Abstract：
:The natural reservoirs and biological characteristics of pathogenic populations of both subspecies of Photobacterium damselae in aquatic habitants remain unclear because of difficulties in obtaining pathogenic strains from the environment. In the present study, we assessed the occurrence of Photobacterium damselae subsp. piscicida and Photobacterium damselae subsp. damselae , considered to be the causative agent of past epizootic outbreaks in mullets collected in the river Magra, Italy. Two hundred and seventy-eight mullets were collected during a period of two years (2008-2009) and analyzed using multiplex PCR. During this period, 57% of fishes were positive for Photobacterium damselae subsp. piscicida and 37% for Photobacterium damselae subsp. damselae, with an higher presence in summer months although none of PCR-positive mullets showed clinical signs of disease. Our results indicate that the two micro-organisms are widespread in the population of mullets studied, and this could be a possible cause for outbreaks in favourable environmental conditions.
