The adhesion dynamics of Flavobacterium columnare to fish tissues were evaluated in vivo by immersion challenge followed by bacterial plate count and confirmatory observations of gill-adhered bacterial cells using scanning electron microscopy. Adhesion of F. columnare genomovar I (ARS-1) and II (BGFS-27) strains to skin and gill of channel catfish Ictalurus(More)
Kudoa hypoepicardialis n. sp. infects the space between the epicardium and the compact myocardium and, in intense infections, the pericardial chamber of man-of-war fish (Nomeus gronovii) (Nomeidae) (the type host), blue runner (Caranx crysos) (Carangidae), Warsaw grouper (Epinephelus nigritus) (Serranidae), Atlantic tripletail (Lobotes surinamensis)(More)
Adults of Lecithochirium floridense (Digenea: Hemiuridae) parasitized the stomach in each of 22 necropsied lionfish, Pterois cf. volitans (Scorpaeniformes: Scorpaenidae) (prevalence  =  100%, mean intensity  =  11), captured in the northwestern Atlantic Ocean off Beaufort, North Carolina (34°14.83'N, 76°35.25'W). This is the first report of a digenean from(More)
We present experimental data on susceptibility to columnaris disease, caused by the bacterium Flavobacterium columnare, in hybrid catfish (female channel catfish Ictalurus punctatus × male blue catfish I. furcatus) (C×B). Under our experimental conditions, C×B hybrids were significantly more resistant to columnaris disease caused by the highly virulent(More)
The family-group name for the “fish blood flukes” is unstable, with both “Aporocotylidae Odhner, 1912” and “Sanguinicolidae von Graff, 1907” in use for the single family. Although “Sanguinicolidae von Graff, 1907” (or. Graff, 1907.) has been a widely-accepted family-group name for the fish blood flukes subsequent to Yamaguti’s 1954 and 1958 synoptical(More)
Gill lesions associated with infections of Erpocotyle tiburonis (Brooks, 1934) (Monogenea: Hexabothriidae) on wild bonnethead sharks (Sphyrna tiburo (L., 1758) (Carcharhiniformes: Sphyrinidae)) were compared with those on aquarium-held ones using light and scanning electron microscopy. Uninfected gill filaments had slender, triangular, smooth-surfaced(More)
Branchotenthes robinoverstreeti n. gen. and n. ap. (Monogenea: Hexabothriidae) infects the gill filaments of the bowmouth guitarfish, Rhina ancylostoma Bloch and Schneider, 1801 (Rhynchobatidae) in the southwest Indian Ocean off Trafalgar, South Africa. The new species is most easily distinguished from other hexabothriids by the combination of having a(More)
Littorellicola billhawkinsi n. gen., n. sp. infects the myocardial lacunae of the ventricle and atrium of Florida pompano, Trachinotus carolinus in the northern Gulf of Mexico. It differs from other aporocotylid genera by the combination of having a body 10-30× longer than wide, a posterolateral body protuberance, lateral spine rows, an aspinous anterior(More)
Life-cycles of marine tapeworms of the orders Tetraphyllidea and Rhinebothriidea are poorly known primarily because their larvae typically lack species level, taxonomically distinguishing adult characteristics and using morphology they can be identified to genus, family or order only. This large-scale study conducted in the northern Gulf of Mexico includes(More)
Sanguinicolids, or fish blood flukes, infect the vascular system of both marine and freshwater fishes, and some act as serious pathogens of hosts in aquaculture. Blood flukes typically possess a relatively benign relationship with wild fishes; however, cultured hosts near appropriate intermediate hosts (i.e., snail, bivalve, or polychaete) may accumulate(More)
