differentiation of australian isolates of mycobacterium paratuberculosis using pulsed-field gel electrophoresis.to examine strain variation amongst australian isolates of mycobacterium paratuberculosis.19979469224
specificity of absorbed elisa and agar gel immuno-diffusion tests for paratuberculosis in goats with observations about use of these tests in infected goats.to determine the specificity of serological tests that are currently used in veterinary diagnostic laboratories in australia for detection of mycobacterium avium subsp paratuberculosis infection in goats.200315084016
national atypical mycobacteria survey, 2000.infections with atypical mycobacteria in australia during 2000 occurred at a rate of 1.8 cases per 100,000 population. the main sites of disease were the respiratory tract, soft tissue, and the lymphatics. the mycobacterium avium complex was the most common group of mycobacteria isolated from respiratory, lymphatic sites, and blood. the rapidly growing mycobacteria, predominantly the m. fortuitum-m. abscessus-m. chelonae group were the most common soft tissue infections. atypical mycobacteria we ...200312926733
mycobacterial lymphadenitis in western australia.the records of 172 patients with culture-positive mycobacterial lymphadenitis in western australia between january 1972 and december 1989 inclusive have been reviewed. of the 118 children under 7 years of age, the disease was caused by m. tuberculosis in 4%, the m. avium complex in 74% and m. scrofulaceum in 20%, whereas in the 54 adults aged 15 years and over, the same organisms were responsible for 89%, 2% and 4% respectively of their diseases. tuberculous (tbc) lymphadenitis affected mainly a ...19921292717
an estimate of specificity for a johne's disease absorbed elisa in northern australian cattle.to estimate the specificity of an absorbed enzyme-linked immunosorbent assay kit for johne's disease (jd) when used in mature cattle populations resident in northern australia.200212180881
current value of historical and ongoing surveillance for disease freedom: surveillance for bovine johne's disease in western australia.'confidence' in freedom from disease is generally derived from multiple sources of varied surveillance information, and typically this surveillance evidence has been accumulated over time. in the state of western australia (wa) the main surveillance evidence supporting free zone status in the national bovine johne's disease (bjd) program comprises periodic surveys and the ongoing clinical diagnostic system. this paper illustrates a simple approach to current valuation of historical surveillance ...200818243373
trends in incidence of aids illnesses in australia from 1983 to 1994: the australian aids cohort.to assess time trends in incidence of aids illnesses in australia, a retrospective cohort of people diagnosed with aids from january 1, 1983 to december 31, 1994 in three hiv medicine units in sydney, melbourne, and perth was established. data on initial and subsequent aids illnesses were available for 2580 aids cases, or 45% of australian aids notifications over the study period. males represented 97.2% of the cohort, and hiv exposure category was homosexual contact for 89.9%. subcohorts were f ...19979377123
the western australian hiv cohort study, perth, australia.the efficacy of primary prophylactic treatment for opportunistic infections can be estimated in an observational cohort study by adjusting for clinical and laboratory markers of the immunodeficiency (e.g., oral candidiasis, cd4%, lymphocyte cell counts) as time-dependent co-variates (providing that the treatment does not directly alter the markers). however, the cd4 cell count provides an incomplete measure of the protective immune response, and the efficacy of treatment may be underestimated if ...19989586648
comparison of serological tests and faecal culture for the detection of mycobacterium avium subsp. paratuberculosis infection in cattle and analysis of the antigens involved.three hundred and forty-one sera from cattle in western australia and 106 sera from mycobacterium paratuberculosis faecal culture positive cattle were used to evaluate the performance of two absorbed enzyme-linked immunosorbent assays (elisa) (one locally produced, the other a commercial test) and a complement fixation test (cft) for the detection of johne's disease in cattle. the diagnostic sensitivity (47.2%) of the local elisa was significantly higher than that of the commercial elisa (31.1%) ...199910227475
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
