| 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 |
| agents of human anaplasmosis and lyme disease at camp ripley, minnesota. | the transmission dynamics of anaplasma phagocytophilum (ap) and borrelia burgdorferi (bb) among ixodes scapularis (is) and mammalian hosts was investigated at camp ripley, an area representative of central minnesota. prevalence of white-footed mouse infection with ap and bb were 20% and 42%, respectively, with a coinfection level of 14%. peak levels of infection with both agents occurred in may. the average levels of seropositivity to ap and bb were 29.3% and 48%, respectively. of the mice infec ... | 2011 | 21867420 |
| reservoir competence of wildlife host species for babesia microti. | human babesiosis is an increasing health concern in the northeastern united states, where the causal agent, babesia microti, is spread through the bite of infected ixodes scapularis ticks. we sampled 10 mammal and 4 bird species within a vertebrate host community in southeastern new york to quantify reservoir competence (mean percentage of ticks infected by an individual host) using real-time pcr. we found reservoir competence levels >17% in white-footed mice (peromyscus leucopus), raccoons (pro ... | 2012 | 23171673 |
| an experimental test of competition among mice, chipmunks, and squirrels in deciduous forest fragments. | mixed hardwood forests of the northeast united states support a guild of granivorous/omnivorous rodents including gray squirrels (sciurus carolinensis), eastern chipmunks (tamias striatus), and white-footed mice (peromyscus leucopus). these species coincide geographically, co-occur locally, and consume similar food resources. despite their idiosyncratic responses to landscape and patch variables, patch occupancy models suggest that competition may influence their respective distributions and abu ... | 2013 | 23824654 |
| intraerythrocytic parasites in rodent populations of connecticut: babesia and grahamella species. | a total of 612 peromyscus leucopus, 11 microtus pennsylvanicus, 21 clethrionomys gapperi, and 4 tamias striatus was collected in connecticut and examined for babesia and grahamella during 1976 and 1977. babesia antibodies were detected in sera of 9 p. leucopus collected from 4 sites. babesia parasites were not detected in the blood smears of captured rodents. subsequent splenectomy and subinoculation of blood from these rodents into susceptible animals failed to induce disease and no babesia was ... | 1979 | 512755 |
