Streptococcus iniae has emerged as an important fish pathogen over the last decade in farmed rainbow trout in Iran. The main objective of this study was to evaluate the pathogenicity of S. iniae in Poecilia reticulata. Atotal of 60 apparently healthy P. reticulata were obtained from ornamental fish pet store and injected intraperitoneally with 1.5×106 cfu of bacteria. For 14 days after challenge, the rate of mortality and clinical signs were recorded. The first clinical signs was observed in challenged fish 48 hrs after injection of S. iniae and first mortality was observed 72 hrs after injection. No significant differences in mortality and clinical signs between both sexes were observed. Streptococcus iniae was collected from internal organs of fishes challenged, and was confirmed using the conventional biochemical tests and PCR. It is concluded that, P. reticulata is susceptible to streptococcosis and can play an important role in transmission of the disease to other ornamental fish species and also cultured fish.
