Recent research into the nature and significance of rheumatoid serum factors has been largely immunological and biochemical. The epidemiology of these components is virtually unknown. During recent years we have had the opportunity of studying several population samples, and data from these surveys have now been gathered and are presented with particular reference to the epidemiology of the ser...

THE sheep population of Australia now exceeds 130 million, spread over the greater part of the Commonwealth and grazing under a wide variety of climatic and nutritional conditions. In some areas, sheep may have to exist for long periods on dry native pastures or be fed supplementary rations, both of which can be low in carotene, the precursor of Vitamin A.

The serological prevalence of Q fever in Mexico is unknown. A serological survey for Coxiella burnetii was undertaken on a randomly selected population of dairy cattle, beef cattle, goats and sheep flocks. Serological examination of animal sera for antibodies against Coxiella burnetii was carried out by the ELISA technique. The 28% of the dairy cattle and 10% of beef cattle examinated were anti...

Association of genetic polymorphism in the calpastatin (CAST) gene with average daily gain was examined in Iranian purebred Kurdi sheep. The genotypes for CAST were determined by the PCR-SSCP method. Blood samples were collected from 84 purebred Kurdi sheep belonging to the Kurdi Breeding Station located in the Khorasan province, north-east of Iran. Extraction of genomic DNA was based on the Gu...
