Free-living birds, including migratory and non-migratory species, constitute an issue of major interest to many scientists and public because they can act as long-distance vectors for a wide range of microorganisms that could be transmissible to humans, animals, and poultry. The present study aimed to give a spotlight on the pathological affections that could be found in free flying resident pigeons (Columba livia var domestica) and their potential role in transmitting viral, bacterial and parasitic pathogens to various livestock in Egypt as well as to illustrate the zoonotic importance of this species of birds. The study was conducting on fifty apparently healthy wild pigeons collected from non-urban areas (6th of October city and 10th of Ramadan city) in Egypt during the period of the hunting season from September, 2015 to July, 2016. Birds were kept for 24hrs in the laboratory during which thorough clinical examination was carried out. After scarification; tracheal and cloacal swabs were collected as well as tissue specimens from various internal organs. The observed pathological lesions were numerous with variable incidences in different body organs; the prevalence and scoring of which were allocated. Bacteriological examination revealed isolation of E. coli O157, Klebsiella, Enterobacter, Citrobacter, Shigella and Pseudomonas as a single or as a mixed infection. While virological examination revealed isolation of H9N2 and PPMV-1 from all birds. It was concluded that wild pigeons could play an important role in transmitting some bacterial and viral pathogens to human, poultry farms and other live stocks.
