In a recent study on probiotics and their effects on inflammatory bowel disease, a strain of probiotics was obtained from the gut of the Drosophilia melanogaster (a species of fly) and tested. The test was to see if the probiotic would help the disease in anyway. Many bacterial isolates were found: PTH 2, PTH 4 and PTH 7. PTH 7 was tested further because it had the best results with antimicrobial potential, intestinal juice tolerance and hydrophobic property. According to 16S rDNA study, PTH 7 turned out to be <i>Myroides pelagicus.</i> | |||

Classification
Higher order taxa
Domain: Bacteria, Phylum: Bacteroidetes, Class: Flavobacteria, Order: Flavobacteriales, Family: Flavobacterium odoratum, Genus: Myroides, Species: pelagicus
Species
Myroides pelagicus
Strain
The strain is SM1-T (=IAM 15337-T=KCTC 12661-T)
Description / Growth
Myroides pelagicus is an aerobic bacterium, meaning that it grows and thrives in oxygenated environments. The pigment of Myroides pelagicus is a yellowish orange color and grows in circular colonies on an agar. It is a gram-negative bacillus bacterium. They are described as short single rods and they are pink when stained under a microscope. Myroides pelagicus is lacks flagella, and it is non-motile because there is no bacterium moving or swarming around.
Myroides pelagicus size is 0.5-1 µm in diameter and 0.2-0.3 µm wide. Myroides pelagicus grows best when the temperature is from 10-37 °C. There is an absence of growth at 4 or 45 °C. Myroides pelagicus can handle up to 9.0% NaCl, while other species can only handle 5-6% NaCl. The range of pH for growth is 5.0-9.0. The DNA G+C content was 33.6mol%.
Location / Habitat
Myroides pelagicus was found and isolated from the seawater off the coast of Thailand for a polyphasic taxonomic study.
Metabolism
The major cellular fatty acids are C15:0iso, C17:1ω9c iso and C17:0iso 3-OH.
Current Research
In a recent study on probiotics and their effects on inflammatory bowel disease, a strain of probiotics was obtained from the gut of the Drosophilia melanogaster (a species of fly) and tested. The test was to see if the probiotic would help the disease in anyway. Many bacterial isolates were found: PTH 2, PTH 4 and PTH 7. PTH 7 was tested further because it had the best results with antimicrobial potential, intestinal juice tolerance and hydrophobic property. According to 16S rDNA study, PTH 7 turned out to be Myroides pelagicus. In conlusion, Myroides pelagicus was tested on colitic animals and was successful with reducing the proinflammatory cytokine expression. Further tests will be needed to completely prove it could be used as a drug to manage colitis.
