| epizootiology of chlamydia infections in two free-range koala populations. | the prevalence of chlamydia pecorum and chlamydia pneumoniae infections in two free-range koala populations was assessed using genus-specific pcr combined with species-specific dna probe hybridisation. population a had a very high overall level of chlamydial infection (85%) with significantly more of these infections being due to c. pecorum (73%) compared to c. pneumoniae (24%). the second population had a much lower prevalence of infection (10%) with equal levels of both species. an important f ... | 1999 | 10223324 |
| within-population diversity of koala chlamydophila pecorum at ompa vd1-vd3 and the orf663 hypothetical gene. | infection of koalas by chlamydophila pecorum is very common and causes significant morbidity, infertility and mortality. fundamental to management of the disease is an understanding of the importance of multi-serotype infection or pathogen virulence in pathogenesis; these may need consideration in plans involving koala movement, vaccination, or disease risk assessment. here we describe diversity of ompa vd1-3, and orf663 hypothetical gene tandem repeat regions, in a single population of koalas w ... | 2011 | 22118784 |
| identification of unusual chlamydia pecorum genotypes in victorian koalas (phascolarctos cinereus) and clinical variables associated with infection. | chlamydia pecorum infection is a threat to the health of free-ranging koalas (phascolarctos cinereus) in australia. utilizing an extensive sample archive we determined the prevalence of c. pecorum in koalas within six regions of victoria, australia. the ompa genotypes of the detected c. pecorum were characterized to better understand the epidemiology of this pathogen in victorian koalas. despite many studies in northern australia (i.e. queensland and new south wales), prior chlamydia studies in ... | 2016 | 26932792 |
| the prevalence and clinical significance of chlamydia infection in island and mainland populations of victorian koalas (phascolarctos cinereus). | chlamydia infection is known to impact the health of koalas (phascolarctos cinereus) in new south wales (nsw) and queensland, but the clinical significance of chlamydia infections in victorian koalas is not well described. we examined the prevalence of chlamydia infection and assessed associated health parameters in two victorian koala populations known to be chlamydia positive. the same testing regimen was applied to a third victorian population in which chlamydia had not been detected. we exam ... | 2015 | 25588005 |
| longitudinal prevalence and faecal shedding of chlamydia pecorum in sheep. | the prevalence and faecal shedding of chlamydia spp. in sheep in australia has not been well described. two species-specific quantitative pcrs (qpcrs) targeting the chlamydial outer membrane protein cell surface antigen gene (ompa) were validated and used to determine the prevalence and faecal shedding of c. abortus and c. pecorum from faecal samples of lambs at three sampling times (weaning, post-weaning and pre-slaughter) from eight farms in south australia, new south wales, victoria and weste ... | 2014 | 24954870 |
