| vector potential and population dynamics for amblyomma inornatum. | we studied the natural life cycle of amblyomma inornatum and its vector potential in south texas. this tick is distributed throughout south texas and most of central america. a. inornatum represented 1.91% of the ticks collected by carbon dioxide traps during a study of free-living ticks in the tamaulipan biotic province in south texas. the life cycle of a. inornatum in south texas showed a clear seasonal pattern consistent with one generation per year. nymphs emerged in the spring with a peak i ... | 2015 | 25881916 |
| 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 |
| molecular detection of bacteria in the families rickettsiaceae and anaplasmataceae in northern crested caracaras (caracara cheriway). | bacterial pathogens of the families anaplasmataceae and rickettsiaceae are often spread to humans or other animals from bites from infected arthropod hosts. recently, an increasing number of studies have implicated migratory birds in the circulation of these pathogens through the spread of arthropod vectors. however, few studies have examined the potential for resident bird populations to serve as reservoirs for these zoonoses. in this study, we used nested pcrs of the groesl and 17 kda genes to ... | 2016 | 26837860 |
