Qualitative analysis of substances excreted by Isoparorchis hypselobagri (Trematoda) during aerobic in vitro culture.

Isoparorchis hypselobagri from the swim bladder of the catfish, Wallago attu was aerobically cultured in vitro. The dialyzed incubate was microchemically analysed for either individual or group of compounds excreted by the parasite. Amino acids, amines, amides, ammonia, aldehyde, glycine, alpha-alanine, tyrosine, alpha-aminocarboxylic acids, haemoglobin, nitrogen, reducing materials, and lactic, pyruvic, succinic, propionic and acetic acids were found in the incubate, but acetaldehyde, formaldehyde, O-dioxo and oxomethylene, and formic acid were not detected.
