Changes in Disease Patterns and Risk Factors


Orchitis and weight loss were the presenting signs in a boar with tuberculosis with a likely two-year incubation period. A sow on the same unit also had Tb but showed no clinical signs.

Two unusual aetiologies of abortion were detected and were caused by Actinomyces hyovaginalis and Actinobacillus rossii but were not of zoonotic significance or a significant potential treat to the wider pig population.

The further detection of strains of Brachyspira hyodysenteriae resistant to antimicrobials, is of concern for the health and welfare of the breeding herd in the UK.

Pandemic H1N1 influenza virus continues to be detected.

There is no evidence of the emergence of post weaning cachexic syndrome or high mortality neonatal enteritis as reported in other countries.

The investigation continues into the cause of circulatory failure and 22 per cent mortality in neonatal pigs on one farm.
