Antibiotic Resistance of Gram-Negative Bacteria from Wild Captured Loggerhead Sea Turtles

2020

Sea turtles have been proposed as health indicators of marine habitats and carriers of antibiotic-resistant bacterial strains, for their longevity and migratory lifestyle. Up to now, a few studies evaluated the antibacterial resistant flora of Mediterranean loggerhead sea turtles (Caretta caretta) and most of them were carried out on stranded or recovered animals. In this study, the isolation and the antibiotic resistance profile of 90 Gram negative bacteria from cloacal swabs of 33 Mediterranean wild captured loggerhead sea turtles are described. Among sea turtles found in their foraging sites, 23 were in good health and 10 needed recovery for different health problems (hereafter named wea…

Draft genomic sequence of Nereida ignava CECT 5292T, a marine bacterium of the family Rhodobacteraceae

2016

Nereida ignava strain 2SM4T (= CECT 5292T = DSM 16309T = CIP 108404T = CCUG 49433T) is a marine bacterium belonging to the Roseobacter group of the family Rhodobacteraceae within the class Alphaproteobacteria. The strain was isolated from sea water surrounding cultivated oysters 2–3 miles off the Mediterranean coast near Valencia (Spain) and was phylogenetically related to uncultured clones of gall symbiont bacteria of some species of Prionitis alga. Here we describe the genome sequence and annotation of this organism, the type strain of the single species of this genus. The genome comprised 2,888,349 bp, 2,872 protein-coding genes and 52 RNA genes. The annotation revealed the capacity to p…

Phylogenetic Distribution of Polysaccharide-Degrading Enzymes in Marine Bacteria

2021

Deconstruction is an essential step of conversion of polysaccharides, and polysaccharide-degrading enzymes play a key role in this process. Although there is recent progress in the identification of these enzymes, the diversity and phylogenetic distribution of these enzymes in marine microorganisms remain largely unknown, hindering our understanding of the ecological roles of marine microorganisms in the ocean carbon cycle. Here, we studied the phylogenetic distribution of nine types of polysaccharide-degrading enzymes in marine bacterial genomes. First, we manually compiled a reference sequence database containing 961 experimentally verified enzymes. With this reference database, we annota…

Identification of Vibrio spp. (other than V. vulnificus) recovered on CPC agar from marine natural samples

2000

Two hundred and eighty four presumptive but not confirmed Vibrio vulnificus isolates grown on cellobiose-polymixin B-colistin agar (CPC) at 40°C, recovered from sea water samples from Valencia, Spain, during a microbiological survey for V. vulnificus, were phenotypically identified. Most of the isolates (91%) corresponded to Vibrio species. V. harveyi (24%) and V. splendidus(19%) were the most abundant species identified, followed by V. navarrensis (13%), V. alginolyticus (8%) and V. parahaemolyticus (5%). The ability to grow on CPC agar and ferment cellobiose of several V. vulnificus strains from different origins and serovars, including reference strains, was tested. Most serovar E isolat…
