| prevalence, serovars, and antimicrobial susceptibility of salmonella isolated from blue land crabs (cardisoma guanhumi) in grenada, west indies. | samples of intestine and hepatopancreas from 65 blue land crabs (cardisoma guanhumi), a crustacean commonly consumed as a food item in grenada, were collected from six geographic sites in grenada and tested for salmonella by enrichment and selective culture. the individual animal prevalence of salmonella based on isolation was 17% (11 of 65), and all infected crabs were from three of the six sampled locations. isolates were identified by serotyping as salmonella enterica serovars saintpaul (n = ... | 2013 | 23834805 |
| post-exercise lactate production and metabolism in three species of aquatic and terrestrial decapod crustaceans | aquatic and terrestrial crustaceans are dependent on both aerobic and anaerobic metabolism for energy production during exercise. anaerobic energy production is marked by an accumulation of lactate in both muscle tissue and haemolymph, but the metabolic fate of lactate is not clear. lactate recycling via gluconeogenesis and the potential role of carbonic anhydrase (ca) in supplying bicarbonate for the carboxylation of pyruvate were investigated in three species of decapod crustaceans: callinecte ... | 1994 | 9317667 |
| a kinetic characterization of the gill (na+, k+)-atpase from the semi-terrestrial mangrove crab cardisoma guanhumi latreille, 1825 (decapoda, brachyura). | we provide a kinetic characterization of (na+, k+)-atpase activity in a posterior gill microsomal fraction from the semi-terrestrial mangrove crab cardisoma guanhumi. sucrose density gradient centrifugation reveals two distinct membrane fractions showing considerable (na+, k+)-atpase activity, but also containing other microsomal atpases. the (na+, k+)-atpase, notably immuno-localized to the apical region of the epithelial pillar cells, and throughout the pillar cell bodies, has an m r of around ... | 2017 | 28840273 |
| differential blockage of two types of potassium channels in the crab giant axon. | measurements were made of the kinetic and steady-state characteristics of the potassium conductance in the giant axon of the crabs carcinus maenas and cancer pagirus. the conductance increase during depolarizing voltage-clamp pulses was analyzed assuming that two separate types of potassium channels exist in these axons (m.e. quinta-ferreira, e. rojas and n. arispe, j. membrane biol. 66:171-181, 1982). it is shown here that, with small concentrations of conventional k+-channel blockers, it is po ... | 1985 | 2582131 |
