First molecular diagnosis of the human pathogen Rickettsia raoultii and other spotted fever group rickettsiae in Sudanese ixodid ticks from domestic ruminants

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
In this manuscript, the authors collected ixodid ticks and examined the presence of Rickettsia species by PCR. By performing sequencing and phylogenetic analysis, the authors identified the presence of four different Rickettsia species in three tick species found on three mammalian hosts.

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.

Rapid, simple, and sensitive detection of the ompB gene of spotted fever group rickettsiae by loop-mediated isothermal amplification [PDF]

, 2012
BACKGROUND: Spotted fever caused spotted fever group rickettsiae (SFGR) is prevalent throughout China. In this study, we describe a rapid, simple, and sensitive loop-mediated isothermal amplification (LAMP) assay targeting the ompB gene of spotted fever ...

Amblyomma imitatorTicks as Vectors ofRickettsia rickettsii, Mexico

Emerging Infectious Diseases, 2010
Real-time PCR of Amblyomma imitator tick egg masses obtained in Nuevo Leon State, Mexico, identified a Rickettsia species. Sequence analyses of 17-kD common antigen and outer membrane protein A and B gene fragments showed to it to be R. rickettsii, which suggested a potential new vector for this bacterium.

Detection of Borrelia lusitaniae, Rickettsia sp. IRS3, Rickettsia monacensis and Anaplasma phagocytophilum in Ixodes ricinus collected in Madeira Island, Portugal [PDF]

, 2008
A total of 300 Ixodes ricinus ticks were tested by polymerase chain reaction (PCR) for the presence of Borrelia spp., Rickettsia spp., and Anaplasma phagocytophilum. Sequence analysis demonstrated 8 (2.7%) ticks infected with B. lusitaniae, 60 (20%) with

Antibodies for Rickettsia spp. in patients with negative serology for dengue virus, leptospirosis, and meningococcal disease in municipalities of São Paulo State, Brazil

Revista da Sociedade Brasileira de Medicina Tropical
INTRODUCTION Brazilian spotted fever is an infectious disease with a high mortality rate if not treated early. Differential diagnosis is difficult, as the first clinical signs are non-specific and can be confused with other diseases.

Antibody titers reactive with Rickettsia rickettsii in blood donors and implications for surveillance of spotted fever rickettsiosis in the United States.

Journal of Infectious Diseases, 2019
BACKGROUND Since 2000, the reported prevalence of tick-borne spotted fever group rickettsioses (SFGR) has increased considerably. We compared the level of antibody reactivity among healthy blood donors from two widely separated regions of the United ...
