tick-borne diseases like tick-borne relapsing fever are a public health problem in iran. its occurrence is more prevalent in north part of country. in order to determine the distribution of soft ticks, argasidae, and their infection with borrelia species in hamadan province, 53 villages were selected randomly. a total of 4805 ticks were collected directly from human dwellings, poultries, and an...

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...

background: a molecular survey was conducted to investigatethe presence of pathogenic borrelia persica species caus­ing the tick borne relapsing fever (tbrf) in takistan district qazvin province, western iran. methods: a number of 1021 s oft ticks were collected from 31 villages including previously reported infected and none-infected tbrf cases and individually examined for the presenceof b. p...

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...

Introduction: Spirochetes of Borrelia can be visualized directly in infected ticks by dark-field microscopy. Inoculation of in phosphate buffered saline (PBS) suspension of ground Argasid soft ticks to susceptible animals or allowing the ticks to feed on the same species followed by microscopic examination of the animals’ blood have also been practiced. With the advent of molecular method...

The book Australian Ticks by F.H.S. Roberts (1970) is a land-mark in Australian tick biology. But it is time for a new and improved book on the ticks of Australia. The present book has identification guides and accounts of the biology and diseases associated with the 16 species of ticks that may feed on domestic animals and humans in Australia. These comprise five argasid (soft) ticks: Argas pe...
