title: Incidence of brucellosis in domestic livestock in Saudi Arabia.
abstract: The results of an extensive serological survey for brucellosis antibodies using the standard plate agglutination procedure on 14,000 serum samples from native domestic animals and imported livestock over a five year period are reported. The incidence of brucellosis was highest (11.6%) in small ruminants reared intensively in breeding establishments, next highest (2.6%) in imported animals sacrificed during the Hajj season of 1977 and somewhat lower (1.5%) in local livestock sacrificed during the same Hajj season. The incidence was very low among the following groups of livestock: small ruminants raised on desert ranges (0.5%), small ruminants raised in small groups around individual homes (0.4%) and in commercial dairy herds (0.2%).
