Histopathological Changes In The Intestine Of Infected Pigeons (Columba Livia Domestica) Caused By Helminthes Infection From Al-Qassim, Saudi Arabia

Helminthes infection causes extensive harm to the pigeon host. The purpose of this study was to observe histopathological changes caused by helminths infection. Thirty-five pigeons (C.L. domestica) were purchased weekly from a birds market from Al-Qassim region, Saudi Arabia. Out of the 35 pigeons examined, 9 pigeons (25.71%) were found infected with helminth parasites, which were identified as one cestode (Raillietina sp.), and one nematode (Ascaridia columbae). The infected pigeons suffered from growth retardation, emaciation, weakness, droopiness, and diarrhea. A lot of histopathological changes were seen in the intestine of infected pigeons including atrophy and distortion of villi, infiltration of inflammatory lymphocytic cells, erosion, and loss of the typical structure of the intestine, necrosis in villi, and blood vessels congestion. This study concludes, for the first time in AL-Qassim region-Saudi Arabia, that the infection with helminth parasites caused significant histopathological changes in the intestines of the infected pigeons, and this could lead to increased mortality to the infected pigeons. Further work is necessary in Saudi Arabia to determine the prevalence and biological factors that have a significant impact on the helminth parasites community.
