Geographic distribution and genetic diversity of the Ehrlichia sp. from Panola Mountain in Amblyomma americanum [PDF]

, 2008
Background: A novel Ehrlichia, closely related to Ehrlichia ruminantium, was recently discovered from Panola Mountain State Park, GA, USA. We conducted a study to determine if this agent was recently introduced into the United States.

Parasites & Vectors, 2012
Background In the Eastern and Upper Midwestern regions of North America, Ixodes scapularis (L.) is the most abundant tick species encountered by humans and the primary vector of B. burgdorferi, whereas in the southeastern region Amblyomma americanum (Say)

Assessing the underwater survival of two tick species, Amblyomma americanum and Amblyomma maculatum

Ticks and Tick-borne Diseases, 2019
The hard (ixodid) ticks Amblyomma americanum and Amblyomma maculatum are found throughout the southeastern United States. To study the effects of water inundation, which is an increasingly common phenomenon in many coastal areas, unfed adult A. americanum and A.

Vector competence of Amblyomma americanum (Acari: Ixodidae) for Rickettsia rickettsii [PDF]

Ticks and Tick-borne Diseases, 2017
Rickettsia rickettsii - the etiologic agent of Rocky Mountain spotted fever (RMSF) - is widely spread across the Americas. In the US, Dermacentor spp. ticks are identified as primary vectors of R. rickettsii and Rhipicephalus sanguineus s.l. has been implicated in transmission of this pathogen in several locations in the Southwest. Conversely, ticks of

Comparative population genetics of Amblyomma maculatum and Amblyomma americanum in the mid-Atlantic United States

Ticks and Tick-borne Diseases, 2021
The Gulf Coast tick, Amblyomma maculatum, is undergoing a northward expansion along the United States East Coast, most recently establishing populations in Virginia, Maryland, and Delaware. This expansion has human health implications, as A. maculatum is the primary natural vector of the bacterium Rickettsia parkeri, which causes a spotted fever-type ...

Identification of Residual Blood Proteins in Ticks by Mass Spectrometry Proteomics

Emerging Infectious Diseases, 2008
Mass spectrometry–based proteomics of individual ticks demonstrated persistence of mammalian host blood components, including α- and β-globin chains, histones, and mitochondrial enzymes, in Ixodes scapularis and Amblyomma americanum ticks for months ...

Ultrastructure of Haller's organ in the tick Amblyomma americanum (L.) [PDF]

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972
Haller's organ on the tarsus of the tick Amblyomma americanum (L.) (Acarina: Ixodidae; nymphal stage) was studied by scanning and transmission electron microscopy. It consists of a distal bristle group, (the “anterior pit”), and a proximal “capsule” which encloses several sensilla. The seven sensilla of the anterior pit (A1–A7) are all thick-walled and

Lethal Case of Bourbon Virus Leading to Shock and ECMO Utilization

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
We present a lethal case of Bourbon virus infection in a 63‐year‐old Caucasian, diabetic male who was previously in good health. The patient had spent time in the wooded areas of Bourbon County, Kansas, and removed three ticks from his body 5 days prior to presentation.
