Background: Ticks are a major arthropod vector of zoonotic diseases affecting both humans and domestic animals worldwide. Thus, studying tick microbiota would aid in understanding the potential threats posed by ticks. Methods: Approximately 8,000 unfed ticks, identified as Dermacentor nuttalli , were collected from sylvosteppe western Tianshan mountains. To investigate their pathogens, we divid...

In the present study, pathogenicity of four native strains of Entomopathogenic fungus; Metarhizium anisopliae, was studied against adult stage of Ixodes ricinus. For this purpose a total number of 180 adult ticks were examined in triplicate. Thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. Samples were incubated in separate Pet...

Introduction: Crimean-Congo Hemorrhagic Fever (CCHF) is a zoonotic viral infection transmitted mainly via CCHF virus-infected ticks between vertebrate hosts. The disease occurs in almost all provinces of Iran. This study investigated the CCHFV infection in hard ticks collected from livestock in the Sistan region of Sistan and Baluchestan Province, southeast of Iran. Methods: In this study, tick...

The economic importance of tick infestation on camels are important as they are important meat and milk producer animals in the less vegetation area of Iran and their health and production are greatly affected by the high tick infestation. In this investigation, tick infestations on camels (Camelus dromedarius) were determined in Qeshm Island, Iran. A total number of 912 adult ticks (472 males...

Ticks transmit mere different kinds ef pathogenic organisms than any other hematophagous arthropod. This paper attcmpts to review the literature available on the cell-mediated and humoTa] responses ofticks. The eell-mediated defense responses by invertebrates are impler than vertebrates, but are elTectivc as a second line ofdefense against invasion by microorganisms. Hemocytes play a major role...

background: west azerbaijan is considered as a main region for domestic animal breeding. due to importance of herd as a main host and ticks as a vector of relapsing fever and cchf, a comprehensive study was undertaken in the region. methods: outdoor, indoor collection as well as ticks stick to the animals' body were collected and identified. the study was conducted during the whole seasons in 2...

A study was conducted in Santa Cruz County to estimate the prevalence and distribution of the agents of Lyme disease, human granulocytic (HGE), and human monocytic (HME) ehrlichiosis in 1,187 adult ixodid ticks collected from eight public-use recreation areas over a 2-yr period. Borrelia burgdorferi, the causative agent of Lyme disease, was detected by a polymerase chain reaction (PCR) in 44 of...

BACKGROUND Ticks are the main vectors for transmission of different pathogens to human and animals. This survey was performed to find out distribution of ticks, which infested the domestic ruminants in Yazd Province, central Iran during year 2008-2009. METHODS A total number of 30 villages from both mountainous (20%) and plateau (80%) regions of the province were selected randomly. Ticks were...

The prevalence of the tick-borne spotted fever group rickettsioses pathogens in ticks collected Barnaul, administrative center Altai Krai, Western Siberia, was studied. causative agent lymphadenopathy (TIBOLA) Rickettsia raoultii revealed to be present 61.9% samples from Dermacentor ticks. Moreover, helvetica has been identified 5.1% Ixodes
