Wolbachia in the Culex pipiens group mosquitoes: introgression and superinfection. [PDF]

open access: yes, 2009
Wolbachia bacteria in mosquitoes induce cytoplasmic incompatibility (CI), where sperm from Wolbachia-infected males can produce inviable progeny. The wPip strain in the Culex pipiens group of mosquitoes produces a complexity of CI crossing types. Several

Effect ofRickettsia rickettsii(Rickettsiales: Rickettsiaceae) Infection on the Biological Parameters and Survival of Its Tick Vector—Dermacentor variabilis(Acari: Ixodidae) [PDF]

open access: yesJournal of Medical Entomology, 2015
Rocky Mountain spotted fever, caused by Rickettsia rickettsii, is a potentially fatal tick-borne disease spread from North America to Argentina. The major vectors of R. rickettsii in the United States are Dermacentor andersoni Stiles and Dermacentor variabilis (Say). It is generally believed that vector ticks serve as major reservoirs of R.

Factors influencing in vitro infectivity and growth of Rickettsia peacockii (Rickettsiales: Rickettsiaceae), an endosymbiont of the Rocky Mountain wood tick, Dermacentor andersoni (Acari, Ixodidae) [PDF]

open access: yesJournal of Invertebrate Pathology, 2005
Rickettsia peacockii, a spotted fever group rickettsia, is a transovarially transmitted endosymbiont of Rocky Mountain wood ticks, Dermacentor andersoni. This rickettsia, formerly known as the East Side Agent and restricted to female ticks, was detected in a chronically infected embryonic cell line, DAE100, from D. andersoni.

Using bacteria to treat diseases.

open access: yes, 2012
INTRODUCTION: Mosquito-borne diseases such as malaria and dengue fever result in significant morbidity and mortality in developing countries. Vector control is often the most effective strategy to prevent disease transmission and novel methods are ...

First investigation of pathogenic bacteria, protozoa and viruses in rodents and shrews in context of forest-savannah-urban areas interface in the city of Franceville (Gabon) [PDF]

open access: yes, 2021
Rodents are reservoirs of numerous zoonotic diseases caused by bacteria, protozoans, or viruses. In Gabon, the circulation and maintenance of rodent-borne zoonotic infectious agents are poorly studied and are often limited to one type of pathogen.

Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

open access: yesPublic Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Infection Rates and Characterisation of Rickettsia africae (Rickettsiaceae) Detected in Amblyomma Species from Southern Africa

open access: yesMicroorganisms
Tick-borne rickettsioses are considered among the oldest known vector-borne zoonotic diseases. Among the rickettsiae, Rickettsia africae is the most reported and important in Africa, as it is the aetiological agent of African tick bite fever (ATBF). Studies describing the prevalence of R.

A comparison of super‐resolution microscopy techniques for imaging tightly packed microcolonies of an obligate intracellular bacterium

open access: yesJournal of Microscopy, Volume 301, Issue 2, Page 187-205, February 2026.
Abstract Conventional optical microscopy imaging of obligate intracellular bacteria is hampered by the small size of bacterial cells, tight clustering exhibited by some bacterial species and challenges relating to labelling such as background from host cells, a lack of validated reagents, and a lack of tools for genetic manipulation.
