| evaluation of insecticide impregnated baits for control of mosquito larvae in land crab burrows on french polynesian atolls. | land crab burrows are larval mosquito habitats of major significance in the pacific region. they are constituted by a sinuous tunnel leading to a chamber in contact with the water table, where mosquito larvae proliferate. controlling larvae in these sites is difficult, because the configuration of burrows prevents the use of standard techniques. an experiment was carried out in french polynesia to control aedes polynesiensis marks and culex spp. breeding in burrows of the land crab cardisoma car ... | 2002 | 12144299 |
| 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 |
| quantitation of peptide hormone in single cultured secretory neurons of the crab, cardisoma carnifex. | the content of crustacean hyperglycemic hormone (chh) in single cultured neurons of the crab cardisoma carnifex was determined by a sensitive enzyme-linked immunosorbent assay (elisa), using purified chh (1-50 pg) of the crab carcinus maenas as standard. the somata were dissociated from the group of approximately 150 peptidergic neurons that form the x-organ--sinus gland neuroendocrine system. as previously reported, the neurons show immediate regenerative outgrowth in defined culture conditions ... | 1995 | 7553771 |
| neurosecretion of crustacean hyperglycemic hormone evoked by axonal stimulation or elevation of saline k+ concentration quantified by a sensitive immunoassay method | a sandwich-type enzyme-linked immunosorbent assay (elisa) was utilized to quantify crustacean hyperglycemic hormone (as carcinus maenas equivalents) released by single x-organ­sinus gland systems of the crab cardisoma carnifex during continuous perifusion. basal rates of secretion (20­60 pg min-1) were stable for at least 4 h. electrical stimulation (600 stimuli in 5 min) of the axon tract increased secretion two- to threefold, but only if it resulted in neural activity that was propagat ... | 1994 | 9317835 |
| isolation and amino acid sequence of crustacean hyperglycemic hormone precursor-related peptides. | the crustacean hyperglycemic hormone (chh) is synthesized as part of a larger preprohormone in which the sequence of chh is n-terminally flanked by a peptide for which the name cprp (chh precursor-related peptide) is proposed. both chh and cprp are present in the sinus gland, the neurohemal organ of neurosecretory cells located in the eyestalk of decapod crustaceans. this paper describes the isolation and sequence analysis of cprps isolated from sinus glands of the crab carcinus maenas, the cray ... | 2011 | 1788131 |
| prevalence, serovars and antimicrobial susceptibility of salmonella spp. from wild and domestic green iguanas (iguana iguana) in grenada, west indies. | cloacal swabs from 62 green iguanas (iguana iguana), including 47 wild and 15 domestic ones from five parishes of grenada, were sampled during a 4-month period of january to april 2013 and examined by enrichment and selective culture for the presence of salmonella spp. fifty-five per cent of the animals were positive, and eight serovars of salmonella were isolated. the most common serovar was rubislaw (58.8%), a serovar found recently in many cane toads in grenada, followed by oranienburg (14.7% ... | 2014 | 24325463 |
| 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 |
