Spotted Fever Group Rickettsia sp. Closely Related to Rickettsia japonica, Thailand [PDF]

Emerging Infectious Diseases, 2009
To the Editor: In response to a recent report that suggested human infection with Rickettsia japonica in northeastern Thailand (1), we phylogenetically reexamined spotted fever group rickettsiae (SFGR) from Thailand. The organism had been isolated from a male Haemaphysalis hystricis tick found on Mt.

Eco‐Epidemiological Study of Seropositivity Against Rickettsia and Leptospira Agents in Rural Areas of Urabá, Colombia

Tropical Medicine &International Health, Volume 31, Issue 11, Page 1569-1583, November 2026.
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 in Ticks from Missouri

Ticks and Tick-borne Diseases, 2018
Tick-borne rickettsioses pose a major health threat among vector-borne infections in Missouri but there are some uncertainties regarding the vector competence and range of tick species, as well as the virulence of certain bacterial species. A survey was developed and implemented to assess local healthcare practitioners' awareness of the prevalence and ...

Reactivity of monoclonal antibodies to Rickettsia rickettsii with spotted fever and typhus group rickettsiae [PDF]

Journal of Clinical Microbiology, 1987
Analysis of 15 spotted fever group (SFG) and 2 typhus group strains of rickettsiae with a panel of monoclonal antibodies revealed a number of shared and unique epitopes of the 120- and 155-kilodalton surface proteins. All of the SFG strains but neither of the typhus group strains reacted with antibody to the lipopolysaccharidelike antigen of Rickettsia
