| molecular characterization of sylvatic isolates of trichinella spiralis. | genetic relationships of 20 trichinella isolates from indiana wildlife were assessed and compared to trichinella isolated from an infected swine herd. trichinella larvae were isolated from coyotes, mink, raccoons, and red foxes. the larvae were maintained and amplified in white mice (icr) and wild mice (peromyscus leucopus). differences in phenotypic characters of sylvatic isolates in the 2 laboratory hosts included an approximately 10-30-fold increase in parasite fecundity in wild mice. dna for ... | 1989 | 2542508 |
| spread of ixodes scapularis (acari:ixodidae) in indiana: collections of adults in 1991-1994 and description of a borrelia burgdorferi-infected population. | collection records for the adult black legged tick, ixodes scapularis say, in indiana for the period 1991-1994 are presented and a new, established population of borrelia burgdorferi-infected i. scapularis is described. the number of i. scapularis adults collected in indiana increased progressively from 19 in 1991 to > 200 in 1994, and the number of indiana counties reporting at least 1 adult increased from 13 to 29. also, during this period, 4 countries in northwestern indiana yielded > 10 spec ... | 1996 | 8840696 |
| a small-scale survey of hantavirus in mammals from indiana. | in order to determine if hantaviruses were present in mice and other small mammals in indiana (usa), small mammals were trapped in brown, laporte, tippecanoe and whitley counties. sixty-seven small mammals were trapped during august and september 1994. sixty-three peromyscus leucopus, one microtus pennsylvanicus, one zapus hudsonius and two blarina brevicauda were captured and tested for hantaviruses. six p. leucopus were found to have antibody to sin nombre virus (sn) by igg elisa, and a 139 bp ... | 1997 | 9391967 |
