Fleece-rot: the epidemiology and significance of the disease in sheep.

Fleece-rot is a disease of sheep manifested by a superficial dermatitis with seropurulent exudation and matting and, in some cases, pigmentation of wool which occurs following periods of excessive wetness. In Australia it is recognised as the most important predisposing factor to body blowfly strike, and as such represents a major loss to the Australian wool growing industry. This review of the literature suggests that there is no reason for the condition not to be intermittently a significant problem under South African conditions. A long term solution to the problem is achieved by the breeding of resistant sheep. Measurement of fleece wettability is possibly the best method of distinguishing resistant from susceptible sheep.

Field assessment of permethrin in the control of sheep headfly disease.

Three groups of sheep, gimmers, ewes with lambs and rams, were sprayed at fortnightly intervals from June to September 1980 with a 0.1 per cent emulsion of permethrin in an attempt to control damage caused by Hydrotaea irritans. Complete prevention of damage was not achieved but the number of sheep affected and the severity of lesions present in affected sheep was significantly reduced in comparison with untreated control groups. Permethrin treatment was also judged to be valuable in the management of rams with head wounds. Variation in susceptibility with age was noted, gimmers being the most severely affected and a breed variation was apparent in the rams which was related to the character of horn present.

Tick virus diseases of sheep and goats.

Tick-borne viruses affecting sheep and goats can be be locally important diseases. Viruses of the tick-borne encephalitis complex occur across Europe to North-East Asia and are the cause of significant losses in small ruminant production. Thogoto virus which can be transmitted by Ixodid ticks has been associated with abortion storms in sheep, it may contribute to the large proportion of abortions which are due to unknown causes. Nairobi sheep disease is the most pathogenic virus disease known for sheep and goats in East Africa. Ganjam virus in India may ultimately be shown to be a significant cause of disease in small ruminants. Some unidentified Orbiviruses have been found both in ticks and sick sheep, and are thought to be a cause of some losses in African sheep and goats. Small ruminant populations in both Africa and Asia are vertebrate host for Congo-Crimean haemorrhagic fever, an important human pathogen, and for many Arboviruses some of which are of zoonotic importance.
