  • Title: [New details of the life cycle of Myxobolus cerebralis according to the literature].
    Author: Prost M.
    Journal: Wiad Parazytol; 1996; 42(3):283-90. PubMed ID: 9012131.
    Abstract:
    The article comprises new details of the life cycle of Myxobolus cerebralis, the parasite of the skeleton of salmonids. Although this species has been known since 1903, its complete life cycle has remained unknown till now or it has comprised mistaken details. Recently EL Matbouli et al. (1995) have described the life cycle of this parasite with numerous new data. M. cerebralis provokes in salmonids (especially in rainbow trouts) the whirling disease and heavy economical losses. Therefore the article may be useful for Polish ichthyopathologists. Besides the new description of the life cycle of M. cerebralis the authoress of the article gives her own considerations on some topics connected with this life cycle, which still remain insufficiently explained. The considerations concern the mechanism of the specificity of the invasive stages of the parasite to two species of its hosts (Tubifex tubifex and Oncorhynchus mykiss) and also to tissue specificity, the possibility of better and more effective control of whirling disease in breeding conditions through the knowledge of the complete life cycle of the parasite, the pathogenic activity of the parasite on fish central nervous system in spite of the lack of its lesions noted by EL Matbouli et al. (1995). The authoress pays attention to the necessity of future studies on the mitotic and meiotic cleavages of the developmental stages of the parasite. She considers also if the very complicated life cycle of M. cerebralis determined during the long evolution of this species may be recognized as favourable feature for it.
