Abstract

Avian encephalomyelitis (AE) is a viral disease of poultry. Although the disease has a milder clinical course in turkeys than in chickens, reproductive flocks of turkeys are vaccinated against AE. Commercial AE ELISA kits are specifically designed for chickens, which makes it difficult to implement these tests in serological monitoring of turkey flocks. The aim of the study was to compare the AE serological results provided by two ELISA kits from different producers when testing an AE-vaccinated flock of turkey hens and their progeny. We detected differences in the sensitivity of the ELISAs for testing specific anti-AE antibody levels in turkey serum samples.

Abstract

Transmissible Viral Proventriculitis (TVP) is a disease of chickens which contributes to significant production losses. Recent reports indicate the role of chicken proventricular necrosis virus (CPNV) in the development of TVP. However, the relationship between CPNV and TVP is inconclusive and it has been addressed in just a few reports.
Given the above, a study was conducted to identify the relationship between TVP and CPNV prevalence in broiler chickens in Poland.
The study was carried out on 35 proventriculi samples sent for histopathological (HP) examination to the Faculty of Veterinary Medicine in Olsztyn between 2017 and 2019. After HP examination, TVP positive samples were processed for CPNV identification by RT-PCR. TVP was the most common pathological condition of proventriculi (23 cases). CPNV was identified in 10 out of those 23 cases. The average HP score, and the average necrosis and infiltration score for CPNV-positive samples was significantly higher than in CPNV-negative ones. The average age of the CPNV-positive chickens was significantly lower than in CPNV-negative birds.
Our study confirms the role of CPNV in TVP pathogenesis and it seems that preservation of the proventriculi in the early stages of the disease, when the lesions are more pronounced, should result in a greater probability of CPNV detection.
