| dermatophilus congolensis infections in wildlife in new york state. | dermatophilus congolensis infection is described for the first time in a woodchuck (marmota monax) and a striped skunk (mephitis mephitis). this actinomycete was also recovered from a raccoon (procyon lotor) carcass which had been frozen for a year. encrusted lesions or denuded patches or both were seen during necropsy on the head, thorax, abdomen, and legs of each carcass. d. congolensis was demonstrated in strained smears or paraffin sections or both from the three animals and was recovered fr ... | 1981 | 7334073 |
| cryptosporidium parvum infection involving novel genotypes in wildlife from lower new york state. | cryptosporidium, an enteric parasite of humans and a wide range of other mammals, presents numerous challenges to the supply of safe drinking water. we performed a wildlife survey, focusing on white-tailed deer and small mammals, to assess whether they may serve as environmental sources of cryptosporidium. a pcr-based approach that permitted genetic characterization via sequence analysis was applied to wildlife fecal samples (n = 111) collected from september 1996 to july 1998 from three areas i ... | 2001 | 11229905 |
| increased recognition of powassan encephalitis in the united states, 1999-2005. | powassan virus (powv) disease is a rare human disease caused by a tick-borne encephalitis group flavivirus maintained in a transmission cycle between ixodes cookei and other ixodid ticks and small and medium-sized mammals. during 1958-1998, only 27 powv disease cases (mostly powassan encephalitis) were reported from eastern canada and the northeastern united states (average, 0.7 cases per year). during 1999-2005, nine cases (described herein) of serologically confirmed powv disease were reported ... | 2008 | 18959500 |
| potential role of deer tick virus in powassan encephalitis cases in lyme disease-endemic areas of new york, u.s.a. | powassan virus, a member of the tick-borne encephalitis group of flaviviruses, encompasses 2 lineages with separate enzootic cycles. the prototype lineage of powassan virus (powv) is principally maintained between ixodes cookei ticks and the groundhog (marmota momax) or striped skunk (mephitis mephitis), whereas the deer tick virus (dtv) lineage is believed to be maintained between ixodes scapularis ticks and the white-footed mouse (peromyscus leucopus). we report 14 cases of powassan encephalit ... | 2013 | 24274334 |
| host associations of ticks (acari: ixodidae) parasitizing medium-sized mammals in a lyme disease endemic area of southern new york. | ticks of eight medium-sized mammal species were studied in an area of endemic lyme disease in westchester county, n.y., from 1 april 1984 to 31 march 1985. most (81%) of the 266 total mammal captures were raccoon, procyon lotor (l.) (47%), opossum, didelphis virginiana (kerr) (19%), and striped skunk, mephitis mephitis schreber (15%); these host species accounted for 91% of the 1,519 ticks collected. although the total number of ticks was rather evenly distributed among these mammals, species co ... | 1989 | 2724317 |
| the role of medium-sized mammals as reservoirs of borrelia burgdorferi in southern new york. | the ability of raccoons (procyon lotor), striped skunks (mephitis mephitis) and opossums (didelphis virginiana) to serve as reservoirs of borrelia burgdorferi, the spirochetal agent of lyme disease, was compared with that of white-footed mice (peromyscus leucopus). twenty-eight (28) medium-sized mammals and 34 white-footed mice were captured in westchester county, new york (usa) in summer 1986. animals were caged over pans of water for 1 to 2 days to recover engorged tick larvae (ixodes dammini) ... | 1990 | 2388356 |
| isolation of deer tick virus (powassan virus, lineage ii) from ixodes scapularis and detection of antibody in vertebrate hosts sampled in the hudson valley, new york state. | deer tick virus, dtv, is a genetically and ecologically distinct lineage of powassan virus (powv) also known as lineage ii powv. human incidence of pow encephalitis has increased in the last 15 years potentially due to the emergence of dtv, particularly in the hudson valley of new york state. we initiated an extensive sampling campaign to determine whether powv was extant throughout the hudson valley in tick vectors and/or vertebrate hosts. | 2013 | 24016533 |
