چکیده مقاله :
شناسایی و بررسی های اپیدمیولوژیکی آلودگی های قارچی در مراکز تکثیر اهمیت زیادی در پیشگیریاز مرگ ومیر و ضررهای اقتصادی متعاقب آن دارد. در بررسی حاضر 5 مرکز تکثیر قزل آلای رنگین کمان در استان آذربایجان غربی مورد بررسی قرار گرفتند. نمونه گیری بر اساس جداول استاندارد سازمان دامپزشکی ایران صورت پذیرفت. کیفیت آب مراکز نیز مورد آزمایش قرار گرفت. برای کشت قارچ ها از محیط سابارو دکستروز آگار استفاده شد، سپس به روش مشاهده میکروسکوپی با بررسی اندام های تولیدمثلی قارچ ها، نوع آن ها شناسایی گردید. در بررسی حاضر از 5 مرکز تکثیر مورد مطالعه، 4 جنس مختلف از قارچ های ساپروفیتی جدا گردید که به ترتیب عبارت بودند از: ساپرولیگنیا، پنی سلیوم، آسپرژیلوس و آچلیا. جنس های ساپرولیگنیا با 48/1±8/7 درصد بیشترین و آچلیا با 83/0±8/0 درصد کمترین موارد آلودگی را نشان دادند. طبق یافته های این مطالعه، مراکز تکثیر لارو ماهی قزل آلای رنگین کمان استان آذربایجان غربی از لحاظ آلودگی قارچی در وضعیت بهداشتی مطلوبی به سر نمی برند. با توجه به این که کیفیت آب مراکز تکثیر دارای کیفیت قابل قبول بود، آلودگی قارچی احتمالاً در ارتباط با کیفیت آب نبوده است.
چکیده انگلیسی:
Identification and epidemiological survey of fungal infections at the hatcheries has great importance for prevention of mortalities and subsequent economic losses. In this survey, 5 rainbow trout hatcheries in west Azarbaijan province were investigated. Sample collection was conducted according to standards of Iranianveterinary organization. Water quality of the hatcheries was investigated as well. SDA (sabouraud dextrose agar) medium was used for fungal culture and identification of fungal type was based on microscopic examination of fungal reproductive organs. Four different genera of saprophytic fungi consisting of Saprolegnia sp., Penicillium sp., Aspergillus sp. and Achyla sp. were isolated from the 5 studied hatcheries. The genus Saprolegnia with 7.8±1.48% infection rate and Achyla with 0.8±0.83% infection rate had the highest and lowest prevalence respectively. Based on the results of this study, the sanitary conditions in hatcheries of west Azarbaijan province are not ideal with respect to fungal infections. Water quality of the hatcheries was acceptable therefore fungal infections are probably not associated with the water quality.
