The effect of coating with irradiated Crab and Shrimp chitosan (CHIirr, Mv = 5.14 × 104) and un-irradiated Crab chitosan (CHIun, Mv = 2.61 × 105) on postharvest preservation of mango (Mangifera indica L.) fruit was studied. Irradiation at 100 kGy and 200 kGy of both Crab chitosan and Shrimp chitosan were used and the fruits were stored at 15°C ± 1°C and 85% relative humidity for 6 weeks. The ef...

Fish and shellfish processing employs many thousands of people globally, with shellfish processing becoming more important in recent years. Shellfish processing is associated with multiple occupational health and safety (OHS) risks. Snow crab occupational asthma (OA) is work-related asthma associated with processing snow crab. We present a gender analysis of findings from a 3-year multifaceted ...

The contamination and distribution of organochlorinated compounds were considered in three crustacean species (edible crab, Cancer pagurus; spider crab, Maja brachydactyla; velvet swimming crab, Necora puber) from five sites along the coasts of Brittany and Normandy (Western and North-Western France). PCBs (16 single congeners), pp'-DDE and HCB were measured in hepatopancreas, gonads and muscle...

Symbiont shift is rare in obligate mutualisms because both the partners are reciprocally dependent on and specialized to each other. In the obligate accommodation-transportation mutualism between walking corals and sipunculans, however, an unusual saltatory symbiont shift was discovered. In shallow waters of southern Japan, an undescribed hermit crab species was found living in corallums of sol...

Cordgrass die-offs in Cape Cod, Massachusetts, USA, salt marshes have challenged the view that the primary production of New England salt marshes is controlled by physical factors. These die-offs have increased dramatically over the last decade and are caused by the common herbivorous marsh crab Sesarma reticulatum, but other factors that control crab impacts remain unclear. We examined the inf...

The periwinkle Littorina saxatilis has repeatedly evolved both a small, fragile and globose "wave ecotype" confined to wave-swept shores and a large, robust and elongated "crab ecotype" found in nearby crab-rich but less-exposed shores. This phenotypic divergence is assumed to reflect, in some part, local adaptation to wave exposure, but this hypothesis has received incomplete experimental test...

Management of the horseshoe crab, Limulus polyphemus, is currently surrounded by controversy. The species is considered a multiple-use resource, as it plays an important role as bait in a commercial fishery, as a source of an important biomedical product, as an important food source for multiple species of migratory shorebirds, as well as in several other minor, but important, uses. Concern has...

Carbapenem-resistant Acinetobacter baumannii (CRAB) presents a serious therapeutic and infection control challenge. In this study, we investigated the epidemiological and molecular differences of CRAB and the threatening factors for contributing to increased CRAB infections at a hospital in western China. A total of 110 clinical isolates of A. baumannii, collected in a recent 2-year period, wer...

INTRODUCTION Carbapenem-resistant Acinetobacter baumannii (CRAB) infection is being increasingly observed and is associated with significant morbidity and mortality in newborns. In this study, we determined the epidemiology, risk factors, and outcomes of blood stream infection (BSI) caused by CRAB in neonates. METHODOLOGY The clinical charts of neonates who developed Acinetobacter baumannii B...

Crab shell particles were tested for its ability to remove Zn 2+ ions from aqueous solution and were evaluated in a batch reactor and in a fixed-bed column. The binding of Zn 2+ ions by crab shell was found to be affected significantly by pH, with maximum sorption capacity 71.46 mg/g observed at pH 4.5. The sorption isotherm of Zn 2+ ions on crab shell particles was modeled on the application o...
