| concurrent capillaria and heterakis infections in zoo rock partridges, alectoris graeca. | two adult rock partridges raised in a city zoo were examined parasitologically and pathologically. two distinctive eggs resembling those of capillaria and heterakis were detected in the feces. at necropsy, a markedly-dilated duodenum with severe catarrhal exudates, containing adult worms of capillaria sp. and heterakis sp. in the cecum, was observed. male capillaria had the cloacal aperture extended almost terminally with a small bursal lobe and an unsheathed spicule with transverse folds withou ... | 2010 | 20877506 |
| intensity of nematode infections in cyclic and non-cyclic rock partridge (alectoris graeca saxatilis) populations. | populations of rock partridge (alectoris graeca saxatilis), in the trentino province of italy, exhibit cyclic fluctuations in abundance associated with relatively dry habitat. one of the hypothesis to explain these cycles is that survival of some free living parasitic stages and rates of infection are greater in these areas leading to higher parasite burden. this hypothesis was examined by investigating the intensity of parasite infection in cyclic and non cyclic rock partridge populations. anal ... | 1999 | 10870561 |
