V. Barus et al., AMINO-ACID SPECTRA OF 2 NEMATODE SPECIES (NEMATODA, DRACUNCULOIDEA) PARASITIZING FISHES IN THE CZECH-REPUBLIC, Helminthologia, 35(1), 1998, pp. 7-11
The amino acid (AA) spectra of females of two nematode species are rep
orted: Anguillicola crassus - (Anguillicolidae), from the host Anguill
a anguilla and Philometra ovata - (Philometridae), from the host Abram
is brama. Seventeen AA, of these 11 essential AA (EAA) and 6 non-essen
tial AA (NEAA) were determined. Differences in quantitative values of
AA in the nematode species compared (A. crassus : Ph. ovaba) are stati
stically significant in 9 EAA and 4 NEAA. In the EAA set of A. crassus
the highest values are in methionine, valine and tyrosine, in that of
Ph. ovata in arginine, leucine and valine. In the NEAA set of both sp
ecies, the highest values were indicated by glutamic acid and aspartic
acid. Differences between both nematode species were found in proline
, alanine, glycine and serine (in respective hierarchic quantitative o
rder). In the species A. crassus the AA spectrum was examined in 3 gro
ups. The first sample (ACE) consisted of females in beginning maturati
on phase, the second sample (ACL) consisted of fully mature females wi
th embryonated eggs and fully developed sheathed larvae. The third sam
ple (ACT) consisted of both growing phases in nematodes (ACE + ACL). T
he comparison of the analysis results between ACE and ACL revealed sta
tistically significant differences in the quantitative values in 13 AA
.
