Salmonella in sewage effluent and the relationship to animal and human disease in the north of Scotland.

During the period July 1982 to December 1984, the presence of salmonella organisms was investigated at weekly intervals in the sewage system and abattoir effluent of a town in the north of Scotland. Three hundred and fifteen isolations, representing 37 different serotypes, were made which included 20 different Salmonella typhimurium phage types and four different S enteritidis phage types. Ten of the serotypes were isolated from livestock in the district during the survey as well as in the periods immediately before and after the survey. There were seven recorded incidents of human infection, involving four salmonella serotypes, only three of which were isolated concurrently from sewage.

A survey of sheep losses and their causes on commercial farms in the north of Scotland.

A three year survey on sheep deaths and their causes was conducted on 10 commercial farms in the north of Scotland. Diseases and other trauma associated with the perinatal period accounted for 56.81% of all ewe deaths, while pneumonia, parasitic gastroenteritis, torsion of the bowel and haemorrhagic enteritis (redgut) accounted for a further 21.7%. No one disease condition predominated in the rams and hoggs. In lambs, most deaths occurred between birth and four days old (77.86%). Causes came in the form of starvation and exposure (34.2%), stillbirths (18.2%), lambing injuries (11.06%), infectious conditions (8.0%), dystocia (7.6%) and abortion (5.2%). The overall death rate among the lambs was 14.2%.

The association of non-clotting of cow's milk with scour in the single suckled beef calf.

An apparent correlation between the clotting ability of cows milk and the prevalence of scour in suckling calves was investigated. Fifty-eight per cent of the milk samples of mothers of scouring single suckled calves showed impaired clotting ability. While the cause of this remains unknown there appears to be a link with diet. The poor clotting ability is probably a contributory factor in the aetiology of scour in the suckler calf, as the abnormality has only been seen in the milk from mothers of scouring calves.
