The palatability of various organs (body wall, cuvierian gland, viscera, longitudinal muscle bands and gonads) of sea cucumber Holothuria leucospilota (Brandt) was studied by feeding experiments, performed on a freshwater fish Sarotherodon mossambicus and a marine fish Theraponjarbua. The result shows that the food pellets of the body wall were less toxic and more palatable than the gonads, vis...

The sea cucumber Holothuria leucospilota has high me-dicinal value and rich nutritional edible value, and thus is a commercially important aquatic product in China. Microsatellite loci were developed and screened using a fast isolation protocol and amplified fragment length polymorphism of sequences containing repeats. In this study, 16 novel polymorphic microsatellite markers in H. leucospilot...

AChE and EROD activities were investigated in two holothurian species, Holothuria leucospilota and Holoturia atra, from a tropical coral reef. These organisms were collected from 3 back-reef stations, where temperature and salinity were homogeneous. The activity levels of both AChE and EROD varied significantly between the two species, but were in the range of values determined in other echinod...

The dermis of sea cucumbers is a catch connective tissue or mutable collagenous tissue that shows large changes in stiffness. Extensive studies on the dermis revealed that it can adopt three different states having different mechanical properties that can be reversibly converted. These are the stiff, standard and soft states. The standard state is readily produced when a dermal piece is immerse...

background: emergence of antimicrobial resistance toward a number of conventional antibiotics has triggered the search for antimicrobial agents from a variety of sources including the marine environment. objectives: the aim of this study was to evaluate the antimicrobial potential of holothuria leucospilota from qeshm and kharg islands against some selected bacteria and fungi. materials and met...

1. Stress-relaxation tests and creep tests were performed on the bodywall dermis of two sea cucumbers, Actinopyga echinites (Jager) and Holothuria leucospilota Brandt. 2. These viscoelastic connective tissues had mechanical properties which agreed well with those of a four-element mechanical model composed of two Maxwell elements connected in parallel. 3. The elastic stiffness of the dermis of ...

BACKGROUND The present study aimed to survey antileishmanial activity of methanolic Holothuria leucospilota extract against Leishmania major promastigotes in vitro. METHODS Promastigotes were cultured in RPMI 1640 and after reaching the stationary phase, the study was conducted with different concentrations of the extract. Afterwards, MTT colorimetric assay for the obtaining of 50% inhibitory...

Microplastics are found in all aquatic environments, and they can have several negative impacts on marine life. In this study, the distribution of microplastics sediment organs (gut, respiratory tree, tentacles) sea cucumber (Holothuria leucospilota) collected from Mubarak Village Cape Monze Karachi coast Pakistan were investigated. The microplastic amount different H. leucospilota was as 15.3-...
