“…The prevalence of dermatophilosis was directly related to average annual rainfall and this relationship varied with age of sheep. This is consistent with the observations that wetting of the fleece and skin assists the transmission of and infection by D. congolensis (Roberts 1967;Le Riche 1968) and that dermatophilosis is more prevalent in wet seasons (Graham 1964;Austwick 1976).…”

A random sample of 200 Merino sheep owners was interviewed by telephone during April 1983 and asked questions relating to the prevalence of ovine dermatophilosis in their flocks, methods used for prevention and treatment of dermatophilosis, management strategies employed and the location and annual rainfall of each farm. The response rate was 99.5%. During the previous 12 months 62.3% of farmers had observed dermatophilosis in their flocks. The prevalence within flocks was highest in hoggets (mean 2.2%, range 0 to 75%) followed by lambs (mean 0.8%, range 0 to 25%), ewes (mean 0.6%, range 0 to 20%) and wethers (0.2%, range 0 to 20%). The mean weight of wool identified as affected by dermatophilosis was 58 kg (range 0 to 882 kg). Preventive measures were used on 57% of farms and the most common methods were changes in dipping practice (23.6%) and culling of affected sheep (21%). An average of 13.7 sheep per farm were culled for dermatophilosis and of these, 82% were sold and the remainder (18%) were killed on the farm. Antibiotics, of which most were combinations of penicillin and streptomycin were used to treat dermatophilosis on 8.5% of farms and treatments other than antibiotics were used on 10% of farms. The prevalence of dermatophilosis and its relationship to various environmental and management factors varied with the age and sex of sheep. Discriminant analysis indicated that of the factors studied, average annual rainfall, month of lambing, average fibre diameter and the month ewes were shorn were related to the prevalence of dermatophilosis in lambs.(ABSTRACT TRUNCATED AT 250 WORDS)

“…Transmission of dermatophilosis between the sheep is aided by their tendency to seek shelter and to crowd during heavy rainstorms (AUSTWICK 1976, LE RICHE, 1968. WILKINSON (1979) even reported an association between sheep dipping and morbidity of dermatophilosis.…”

Summary A retrospective study is presented here in which an outbreak of dermatophilosis and morbidity of fleece rot in a sheep herd grazing throughout the year in the Carmel hills are described for the first time in a Mediterranean climatic zone. Both diseases were closely related to intense and prolonged rains during the winter months of 1991/1992. Morbidity of dermatophilosis appeared after 650 mm and that of fleece rot after 1320 mm of precipitation. The pathogenesis of these diseases is discussed.
