We detected a novel strain of picornavirus from dead backyard ducks from Gilan province, In Iran. This new isolated was demonstrated a genome like picornavirus design, specifically Aalivirus (Avihepatovirus/Avisivirus-like virus). Usually, Aalivirus were observed in domestic ducks, turkey and chickens. Ten pooled feces samples were collected from samples. We implemented partial genome sequencing of VP1 gene. We nominated the new strain as duck Aalivirus isolate UT-Ebrahimi. Based on our investigation with phylogenetic tree, we considered this strain is a member of the Aalivirus genus of picornavirus. In this study, we demonstrated that the UT-Ebrahimi is 96.23 % similar to Pacific_black_duck_megrivirus_(MK204391.1).

International Journal of Molecular and Clinical Microbiology, Volume:8 Issue: 1, Winter and Spring 2018, PP 931 -935One of the most prevalent zoonotic diseases is toxoplasmosis, which is caused by an obligated intracellular parasite, Toxoplasma gondii, with a high global dissemination. Some species of birds are susceptible to T. gondii infection. To indirectly survey on , T. gondii contamination of the rural and wild ecosystem of Golestan Province, presence of T. gondii antibody was examined in serum sample of 60 domestic rural ducks (Anas platyrhynchos domesticus) and 40 long-legged buzzard (Buteo rufinus) by MAT.ResultsOut of 60 (33=male, 29=female) domestic ducks' serums, 38 (63.3%) samples (20 male and 18 female were diagnosed positive. There was no significant difference in the prevalence of anti-T.gondii antibody in male (60.6%) and female (62%) ducks. Anti-T. gondii antibody frequency was detected in 77.5% (31 positive cases) of the sampled long-legged buzzard. Anti-T. gondii antibody frequency in long-legged buzzard was significantly higher than domestic ducks. Conclution: High T. gondii contamination of long-legged buzzard indicates a high risk of T. gondii infection in wild carnivorous species of Golestan Province. Although, high levels of T. gondii contamination of sampled domestic ducks, highlight the importance of villagers' knowledge growth about the important role of birds and cats in the life cycle of T. gondii.Keywords: T. gondii, duck, long-legged buzzard, Golestan, Province}

مقدمهسالمونلاها اجرام میله ای کوتاه، گرم منفی، فاقد کپسول، هوازی و بی هوازی اختیاری هستند که در انسان سبب ایجاد مسمومیت غذایی می شود. در انتقال این بیماری، مواد غذایی خام با منشاء دامی به ویژه گوشت و تخم پرندگان حائز اهمیت فراوانی هستند. با توجه به اهمیت تخم اردک و بوقلمون در انتقال سالمونلوزیس و مصرف تخم اردک و بوقلمون های محلی و غیر صنعتی در منطقه، همچنین پی بردن به میزان آلودگی سالمونلایی مطالعه حاضر صورت پذیرفت.مواد و روش هابه منظور مطاله حاضر، 300عدد تخم اردک و بوقلمون های بومی جمع آوری و به آزمایشگاه منتقل گردید؛ درآزمایشگاه پس از نمونه گیری از سطح تخم های مورد برسی، پوسته آنها با اتانول80 درصد ضد عفونی و محتویات هر 5 عدد تخم اردک و بوقلمون به صورت جداگانه در یک بشر مخلوط گشته و پس از24 ساعت انکوباسیون در دمای C °37 با سوآب در آبگوشت سلنیت- F تلقیح گردید. نمونه از محیط سلنیت-F به آگار سالمونلا- شیگلا منتقل شد و پس از انکوباسون در C °37 ازنظر کلنی های مشکوک به سالمونلا بررسی شدند. کلنی های مشکوک در محیط های TSI و لیزین دکربوکسیلاز تلقیح و باکتری هایی که دارای واکنش های مربوط به سالمونلا بودند بوسیله آزمایش PCR با پرایمرهای اختصاصی برای سالمونلاها و سروتیپ های سالمونلا انتریتیدیس و سالمونلا تیفی موریوم مورد بررسی قرارگرفتند.یافته هااز مجموع 300 تخم اردک و بوقلمون مورد بررسی پوسته 7 مورد (2/ 3 درصد) آلوده به سالمونلا بود. از 7 مورد آلودگی 1 مورد پوسته تخم بو قلمون آلوده به سالمونلا تیفی موریوم بود. از طرفی 6 مورد آلودگی مربوط به پوسته تخم اردک های مورد مطالعه بود که همگی از سروتیپ سالمونلا تیفی موریوم بودند.بحث و نتیجه گیریبا توجه به مطالعه حاضر و تحقیق سایرمحققین در مجموع می توان نتیجه گرفت میزان عفونت سالمونلا در تخم اردک و بو قلمون نسبت به تخم ماکیان کمتر بوده و به نظر می رسد انتقال عمودی سالمونلا در بوقلمون و اردک کمتر از ماکیان باشد.

Raw food of animal origin, particularly meat and eggs of birds have important role in the transfer of this disease. Since duck and turkey eggs are very important in the transmission of Salmonellosis and consuming of local and non-industrial eggs of ducks and turkeys in this area is common, the present study was performed to clarify the prevalence of salmonella contamination.Materials And MethodsIn the present study, 300 native duck and turkey eggs were collected and transferred to the lab. In laboratory after sampling from surface of the eggs shell were disinfected with 80% ethanol and contents of 5 duck and turkey eggs, sparately mixed in special dishes. After 24 hr incubation at 37°C with a swab in selenite - F broth were inoculated. Samples were transferred to Salmonella - Shigella agar from selenite-f environment. After incubation in 37°C, colonies suspected to Salmonella were evaluated. Suspicious colonies in the TSI and lysine decarboxylase environments were inoculated. And bacteria that had reactions related to Salmonella, were studied by PCR with specific primers for Salmonella and serotypes of Salmonella Enteritidis and Salmonella Typhimurium.ResultsA total of 300 eggs of ducks and turkeys, 7 cases (2.3%) were contaminated with Salmonella, and from 7 unclean egg s shell, 1 case of turkey egg shell (0.66%) was infected with Salmonella Typhimurium. And 6 duck eggs shell (4%) were infected, that all of the serotypes were Salmonella Typhimurium.ConclusionRegarding the present study, and other researches, it can be concluded that the Salmonella infection in the duck and turkey eggs were less than poultry eggs and it seems that vertical transmission of Salmonella in the turkeys and ducks was less than poultry.Keywords: Salmonella, Egg shell, Duck, Turkey} -
IntroductionIn order to study the morphogenetic role of cell death in the development, a series of comparative studies on the structure of the interdigital membrane of chick (with free digit) and duck (webbed digits) embryos was done.Materials And MethodsChick embryos ranging from 6.5 to 10 days of incubation (stag 30-36 H-H) and duck embryos ranging from 8.5 to 12 days of incubation at 12 hour intervals were included in the study. The techniques used in this project were: Vital Staining, Light Microscopy (LM), Transmission Electron Microscopy (TEM).ResultsThe results of this study showed that interdigital cell death existed both chick and duck embryos, but the intensity of the degenerative change in duck was lower than that of the chick. This relative decrease in the cell death accounts for the survival of the interdigital webs in ducks.ConclusionThe conclusion of this investigation that the interdegital cell death has certain role in separating the digits as well as sculpturing of limb.Keywords: Cell death, Limb development, Chick, Duck}
