Johne's disease was identified in sheep flocks on 6 farms in one area of the central tablelands of New South Wales. The sources of infection were not determined and no common source of all infections was identified. The disease was not diagnosed in cattle that were run on 4 of the farms.

One hundred thirty-three patients were examined for the presence of a cutaneous eruption consisting of small, asymptomatic, hypopigmented, follicular papules on the upper part of the trunk. The papules were present in 57% of patients who had a history of acne vulgaris and in 9% of patients who denied ever having had acne. Biopsy specimens from five patients revealed circumscribed, perifollicular or parafollicular lesions in which both elastic and collagen fibers were attenuated in comparison with those in normal adjacent dermis. These changes are consistent with scar. We conclude that the papules are a scarring process secondary to acne vulgaris and propose calling the lesions papular acne scars. They appear closely related to or identical with changes previously termed perifollicular elastolysis, postacne anetoderma-like scars, and papular elastorrhexis.

In a recent report Coman (1973) concluded that foxes play no part in the transmission of cysticercoses to domestic livestock in Victoria. This conclusion was based on a survey of 1,320 foxes examined from all parts of Victoria, in which none was found to be infected with Taenia ovis, T. hydatigena or Echinococcus gruriulmus. In contrast, Pullar (1946) had found 13.5% (9/67) and 1.2% (1167) of foxes from the Gippsland district of Victoria were infected with T . ovis and T . hydatigena respectively.A pilot survey was carried out to determine whether foxes should be included in a program to control T. ovis
