biostudies-literatureUnknown5(3)Patra AThe present study characterized <i>Argulus</i> spp. infecting the cultured carps using 18S rRNA gene sequences, estimated the genetic similarity among <i>Argulus</i> spp. and established their phylogenetic relationship. Of the 320 fish samples screened, 34 fish (10.6%) had <i>Argulus</i> infection. The parasitic frequency index (PFI) was observed to be high (20%) in <i>Hypophthalmichthys molitrix</i> and <i>Labeo bata</i>. The frequency of infection was high in September (PFI: 17%) and October (PFI: 12.9%). The 18S rRNA sequences of five <i>A. bengalensis</i> (KF583878<i>,</i> KF192316, KM016968, KM016969, and KM016970) and one <i>A. siamensis</i> (KF583879) of this study showed genetic heterogeneity and exhibited 77-99% homology among the 18S rRNA gene sequences of <i>Argulus</i> spp. of Molecular biology research communications156-166https://www.ebi.ac.uk/biostudies/studies/S-EPMC5219910biostudies-literatureMolecular characterization of <i>Argulus bengalensis</i> and <i>Argulus siamensis</i> (Crustacea: Argulidae) infecting the cultured carps in West Bengal, India using 18S rRNA gene sequences.PMC5219910Banerjee SPatra AJoardar SNMondal AAbraham TJAdikesavalu HfalseMolecular characterization of <i>Argulus bengalensis</i> and <i>Argulus siamensis</i> (Crustacea: Argulidae) infecting the cultured carps in West Bengal, India using 18S rRNA gene sequences.The present study characterized <i>Argulus</i> spp. infecting the cultured carps using 18S rRNA gene sequences, estimated the genetic similarity among <i>Argulus</i> spp. and established their phylogenetic relationship.
