Clinical coccidiosis in raccoons (Procyon lotor).
Clinical coccidiosis was diagnosed in wild-caught and captive raccoons. Eimeria procyonis-like oocysts were seen in 15 of 15 captive raccoons. In 6 of 6 juvenile wild-caught raccoons examined at necropsy, endogenous coccidian stages were seen in the small intestine. Two types of schizonts (large and small) were identified. Large schizonts were up to 110 microm long, contained 10-microm-long mer...
متن کاملSpontaneous idiopathic arteritis of the testicular artery in raccoons (Procyon lotor).
The testes and the spermatic cord of raccoons (Procyon lotor, kits to adult breeders; n = 48) were examined. Segmental arteritis confined to the extratesticular portions of the testicular artery was present in raccoons of all ages. The arterial changes were seen in laboratory-confined experimental and control animals as well as in wild-caught raccoons. The lesions consisted of proliferative end...
متن کاملExperimental infection of raccoons (Procyon lotor) with West Nile virus.
To characterize the responses of raccoons to West Nile virus (WNV) infection, we subcutaneously exposed them to WNV. Moderately high viremia titers (≤ 10(4.6) plaque forming units [PFU]/mL of serum) were noted in select individuals; however, peak viremia titers were variable and viremia was detectable in some individuals as late as 10 days post-inoculation (DPI). In addition, fecal shedding was...
متن کاملSeasonal changes in spermatogenesis and peripheral testosterone concentration in raccoons (Procyon lotor) in Hokkaido.
Feral raccoons (Procyon lotor) have been increasing in number since 1979 and are currently subject to pest control in Hokkaido. One of the reasons for the increase in numbers is thought to be the high reproductive potential of raccoons, but little is known about their reproduction. The main aim of this study was to clarify seasonal changes in spermatogenesis and peripheral testosterone concentr...
متن کاملNeuroaxonal dystrophy in raccoons (Procyon lotor) from Iowa.
During a 12-month period (1998-1999), microscopic evidence of neuroaxonal dystrophy (NAD) in medullae oblongata of raccoons (Procyon lotor) was observed in 17/39 (47% prevalence in adults) from Iowa, USA. Three of the animals were kits (<3 months), 26 were between 1 and 2 years, and 10 were over 7 years. Lesions were not seen in the medullae of the 3 kits. In young adults, the lesions were mild...
