| taxonomic status of syngamus nematodes parasitizing passeriform hosts from central europe: morphological, morphometric and molecular identification. | the systematic position and validity of species within genus syngamus have always been controversial. in this present work, we evaluated the taxonomic status and phylogenetic relationships between three species of syngamus nematodes (syngamus trachea, syngamus taiga and syngamus merulae) and one taxa, determined only to the generic level, collected from respiratory tracts of passeriform hosts from central europe using newly obtained sequences of 2 nuclear markers (internal transcribed spacers 1 ... | 2016 | 27353021 |
