In a survey of 1, 191 fresh and dry sheep-skins from Kenya, Uganda, Tanzania and Ethiopia the variety and prevalence of skin diseases in all four countries were about the same. In descending order of frequency the following diseases were found: demodicosis (13.3%), streptothricosis (2.2%), sheep pox (0.9%), ringworm due to Trichophyton (0.4%), psoroptic mange (0.2%), seborrhoea sicca (0.2%) and sarcoptic mange (0.1%). Two important P.M. defects were putrefaction (3.5%) and insect damage (3.2%). A comparison with data published previously in cattle and goats [see V.B. 40, abst. 4958] showed that cattle and goats had an equally high susceptibility to skin diseases whereas sheep were relatively resistant.
