“…Regarding other intrafilamental forms, observations on the chondreal type have been presented, apart from those reported in this paper, in the case of the species Myxobolus shadgani (Molnár et al 1996). The cases reported by Paperna (1973), Sakiti et al (1991), and Yokoyama et al (1997), where the tissue affinity of parasites with relatively well-defined locations was not discussed in detail, probably also corresponded to this type of development.…”

“…The intralamellar location seems to be the most common in the case of Myxobolus species as well, since the species Myxobolus dujardini, M. koi, M. hungaricus, M. bramae, M. macrocapsularis and M. margitae develop in this manner (Mitchell 1989, Yokoyama et al 1997, Molnár & Baska 1999, Molnár & Székely 1999, Molnár 2000b, and the Myxobolus species studied by Sanaullah & Ahmed (1980) also follows that type of development. Data on interlamellar location (i.e.…”

In addition to the morphological and size characteristics of the spores, indicating the exact location and tissue specificity is also essential for differentiation of the large number of species belonging to the group of gill-parasitic fish, the myxosporeans. According to the observations of the present author, Myxobolus, Henneguya and Thelohanellus species are characterised by strict tissue specificity, and species showing affinity to the epithelium, connective tissue, cartilage or vascular tissue usually occur in a strictly defined location within the gill apparatus. Some of the species typically form plasmodia in the lamellae of the gill and others in the gill filaments. Yet other species develop their plasmodia at the base of the gill filament or in the gill arch. Instead of the generally accepted but misleading terms 'intra-' and 'interlamellar', the present author distinguishes interlamellar-epithelial and intralamellar-vascular types in the case of plasmodia developing in the gill lamellae, and intrafilamental-epithelial, intrafilamental-vascular and intrafilamental-chondroidal types in the case of plasmodia developing in the gill filaments. Regarding site of development within the gill, the location of basifilamental plasmodia and that of plasmodia developing in the cartilaginous matrix, connective tissue or blood vessels of the gill arch are well distinguishable from the above types.
