SURVEY OF Rickettsia spp. IN TICKS IN NACOGDOCHES COUNTY, TEXAS
<p><em>Rickettsia parkeri </em>is an obligate intracellular pathogenic bacterium that is commonly transmitted by the Gulf Coast tick, <em>Amblyomma maculatum</em>. <em>Rickettsia parkeri</em> is the causative agent of <em>Rickettsia parkeri </em>rickettsiosis, which is a disease characterized by …

Interação funcional, expressão de genes e filogenia entre proteínas de membrana de Rickettsia spp. e carrapatos
… entre carrapatos e espécies de Rickettsia endo simbiônticas é mediada por interações e mecanismos moleculares, ocorrendo através de genes e proteínas potencialmente codificadas nos genomas de ambos os organismos. Tratando-se de uma relação em nível molecular, buscamos predizer as …

High resolution modeling of tick density and detection of Rickettsia spp. in Dermacentor spp. ticks at Turnbull National Wildlife Refuge, WA
… of pathogens. One such pathogen is the bacteria Rickettsia rickettsii, which causes Rocky Mountain spotted fever. The detection of this bacterium in ticks at Turnbull National Wildlife Refuge (TNWR) indicates a potential risk to human health. In order to follow up on this discovery, we had two …

Identification of protective rickettsial antigens for vaccine development
The genus Rickettsia contains some of the most lethal pathogens known to man, including Rickettsia prowazekii, a select agent that could be used as a biological weapon. Although Rickettsia spp. cause important diseases of public health importance and there is a need to develop countermeasures for …

An observational study of ticks on the 30 Acre Lake Trail at Turnbull National Wildlife Refuge
… in past studies and the only known site of Rickettsia rickettsii pathogen isolated from ticks on the Turnbull National Wildlife Refuge (TNWR) to date. I hypothesize that there is a risk of infection of Rickettsia at this location, given the large tick density as well as the large density of …

The rickettsial effector Sca4 has a conserved interaction with host clathrin and a tick cell specific role in infection
… host proteins to carry out multiple functions. Rickettsia species are obligate intracellular bacteria that cause vector-borne diseases that constitute an ongoing public health threat. As Rickettsia spp. have small genomes, and thus a limited coding capacity, multifunctional effectors may be an …

Badgers (Meles meles) as reservoirs of vector-borne infections in the UK
… a battery of assays targeting the DNA of Babesia spp., Anaplasma phagocytophilum, Rickettsia, Borrelia and Trypanosoma spp. While badgers were found to be heavily infected with Babesia spp. (98.9% of blood samples from Gloucestershire and 100% from NE England), no A. phagocytophilum or Rickettsia …

Caracterización de especies de rickettsia en garrapatas (ixodidae) del municipio de Villeta, Cundinamarca y su relación con la epidemiología de la rickettsiosis en el mismo municipio
… dados los casos de mortalidad en humanos por Rickettsia rickettsii en el periodo 2003-2004, y las altas tasas de seropositividad frente al GFM tanto en habitantes de zona rural, como en animales domésticos. A pesar de esto, no se conoce la especie o especies de Rickettsia que circulan en las …
