Fish pathogenic pseudomonads include Pseudomonas anguilliseptica, Ps. baetica, Ps. chlororaphis, Ps. fluorescens, Ps. koreensis, Ps. luteola, Ps. plecoglossicida, Ps. pseudoalcaligenes and Ps. putida, which are the causes of Sekiten byo (= red spot), a disease of wedge sole without external or internal disease signs, distended abdomen and haemorrhaging on the body surface, fin/tail rot with or without the presence of external haemorrhaging, haemorrhagic septicaemia, bacterial haemorrhagic ascites of ayu, extensive skin lesions, and exophthalmia with external ulceration, respectively. Molecular diagnosis has been achieved with Ps. anguilliseptica. Formalin inactivated whole cell vaccines have been developed for Ps. anguilliseptica and Ps. plecoglossicida.
