| five new species of pedibothrium (tetraphyllidea: onchobothriidae) from the tawny nurse shark, nebrius ferrugineus, in the pacific ocean. | the spiral intestines of 7 tawny nurse sharks (nebrius ferrugineus; rhincodontidae) from australia and french polynesia were examined for tapeworms. these sharks hosted 5 new species of pedibothrium. the 5 species were prepared for light and scanning electron microscopy. whereas 3 of the species exhibit the bipronged hooks typical of members of pedibothrium, 1 species was found to possess tiny unipronged hooks or to lack some, or all, hooks, and all individuals of the fifth species appeared to l ... | 2004 | 15165051 |
| iucn classification zones concord with, but underestimate, the population genetic structure of the zebra shark stegostoma fasciatum in the indo-west pacific. | the indo-west pacific (iwp), from south africa in the western indian ocean to the western pacific ocean, contains some of the most biologically diverse marine habitats on earth, including the greatest biodiversity of chondrichthyan fishes. the region encompasses various densities of human habitation leading to contrasts in the levels of exploitation experienced by chondrichthyans, which are targeted for local consumption and export. the demersal chondrichthyan, the zebra shark, stegostoma fascia ... | 2009 | 19192179 |
| cross matching of blood in carcharhiniform, lamniform, and orectolobiform sharks. | the transfusion of whole blood in elasmobranchs could provide cardiovascular support following hemorrhage. since donor and recipient compatibility is not known, a technique was established to allow cross matching of red blood cells and serum in sharks. cross matching was carried out among 19 individuals from seven species: the nurse shark (ginglymostoma cirratum), sandbar shark (carcharhinus plumbeus), sandtiger shark (carcharias taurus), white-spotted bamboo shark (chiloscyllium plagiosum), bro ... | 2010 | 20945647 |
| disseminated fungal infection in two species of captive sharks. | in this report, two cases of systemic mycosis in captive sharks are characterized. these cases were progressive and ultimately culminated in terminal disease. paecilomyces lilacinus, an uncommon pathogen in human and veterinary medicine, was associated with areas of necrosis in the liver, heart, and gill in a great hammerhead shark (sphyrna mokarran). fungal growth was observed from samples of kidney, spleen, spinal fluid, and coelomic cavity swabs. dual fungal infection by exophiala pisciphila ... | 2011 | 22204064 |
| The sea louse Lepeophtheirus acutus (Caligidae, Siphonostomatoida, Copepoda) as a pathogen of aquarium-held elasmobranchs. | Lepeophtheirus acutus Heegaard, 1943 (Caligidae, Siphonostomatoida, Copepoda), was collected from or observed on four of six elasmobranch species held at Burgers' Zoo (Arnhem, The Netherlands). Circumstantial evidence suggested that a zebra shark, Stegostoma fasciatum (Hermann), from the wild carried the infection into the facility, where copepods reproduced and colonized additional hosts. Copepods typically attached on and about the eyes, in the mouth and occasionally about the cloaca and on th ... | 2011 | 21916904 |
| annually recurring parthenogenesis in a zebra shark stegostoma fasciatum. | a zebra shark, stegostoma fasciatum, held in captivity at the burj al arab aquarium, produced embryos and pups in the absence of a male. a total of 15 pups were produced from eggs laid within the aquarium over a period of four consecutive years commencing 2007. parthenogenesis was confirmed through dna analysis for three pups sampled during the first two consecutive egg cycles and is presumed to be the method of reproduction responsible thereafter. | 2011 | 22026614 |
| systemic scuticociliatosis (philasterides dicentrarchi) in sharks. | scuticociliatosis is an economically important, frequently fatal disease of marine fish in aquaculture, caused by histophagous ciliated protozoa in the subclass scuticociliatida of the phylum ciliophora. a rapidly lethal systemic scuticociliate infection is described that affected aquarium-captive zebra sharks (stegostoma fasciatum), port jackson sharks (heterodontus portusjacksoni), and a japanese horn shark (heterodontus japonicus). animals died unexpectedly or after a brief period of lethargy ... | 2014 | 23774745 |
