AI Article Synopsis
- CCHFV is a dangerous virus with a 30% fatality rate transmitted through tick bites and contact with infected livestock, occurring sporadically in various regions.
- A molecular survey conducted in Golestan Province, Iran, found CCHFV in 5.3% of hard ticks collected, mainly from species like Hyalomma and Rhipicephalus.
- The findings indicate that Hyalomma ticks are the primary vectors for CCHFV in the area, prompting recommendations for preventive measures like acaricides and repellents to reduce tick exposure.
Article Abstract
Background & Objectives: Crimean-Congo haemorrhagic fever virus (CCHFV) causes severe disease with fatality rate of 30%. The virus is transmitted to humans through the bite of an infected tick, direct contact with the products of infected livestock as well as nosocomially. The disease occurs sporadically throughout many of African, Asian and European countries. Different species of ticks serve either as vector or reservoir for CCHFV. This study was aimed to determine the prevalence of CCHFV in hard ticks (Ixodidae) in the Golestan Province of Iran.
Methods: A molecular survey was conducted on hard ticks (Ixodidae) isolated from six counties in Golestan Province, north of Iran during 2014-15. The ticks were identified using morphological characteristics and presence of CCHFV RNA was detected using RT-PCR.
Results: Data revealed the presence of CCHFV in 5.3% of the ticks selected for screening. The infected ticks belonged to Hyalomma dromedarii, Hy. anatolicum, Hy. marginatum and Rhipicephalus sanguineus species.
Interpretation & Conclusion: The study demonstrated that Hyalomma ticks are the main vectors of CCHFV in Golestan Province. Thus, preventive strategies such as using acaricides and repellents in order to avoid contact with Hyalomma ticks are proposed.

Introduction: Multidrug-resistant (MDR) bacteria like Proteus species have led to more prolonged hospitalizations, fewer care choices, higher treatment costs, and even death. The present study aims to evaluate the prevalence of MDR Proteus species in clinical samples and to suggest the best therapeutic options for the MDR Proteus species.
Methodology: Clinical samples were collected randomly from five hospitals in Golestan Province, Iran, from February 2017 to July 2019.
