Journal ArticleDOI
Diversity of the skin microbiota of fishes: evidence for host species specificity.
TL;DR: Analysis of skin microbiota of Gulf of Mexico fishes showed that the Proteobacteria was the predominant phylum in skin microbiota, followed by the Firmicutes and the Actinobacteria, which provided evidence for the existence of specific skin microbiota associated with particular fish species.
Journal ArticleDOI
Characterization of a diversity of tetraphyllidean and rhinebothriidean cestode larval types, with comments on host associations and life-cycles.
TL;DR: This is the first published study that approaches the elucidation of marine tapeworm life-cycles by incorporating morphological, molecular biological and phylogenetic methods using specimens collected on a regional scale and from wild-caught hosts from four metazoan phyla.
Journal ArticleDOI
Catfish hybrid Ictalurus punctatus × I. furcatus exhibits higher resistance to columnaris disease than the parental species.
TL;DR: Under experimental conditions, C×B hybrids were significantly more resistant to columnaris disease caused by the highly virulent strain of F. columnare BGFS-27 (genomovar II) than channel catfish and blue catfish.
Journal ArticleDOI
Adhesion dynamics of Flavobacterium columnare to channel catfish Ictalurus punctatus and zebrafish Danio rerio after immersion challenge.

TL;DR: The results of the present study show that particular strains of F. columnare exhibit different levels of specificity to their fish hosts and that adhesion to fish tissues is not sufficient to cause columnaris disease.
Journal ArticleDOI
Community Structure of Skin Microbiome of Gulf Killifish, Fundulus grandis, Is Driven by Seasonality and Not Exposure to Oiled Sediments in a Louisiana Salt Marsh
TL;DR: Overall, the high similarity observed between the microbiomes of individual fish observed during this study posits that skin and mucus of Gulf killifish have a resilient core microbiome.
