Investigation of Ehrlichia Species Infection in Dogs in Kerman Province, Iran, during ۲۰۱۲–۲۰۲۲

Background: Ehrlichiosis is an emerging zoonotic infection of growing importance in tropical and subtropical regions, affecting both veterinary and public health. In Iran, the only documented form is canine monocytic ehrlichiosis (CME), caused by Ehrlichia canis and transmitted via ticks infesting infected dogs. Understanding its epidemiology is essential for effective control and prevention. Methods: The present study systematically reviewed and analyzed research conducted between ۲۰۱۲ and ۲۰۲۲ in Kerman Province. The focus was on the role of ticks as vectors and the molecular identification of Ehrlichia species in dogs and their associated ticks. Results: The reviewed studies revealed variable prevalence rates of canine monocytic ehrlichiosis (CME) among dogs. Molecular analyses identified Ehrlichia canis as the dominant species. Ticks associated with infected dogs were confirmed as the principal vectors, and morphological examinations further characterized their genera and species. The polymerase chain reaction (PCR) was the main diagnostic technique applied, enabling accurate detection and differentiation of Ehrlichia species. Conclusion: Considering the diversity of CME prevalence reported in various studies across Kerman Province, indicating the presence of high-risk endemic foci, it is recommended to establish a regional continuous surveillance program for dogs and their ticks. Such a program should include periodic sampling, owner education regarding tick infestation, and the development of treatment protocols based on early diagnosis. Moreover, this review provides a comprehensive overview of prevalence patterns, dominant species, and diagnostic approaches, serving as a foundation for future surveillance, prevention, and control strategies.
