Open AccessThe first non-mammalian CXCR5 in a teleost fish: molecular cloning and expression analysis in grass carp (Ctenopharyngodon idella)
Chemokines, a group of small and structurally related proteins, mediate chemotaxis of various cell types via chemokine receptors. In mammals, seven different CXC chemokine receptors denoted as CXCR1 to CXCR7 h...

Gene cloning and functional analysis of glycosaminoglycan-degrading enzyme chondroitin AC lyase from Flavobacterium columnare G4
The chondroitin AC lyase gene, cslA, was cloned for the first time from the fish bacterial pathogen F. columnare G4. From the first transcription initiation site, the cslA extends 2620 nucleotides to the end of t...

Characterization of two genes encoding leucine-rich repeat-containing proteins in grass carp Ctenopharyngodon idellus
The cDNAs and genes of two different types of leucine-rich repeat-containing proteins from grass carp (Ctenopharyngodon idellus) were cloned. Homology search revealed that the two genes, designated as GC-GARP and...

Scanning electron microscopy of Aspidogaster ijimai Kawamura, 1913 and A. conchicola Baer, 1827 (Aspidogastrea, Aspidogastridae) with reference to their fish definitive-host specificity
Two species of aspidogastreans, namely Aspidogaster ijimai and A. conchicola, were studied by scanning electron microscopy. In nine lakes and an old river course, the Tian’ezhou oxbow, investigated in the flood p...

Is the genus Digramma synonymous to the genus Ligula (Cestoda: Pseudophyllidea)?
The genus Digramma (Cestoda: Pseudophyllidea) described by Cholodkovsky in 1915 differs from the genus Ligula only by the number of the reproductive organs per proglottis. However, the occurrence of transitional ...
