Muscles of the bream Abramis brama (L.) infected and not infected with plerocercoids of L. intestinalis, as well as the plerocercoids constituted the material. In the studied material the content of water, proteins (biuret method), hydrocarbons (antron method) and lipids (Folch's method), as well as the qualitative lipid composition (thin layer chromatography on silicagel) were determined. The muscles of infected fish showed a slightly higher (by 1.6% fresh weight) water content and a slightly lower content of proteins, hydrocarbons and lipids (by 0.6%, 0.03% and 0.6°/o respectively). In the body of the plerocercoids the content of water and proteins was lower than in the host muscles (by 11% and 8% respectively), as well as that of lipids (by 2.6% and 2.7%), while the hydrocarbon content was much higher (16.7% for the plerocercoids, 0.06% for the host). It is interesting to note the high phospholipid content (31.2°/o) in the lipid pool of the plerocercoids, along with the simultaneous decrease of this fraction in the respective pool of infected bream. Besides, in the group of neutral lipids of the muscular tissue of the bream triglycerides form a significant part. The slight changes in the chemical composition of the muscles of infected fish, as compared with the relatively high level of their energy reserves (as triglycerides), suggest that the negative effect of the parasite on the physiological condition of its host is rather limited.
