Antibacterial activity of crude extracts of culinary spices like Aniseed (Pimpinella anisum), Star anise (Illicum verum Hook fruit) and Cinnamon (Cinnamomum zeylanicum) against some of the common fish bacterial pathogens like Aeromonas hydrophila, Aeromonas salmonicida and Edwardsiella tarda were explored by finding minimum inhibitory concentration (MIC). A twofold serial dilution of compounds ...

A total of 50 strains of Aeromonas spp. were isolated from 50 water and fish samples, and identified biochemically and genetically. Biochemical characterization indicated that 20 out of 50 aeromonads were A. veronii, 19 were A. caviae, 9 were A. hydrophila and 2 were A. trota. Molecular identification of isolated aeromonads revealed restriction profile of four species i.e. A. sobria, A. media, ...

Like other pathogenic bacteria, Yersinia and Aeromonas species have been continuously co-evolving with their respective hosts. Although the former is a bonafide human pathogen, the latter has gained notararity as an emerging disease-causing agent. In response to immune cell challenges, bacterial pathogens have developed diverse mechanism(s) enabling their survival, and, at times, dominance over...

Outbreaks in fish of motile Aeromonad septicemia (MAS) caused by Aeromonas hydrophila have caused a great concern worldwide. Here, for the first time, we provide two complete genomes of epidemic A. hydrophila strains isolated in China. To gain an insight into the pathogenicity of epidemic A. hydrophila, we performed comparative genomic analyses of five epidemic strains belonging to sequence typ...

INTRODUCTION Between 2004 and 2007, a birth cohort of Egyptian children was analysed to evaluate the epidemiology of enteric diseases. METHODOLOGY A stool sample was collected from the study children every two weeks as well as whenever they experienced diarrhea. Samples were tested for routine bacterial pathogens as well as enteropathogenic viruses and parasites. A secondary goal of the study...

Persistence of Aeromonas hydrophila in aquatic environments is the principle cause of fish hemorrhagic septicemia. Protistan predation has been considered to be a strong driving force for the evolution of bacterial defense strategies. In this study, we investigated the adaptive traits of A. hydrophila NJ-35, a carp pathogenic strain, in response to Tetrahymena thermophila predation. After subcu...

Aeromonas infections are becoming a major risk factor in commercial aquaculture and it has been reported that a wide variety of fish and shellfish species are susceptible to this infection. In this study, 3 isolates of Aeromonas hydrophila were isolated from giant freshwater prawn (Macrobrachium rosenbergii) cultured in Kuala Pilah Simbilan Nigri in East Malaysia. Conventional and rapid identif...
