240 rainbow trout fingerlings weighting 16 gram were randomly allocated into three treatment groups including 0.5, 1.0and 1.5 gr/kg of Echinacea purpurea extract in food, and a control group (without EPE in food), each intriplicates for 60 days. At sampling times, some of hematological and biochemical parameters including C3 and C4 complements, oxygen free radicals, lysozyme activity, and other...
Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney o...
در این تحقیق جهت کنترل Streptococcosis با عامل Streptococcus iniae در ماهی قزلآلای رنگینکمان از Bacillus subtilis استفاده گردید. به طوری که از 2 گروه شامل کنترل و تیمار و سه تکرار برای هر گروه استفاده شد. درگروه کنترل، پروبیوتیک تجویز نشد اما در گروه تیمار، Bacillus subtilis با دوز107 سلول به ازای هر گرم غذا تجویز گردید. در روز چهل و پنجم تزریق داخل صفاقی Streptococcus iniae با دوز107×2 سلول...
Streptococcosis is an infectious bacterial disease of both homeotherms and poikilotherms. Among the Streptococcus species that infect marine animals, agalactiae has broadest host spectrum, including different aquatic organisms in freshwater environments. The common dolphin ( Delphinus delphis ) categorized as Endangered Mediterranean Sea. There are few reports a streptococcal infection D . , ca...
Ulva is a commercially important marine macroalga. It hosts both epiphytes and endophytes. The latter are assumed to protect through secondary metabolites. Previously, we demonstrated bioactive endophytes from macroalgae with great potential control diseases of aquaculture. In this study, introduced bacterial endophyte back into its original host ( sp.) survival over time in fresh freeze-dried ...
