title: The distribution and prevalence of stephanofilariasis in cattle in Queensland.
abstract: A total of 10,543 cattle from 1,386 farms throughout Queensland was examined at abattoirs and the presence of stephanofilarial lesions was related to property of origin, sex, breed, and age of the slaughtered cattle and season of slaughter. The mean prevalence was 38% and within the infected area this varied from less than 5% in south east Queensland to 95% on Cape York Peninsula. The prevalence of lesions was higher in bulls than in steers [corrected] and was least in cows [corrected]. Bos indicus animals had a lower prevalence than B. taurus. Prevalence increased with age. The distribution of the disease closely matched that of the buffalo fly, Haematobia irritans exigua.
