In many guppy Poecilia reticulata farms in the vicinity of Bangkok, diseases have caused longlasting fish death and consequently large cumulative mortality. Diseased guppies were collected and subjected to histopathological analysis. The analysis revealed systemic granulomatosis as a remarkable histological sign. Rod-shaped bacterial cells with strong acid-fastness were found in the granulomas....

Sparse information is available on the virulence factors of Aeromonas strains isolated from diseased fish, from the environment, and from humans. In the present study, 52 Aeromonas isolates obtained from epizootic ulcerative syndrome (EUS) lesions in fish, from the aquatic environment, and from children with diarrhea in Bangladesh were identified by biochemical phenotyping (i.e., PhenePlate [Ph...

The aim of present study was to monitor the presence of Trichodina sp. in Rainbow trout, Oncorhynchus mykiss collected from various fish farms in the western provinces of Iran during January, 2013January, 2014. Out of 675 sampled fish 335, (49.16%) were infested with Trichodina. The highest prevalence was observed in the spring and winter followed by autumn and summer. In general, the intensity...

In late 2006 an unusual ulcerative condition in wild fish was reported for the first time in Africa from the Chobe and upper Zambezi Rivers in Botswana and Namibia. Concern increased with subsistence fishermen reporting large numbers of ulcerated fish in their catches. In April 2007 the condition was confirmed as an outbreak of epizootic ulcerative syndrome (EUS). The causative agent, Aphan...

The bacterium Pseudomonas angui1liseptica Wakabayashi & Egusa, originally described as a pathogen of eel in Japan, was isolated from diseased Atlantic salmon Salmo salar, sea trout Salmo trutta, rainbow trout Salmo gairdneri, and whitefish Coregonus sp. in Finland. Biochemical tests showed that the Finnish isolates are similar to the Japanese strains except for the Tween 80 reaction. Serologica...

Herein, we isolated the pathogenic strain ZZ051 from hemorrhagic channel catfish (Ictalurus punctatus). Physiological and biochemical identification, 16S rRNA gene sequence analysis, MALDI-TOF-MS showed that was Aeromonas veronii. After artificial infection, diseased fish symptoms similar to natural disease, characteristics of bacteria reisolated tissues were same as those original indicating p...

Abstract World population is increasing at a tremendous rate so the demand for animal-based protein. Aquaculture promising industry that has potential to supply high quality protein mankind with minimum environmental impact. In past decade, aquaculture practices have been shifting from extensive intensive culture. To achieve maximum production per unit area, stocking densities are maintained in...

The aim of the study was to determine a considerable level mortalities occurred in rainbow trout fry (Oncorhynchus mykiss) cultured research hatchery located Marmara Region/Turkey. Totally 18 individuals (1-8 g) were investigated by using bacteriological and mycological methods. affected fish showed skin darkening, prolapses fungal mats at base fins. According morphological biochemical characte...
