The Caribbean spiny lobster Panulirus argus supports a large and valuable fishery in the Caribbean Sea. In 2007-2008, a rare microsporidian parasite with spore characteristics typical of the Ameson genus was detected in 2 spiny lobsters from southeast Florida (FL). However, the parasite species was not confirmed by molecular analyses. To address this deficiency, reported here are structural and molecular data on single lobsters displaying comparable ‘cotton-like’ abdominal muscle containing ovoid microsporidian spores found at different locations in FL in 2014 and 2018 and in Saint Kitts and Nevis Islands in 2017. In the lobster from 2014, multiple life stages …

Four species of previously known nematodes from the family Camallanidae were found from different hosts in South Africa: Batrachocamallanus xenopodis from the frog Xenopus muelleri, Paracamallanus cyathopharynx, and Procamallanus pseudolaeviconchus from the catfish Clarias gariepinus and Spirocamallanus daleneae from the catfish Synodontis zambezensis. In the material collected from various marine fishes, several specimens of nematodes from the genus Camallanus clearly differed from all previously known species. Based on morphological differences these specimens are assigned to a new species, C. sodwanaensis. Molecular data of 18S and 28S rDNA and COI sequences are provided for the collected species …
Scaphanocephalus-Associated Dermatitis As The Basis For Black Spot Disease In Acanthuridae Of St. Kitts, West Indies, Michelle M. Dennis, Adrien Izquierdo, Anne Conan, Kelsey Johnson, Solenne Giardi, Paul Frye, Mark A. Freeman

Acanthurus spp. of St. Kitts and other Caribbean islands, including ocean surgeonfish A. bahianus, doctorfish A. chirurgus, and blue tang A. coeruleus, frequently show multifocal cutaneous pigmentation. Initial reports from the Leeward Antilles raised suspicion of a parasitic etiology. The aim of this study was to quantify the prevalence of the disease in St. Kitts’ Acanthuridae and describe its pathology and etiology. Visual surveys demonstrated consistently high adjusted mean prevalence at 3 shallow reefs in St. Kitts in 2017 (38.9%, 95% CI: 33.8−43.9) and 2018 (51.5%; 95% CI: 46.2−56.9). There were no differences in …
White Grub In Bluegill In The Sangamon River: Impact Of Sewage Effluent And Flow Regime On Infection Parameters, Miranda White
White Grub In Bluegill In The Sangamon River: Impact Of Sewage Effluent And Flow Regime On Infection Parameters, Miranda White
Masters Theses
White grub (Posthodiplostomum minimum) is a digenetic trematode that uses a piscivorous bird, a pulmonate snail, and a centrarchid fish to complete its life cycle. To assess the impact of impoundment and sewage effluent on white grub infection parameters, infections in bluegill (Lepomis macrochirus) were monitored in 3 reaches of the Sangamon River near Decatur, Illinois: Reach 1- free-flowing river upstream of Lake Decatur Dam, unimpacted by sewage effluent, Reach 2- impounded flow below Lake Decatur Dam, unimpacted by sewage effluent, and Reach 3- free-flowing river downstream of Sanitary District of Decatur, impacted by sewage effluent. Liver and kidney abundances …
