The identification of the Tick Borne Relapsing Fever (TBRF) agent in Israel and the Palestinian Authority relies on the morphology and the association of Borrelia persica with its vector Ornithodoros tholozani. Molecular based data on B. persica are very scarce as the organism is still non-cultivable. In this study, we were able to sequence three complete 16S rRNA genes, 12 partial flaB genes, ...
هدف: تب راجعه کنهای بیماری حاد عفونی است که توسط اسپیروکتی به نام بورلیا پرسیکا ایجاد و توسط کنه‌های نرم اورنیتودوروس تولوزانی منتقل میشود. این بیماری در خاورمیانه و نیز مناطق زیادی از کشور ایران دیده میشود. یکی از مشکلات موجود درباره این بیماری تعیین آلودگی در کنهها برای تعیین ناقل بیماری است که به روش کلاسیک گزنودیاگنوزیز انجام میشود که عبارت است از خوندهی کنهها روی حیوان حساس آزمایشگا...
چکیده زمینه و هدف: کنه ی اورنیتودوروس تولوزانی با گزش و خون خواری از انسان از اهمیت پزشکی و بهداشتی خاصی برخوردار است. به رغم اهمیت پزشکی و بهداشتی این کنه، تاکنون مطالعات دقیقی جهت تفکیک فرم های مختلف و استعداد های آن ها در انتقال بیماری انجام نیافته است. به همین دلیل برای تعیین تنوع فنوتیپی و آلودگی سویه های مختلف این کنه به بورلیا پرسیکا در استان زنجان، مطالعه ی حاضر انجام یافت. روش بررسی: د...
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...
Bakground and Objective: The soft tick, Ornithodoros tholozani, is of major medical importance due to biting humans and taking blood-meal. Despite the medical importance of this tick, no in-depth studies have been carried out to distinguish different forms and their capability in transmitting the disease. To this end, this study was carried out to identify phenotypic diversity, and contaminatio...
BACKGROUND A molecular survey was conducted to investigate the 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 soft ticks were collected from 31 villages including previously reported infected and none-infected TBRF cases and individually examined for the presence of B. p...
Tick-borne relapsing fever (TBRF) is an arthropod-borne infection found in the Middle East, Africa, Europe and North America. The disease is caused by several species of Borrelia and transmitted by various species of soft ticks [1,2]. Specific relationships usually exist between Borrelia species, the vector ticks and the distribution area [3]. Ornithodoros tholozani is distributed in the Middle...
In this paper, the authors report ticks parasitizing bats from the Serra das Almas Natural Reserve (RPPN) located in the municipality of Crateús, state of Ceará, in the semiarid Caatinga biome of northeastern Brazil. The study was carried out during nine nights in the dry season (July 2012) and 10 nights in the rainy season (February 2013). Only bats of the Phyllostomidae and Mormoopidae famili...
Selected species of mosquitoes and Ornithodoros ticks were evaluated for their potential to transmit Karshi and Langat (tick-borne encephalitis virus complex) viruses in the laboratory. Although there was no evidence of replication of Karshi virus in either of the two mosquito species tested [Ochlerotatus taeniorhynchus (Wiedemann) or Culex pipiens (L.)], Karshi virus replicated in and was tran...
BACKGROUND Relapsing fever is the most frequent bacterial disease in Africa. Four main vector / pathogen complexes are classically recognized, with the louse Pediculus humanus acting as vector for B. recurrentis and the soft ticks Ornithodoros sonrai, O. erraticus and O. moubata acting as vectors for Borrelia crocidurae, B. hispanica and B. duttonii, respectively. Our aim was to investigate the...
