| rhabdosynochus spp. (monogenoidea: diplectanidae) infecting the gill lamellae of snooks, centropomus spp. (perciformes: centropomidae), in florida, and redescription of the type species, r. rhabdosynochus. | examination of the gill lamellae of 3 species of centropomus spp. (centropomidae) from 9 localities around the southern coast of florida revealed 3 species of rhabdosynochus (monogenoidea, diplectanidae). the common snook, centropomus undecimalis, was infected with rhabdosynochus rhabdosynochus (30 of 37 infected; prevalence 81%), rhabdosynochus hargisi (9 of 37; 24%), and rhabdosynochus hudsoni (20 of 37; 46%); the fat snook, centropomus parallelus, with r. rhabdosynochus (12 of 22; 55%) and r. ... | 2010 | 20496964 |
| environmental reservoirs for enterotoxigenic escherichia coli in south asian gangetic riverine system. | forecasting diarrheagenic e. coli contamination of aquatic resources to prevent outbreaks largely depends on rapid and accurate diagnostic testing in a few hours. real-time pcr is widely used for quick culture-free quantitative enumeration of pathogenic bacteria in environmental samples. in this study, real-time pcr in molecular beacon format was used for detection and culture-free quantitative enumeration of enterotoxigenic escherichia coli (etec) harboring lt1 gene in a sewage-impacted south a ... | 2010 | 20704250 |
| influence of moon phase on fish assemblages in estuarine mangrove tidal creeks. | significant differences in the composition of fish assemblages during different moon phases were detected in mangrove tidal creeks of the goiana estuary. the numbers of zabaleta anchovy anchovia clupeoides, tarpon snook centropomus pectinatus and guavina guavina guavina as well as at least 15 other species showed significant changes according to moon phase and were higher in terms of individuals (32%) and mass (34%) during the new moon. | 2011 | 21235566 |
| hydrophilic interaction liquid chromatography: esi-ms/ms of plasmalogen phospholipids from pectinatus bacterium. | liquid chromatography-electrospray tandem mass spectrometry (lc/esi-ms/ms) was used to analyze phospholipids from three species of the anaerobic beer-spoilage bacterial genus pectinatus. analysis of total lipids by hilic (hydrophilic interaction liquid chromatography) column succeeded in separating diacyl- and plasmalogen phospholipids. plasmalogens were then analyzed by means of the esi-ms/ms and more than 220 molecular species of four classes of plasmalogens (plscho (choline plasmalogen), plse ... | 2011 | 21479912 |
| endozoochorous dispersal of aquatic plants: does seed gut passage affect plant performance? | the ingestion of seeds by vertebrates can affect the germinability and/or germination rate of seeds. it is, however, unclear if an earlier germination as a result of ingestion affects later plant performance. for sago pondweed, potamogeton pectinatus, the effects of seed ingestion by ducks on both germinability and germination rate have been previously reported from laboratory experiments. we performed an experiment to determine the effects of seed ingestion by ducks on germination, seedling sur ... | 2005 | 21652448 |
| Pectinatus brassicae sp. nov., a Gram-negative anaerobic bacterium isolated from salty wastewater. | A novel Gram-negative, non-sporeforming, strictly anaerobic, heterotrophic bacterium, strain TY(T) was isolated from salty pickle wastewater. Cells were rod-shaped with comblike flagella, slightly curved and very variable in length. Optimal growth occurred at 28°C and pH 6.5. Cells were resistant to NaCl concentrate up to 50 g l(-1). Strain TY(T) produced acid from glycerin, sucrose, glucose, fructose and mannitol. The main fermentation products from glucose were acetic and propanoic acid. Test ... | 2011 | 22058316 |
| molecular analysis of the genus anoxybacillus based on sequence similarity of the genes recn, flaa, and ftsy. | genome predictions based on selected genes would be a very welcome approach for taxonomic studies. we analyzed three genes, recn, flaa, and ftsy, for determining if these genes are useful tools for systematic analyses in the genus anoxybacillus. the genes encoding a dna repair and genetic recombination protein (recn), the flagellin protein (flaa), and gtpase signal docking protein (ftsy) were sequenced for ten anoxybacillus species. the sequence comparisons revealed that recn sequence similariti ... | 2012 | 22223049 |
