Abstract:

The Content of free amino acids in homogenates of unfed adult Hyalomma asiaticum was studied by fine-layer, two-dimensional chromatography in silica gel KCK. Individuals infested with and free from rickettsia C. Burneti and D. Sbiiticus were examined. 25 nynhydrin-positive smears were recognized on acids aspartic acid, glutamine acid with lysine and ornithine, atginine, serine, glycine, asparagine, beta-alanine, hydroxpoline, hystidine, threonine, alpha-alanine, tyrosine, valine, leucine with isoleucine and methionine, phenylalanine, tryptophan. Constant differences existed between males and females in the content of free amino acids. It was established that in ticks infested with rickettsia the content of alpha-alanine is considerably decreased, the content of one of the unidentfied nynhydrin-positive components is increased and concentrations of some other amino acids are changed slightly.
