to assess the control measures for eradication of brucellosis from the cattle population of northern ireland. using recorded cattle movement data, a historical cohort study was designed and carried out to quantify the risk of seropositivity in bovine animals moved from herds infected with brucellosis. the study found that 3.1% of animals, moved in the 6-month period prior to disclosure of infection in the ...200818207262
molecular epidemiology of brucella abortus in northern ireland-1991 to 2012.brucellosis is the most common bacterial zoonoses worldwide. bovine brucellosis caused by brucella abortus has far reaching animal health and economic impacts at both the local and national levels. alongside traditional veterinary epidemiology, the use of molecular typing has recently been applied to inform on bacterial population structure and identify epidemiologically-linked cases of infection. multi-locus variable number tandem repeat vntr analysis (mlva) was used to investigate the molecula ...201526325586
latent class regression models for simultaneously estimating test accuracy, true prevalence and risk factors for brucella 2003/2004 a field trial was conducted in northern ireland to assess the diagnostic accuracy of six serological tests for bovine brucellosis caused by brucella abortus. whereas between-test comparisons have been used to calculate test performances so far, the present study used a latent class approach to estimate diagnostic test accuracy parameters in the absence of a gold standard for these six tests simultaneously and to estimate the true prevalence, while accounting for clustering in the st ...201627245291
