| black creek canal virus infection in sigmodon hispidus in southern florida. | a total of 1,500 small mammals were collected and tested for antibodies cross-reactive to sin nombre virus (hantavirus: bunyaviridae) at 89 sites in a 1,600 km2 study area of southern florida. more than 95% of the 123 seropositive animals were cotton rats (sigmodon hispidus), suggesting infection by black creek canal virus, although seroreactive rattus rattus (5 of 294) and peromyscus gossypinus (1 of 39) also were captured. crude seroprevalence in s. hispidus was 11%. seroprevalence increased w ... | 1998 | 9840584 |
| antibodies to granulocytic ehrlichiae in white-footed and cotton mice in eastern united states. | serum samples, collected from peromyscus leucopus (white-footed mouse) or peromyscus gossypinus (cotton mouse) during 1987 through 1990 in florida, georgia, maryland, mississippi, and north carolina (usa), and in 1997 in southern connecticut were analyzed by indirect fluorescent antibody (ifa) staining methods or western blot procedures for antibodies to granulocytic ehrlichiae. of the 82 sera from white-footed mice in connecticut tested by ifa methods with either the bds or nch-1 strain of the ... | 1999 | 10231752 |
| rodent ectoparasites from two locations in northwestern florida. | from feb.-apr. 1999, 19 species of ectoparasitic arthropods (2 sucking lice, 4 fleas, 4 ticks, 2 mesostigmatid mites, 5 chiggers, 2 fur mites) were recovered from 106 rodents belonging to 5 species (cotton mouse, peromyscus gossypinus, n = 64; cotton rat, sigmodon hispidus, n = 23; eastern woodrat, neotoma floridana, n = 9; golden mouse, ochrotomys nuttalli, n = 9; eastern gray squirrel, sciurus carolinensis, n = 1) at tall timbers research station, leon county, florida. during the same period, ... | 2000 | 11217221 |
| genetic heterogeneity of borrelia burgdorferi sensu lato in the southern united states based on restriction fragment length polymorphism and sequence analysis. | fifty-six strains of borrelia burgdorferi sensu lato, isolated from ticks and vertebrate animals in missouri, south carolina, georgia, florida, and texas, were identified and characterized by pcr-restriction fragment length polymorphism (rflp) analysis of rrf (5s)-rrl (23s) intergenic spacer amplicons. a total of 241 to 258 bp of intergenic spacers between tandemly duplicated rrf (5s) and rrl (23s) was amplified by pcr. msei and drai restriction fragment polymorphisms were used to analyze these ... | 2001 | 11427560 |
| borrelia species in host-seeking ticks and small mammals in northern florida. | the aim of this study was to improve understanding of several factors related to the ecology and environmental risk of borrelia infection in northern florida. small mammals and host-seeking adult ticks were collected at several sites, and specimens were tested for the presence of borrelia species, primarily by pcr amplification. tissues from some vertebrates and ticks were initially cultured in bsk-h medium to isolate spirochetes, but none were recovered. however, comparison of partial flagellin ... | 2004 | 15528699 |
| amblyomma auricularium (ixodida: ixodidae) in florida: new hosts and distribution records. | previous published evidence for the occurrence of an exotic armadillo tick, amblyomma auricularium (conil), in florida is scant, but we found it is fully established and integrated into the state's tick fauna. we collected 11,192 specimens of this tick from naturalized nine-banded armadillos, dasypus novemcinctus l., and 14 other species of wild native mammals and birds in florida, while sampling statewide during 2004 through 2007. in all, we document its specific presence only in 14 contiguous ... | 2017 | 28082640 |
