Capacity of Vibrio fluvialis (Lee, 1981) to produce disease in goldfish (Carassius auratus, L.)

Specimens of Carassius auratus were injected intramuscularly with different infectives doses of Vibrio fluvialis to prove the capacity of this pathogen for generating diseases in aquatic organisms, as well as to establish the corresponding LD sub(50) and to know whether these bacteria have the capacity to infect the cultivated fish through water from ponds, or if a live host is needed to produce infection. The etiological relationship between V. fluvialis and its host was established. Concurrently, the clinical forms of this infection were characterized as archetypical response, i.e. focal dermomyonecrosis concomitant with acute bacterial septicemia. The signs and lesions were a particular feature of vibriosis and furunculosis. This pathogen was unable to generate disease when the infection was experimentally induced through water from aquaria.
