| serologic survey of selected zoonotic disease agents in black-tailed jack rabbits from western texas. | a serologic survey for the agents of rocky mountain spotted fever (rmsf) (rickettsia rickettsii), borrelia spp. including the causative agent for lyme disease (borrelia burgdorferi), and plague (yersinia pestis) was conducted on blood samples collected from 30 and 46 black-tailed jack rabbits (lepus californicus) from an urban environment in lubbock, texas (usa) during winter 1987 and the following spring 1988, respectively. antibody titers to the agents of rmsf and borreliosis were detected in ... | 1990 | 2106044 |

| parasites and selected diseases of collared peccaries (tayassu tajacu) in the trans-pecos region of texas. | fifty-five collared peccaries (tayassu tajacu) were collected from october 1988 through april 1991 from five counties within the trans-pecos region of texas (usa) to monitor for diseases and parasites. no endoparasites were recovered on gross examination. antibody to borrelia burgdorferi was documented in one (2%) of 55 specimens. three (6%) of 54 collared peccaries were positive for yersinia pestis antibodies. all collared peccaries were negative for antibodies against brucella spp., francisell ... | 1996 | 8827690 |
| murine typhus in children, south texas. | children from south texas were evaluated for immunoglobulin g to rickettsia typhi, the causative agent of murine typhus. of 513 children, 8.6% of those 1-5 years of age, 13.3% of those 6-11 years of age, and 13.8% of those 12-17 years of age had positive results. | 2007 | 17553239 |
| the expanding spectrum of eschar-associated rickettsioses in the united states. | until recently, rickettsia rickettsii was the only substantiated cause of tick-borne spotted fever group (sfg) rickettsiosis in humans in the united states. rickettsia parkeri, originally thought to be nonpathogenic in humans, was recently proved to be another cause of tick-borne sfg rickettsiosis. | 2010 | 20404224 |
| prevalence of antibodies to spotted fever group rickettsia spp. and ehrlichia spp. in coyotes (canis latrans) in oklahoma and texas, usa. | coyotes (canis latrans) are commonly infested with ticks, including amblyomma americanum, the predominant vector of ehrlichia chaffeensis and ehrlichia ewingii; dermacentor variabilis, an important vector of rickettsia rickettsii; and amblyomma maculatum, a major vector of rickettsia parkeri, a spotted fever group (sfg) rickettsia. to determine the degree to which coyotes are infected with or exposed to tick-borne bacterial disease agents, serum samples collected from coyotes in oklahoma and tex ... | 2013 | 23778619 |
| modelling spatial concordance between rocky mountain spotted fever disease incidence and habitat probability of its vector dermacentor variabilis (american dog tick). | the spatial distribution of dermacentor variabilis, the most commonly identified vector of the bacterium rickettsia rickettsii which causes rocky mountain spotted fever (rmsf) in humans, and the spatial distribution of rmsf, have not been previously studied in the south central united states of america, particularly in texas. from an epidemiological perspective, one would tend to hypothesise that there would be a high degree of spatial concordance between the habitat suitability for the tick and ... | 2012 | 23242684 |
