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

Bactericidal Activity of Octenidine to Various Genospecies of Borrelia burgdorferi, Sensu Lato Spirochetes in Vitro and in Vivo [PDF]
Polish Journal of Microbiology, 2017 The aim of our studies was to invent a reliable method for detection of the bactericidal activity of disinfectants against Borrelia burgdorferi in suspension (in vitro) and in cell line cultures (in vivo). In the suspension method, 0.01% octenidine at 20&

Tick-Borne Rickettsioses in the Iberian Peninsula
Pathogens, 2022 Tick-borne rickettsioses (TBR) are caused by obligate, intracellular bacteria of the spotted-fever group (SFG) of the genus Rickettsia (Order Rickettsiales), transmitted by hard ticks.

‘Rickettsia hulinii’ belongs to the Rickettsia heilongjiangensis species [PDF]
Clinical Microbiology and Infection, 2009 A Rickettsia species has long been defined as a distinct serotype using mouse serotyping. However, owing to a lack of reproducibility and interlaboratory comparability of this method, new taxonomic guidelines, based on multigene amplification and sequencing, have been developed and validated by an international panel of rickettsiology experts [1]. This

THE CYTOLOGY OF RICKETTSIAE [PDF]
Journal of Experimental Medicine, 1949 Internal structures of rickettsiae seen with phase contrast microscopy and in the electron microscope contain desoxyribonucleic acid and are therefore nuclear structures similar to those found in bacteria. They are minute spherical bodies, either single as in spherical rickettsiae or varying in number from 2 to 4 in rod-shaped forms.

Inactivation of rickettsiae [PDF]
European Journal of Microbiology and Immunology, 2013 A reliable and complete inactivation is an indispensable premise for any concentration of rickettsiae or for the development of diagnostic strategies based on their antigens. This study deals with the testing of methods to inactivate rickettsiae. Rickettsia honei was used as a model organism.
