Abstract |
: |
Pigeons are a member of birds that live side by side with humans. This study aimed to identify helminth parasites infecting the domestic pigeons in Al-Qassim region, Saudi Arabia, and the biological factors possibly affecting the prevalence of infection. Also, study the biochemical and histopathological changes caused by helminths infection on infected pigeons' tissues. A total of (354) pigeons (C. L. domestica) were purchased randomly from four cities in Al-Qassim region: Buraydah, Unaizah, Ar Rass, and Al-Bukairiyah, during the period from January to December 2021, and examined to determine the helminths prevalence, and the relationship between the infection and the biological factors (city, season, gender, age, and weight). The overall prevalence rate of helminths was (50%). More precisely, (31.6%) of pigeons were infected with cestodes, (13.3%) with nematodes, and (5.1%) with mixed infection (both cestodes and nematodes). No trematodes were recorded in this study. Our results revealed that some biological factors played a significant role in helminths infection. The morphological characterization using (Light and scanning electron microscopes) revealed that cestodes belong to (Raillietina sp.), while nematodes belong to (Ascaridia columbae). The molecular analysis confirmed the taxonomy of these parasites based on their morphology. All the genetic sequences obtained in this study were deposited in GenBank, and this may be the first time for A. columbae-Cox-1 gene to be submitted to GenBank from Saudi Arabia. The biochemical analysis of infected pigeons' muscles showed a remarkable decrease in protein and lipid levels, while a high increase in carbohydrate level compared to uninfected ones. Several histopathological alterations were observed in infected pigeons' intestines including atrophy and distortion of villi and glands, losing the typical structure of intestine, infiltration of inflammatory lymphocytic cells, blood vessel congestion. |
