| phylogeny and cocoon production in the parasitic leech myzobdella lugubris leidy, 1851 (hirudinidae, piscicolidae). | myzobdella lugubris is a commensal leech on crustaceans and a parasite to fishes, surviving predominantly in brackish waters throughout north america. specimens in this study were collected within the tidal zone of the delaware river basin (new jersey and pennsylvania). to compare regional m. lugubris specimens, defined characters were scored after dorsal and ventral dissections, and phylogenetic relationships were resolved using cytochrome c oxidase subunit 1 (co1), 12s ribosomal rna (rdna) and ... | 2018 | 29351062 |
| comparison of extracellular dnase- and protease-producing spoilage bacteria isolated from delaware pond-sourced and retail channel catfish (ictalurus punctatus). | spoilage of fishery products begins immediately following filleting due to microbial growth that degrades fish tissue quality prior to consumption. extensive research has been conducted to identify such bacterial populations. a better understanding of the mechanisms involved in fish spoilage is necessary as a novel remedy for microbial spoilage inhibition has yet to be established for fish tissue. the present study identified, for the first time, bacterial populations that produce extracellular ... | 2015 | 24931919 |
