examination of soil in the brisbane area for organisms of the mycobacterium avium-intracellulare-scrofulaceum complex. 19744472106
association of microsatellite polymorphisms with immune responses to a killed mycobacterium avium subsp. paratuberculosis vaccine in merino sheep.to study the association of polymorphisms at five microsatellite loci with immune responses to a killed mycobacterium avium subsp. paratuberculosis (map) vaccine.201020927174
gastroesophageal reflux disease, acid suppression, and mycobacterium avium complex pulmonary disease.weekly symptoms of gastroesophageal reflux disease (gerd) occur in 20% of the population, and gerd has been implicated in the pathophysiology of many respiratory diseases. microaspiration of contaminated water is a potential portal of entry for mycobacterium avium complex (mac) organisms into the respiratory tract, and acid-suppression therapy may enhance the survival of mycobacteria in the stomach. this study aimed to assess the prevalence of gerd, swallowing disorders, reflux symptoms, and aci ...200717426224
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
progress in national control and assurance programs for ovine johne's disease in australia.since the detection of ovine johne's disease in australia in 1980, 578 flocks have been diagnosed as infected, with 442 of these still infected. the disease was initially believed to be confined to the central tablelands area of nsw, but has subsequently been shown to be more widely distributed. sheep strains of m. paratuberculosis are known to infect sheep and goats in south-eastern australia. although sheep strains have recently been identified in some cattle in australia, epidemiological evid ...200011118726
isolation of the mycobacterium avium-m. intracellulare-m. scrofulaceum complex from tank water in queensland, australia.disease-associated serotypes of mycobacterium intracellulare and m. avium have been isolated from 32 of 141 rainwater tanks situated in the basin of the fitzroy river and its tributaries in central queensland, 7 of 32 tanks situated in the hinterland of the coastal city of rockhampton, and 2 of 32 tanks sampled repetitively in the southeastern queensland city of toowoomba. m. gordonae was also isolated from 23 of the river basin tanks, from 9 in the rockhampton hinterland, and from 5 in the city ...19807356321
infections with mycobacterium avium and battey strain (serotype davis) in man in queensland. 19685670870
mycobacterium avium associated with chronic pulmonary disease in a queensland resident.bacteriological investigation over an 11-year period has implicated mycobacterium avium ser i as the most probable cause of chronic pulmonary disease in a resident of south-eastern queensland. although the patient had contact with domestic fowls and a pet budgerigar, the source of the organism is uncertain.1978683698
tuberculin hypersensitivity following bcg vaccination in brisbane school children.seven hundred and fifty brisbane school children were tuberculin tested, in paired groups, with purified protein derivatives of mycobacterium tuberculosis, bovis, bcg and avium. reaction to avian ppd were stronger than to any of the others used. this finding may be of some importance in interpreting the variation in protection afforded by bcg vaccination.1979112744
human health risks for legionella and mycobacterium avium complex (mac) from potable and non-potable uses of roof-harvested rainwater.a quantitative microbial risk assessment (qmra) of opportunistic pathogens legionella pneumophila (lp) and mycobacterium avium complex (mac) was undertaken for various uses of roof-harvested rainwater (rhrw) reported in queensland, australia to identify appropriate usages and guide risk management practices. risks from inhalation of aerosols due to showering, swimming in pools topped up with rhrw, use of a garden hose, car washing, and toilet flushing with rhrw were considered for lp while both ...201728500949
variable-number tandem repeats genotyping used to aid and inform management strategies for a bovine johne's disease incursion in tropical and subtropical australia.the application of variable-number tandem repeats (vntr) genotyping of mycobacterium avium subsp. paratuberculosis isolates to assist in investigating incidents of bovine johne's disease in a low-prevalence region of australia is described in the current study. isolates from a response to detection of bovine johne's disease in queensland were compared with strains from national and international sources. the tandem application of mycobacterial interspersed repetitive unit (miru) and multilocus s ...201425139793
changing epidemiology of pulmonary nontuberculous mycobacteria infections.nontuberculous mycobacteria (ntm) disease is a notifiable condition in queensland, australia. mycobacterial isolates that require species identification are forwarded to the queensland mycobacterial reference laboratory, providing a central opportunity to capture statewide data on the epidemiology of ntm disease. we compared isolates obtained in 1999 and 2005 and used data from the queensland notification scheme to report the clinical relevance of these isolates. the incidence of notified cases ...201020875283
identification of mycobacterium avium subsp avium in an alpaca with lesions resembling paratuberculosis. 200315086098
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
notification of nontuberculous mycobacteria: an australian perspective.in queensland, australia, all cases of mycobacterial infection (tuberculosis [tb] and nontuberculous mycobacteria [ntm]) are notifiable under the queensland public health act (2005). this process originally emerged to avoid ntm confounding with notification of cases of tb, but has facilitated awareness of the increasing incidence and changing epidemiology of ntm. although initially not a public health priority, the notification process has facilitated research that has led to an appreciation of ...201728118021
