“…Concerning inter-specific differences, they have been documented for C. shasta (Bartholomew, 1998) and for M. cerebralis (Hedrick et al, 1998;Blazer et al, 2004) among salmonid species. Based on epizootiological data, Sugiyama et al (1999) indicated that amberjack (Seriola dumerili) was less susceptible to Kudoa amamiensis than yellowtail (Seriola quinqueradiata). Data obtained from proliferative kidney disease (PKD) experimental infections indicate that the development of the parasite and the severity of the disease may vary with host salmonid species (Arkush & Hedrick, 1990).…”

Summary :Myxozoan parasites are responsible for important economic losses among fisheries and aquaculture industries, and hence the high interest in studying the immune response of fish against them. The most important data available concerning the immune response of fish against myxosporeans are reviewed, with emphasis on the different innate and adaptive immune mechanisms, their relationship with natural and acquired resistance and the strategies to control and prevent myxosporoses. Cellular effectors (lymphocytes, granulocytes, phagocytes, non-specific cytotoxic cells, rodlet cells) and humoral factors (lysozyme, peroxidades, antiproteases, complement, specific antibodies) have been examined for several myxosporoses, and some immune relevant genes have been studied. This information will be crucial for the future development of vaccines and other preventive strategies such as immunomodulation and selection of disease-resistant strains

“…To enforce the quarantine policy rigorously, molecular-based detection methods will be useful for sensitive diagnosis of parasites even from live and asymptomatic fish (Andree et al, 1998;Fox et al, 2000). Selection of disease-free sites (avoidance of infected waters) is worthy of consideration, as some myxozoans have only a limited geographical distribution (Hendrickson et al, 1989;Sugiyama et al, 1999).…”

“…Since then, this disease has been assumed as a local disease of these areas and consequently fish farm ers in this district have abondaned yellowtail culture . However, Sugiyama et al (1999) demonstrated that the geographic distribution of K. amamiensis was narrower than previously believed and limited specifi cally to a local area (Motobu area) within the Okinawa main island. It is still unknown why the enzootic areas of this parasite are restricted.…”

“…The limitations of these conventional detection methods (microscopic detection of spores) lies in their inability to detect early myxosporean infections. Formation of K. amamiensis spores requires as long as 3 months (Sugiyama et al, 1999), and presporogonic stages have not yet been characterized.…”
