epidemiology of canine leishmaniasis: a comparative serological study of dogs and foxes in amazon brazil.the paper describes a longitudinal field study of canine leishmaniasis in sympatric domestic dog and crab-eating fox (cerdocyon thous) populations. dogs were studied in house-to-house surveys, and foxes were studied by live-trapping and radio-telemetry. because serological tests (ifat in this case) for leishmaniasis are often of uncertain sensitivity and specificity, we draw conclusions comparatively. both cross-sectional (age-prevalence) and longitudinal analyses indicate that incidence in dogs ...19947970884
contact rates between wild and domestic canids: no evidence of parvovirus or canine distemper virus in crab-eating foxes.evaluating the risk of disease spill-over from domestic dogs to wildlife depends on knowledge of inter-specific contact rates and/or exposure to aetiological agents in dog environments. here, contact rates of crab-eating foxes (cerdocyon thous) with sympatric domestic dog populations were measured over 25months in amazon brazil. foxes and dogs were serologically and clinically monitored for exposure to canine parvovirus (cpv-2) and canine distemper virus (cdv), pathogens known to have caused wil ...200111356314
low infectiousness of a wildlife host of leishmania infantum: the crab-eating fox is not important for transmission.the epidemiological role of the crab-eating fox cerdocyon thous in the transmission of leishmania infantum is assessed in a longitudinal study in amazon brazil. a total of 37 wild-caught foxes were immunologically and clinically monitored, and 26 foxes exposed to laboratory colonies of the sandfly vector lutzomyia longipalpis, over a 15-month period. in total 78% (29/37) of foxes were seropositive for anti-leishmania igg on at least 1 occasion, and 38% (8/37) had infections confirmed by pcr and/ ...200212458824
ticks (acari: ixodida) on wild carnivores in brazil.the present study reports field data of ticks infesting wild carnivores captured from july 1998 to september 2004 in brazil. additional data were obtained from one tick collection and from previous published data of ticks on carnivores in brazil. during field work, a total of 3437 ticks were collected from 89 cerdocyon thous (crab-eating fox), 58 chrysocyon brachyurus (maned wolf), 30 puma concolor (puma), 26 panthera onca (jaguar), 12 procyon cancrivorus (crab-eating raccoon), 4 speothos venati ...200516082932
