Rickettsia spp. in Ticks of South Luangwa Valley, Eastern Province, Zambia

Microorganisms, 2023
Ticks are important vectors for Rickettsia spp. belonging to the Spotted Fever Group responsible for causing Rickettsiosis worldwide. Rickettsioses pose an underestimated health risk to tourists and local inhabitants. There is evidence of the presence of

Acute febrile illness is associated with Rickettsia spp infection in dogs [PDF]

, 2015
BACKGROUND: Rickettsia conorii is transmitted by Rhipicephalus sanguineus ticks and causes Mediterranean Spotted Fever (MSF) in humans. Although dogs are considered the natural host of the vector, the clinical and epidemiological significance of R ...

Evolutionary Convergence of Nutritional Symbionts in Ticks

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Confocal imaging of nutritional symbionts in the ovaries of ticks using fluorescence in situ hybridisation. ABSTRACT Symbiosis with bacteria is essential for the survival of animals with an obligate blood‐feeding lifestyle. In ticks, two distinct bacterial lineages, Coxiella‐like and Francisella‐like endosymbionts, have independently evolved into ...

Composition and Seasonal Variation of Rhipicephalus turanicus and Rhipicephalus sanguineus Bacterial Communities [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT A 16S rRNA gene approach, including 454 pyrosequencing and quantitative PCR (qPCR), was used to describe the bacterial community in Rhipicephalus turanicus and to evaluate the dynamics of key bacterial tenants of adult ticks during the active questing season. The bacterial community structure of

A combination of antibodies against Bm86 and Subolesin inhibits engorgement of Rhipicephalus australis (formerly Rhipicephalus microplus) larvae in vitro

Parasites & Vectors, 2019
Rhipicephalus microplus is a hard tick species that has a high impact on cattle health and production in tropical and subtropical regions. Recently, ribosomal DNA and morphological analysis resulted in the reinstatement of R.

Mitochondrial heteroplasmy in an avian hybrid form (Passer italiae: Aves, Passeriformes) [PDF]

, 2019
Mitochondrial heteroplasmy is the result from biparental transmission of mitochondrial DNA (mtDNA) to the offspring. In such rare cases, maternal and paternal mtDNA is present in the same individual.

Sufficient reproduction numbers to prevent recurrent epidemics

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1186-1200, June 2025.
Abstract Current practice in the design and evaluation of control measures in disease ecology and epidemiology, including vaccination, is largely based on reproduction numbers (RNs), which represent prognostic indices of long‐term disease transmission, both in naïve populations (basic RN) and in the presence of prior exposure or infection containment ...
