| effect of water temperature on reproductive development of benedenia seriolae (monogenea: capsalidae) from seriola lalandi in australia. | the monogenean benedenia seriolae (yamaguti, 1934) meserve, 1938 is a major pathogen of farmed yellowtail kingfish seriola lalandi in south australia. to control parasite populations in commercial farms, an understanding of the effect of water temperature on parasite development is vital. this study investigated the effect of water temperature (14, 18, 22 and 26 +/- 0.5 degrees c) on development, growth rates and age at sexual maturity of b. seriolae. five distinct developmental stages, defined ... | 2007 | 17465308 |
| molecular characterization of "candidatus parilichlamydia carangidicola," a novel chlamydia-like epitheliocystis agent in yellowtail kingfish, seriola lalandi (valenciennes), and the proposal of a new family, "candidatus parilichlamydiaceae" fam. nov. (order chlamydiales). | three cohorts of farmed yellowtail kingfish (seriola lalandi) from south australia were examined for chlamydia-like organisms associated with epitheliocystis. to characterize the bacteria, 38 gill samples were processed for histopathology, electron microscopy, and 16s rrna amplification, sequencing, and phylogenetic analysis. microscopically, the presence of membrane-enclosed cysts was observed within the gill lamellae. also observed was hyperplasia of the epithelial cells with cytoplasmic vacuo ... | 2012 | 23275507 |
