“…Systemic antibody is possibly less important for protection from BGD in any case, because the organism appears to be primarily a gill pathogen, without systemic invasion (Speare et al 1991a). Systemic antibody may play a role, however, if gill surface antibody is partially derived from serum transudation, as has been proposed for antibody on other mucosal surfaces (Harrell et al 1976, Ourth 1980, or if gill damage is associated with BGD (Speare et al 1991a, b), allowing pathotopic potentiation.…”

“…In addition, exposure to antigen has been shown to stimulate an antibody response at more than one mucosal site (Rombout et al 1986), as well as systemically, supporting the concept of a common mucosal immune system. The relationship between the rnucosal and systemic responses is complex, however, because in some cases only one type of response is detectable (Fryer et al 1976, Ward et al 1985, Lobb 1987, Sakai et al 1989 Inter-Research 1993 Velji et al 1991). In some teleosts it appears that the species of mucosal antibody may be structurally distinct from systemic antibody, although antigenically similar (Lobb & Clem 1981a, b).…”

“…The Gram-negative, motile, rod-shaped bacterium Vibrio ordalii is the causative agent of septicemia, which can result in fish death (Toranzo & Barja 1993). This microorganism was isolated for the first time from diseased salmon cultured in coastal waters of the American Pacific Northwest (Harrell et al 1976). Since its first isolation, V. ordalii has also been reported in Japan, Australia, New Zealand and Chile, mainly affecting salmonid farming (Wards et al 1991, Colquhoun et al 2004).…”

Survival behaviour and virulence of the fish pathogen Vibrio ordalii in seawater microcosms

Vibrio ordalii, the causative agent of atypical vibriosis, is a Gram-negative, motile, rod-shaped bacterium that severely affects the salmonid aquaculture industry. V. ordalii has been biochemically, antigenically and genetically characterized. However, studies on the survival behaviour of this bacterium in aquatic environments are scarce, and there is no information regarding its disease transmission and infectious abilities outside of the fish host or regarding water as a possible reservoir. The present study investigated the survival behaviour of V. ordalii Vo-LM-06 and Vo-LM-18 in sterile and non-sterile seawater microcosms. After a year in sterile seawater without nutrients, 1% of both V. ordalii strains survived (~10 3 colony-forming units ml −1 ), and long-term maintenance did not affect bacterial biochemical or genetic properties. Additionally, V. ordalii maintained for 60 d in sterile seawater remained infective in rainbow trout Oncorhynchus mykiss. However, after 2 d of natural seawater exposure, this bacterium became nonculturable, indicating that autochthonous microbiota may play an important role in survival. Recuperation assays that added fresh medium to non-sterile microcosms did not favour V. ordalii recovery on solid media. Our results contribute towards a better understanding of V. ordalii survival behaviour in seawater ecosystems.

“…A number of functions have been ascribed to the mucous layer, such as friction reduction (Pickering, 1974), protection against injury (Pickering and Richards, 1980), and ionoregulation. The mucus coat of fish also forms the primary barrier against infection (Pickering, 1974;Pickering and Macey, 1977;Ingram, 1980), and fish skin mucus may inhibit the growth of bacteria (Harrell et al, 1976;Fouz et al, 1990). In addition, the mucus plays an important role in various food processing activities (Murray et al, 1994;Vandenberg et al, 1994;Tibbetts, 1997;Gallagher et at, 2001).…”

The present study deals with the effect of temperature on the development of different tilapia species (O. niloticus, red tilapia, O. aureus and hybrid tilapia (O. niloticus x O. aureus)) during larval rearing, and its subsequent effect on larval growth and survival. The development of the gills and the digestive tract was investigated histologically and histochemically in the developing control and temperature-exposed larvae of different tilapia species. The exposure of different tilapia species larvae to moderate level of temperature (25-35ºC) with a mean of 30ºC greatly enhanced the development of gills and the digestive system of larvae as indicated by the quantitative and qualitative changes of the mucus composition from predominantly neutral to a mixture of neutral and acid mucosubstances, or acid mucosubstances occurred during the rearing period. This may be due to the direct effect of temperature on food intake and increasing of metabolism, enhanced the immunity of larvae or indirect effect of temperature on sex differentiation and producing high percentage of males which have rapid growth rate than females. Thus, rearing temperature directly or indirectly improved larval growth of different tilapia species, since a marked increase in both, length and weight of larvae occurred during the experimental period. In addition, temperature-exposed larvae also gave a significantly higher survival rate than that of control.It could be concluded that the exposure of different tilapia species larvae to a rearing temperature of 30ºC was effective for improvement of development and growth in a safe, simple and acceptable manner, as well as in a friendly approach to the environment.
