Spotted Fever Group Rickettsiae: A Brief Review and a Canadian Perspective [PDF]

Zoonoses and Public Health, 2012
SummarySpotted fever group rickettsioses (SFGR) are infections caused by established and emerging human pathogens worldwide. These rickettsial agents are transmitted to humans via arthropods and may result in mild to severe and potentially fatal diseases. Spotted fever group rickettsioses are characterized by similar clinical features, including fever,

Molecular Screening of Black Flies (Diptera: Simuliidae) for Vector‐Borne Zoonotic Pathogens, South Moravia, Czech Republic

Zoonoses and Public Health, Volume 73, Issue 1, Page 95-106, February 2026.
ABSTRACT Introduction Black flies (Simuliidae) are globally distributed blood‐feeding arthropods and vectors of viral, bacterial, and parasitic pathogens to many animal species, including humans. We investigated the occurrence of selected vector‐borne pathogens in black flies in South Moravia, Czech Republic, and evaluated their possible role in the ...

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

Advanced Science, Volume 13, Issue 5, 27 January 2026.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Genetic Diversity of Theileria parva and Anaplasma spp. Isolated From Ticks Collected From Kiambu County, Kenya

BioMed Research International, Volume 2026, Issue 1, 2026.
Environmental changes and human activities such as deforestation and expansion of agricultural land are increasing tick‐borne diseases including Anaplasmosis, Babesiosis, Ehrlichiosis, and Theileriosis. These diseases, which affect animals, can be transmitted to humans through tick bites.
