Highlights

• Substantial increase in diagnostic submissions received by the VLA compared with the same time last year. This may be a reflection of improving financial and economic conditions.
• Avirulent avian paramyxovirus type 1 (APMV-1) and H2N3 LPAI isolated from a flock of free-range broilers. A routine scanning surveillance submission yielded an APMV-1 isolate. Follow up statutory disease investigations unusually resulted in the additional identification of an H2N3 LPAI virus. Wild birds were suspected to be the source.
• Emergent H5N1 HPNAI genotype circulating in poultry and wild birds in Eurasia. Romania and Bulgaria are the only EU Member States to report detections so far this year. Vigilance for suspect disease required.
• First detection of IBV European QX-like strains in commercial poultry. Previously only found in backyard poultry flocks in Great Britain.
• Chick anaemia, transmissible viral proventriculitis and Marek's disease amongst other infectious diseases affecting commercial poultry. Such diseases vary in frequency but are economically important. Where available, prevention by vaccination is widely practised.
• Further diagnosis of ORT as part of respiratory disease complex in pheasants. ORT and APMV-2 co-infection reported last quarter.
