| Abstract: | A total of 165 adult feral pigeons (Columba livia) were captured in 7 different parks of the municipality of Murcia, Southeastern Spain. Birds were evaluated clinically and subsequently necropsied. All birds appeared to be in good physical condition and no apparent signs of disease were observed. However, 17.6% of the pigeons were parasitized by Tetrameres (Petrowimeres) fissispina. The nematode burden in the proventriculus ranges from 5 to 64 specimens (median: 19); the median of female and male nematodes was 17 (range: 4–54) and 3 (range: 0–12), respectively. Despite the absence of detectable signs of disease, lesions induced by T. (P.) fissispina were evident. The histopathologic analysis revealed a pressure atrophy of the proventricular glands and a light inflammatory infiltrate surrounding the papillae. Pigeons captured in parks with soil had significantly higher T. (P.) fissispina prevalence compared with those captured in paved areas. |
