Rickettsia rickettsii in Amblyomma patinoi ticks, Colombia. [PDF]

Emerg Infect Dis, 2015
Para el editor: Rickettsia rickettsii es el agente etiológico de la fiebre maculosa de las Montañas Rocosas (RMSF), una rickettsiosis transmitida por garrapatas altamente letal restringida al hemisferio occidental (1,2). En Colombia, R. rickettsii se informó por primera vez durante la década de 1930, cuando 62 (95%) de 65 personas afectadas murieron de

Phenology and habitat associations of the invasive Asian longhorned tick from Ohio, USA

Medical and Veterinary Entomology, Volume 38, Issue 3, Page 314-324, September 2024.
Asian longhorned tick (ALT) nymphs emerged in June, followed by adults, and concluded with larvae in fall. Potential differences in phenology were identified between Ohio and Eastern Coast US states. ALTs were detected in all habitat types including grassland, forest and edge, but not on wildlife hosts, including small‐ and medium‐sized mammals and ...

Cascading effects of mammal host community composition on tick vector occurrence at the urban human–wildlife interface

Ecosphere, Volume 15, Issue 8, August 2024.
Abstract Habitat fragmentation and host community composition are implicated as key drivers of changing tick populations and tick‐borne pathogen dynamics, altering infection risk through coupled socioecological pathways that mediate interactions between tick vectors, vertebrate hosts, and humans.

Reassessment of the genetic basis of natural rifampin resistance in the genus Rickettsia

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
Contrary to previous studies, the natural resistance of Rickettsia, a genus of intracellular bacteria, to the antibiotic rifampin is not solely due to the Leu‐973 residue in the RNA polymerase β subunit. Abstract Rickettsia, a genus of obligate intracellular bacteria, includes species that cause significant human diseases.

Dying for a cause: The pathogenic manipulation of cell death and efferocytic pathways

Molecular Oral Microbiology, Volume 39, Issue 4, Page 165-179, August 2024.
Abstract Cell death is a natural consequence of infection. However, although the induction of cell death was solely thought to benefit the pathogen, compelling data now show that the activation of cell death pathways serves as a nuanced antimicrobial strategy that couples pathogen elimination with the generation of inflammatory cytokines and the ...

Antibodies against rickettsiae from spotted fever groups in horses from two mesoregions in the state of Santa Catarina, Brazil

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
Bacteria of the Rickettsia genus are agents of Brazilian Spotted Fever (BSF), a zoonotic disease which is difficult to diagnose, evolves quickly and can result in death. Antibodies against Rickettsia spp.

The Ticks (Arachnida: Acari: Ixodida) of Arkansas [PDF]

, 2016
Although ticks are a nuisance to humans and other animals, they are an important part of the biota of North America. In addition, they are vectors of many tick-borne disease agents that can negatively affect higher vertebrates.
