| ectoparasites of opossums and raccoons in southeastern georgia. | twelve species of ectoparasites (four fleas, three ticks, three chiggers, one macronyssid mite, and one atopomelid mite) were recovered from 42 opossums, didelphis virginiana kerr, live-trapped from september 1992 through april 1994 in southeastern georgia. the fleas, ctenocephalides felis (bouché) (prevalence = 19%) and polygenis gwyni (c. fox) (36%); the ticks, dermacentor variabilis (say) (40%) and ixodes scapularis say (19%); and the macronyssid mite, ornithonyssus wernecki (fonseca) (21%), ... | 1994 | 7815408 |
| differential effects of experimental increases in sociality on ectoparasites of free-ranging raccoons. | 1. parasite transmission depends on the rate at which hosts come into contact with one another or the infectious stages of parasites. however, host contact rates and their influence on parasite transmission are difficult to quantify in natural settings and can fluctuate with host behaviour and the ecological constraints of parasites. 2. we investigated how experimental increases in rates of contact and social aggregation affected ectoparasite prevalence and intensity of free-ranging raccoons (pr ... | 2010 | 20148994 |
| arthropods (acari, mallophaga, siphonaptera) collected from procyon lotor (linnaeus, 1758) (mammalia, carnivora, procyonidae) in poland. | from 9 specimens of procyon lotor collected in vicinity of dobroszyn and górzyca (lubuskie province) 61 arthropods of 6 species were obtained: siphonaptera (one specimen), acari (3 species), phthiraptera (one specimen--trichodectes octomaculatus; new species to fauna of poland) and one specimen of psocoptera. | 2009 | 19579787 |
| relative importance of demographics, locale, and seasonality underlying louse and flea parasitism of raccoons (procyon lotor). | a variety of demographic, seasonal, and site-specific variables may influence parasitism, but the relative importance of these variables is generally unclear. we measured the relative ability of host characteristics, season, and site to explain louse (trichodectes octomaculatus) and flea (orchopeas howardi) infestation across 10 populations of raccoons (procyon lotor). lice are highly dependent on specific hosts and are predicted to display a relatively strong relationship with factors intrinsic ... | 2009 | 18578574 |
| health survey of free-ranging raccoons (procyon lotor) in central park, new york, new york, usa: implications for human and domestic animal health. | we conducted health assessments on 113 free-ranging raccoons ( procyon lotor ) in central park, new york city, us, in february 2010, september 2010, and november 2011 in conjunction with a trap-vaccinate-release program to control a raccoon rabies epizootic. five individuals were sampled at two time points for 118 raccoon examinations in total. we tested 13 of 13 and 8 of 13 euthanized raccoons for rabies and canine distemper virus (cdv), respectively, by antigen testing on brain tissue; all wer ... | 2017 | 28135131 |
| the effect and relative importance of neutral genetic diversity for predicting parasitism varies across parasite taxa. | understanding factors that determine heterogeneity in levels of parasitism across individuals is a major challenge in disease ecology. it is known that genetic makeup plays an important role in infection likelihood, but the mechanism remains unclear as does its relative importance when compared to other factors. we analyzed relationships between genetic diversity and macroparasites in outbred, free-ranging populations of raccoons (procyon lotor). we measured heterozygosity at 14 microsatellite l ... | 2012 | 23049796 |
