Motile aeromonas septicaemia and other aeromonad infection encountered in coloured fish

Aeromonas hydrophila, Aeromonas sobria and Aeromonas salmonicida showed a percentage of infection 15.92%. 4.3% and 16.72% respectively in present study. The clinical signs and pathological alteration associated with these bacterial infection of fish, fin and tail rot, haemorrhagic septicemia and ulcerative disease were recorded. Induction of experimental infection by these isolates to determine their pathogenicity to Tilapia sp, Catfish, Angelfish, GuppyFish, Veiltailgoldfish and Swordtailfish were undertaken

Infection of coloured fish by staphylococcus epidermidis

Staphylococcus epidermidis showed 14.4% the percentage of infection in coloured fish. The clinical signs and pathological alteration associated with these bacterial infection were in form of ascitic fluid in abdominal muscle wall, eye damage-exophthalmia and ulcers. Induction of experimental infection by these isolates to determine their pathogenicity to Tilapia sp, Catfish, Guppyfish and Veiltailgoldfish were undertaken

Pseudomonas septicaemia encountered in some ornamental fishes

The present study found that the infection rate of Pseudomonas septicaemia rate was 8.56% and 4.89% respectively, which was mainly caused by Pseudomonas fluorescence and Pseudomonas anguilliseptica. The clinical signs and pathological alterations associated with these bacterial infections, of fish were represented as fin and tail rot, haemorrhagic septicemia and ulcerative lesions. Induction of experimental infection by such isolates to determine their pathogenicity to Tilapia, Catfish, Angelfish and Swordtailfish were undertaken. Also, the biogram of both bacterial isolates was carried out, and revealed that Pseudomonas fluorescence was more sensitive to Enrofloxacine, Streptomycin, Doxycycline, Tobramycin and Tetra-cycline.While Pseudomonas anguilliseptica more sensitive to Neomycin, Oxytetracycline and refamycin
