This study investigated the prevalence of inclusion body hepatitis (IBH) infections during the past five years (2010-2014) in broiler chicken flocks in Poland. The diagnosis of IBH was based on anatomopathological investigations and histopathological analyzes. IBH was the most prevalent disease in broiler flocks in Poland (10.4%) during this time period, and occurred as a primary infection. The fewest cases of IBH occurred in the summer, suggesting that the temperature may have been a possible stressor that increased susceptibility to IBH. However, over the last 5 years the occurrence of clinical IBH cases in Poland has systematically decreased.
本研究调查了过去五年（2010 - 2014年）波兰肉鸡群中包涵体肝炎（IBH）感染的流行情况。IBH的诊断基于解剖病理学调查和组织病理学分析。在此期间，IBH是波兰肉鸡群中最普遍的疾病（10.4%），并且作为原发性感染出现。IBH病例在夏季最少，这表明温度可能是增加对IBH易感性的一个潜在应激源。然而，在过去5年中，波兰临床IBH病例的发生呈系统性下降。
