Introduction: Kurdistan Province in Iran is a historical focus for plague and tularemia. This study aimed at assessing the current status of these two foci by studying their rodent reservoirs.
Materials And Methods: Rodents were trapped and their ectoparasites were collected. The genus and species of both rodents and ectoparasites were determined. Serological analyses of rodent blood samples were done by enzyme-linked immunosorbent assay for plague and by standard tube agglutination assay for tularemia. Rodent spleen samples were subjected to bacterial culture, microscopic examination, and real-time PCR to search for active plague or tularemia infection.
Results: During this study, 245 rodents were trapped, of which the most abundant genera were Apodemus (40%), Mus (24.49%), and Meriones (12.65%). One hundred fifty-three fleas, 37 mites, and 54 ticks were collected on these rodents. The results of all direct and indirect tests were negative for plague. Serological tests were positive for tularemia in 4.8% of trapped rodents.
Discussion: This study is the first report on the presence of tularemia infection in rodents in Western Iran. Since Meriones persicus is a known reservoir for plague and tularemia, and this rodent carried plague and tularemia vectors in Marivan and Sanandaj districts, there is a real potential for the occurrence of these two diseases in this region.

Article Synopsis
- Infective endocarditis (IE) is a serious health issue, and this study investigates the presence of Coxiella burnetii and Bartonella spp. in heart valves in Iran.
- The research examined 146 patients who had heart valve surgery and found C. burnetii in 12 patients and Bartonella quintana in 15 patients, with two new C. burnetii genotypes identified.
- The study suggests that more research is needed to improve prevention, diagnosis, and treatment methods for Q fever endocarditis and Bartonella endocarditis.

Article Synopsis
- The study focuses on Crimean-Congo Hemorrhagic Fever (CCHF), which is a tick-borne viral disease, and aims to examine the presence of specific bacterial infections among individuals who are suspected of having CCHF in Iran.
- Researchers analyzed 260 serum samples from patients who tested negative for CCHF virus, finding 3.46% positive for brucellosis and 3.07% for Q fever, while no borreliosis or ehrlichiosis cases were detected.
- The findings suggest that bacterial infections like brucellosis and Q fever should be considered when diagnosing CCHF, and further broad investigations into bacterial infections with similar symptoms are recommended.

Article Synopsis
- Acute focal lymphadenitis in humans can occasionally be caused by zoonotic pathogens, which are transmitted without direct contact with infected animals, often via vectors.
- The text highlights various zoonotic diseases associated with lymphadenitis, including tularemia, plague, and rickettsioses, and summarizes their clinical signs, diagnosis, and treatment options.
- It recommends a combined antibiotic therapy for severe cases and emphasizes the need for a "one health approach" to enhance clinical outcomes and the understanding of these rare conditions.

Article Synopsis
- Wild rodents serve as reservoirs and hosts for various zoonotic helminths, impacting their survival and population dynamics due to parasitic diseases.
- A study in East Azerbaijan, Iran, collected 204 rodents from 17 species, finding a 67.16% prevalence of helminth infections, with particular species showing high infection and diversity rates.
- The research highlights health risks associated with zoonotic helminths in wild rodents and recommends further investigation into their prevalence in humans and potential transmission risks.
