| kudoa dianae sp. n. (myxosporea: multivalvulida), a new parasite of bullseye puffer, sphoeroides annulatus (tetraodontiformes: tetraodontidae). | a new multivalvulid myxosporean species, kudoa dianae sp. n., is described from bullseye puffer, sphoeroides annulatus (jenyns) (tetraodontiformes: tetraodontidae). plasmodia develop in extramuscular sites, in the wall of oesophagus and less frequently on mesenteries. mature spores can reach lumen of the digestive tract directly by disruption of plasmodial wall or via macrophage transport to the oesophageal epithelium. new species is characterised by morphology of spores and by the complete sequ ... | 2002 | 11993546 |
| patterns of occurrence of the platyhelminth parasites of the wild bullseye puffer (sphoeroides annulatus) off sinaloa, mexico. | this study provides basic information on the occurrence of platyhelminths in the wild bullseye puffer (sphoeroides annulatus) from sinaloa, mexico. specimens of pufferfish were collected from 2 localities: teacapan (n = 161) and mazatlan (n = 66). six species of platyhelminths were recorded: 2 monogeneans (diclidophoridae: heterobothrium ecuadori and capsalidae: neobenedenia melleni) and 4 digeneans (apocreadiidae: homalometron longisinosum, lepocreadiidae: bianium plicitum, gorgoridae: phyllodr ... | 2004 | 15165072 |
| lepeophtheirus simplex sp. n., a caligid copepod (siphonostomatoida) parasitic on "botete" (bullseye puffer, sphoeroides annulatus) in sinaloa, mexico. | a new species of caligid copepod, lepeophtheirus simplex sp. n., parasitic on bullseye puffer, sphoeroides annulatus (jenyns) in sinaloa, mexico is described. the new species is distinguished from its congeners by the possession of (1) a maxillule with simple dentiform process; (2) a sternal furca with sharply pointed, curved tines; (3) a 2-segmented exopod of leg 3 with simple, slender spine on proximal segment; (4) a 3-segmented exopod of leg 4 with a long proximal, outer spine; and (5) the te ... | 2001 | 11699661 |
| huffmanela mexicana n. sp. (nematoda: trichosomoididae) from the marine fish sphoeroides annulatus in mexico. | a new species of trichosomoidid nematodes, huffmanela mexicana n. sp., is established on the basis of its egg morphology and biological characters. the dark-shelled, embryonated eggs of this histozoic parasite occur in masses in the inner layer of the swimbladder wall of the bullseye puffer fish sphoeroides annulatus jenyns, 1843 (tetraodontidae, tetraodontiformes) off the pacific coast of mexico (sinaloa state) and are characterized mainly by their shape and size (63-69 x 30-33 microm), an aspi ... | 2000 | 11191896 |
| toxicities and distribution of tetrodotoxin in the tissues of puffer fish found in the coast of the baja california peninsula, mexico. | toxicities and tetrodotoxin distribution in tissues of five puffer fish species commonly found in the littoral of baja california peninsula, mexico (sphoeroides annulatus, s. lobatus, s. lispus, arothron meleagris and canthigaster punctatissima) were evaluated by bioassay and hplc. the toxicities estimated as tetrodotoxin-equivalents of all species were more than 0.42 microg/g in at least one of the tissues tested, and the highest was found in s. lispus liver (130 microg/g). | 2000 | 10673164 |
| seasonality of parasitic copepods on bullseye puffer, sphoeroides annulatus (pisces: tetraodontidae), from the northwestern coast of mexico. | seasonal occurrence of parasitic copepods in wild bullseye puffer, sphoeroides annulatus (pisces: tetraodontidae), was analyzed in conjunction with variation of biotic and abiotic factors. eleven samples were taken between february 2007 and february 2008 in santa maría la reforma lagoon (northwestern coast of méxico). in total, 337 fish was examined; 5 parasitic copepod species were observed, including acantholochus zairae , caligus serratus , lepeophtheirus simplex , pseudochondracanthus dicera ... | 2011 | 21506849 |
