“…In this analysis, only 76 % (86 out of 113) strains exhibited this index profile. Aberrant reactions for arginine dihydrolase, citrate utilization and Voges-Proskauer test have already been observed by Kent et al (1982), Hawke et al (1987) and Candan et al (1996). Based on these findings, it is concluded that the API 20E test system is not always a useful tool for the identification of P. damselae subsp.…”

The taxonomic position of Photobacterium damselae subsp. piscicida, the causative agent of fish pasteurellosis, is controversial as this organism has also been described as ' Pasteurella piscicida '. To clarify the taxonomic position of the pathogen, a total of 113 P. damselae subsp. piscicida strains and 20 P. damselae subsp. damselae strains, isolated from different geographical areas and from the main affected fish species, were analysed using 129 morphological and biochemical tests, including the commercial API 20E and API CH50 test systems. For comparison, the type strains of other Photobacterium species (i.e. Photobacterium leiognathi and Photobacterium angustum) were included in the analyses. The results were statistically analysed by unweighted pair group average clustering and the distance between the different clusters was expressed as the percentage disagreement. The analyses showed that, based on morphological and biochemical identification tests, P. damselae subsp. piscicida is related to other Photobacterium species. However, it is clearly distinguishable from P. damselae subsp. damselae and no phenotypic evidence was found to include P. damselae subsp. piscicida as a subspecies in the species P. damselae.

“…piscicida is the causative agent of pseudotuberculosis in several cultured fish species, such as young black seabream, oval filefish, gilt-head seabream and seabass (Ohnishi et al, 1982;Yasunaga et al, 1984;Toranzo et al, 1991;Balebona et al, 1992). This disease has caused important economic losses in the aquaculture industry of Japan (Ueki et al, 1990;Nakai et al, 1992), United States (Hawke et al, 1987), and Europe (Balebona et al, 1992). Magariñ os et al (1992) have demonstrated that the strains of P. damsela subsp.…”

“…piscicida (formerly Pasteurella piscicida, Gaulthier et al, 1995), the causative agent of pseudotuberculosis or pasteurellosis, is responsible for extensive losses in aquaculture. Pasteurellosis has been reported in wild and cultured marine fish species in Japan (Kubota et al, 1970;Ueki et al, 1990), USA (Sniezsko et al, 1964;Hawke et al, 1987) and more recently in Europe, mainly affecting sea bass and gilthead sea bream (Toranzo et al, 1991;Balebona et al, 1992).…”

Superoxide dismutase and catalase in Photobacterium damselae subsp. piscicida and their roles in resistance to reactive oxygen species

Photobacterium damselae subsp. piscicida (formerly Pasteurella pisckida) is the causative agent of pasteurellosis or pseudotuberculosis in warm water marine fish. Enzymes which neutralize reactive oxygen species, produced during aerobic metabolism or during respiratory burst in fish macrophages, are important virulence factors in many pathogens. This study characterizes a periplasmic superoxide dismutase (SOD) and a cytoplasmic catalase in P. damselae. Purification and partial amino-terminal sequencing confirmed the SOD to be iron-cofactored, with a high degree of homology to other bacterial FeSODs. The SOD was common to all strains analysed in terms of type, location and activity, whilst the catalase varied in activity between strains. The catalase was constitutively expressed, but the SOD appeared to be repressed under low oxygen conditions. In spite of the presence of a periplasmic SOD, P. damselae was susceptible to killing by exogenous superoxide anion generated in a cellfree system. Addition of exogenous SOD to this system did not abolish the bactericidal eft: ect; however, addition of catalase was protective. These results suggest that lack of periplasmic catalase may be implicated in susceptiblity t o killing by reactive oxygen species.
