Isolation and Antibiotic Susceptibility of Aeromonas Hydrophila in a Carp (cyprinus Carpio) Hatchery Farm
نویسندگان
چکیده
The aim of this study was to describe a case of skin lesions with haemorrhaging in a carp (Cyprinus carpio) hatchery farm and to determine effective antibiotic treatments. In the macroscopic examinations of nine carp with haemorrhagic skin lesions, brown or red spotted skin changes of a varying degree were found, along their bodies. No lesions were observed in the internal organs. Pure cultures of Aeromonas hydrophila were isolated from the skin, kidney, heart, and liver of the carp. All of the isolates were found to be susceptible to danofloxacin, enrofloxacin, gentamicin, ciprofloxacin, neomycin, and trimethoprim-sulphamethoxazole and resistant to ampicillin, amoxicillin, amoxicillin/clavulanic acid, oxytetracycline, and streptomycin. Treatment of A. hydrophila infection was carried out by applying trimethoprim-sulphamethoxazole for 3 d at 10 g/ton of pool

Draft Genome Sequence of Aeromonas hydrophila Strain Ae25, Isolated from a Septicemic Moribund Koi Carp (Cyprinus carpio) in Sri Lanka
Motile aeromonad septicemia caused by mesophilic strains of Aeromonas hydrophila is a widespread problem in cultured freshwater fish. We announce here the draft genome sequence of the multidrug-resistant A. hydrophila strain Ae25, isolated from a koi carp (Cyprinus carpio) with motile aeromonad septicemia that was collected from an ornamental fish-breeding farm in Sri Lanka.

Aeromonas hydrophila is an important opportunistic pathogen that infects a variety of aquatic and terrestrial animals, including humans. We report here the draft genome sequence of A. hydrophila Ae34, a multidrug-resistant isolate from the kidney of a moribund koi carp (Ciprinus carpio koi) with signs of hemorrhagic septicemia.

Aeromonas infections are the most common bacterial disease of cultured fish in China. In this study, a gram-negative bacillus was isolated from the liver of diseased koi carp (Cyprinus carpio koi), and named strain KC-2. The results of morphological and biochemical tests, as well as phylogenetic analysis derived from 16S rRNA and gyrB sequences indicated that the isolated strain KC-2 was highly...
