A serological survey of leptospirosis in Gippsland dairy farmers.

Serological testing for leptospirosis was performed on sera from 1074 persons who were attending the 1983 Gippsland Field Days. The most common serological reactions were against representative serovars from serogroups Hebdomadis (12%), Panama (2%), Tarassovi (2%) and Pomona (1%). The reactions against serogroup Hebdomadis were attributed to exposure to serovar hardjo; the milking of dairy cows was found to be a major risk factor. The high prevalence of seropositive results among clinically normal dairy farmers highlights the need for caution in interpreting the results of laboratory testing for leptospirosis.

Salmonellosis in transported feral goats.

An outbreak of acute diarrhoea and deaths was investigated in a group of 1,016 feral goats of varying ages, on a 400 hectare Gippsland pine plantation. The goats had recently been captured in north western New South Wales and transported by truck to Melbourne, Victoria, a journey of 20 to 25 hours, and maintained in holding yards for up to 10 days. They were then transported for a further 3 hours, and released in the Gippsland plantation. Within 1 to 2 weeks of release many goats developed acute, severe diarrhoea, weakness and recumbency. Thirty-eight percent of all goats died in the first 2 months on the farm. Autopsy findings were characteristic of salmonellosis in 13 (43%) of the 30 goats examined and Salmonella sp were cultured from these and one other goat (47%). Four different serotypes of Salmonella were represented (S. adelaide, S. typhimurium, S. muenchen, S. singapore). The findings support the view that stress due to transport and intensive handling caused carriers of Salmonella to develop into active excretors with high cross infection to susceptible goats.
