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.

Rickettsia lusitaniae in Ornithodoros Porcinus Ticks, Zambia
Pathogens, 2021 Rickettsial pathogens are amongst the emerging and re-emerging vector-borne zoonoses of public health importance. Though traditionally considered to be transmitted by ixodid ticks, the role of argasid ticks as vectors of these pathogens is increasingly ...

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.

Molecular detection of Rickettsia in fleas from micromammals in Chile
Parasites & Vectors, 2020 Background Rickettsial diseases are considered important in public health due to their dispersal capacity determined by the particular characteristics of their reservoirs and/or vectors.

Dissemination of spotted fever rickettsia agents in Europe by migrating birds. [PDF]
PLoS ONE, 2010 Migratory birds are known to play a role as long-distance vectors for many microorganisms. To investigate whether this is true of rickettsial agents as well, we characterized tick infestation and gathered ticks from 13,260 migratory passerine birds in ...

A Case Series on Neurological Insights of Scrub Typhus [PDF]
Journal of Clinical and Diagnostic Research, 2020 Scrub typhus is a rickettsial disease caused by gram negative coccobacilli and transmitted through the bite of larval stage of mite. The disease is notable in the Asia-Pacific belt with few sporadic and epidemic cases reported from India as well.

Ticks and Tick-borne Diseases, 2017 Tick-borne diseases represent a large proportion of infectious diseases that have become a world health concern. The presence of Rickettsia spp. was evaluated by standard PCR and sequencing in 123 ticks collected from several mammals and vegetation in Sardinia, Italy.
