Scientific update


A serious case of selenium toxicity is reported which resulted in many paralysed pigs but where the food chain was protected.

A case of necrotising rhinitis, tonsillitis and necrotising hepatitis not inconsistent with Aujeszky's disease was investigated and once this Notifiable Disease was eliminated, it was demonstrated that lesions seen were due to PCV2-associated disease.

The continued low incidence of PMWS and PCV2-associated disease is reported and thought to be directly related to the introduction of PCV2 vaccines.

PRRS remains the most important disease of pigs in Great Britain, with concerns that an American vaccine-derived strain may be introduced into the UK via weaners.

The incidence of swine dysentery continues to rise and is of major concern, given that during 2008 and 2009 multiple resistant strains of Brachyspira hyodysenteriae were identified.
