molecular epidemiology of mycobacterium avium subsp. paratuberculosis: is900 restriction fragment length polymorphism and is1311 polymorphism analyses of isolates from animals and a human in australia.the distribution and prevalence of strains of mycobacterium avium subsp. paratuberculosis were determined among sheep, cattle, and other species with johne's disease in australia. a total of 328 isolates were evaluated from numerous farms in new south wales, victoria, tasmania, and south australia, australia. restriction fragment length polymorphism (rflp) analysis of genomic dna using bsteii and an is900 probe and is1311 polymorphism analysis using pcr and restriction endonuclease analysis (pcr ...200010970365
comparison of pre- and post-vaccination ovine johne's disease prevalence using a bayesian approach.this study was conducted to evaluate the effectiveness of gudairâ„¢ vaccine in decreasing the prevalence of shedding of mycobacterium avium subsp. paratuberculosis (map) in flocks of varying initial prevalence. thirty-seven self-replacing merino flocks from new south wales and victoria (australia) that had been vaccinating lambs with gudairâ„¢ for at least five years were enrolled in the study. these flocks had been tested prior to or at commencement of vaccination using pooled faecal culture, agar ...201323578910
effect of a test and control program for johne's disease in victorian beef herds 1992-2002.to report on progress in johne's disease (jd) control in infected beef herds participating in the victorian johne's disease test and control program (tcp).200415088984
sensitivity and specificity of two serological tests for the detection of ovine paratuberculosis.to determine the sensitivity and specificity of an absorbed elisa and an agid test for the detection of clinical and subclinical paratuberculosis in sheep.200011194475
inter-laboratory comparison of radiometric culture for mycobacterium avium subsp. paratuberculosis using raw milk from known infected herds and individual dairy cattle in victoria.to compare the results of radiometric culture conducted in three australian laboratories for mycobacterium avium subsp. paratuberculosis (mptb) using bulk vat and individual animal milk samples.201020579029
automation of an absorbed enzyme immunoassay for the detection of mycobacterium paratuberculosis antibodies for an eradication program.as part of an ongoing johne's disease eradication program by the state of victoria, australia, the victorian veterinary pathology services (vvps) has been involved in testing over 150000 cattle samples per year for the presence of johne's-specific antibodies. the parachek kit (csl, victoria, australia) has been used throughout the project. this method was automated using a rosys 3300 and a plato 7 (dade/behring diagnostics) to pipette samples and the behring elisa processor 3 (dade/behring diagn ...200011118720
herd testing to control bovine johne's disease.in 1996, the cattle industries and government in the australian state of victoria established a johne's disease (jd) test and control program under which participating farmers are provided with an annual elisa test of their adult herd and advice on disease control that is tailored to their farm. the program is delivered through private veterinarians under contract with the government. there are over 600 herds enrolled in the program and about one third of these have had three or more whole herd ...200011118727
estimate of the sensitivity of an elisa used to detect johne's disease in victorian dairy cattle herds.to estimate the sensitivity of the elisa used in dairy cattle herds participating in the victorian bovine johne's disease test and control program (tcp).200415478730
herd management practices and the transmission of johne's disease within infected dairy herds in victoria, australia.a retrospective cohort study involving 137 dairy herds randomly selected from all 390 participating in the victorian test and control program for bovine johne's disease was undertaken to gain insight into the relationships between calf rearing practices and the occurrence of bovine johne's disease on infected dairy farms. each study farm was visited between july 2005 and january 2006 and a structured survey examining herd management and calf rearing practices was completed. the resultant data, a ...201020554069
infection rates in reactors to an absorbed elisa used in a test and cull program for bovine johne's disease.to determine the proportion of cattle, whose sera gave positive reactions in a commercial enzyme linked immunosorbent assay (elisa) for bovine johne's disease, that were confirmed infected with mycobacterium avium subsp paratuberculosis by histology and culture of tissues.200415149076
differentiation of australian isolates of mycobacterium paratuberculosis using pulsed-field gel electrophoresis.to examine strain variation amongst australian isolates of mycobacterium paratuberculosis.19979469224
