The first isolations of Campylobacter mucosalis in South Africa are described. Isolations were made from a 6-week-old weaner pig with necrotic enteritis and from 2 gingival swabs of suckling piglets from herds with histories of porcine intestinal adenomatosis. The isolates were serologically identified as being serotype A strains.
A mycetoma like syndrome in a dog caused by a hyphomycete reminiscent of Acremonium hyalinum (Sacc.) W. Gams, is described. The organism was seen in smears of pus and sections from the kidneys and myocardium and was isolated in pure culture from the lesions.
The overriding economic importance of reproductive efficiency to successful pig production makes it necessary to collect and analyse performance records for the diagnosis and control of reproductive failure. Recently published production standards from the United Kingdom are related to the results obtained from 68 herds in the National Pig Health Scheme. It is concluded that more attention to the managerial aspects of weaning and rebreeding will do much to improve farrowing frequency.
