BACKGROUND The present investigation was an endeavor into the elucidation of the disease-causing pathogen of streptococcosis in Nile tilapia (Oreochromis niloticus) in Egypt affecting adult fish cultured and wild fish in the Nile river. Fish were obtained from commercial fishermen, collected as part of their routine fishing activities. The researchers observed the routine fishing process and se...
Abstract Background Streptococcosis is a major bacterial disease in Nile tilapia that caused by Streptococcus agalactiae infection, and development of resistant strains represents sustainable approach towards combating this disease. In study, we performed controlled trial on 120 full-sib families to (i) quantify characterize the potential genomic selection for survival S. infection tilapia, (ii...
Multiple infections of several bacterial species are often observed under natural farm conditions. The would cause a much more significant loss compared to single infectious agent. Vaccination is an essential strategy prevent diseases in aquaculture, and oral vaccination has been proposed as promising technique since it requires no handling the fish easy perform. This research attempts develop ...
استرپتوکوکوزیس(Streptococcosis( و لاکتوکوکوزیس (Lactococcusis) از جمله بیماریهای باکتریایی ماهیان هستند که انواع مختلف ماهیان وحشی و پرورشی به ویژه قزلآلای رنگین کمان را به صورت انفرادی و همهگیر در معرض خطر قرار داده و خسارات اقتصادی قابل توجهی را به دنبال دارند. در تحقیق حاضر، تعداد 60 قطعه ماهی با علائم استرپتوکوکوزیس/ لاکتوکوکوزیس جمعآوری و از آنها نمونهبرداری و کشت میکروبی انجام شد. ...
The number of fishes were conducted a series of bacteriological examinations to confirm the clinical symptoms that appeared and led to streptococcal infection. Results of the external examination from two moribund red tilapia found the hemorrhagic traces in some parts of the body such as the cranial area near the mouth, eyes, operculum, and some body parts and erosion on the tail, pectoral, and...
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...
Background & Objectives: Sterpococcosis/lactococcosis is an economically important zoonotic disease in aquaculture industry particularly in farmed rainbow trout. The annual loss due to the disease is tens millions US dollars. This descriptive study was aimed to identify the regional distribution of these economically important bacterial diseases in 50 farmed trout in Charmahal-va-Bakhteyari (25...
The administration of probiotics via live feeds, such as Artemia and rotifers, has gained significant attention. Moreover, indiscriminate use antibiotics in conventional aquaculture practices order to prevent or control disease outbreaks resulted the occurrence residues antimicrobial resistance. Thus, application eco-friendly feed additives, probiotics, a safer alternative received increasing a...
