[Changes in the electrolyte composition of the blood and muscles in carp infection with Ichthyophthirius multifiliis (Ciliata, Ophryoglenidae)].

A study of the electrolytic contents of blood serum, erythrocytes and muscles of carp infected with Ichthyophthirius multifiliis was carried out. Whatever the infection intensity, a characteristic increase in the cations K+ and Na+ ratio in the plasma and muscles of infected fishes takes place. The above dependence, which is expressed in the intensification of active ions transport, is associated with mobilization of organism's protective functions.
