Pseudomonas septicaemia encountered in some ornamental fishes

ABSTRACT

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
