Twenty-one species of sponges were recorded under the class Demospongiae and Calcareous which 19 new to Agatti reef. A total 113 Sponge endosymbiotic bacterial strains isolated from twenty-one screened for antimicrobial activity. Five sponge bacteria (SEB) namely SEB32, SEB33, SEB36, SEB43 SEB51 showed activity against virulent marine fish pathogens such as Vibrio alginolyticus, vulnificus, parahaemolyticus, Aeromonas salmonicida, Flavobacterium sp., Edwardsiella Proteus mirabilis...
The status of reefs in Palk Bay and the Gulf Mannar was studied during April-May 2016 following a bleach alert, as sea surface temperature recorded sudden increase from 30.5C to 34.0C Mannar.About 71.48% 8.9% corals 46.04% 3.78% Thoothukkudi group Islands were found bleached, showing clearly decreasing trend north south, which could be attributed corresponding pattern intensity SST study sites.Observations bleaching patterns among different life-forms showed 68% bleached massive forms.It...
To isolate antibacterial potential of sponge endosymbiotic bacteria from marine sponges at Lakshadweep archipelago. Also to identify the potent by 16s rDNA sequencing and determine activity against clinical pathogens MIC. Sponge samples was collected sub-tidal habitats Kavaratti Island identified. The were isolated selected which show in preliminary screening Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Salmonella typhi typhi), Klebsiella pneumoniea (K. pneumoniea)...
Photographic evidence of some important coral diseases (black band disease, black disease/Terpios hoshinota, white syndrome, pink line spots, invertebrate galls, skeletal growth anomalies, tissue loss), competing sponges, and coral–algal phase shifts (competitive overgrowth the seaweed Caulerpa spp. over corals competitive scleractinian interactions such as with Halimeda spp.) have been collected during field observations in a few atolls within Lakshadweep archipelago, Arabian Sea. Further,...
Our study documents the outbreak of a coral-killing sponge Terpios hoshinota in coral reefs Lakshadweep archipelago and highlights that it has further extended its territory into isolated atolls Arabian Sea maybe growing threat to existing region.
The caridean shrimp family Gnathophyllidae currently comprises five genera: Gnathophyllum Latreille, 1819; Gnathophylloides Schmitt, 1933; Pycnocaris Bruce, 1972; Levicaris 1973a and Gnathophylleptum d’Udekem d’Acoz, 2001, the last three genera being monotypic (De Grave et al., 2009). original description of chagoae 1972 was based on a pair specimens collected in Chagos Archipelago, central Indian Ocean (Bruce, 1972). Further information morphology colour pattern P. as well its association...
Symbiotic polychaete Gastrolepidia clavigera Schmarda (Phyllodocida: Polynoidae) has been documented based on the specimen collected from intertidal area of Agatti island, Lakshadweep, India. G. is found to be associated with variety holothurians such as Stichopus chloronotus, Holothuria atra and sp. The percentage occurrence individuals symbiotic host was 41.9% followed H. 38.7% chloronotus 19.3% respectively. present contribution also provides morphological diagnoses well range extension species.
Abstract Our study documents the outbreak of killer sponge Terpios hoshinota on coral reefs Lakshadweep archipelago and highlights that has further extended its territory in isolated atolls Indian subcontinent.
Endothelial dysfunction underlies many of the major complications following hematopoietic cell transplantation (HCT), including transplant-associated thrombotic microangiopathy (TA-TMA), veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS), and engraftment (ES). Emerging evidence similarly implicates endothelitis in severe COVID-19-related multi-system organ dysfunction. Given overlap these two illness states, we hypothesize that prior COVID-19 infection may increase risk for...
