Rickettsia felis DNA recovered from a child who lived in southern Africa 2000 years ago

Communications Biology, 2023
Ancient genomic evidence for Rickettsia felis presence in human remains from 2000 years ago reframes previous hypotheses of R. felis as a novel or emergent pathogen in modern humans.

Ecology of Rickettsia felis: a review.

Journal of medical entomology, 2009
It has been two decades since the first description of Rickettsia felis, and although a nearly cosmopolitan distribution is now apparent, much of the ecology of this unique microorganism remains unresolved. The cat flea, Ctenocephalides felis, is currently the only known biological vector of R. felis; however, molecular evidence of R.

The role of cofeeding arthropods in the transmission of Rickettsia felis

PLOS Neglected Tropical Diseases, 2022
Rickettsia felis is an emerging etiological agent of rickettsioses worldwide. The cosmopolitan cat flea (Ctenocephalides felis) is the primary vector of R. felis, but R. felis has also been reported in other species of hematophagous arthropods including ticks and mosquitoes.

First detection of Rickettsia felis in Ctenocephalides felis fleas from Italy [PDF]

Clinical Microbiology and Infection, 2009
Members of the genus Rickettsia are commonly associated with haematophagous arthropods such as ticks, fleas or lice. Rickettsia felis is a bacterium belonging to the spotted fever group of the genus Rickettsia. It was first detected by Adams et al. in 1990 [1] in the midgut cells of a cat flea (Ctenocephalides felis), and was later described as a new ...

Seasonal and Gender Differences in Presence of Rickettsia felis and Blood meals Provide Additional Evidence of a Vector Role for Mosquitoes

Canadian Journal of Infectious Diseases and Medical Microbiology, 2019
Rickettsia felis belongs to spotted fever group Rickettsia and is an emerging human pathogen most commonly transmitted by a range of fleas and ticks. While recent evidence has suggested mosquitoes are infected with R.

The molecular identity of fleas (Siphonaptera) carrying Rickettsia felis, Bartonella clarridgeiae and Bartonella rochalimae from dogs and cats in Northern Laos

Heliyon, 2020
Cat fleas (Ctenocephalides felis) are the most commonly recognised ectoparasites of domestic pets globally and are frequently implicated in the transmission of a variety of zoonotic vector-borne pathogens.

Culture Isolate of Rickettsia felis from a Tick

International Journal of Environmental Research and Public Health, 2022
Although the cat flea, Ctenocephalides felis, has been identified as the primary vector of Rickettsia felis, additional flea, tick, mite, and louse species have also been associated with this bacterium by molecular means; however, the role of these arthropods in the transmission of R. felis has not been clarified.

Rickettsia felis Infection in Febrile Children, Ghana [PDF]

The American Society of Tropical Medicine and Hygiene, 2017
Rickettsial infections are an underrecognized cause of febrile illness in sub-Saharan Africa. To evaluate the epidemiology and clinical features of rickettsial disease in pediatric patients in Ghana, we screened blood samples from febrile children aged less than 15 years presenting to an outpatient department in Ghana's Ashanti Region for the presence ...

A novel Rickettsia subspecies closely related to Rickettsia felis in Aedes albopictus from Qingdao City, Eastern China

Frontiers in Cellular and Infection Microbiology
Mosquitoes are generally regarded as the main vectors for many zoonotic diseases, capable of transmitting various diseases and causing significant public health burdens. In this study, a total of 232 Aedes albopictus mosquitoes were captured from Qingdao
