Diversity, Host Attachment Preferences and Role of Tick Rhipicephalus microplus in the Transmission of Bartonella spp. and Rickettsia spp. in Cattle From Southern Benin

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Ticks infesting cattle in Southern Benin were investigated for diversity, attachment preferences and zoonotic bacteria. Among 2210 ticks collected from 540 cattle, Rhipicephalus microplus predominated (79.6%). Ticks mainly attached to ears, axillae and trunk. PCR detection revealed Bartonella spp. and Rickettsia spp., highlighting veterinary and public

Q Fever, Scrub Typhus, and Rickettsial Diseases in Children, Kenya, 2011–2012

Emerging Infectious Diseases, 2016
To increase knowledge of undifferentiated fevers in Kenya, we tested paired serum samples from febrile children in western Kenya for antibodies against pathogens increasingly recognized to cause febrile illness in Africa. Of patients assessed, 8.9%, 22.4%

Functional Stability of Tetracycline: Practical Information for Its Use in Bacterial Selection

APMIS, Volume 134, Issue 5, May 2026.
ABSTRACT Genetic manipulation is widely employed in laboratories for purposes such as gene function characterization, the development of novel traits in transformed microorganisms, and the production of biotechnologically relevant compounds. A key step in this process is the selection of mutant strains, often facilitated by antibiotics.

Detection of Rickettsiae, Borreliae, and Ehrlichiae in Ticks Collected from Walker County, Texas, 2017–2018

Insects, 2019
Cases of tick-borne diseases, including spotted fever rickettsioses, borreliosis, babesiosis, anaplasmosis and ehrlichiosis, in the United States and territories have more than doubled from 2004 to 2016 and account for 77% of all vector-borne disease ...

Estudo da infecção por Rickettsias do grupo da febre maculosa em humanos e carrapatos de um parque urbano na Cidade de Londrina, Estado do Paraná [PDF]

, 2011
INTRODUCTION: Spotted fevers are emerging zoonoses caused by Rickettsia species in the spotted fever group (SFG). Rickettsia rickettsii is the main etiologic agent of Brazilian spotted fever (BSF) and it is transmitted by Amblyomma spp. ticks.

Molecular Phylogeny and Strain Genotyping of the Bacterial Endosymbiont Wolbachia Associated With Tuta absoluta Populations

Entomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 387-397, May 2026.
This study was designed to understand the association between reproductive endosymbiotic bacteria and wild and laboratory‐reared Tuta absoluta populations. The majority of T. absoluta populations showed Wolbachia presence at varying levels of infection, whereas Arsenophonus, Cardinium, and Spiroplasma were not detected. Wolbachia‐positive T.

Spotted Fever Rickettsiosis in a Wildlife Researcher in Sabah, Malaysia: A Case Study

Tropical Medicine and Infectious Disease, 2018
We present evidence for a case of spotted fever rickettsiosis with severe complications in a young adult male. Although spotted fever group rickettsiae (SFGR) have been reported as the most prevalent cause of rickettsiosis in rural areas of Sabah ...

Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk

Journal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT Piscirickettsia salmonis, the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.

Elevated Temperatures Disrupt Wolbachia‐Induced Feminisation and Reshape Microbial Community Dynamics Across Generations in a Spider Host

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Longitudinal microbial interactions within a host are challenging to study, leading to a focus on constructed microbial communities in vitro settings. Here, we take advantage of a naturally defined microbial community within a spider host to study how elevated temperatures influence microbial dynamics and phenotypes across host generations ...
