| gulf coast ticks (amblyomma maculatum) and rickettsia parkeri, united states. | geographic distribution of rickettsia parkeri in its us tick vector, amblyomma maculatum, was evaluated by pcr. r. parkeri was detected in ticks from florida, georgia, kentucky, mississippi, oklahoma, and south carolina, which suggests that a. maculatum may be responsible for additional cases of r. parkeri rickettsiosis throughout much of its us range. | 2007 | 17553257 |
| rickettsia parkeri rickettsiosis and its clinical distinction from rocky mountain spotted fever. | rickettsia parkeri rickettsiosis, a recently identified spotted fever transmitted by the gulf coast tick (amblyomma maculatum), was first described in 2004. we summarize the clinical and epidemiological features of 12 patients in the united states with confirmed or probable disease attributable to r. parkeri and comment on distinctions between r. parkeri rickettsiosis and other united states rickettsioses. | 2008 | 18808353 |
| ticks and tick-borne pathogens and putative symbionts of black bears (ursus americanus floridanus) from georgia and florida. | ticks were collected from 38 black bears (ursus americanus floridanus) from northwestern florida (n = 18) from 2003 to 2005 and southern georgia (n = 20) in 2006. five species (amblyomma americanum, a. maculatum, dermacentor variabilis, ixodes scapularis, and i. affinis) were collected from florida bears, and 4 species (a. americanum, a. maculatum, d. variabilis, i. scapularis) were collected from bears in georgia. ixodes scapularis was the most frequently collected tick, followed by d. variabil ... | 2009 | 19413369 |
| rickettsia parkeri in amblyomma americanum ticks, tennessee and georgia, usa. | to determine the geographic distribution of the newly recognized human pathogen rickettsia parkeri, we looked for this organism in ticks from tennessee and georgia, usa. using pcr and sequence analysis, we identified r. parkeri in 2 amblyomma americanum ticks. this rickettsiosis may be underdiagnosed in the eastern united states. | 2009 | 19788817 |
