Myxosoma cerebralis: Detection of circulating antibodies in infected rainbow trout (Salmo gairdneri)
Circulating antibody against spores of Myxosoma cerebralis has been detected for the first time in rainbow trout ( Salmo gairdneri ) affected with whirling disease. An indirect fluorescent antibody test (IFAT) was employed for detection of trout immunoglobulin. Most sera of fish from an infected experimental group were found to give a positive reaction in the IFAT, while the majority of specific-pathogen-free control sera gave no reaction. Reagent preparation as well as staining and evaluation procedures are given. These results provide additional information for understanding the host/parasite relationship and offer a potential for development of a nondestructive serological test for whirling disease.
