چکیده

زمینه مطالعه: آلودگی سگ به بندپایان انگل خارجی دارای اهمیت بهداشت انسانی و دامپزشکی در دنیا و ایران به دلیل انتقال عوامل بیماریزا می‌باشد. هدف: هدف از این مطالعه تعیین فراوانی و تنوع گونه‌ای بندپایان انگل خارجی در سگ‌های منطقه گیلانغرب بود. روش کار: 138 قلاده سگ (93 قلاده سگ گله و 45 قلاده سگ نگهبان) به روش تصادفی ساده از فروردین ماه سال1391 تا خرداد ماه سال 1392 مطالعه گردیدند. سطح بدن سگ‌ها از نظر آلودگی به کنه‌های سخت بررسی گردیده و در امتداد ضمایم دهانی جدا شدند. جرب‌ها مستقیماً از پوست و یا با تخریش و هضم آن جمع‌آوری گردیدند. کک و شپش نیز از سطح بدن جدا گردید و شناسایی شدند. نتایج: آلودگی به انگل‌های خارجی در 65 قلاده سگ گله (11/47%) و 43 قلاده سگ نگهبان (16/31%) بود. فراوانی آلودگی در سگ‌های نر نسبت به سگ‌های ماده کمتر از یک سال اختلاف معنی‌داری داشت (05/0≥p). بیشترین و کمترین آلودگی کنه سخت به ترتیب از گونه‌های ریپی سفالوس سانگوینوس (36/35%) و هیالوما مارجیناتوم مارجیناتوم (06/3%) بود. نسبت تعداد کنه به هر قلاده سگ 13/2 با بیشترین توزیع بدنی کنه ریپی سفالوس سانگوینوس (82/24%) در سطح داخلی لاله گوش بود (05/0≥p). اختلاف فراوانی آلودگی کنه سخت در فصل بهار (82/33%) نسبت به سایر فصول معنی‌دار بود (05/0≥p). 35 قلاده سگ (14/25%) از سگ‌های تحت مطالعه آلوده به سارکوپتس اسکابیئی (33/15%)، دمودکس کنیس (81/9%)، کتنوسفالیدس کنیس (52/6%)، پولکس ایریتانس (62/3%) و تریکودکتس کنیس (35/4%) بودند. نتیجه گیری نهایی: نتایج این تحقیق نشانگر وجود تنوع گونه‌ای در فون انگل‌های خارجی سگ‌های منطقه بود که می‌توانند در انتقال آن‌ها به انسان و نیز انتقال عوامل عفونت زا به سگ ایفای نقش کنند.

چکیده [English]

BACKGROUND: Canine infestation of ectoparasites is of medical and veterinary importance worldwide and in Iran due to transmission of pathogen agents. OBJECTIVES: The present study was aimed to determine prevalence and species diversity of ectoparasites in dogs of Gilanegharb suburb of Kermanshah province, Iran. METHODS: A total of 138 dogs (93 sheepdogs and 45 watchdogs) were randomly selected and examined from March 2012 to May 2013. The body surface was investigated for ixodid ticks and removed along with the mouthparts. The mites were also removed directly from the skin and/or using skin scraping and then digested. Fleas and lice were collected from body surface of examined dogs and identified. RESULTS: The results indicated that 65 sheepdogs (47.11%) and 43 watchdogs (31.16%) were infested with ectoparasites. There was a significant difference between prevalence and sex in dogs aged less than one-year-old (p≤0.05). The maximum and minimum ixodid ticks infestations were respectively for Rhipicephalus sanguineus (35.36%) and H. marginatum marginatum (3.06%). Tick indices (number of tick per each animal) were 2.13 with the highest body distribution in ear (24.82%) of R. sanguineus (p≤0.05). The frequency of ixodid tick infestation was significantly higher in spring (33.82%) than other seasons. Thirty five dogs (25.14%) out of all examined dogs were infested with Sarcoptes scabiei (15.33%), Demodex canis (9.81%), Ctenocephaloides canis (6.52%), Pulex irritans (3.62%), and Trichodectes canis (4.35%). CONCLUSIONS: From the results of the current study, it was concluded that there was species diversity in dogs’ ectoparasites fauna which can be transmitted to humans and served as the carrier for spreading the infective agents in the region.
