The aim of this study was to investigate the main cause of green terror mass losses in an ornamental fish breeding center in Nazarabad, Alborz province. Following chronic and continuous losses of mature green terrors with clinical signs including white feces hanging from the anus, the fish were sampled between June 2021 and July 2021. The fish were packed in water-filled polyethylene bags and transported to the Ornamental Fish Clinic, Faculty of Veterinary Medicine, University of Tehran. In macroscopic examinations, cachexia and paleness of the fish were evident. In order to investigate ectoparasitic infestations, wet smears were prepared from skin and gills, and examined under a light microscope. However, no parasitic infection was observed. In addition, the fish were euthanised, necropsied, and internal organs such as the intestine were examined. Microscopic examination of the intestine showed a heavy infection with mature Capillaria sp. and the barrel-shaped eggs. In the present study, the severity of Capillaria infection was very high and determined to be the main cause of losses. In order to treat the other fish in the population, levamisole was administered for 48 h every 7 days for 28 days. After re-examination, fish losses completely stopped, and no infection was observed after 28 days.","PeriodicalId":55306,"journal":{"name":"Bulletin of the European Association of Fish Pathologists","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49222331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 96-h LC50 was 74.78 mg L-1 with lower and upper confidence limits of 62.8 and 89.06 mg L-1, respectively. All fish exposed to 30 to 180 mg L-1 exhibited rapid movement, faster opercular activity and erratic swimming whereas at higher concentrations (90 mg L-1 to 180 mg L-1) fish showed additional behavioral changes such as loss of balance, lethargy, gulping for air and respiratory distress. Water quality parameters were within the recommended acceptable limits. This LC50 value can be used as a baseline reference to generate an effective concentration of garlic for future prophylaxis and treatment for parasitic, viral and bacterial infection in grouper.","PeriodicalId":55306,"journal":{"name":"Bulletin of the European Association of Fish Pathologists","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47947010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fish were starved for 2 days then fed with OTC medicated diet (75mg/kg fish/day) or OXA medicated diet (30 mg/kg fish/day) 3 times a day for 10 successive days at 2% body weight and thereafter switched to regular diet for 45 days.

Phages for phage therapy can be isolated, identified and enumerated using a Double-Layer Agar (DLA) technique. While some phages form large and well-defined plaques that can be enumerated when plated with the DLA technique, some produce small and turbid plaques that are difficult to detect and count. A phage, Aeromonas phages-T65, was isolated from Aeromonas hydrophila, which formed small and turbid plaques making it hard to count. The use of antibiotics and chemicals have been suggested as a way to increase plaque size for easy detection and enumeration of phage plaques. To increase the plaque size of Aeromonas phages-T65, antibiotics and glycerol were added to the culture media, and tested at different concentrations. Application of penicillin-streptomycin and/or glycerol showed an increase in plaque size and the biggest improvement in plaque size were observed using either 40 U/μl penicillin-streptomycin or a 5 % glycerol in the top agar layer of the DLA technique. These findings suggest that such modifications could be implemented into the standard DLA overlay method to investigate new Aeromonas phages for the development of phage therapy against Aeromonas spp. in aquaculture.","PeriodicalId":55306,"journal":{"name":"Bulletin of the European Association of Fish Pathologists","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42484209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
