Morphological and molecular characterization of Ascaridia columbae in the domestic pigeon (Columba livia domestica) and the assessment of its immunological responses.

ABSTRACT: Parasitism is a divesting problem that is frequently overlooked and may result in severe prominent clinical manifestation. This study aimed to investigate the seasonal and sexual prevalence of the gastrointestinal nematode Ascaridia columbae (A. columbae) infection among domestic pigeons in Giza governorate, Egypt, during the period from 2020 to 2021. One hundred and sixty suspected pigeons were clinically investigated. Blood & tissue samples were collected from infected birds to estimate serum zinc concentration, malondialdehyde (MDA), and nitric oxide levels. As well as tumor necrosis factor-alpha (TNF-α), interleukin 1β (IL1β) activity, and histopathological examination were estimated; also, worms were collected for morphological identification using electron microscope (SEM) and molecu
