چکیده مقاله :
در طی زمستان سال 1390 تا زمستان سال 1391 تعداد 50 عدد نمونه ماهی کفشک راست گرد(کفشک گرد) با نام علمیBrachirus orientalis(Bloch & Schneider, 1801)از اسکله های صیادی شهرستان بندری آبادان واقع در شمال خلیج فارس اخذ گردید. نمونه ها به آزمایشگاه آبزیان دانشگاه چمران اهواز منتقل شد ومطالعه بر روی ماهی مورد اشاره صورت گرفت این مطالعه به منظور اندازه گیری غلظت فلز سرب در بافت کبد ماهی مورد نظر و بررسی تأثیر طول کل و جنسیت ماهی بر میزان تجمع فلز سرب در کبد ماهی صورت گرفت. میزان غلظت فلز سرب در رسوبات منطقه نیز اندازه گیری شد. بدین منظور از منطقه نمونه رسوب نیز جمع آوری گردید. نمونه ها در آزمایشگاه مطابق دستورالعملMOOPAM ، 1999هضم و غلظت فلز سرب )بر حسب میکروگرم برگرم وزن خشک( با دستگاه ICP-OES مورد سنجش قرار گرفت. نتایج ارتباط منفی بین غلظت سرب در بافت کبد و طول کل را نشان داد که می تواند به علت کاهش سرعت جذب نسبت به سرعت دفع در طول رشد ماهی باشد. اختلاف معنی داری بین دو جنس نر و ماده از لحاظ غلظت سرب در بافت کبد مشاهده نشد (0.05 p >) که بیانگر بی تاثیر بودن جنسیت در تجمع سرب است میانگین غلظت سرب در رسوب در مقایسه با استانداردهای بین المللیISQG کمتر بود.
Members of the genus Cryptosporidium are small coccidian protozoan parasites that infect the microvillous region of epithelial cells in the digestive and respiratory tracts of vertebrates. Several species of Cryptosporidium have been described and appear to be specific for a class of vertebrates: C. parvum, C. muris, C. felis, and C. wrairi infect mammals, C. baileyi and C. meleagridis infect birds, C. serpentis infects reptiles, and C. nasorum infects tropical fish.Fecal samples from 200 native turky randomly selected from 30 regions in Dezful, Iran, were examined to investigate the prevalence of Cryptosporidium infection. Cryptosporidium oocysts were identified by using the Ziehl-Neelsen modified staining technique in 4 of 200 turky . Overall prevalence of infection was 2%, Both sexes of turky were infected with Cryptosporidium parasites, but prevalences were higher in male.
