Tropism and pathogenicity of rickettsiae [PDF]

open access: yesFrontiers in Microbiology, 2012
Rickettsiae are obligate intracellular parasitic bacteria that cause febrile exanthematous illnesses such as Rocky Mountain spotted fever, Mediterranean spotted fever, epidemic and murine typhus, etc. Although the vector ranges of each Rickettsia species

Eco-Epidemiological Study of Seropositivity Against Rickettsia and Leptospira Agents in Rural Areas of Urabá, Colombia. [PDF]

open access: yesTrop Med Int Health
ABSTRACT Introduction Rickettsioses and leptospirosis are infectious diseases often underdiagnosed due to limited knowledge about their epidemiology, pathophysiology, and clinical aspects. Objectives To characterize the seroprevalence and seroincidence of Rickettsia and Leptospira agents and determine their associated factors in rural areas of Urabá ...

Spotted fever group rickettsiae associated with ixodid ticks in wild environment in Southern Italy

open access: yesMicrobiologyOpen, 2018
Ixodidae ticks are vectors and reservoirs of several species of rickettsiae, and tick‐borne rickettsioses are reported worldwide. This study was aimed to verify the distribution of spotted fever group rickettsiae associated with ticks in a wild ...

Vaccine Design and Vaccination Strategies against Rickettsiae

open access: yesVaccines, 2021
Rickettsioses are febrile, potentially lethal infectious diseases that are a serious health threat, especially in poor income countries. The causative agents are small obligate intracellular bacteria, rickettsiae.

Surveillance of vector-borne infections: Dogs as sentinel animals for Orientia and Rickettsia exposure in five regions in Chile [PDF]

open access: yesOne Health
Domestic dogs have been proposed as sentinels for various infectious diseases, including rickettsial infections. In Chile, the only endemic human rickettsiosis is scrub typhus caused by Candidatus Orientia chiloensis, an emerging infectious disease ...

Plasmids and rickettsial evolution: insight from Rickettsia felis. [PDF]

open access: yesPLoS ONE, 2007
The genome sequence of Rickettsia felis revealed a number of rickettsial genetic anomalies that likely contribute not only to a large genome size relative to other rickettsiae, but also to phenotypic oddities that have confounded the categorization of R.

Black holes”, “Genome fluidity”, and Evolution of Bacterial Species [PDF]

open access: yesReviews in Clinical Medicine, 2022
The formation of the massive deletion of genes called “black holes,” which are detrimental to a pathogenic lifestyle, provides a bacterial evolutionary route that permits a pathogen to augment virulence and host-adaptability.
