pathology and epidemiology of ceruminous gland tumors among endangered santa catalina island foxes (urocyon littoralis catalinae) in the channel islands, usa.in this study, we examined the prevalence, pathology, and epidemiology of tumors in free-ranging island foxes occurring on three islands in the california channel islands, usa. we found a remarkably high prevalence of ceruminous gland tumors in endangered foxes (urocyon littoralis catalinae) occurring on santa catalina island (sca)--48.9% of the dead foxes examined from 2001-2008 had tumors in their ears, and tumors were found in 52.2% of randomly-selected mature (≥ 4 years) foxes captured in 20 ...201526618759
a suspected canine distemper epidemic as the cause of a catastrophic decline in santa catalina island foxes (urocyon littoralis catalinae).the island fox (urocyon littoralis catalinae) population on santa catalina island, california, usa declined precipitously in 1999 with an approximate 95% reduction on their eastern range, an area representing 87% of the island. during this investigation, between october 1999 and april 2000, evidence of live foxes dramatically decreased. the only carcass recovered during the decline succumbed to a co-infection of canine distemper virus (cdv) and toxoplasmosis. sequence analysis of the viral p gen ...200919395743
ear mite removal in the santa catalina island fox (urocyon littoralis catalinae): controlling risk factors for cancer development.ear mites (otodectes cynotis) and ear canal tumors are highly prevalent among federally endangered island foxes (urocyon littoralis catalinae) living on santa catalina island off the coast of southern california. since studies began in the 1990s, nearly all foxes examined were found to be infected with ear mites, and ceruminous gland tumors (carcinomas and adenomas) were detected in approximately half of all foxes ≥ 4 years of age. we hypothesized that reduction of ear mite infection would reduc ...201526641820
