Species
Bacteroides coprosuis
Description and significance
Coprosuis belongs to the genus Bacteroides. Members of the genus Bacteroides in general protect animal guts from pathogenic microorganisms and they also break down complex molecules such as polysaccharides. Bacteroides coprosuis was isolated from a manure storage pit of a swine facility;however, it is not found in an animal host.Therefore, the exact habitat remains unknown. The type strain is PC 139.
Cell structure/growing environment
Bacteroides coprosuis cells are Gram-negative, anaerobic, non-motile and non-spore-forming. They are rod-shaped organisms. Typical cells are 0·8–3·0 μm by 0·5–1·5 μm in size. The optimum temperature for Bacteroides coprosuis is 37 °C, but they can still grown within 25 to 37 °C range. It will not grow at 42 °C or higher. This bacteria is able to grow on media containing glucose, maltose and chondroitin sulfate. As a result, its fermentation products from glucose are acetic acid (8.0-15.0 mM), succinic acid (7.5-10.0 mM) and propionic acid (4.0-22.0 mM).
Antibiotic characteristics
According to a research study by Wexier, “species of the genus Bacteroides have the most antibiotic resistance mechanisms and the highest resistance rats of all anaerobic pathogens.Clinically, Bacteroides species have exhibited increasing resistance to many antibiotics, including cefoxitin, clindamycin, metronidazole, carbapenems, and fluoroquinolones ”. Bacteroides Coprosuis itself shows resistant to ampicillin (100 µg/ml), cefoxitin (20 µg/ml), erythromycin (10 µg/ml), gentamicin (200 µg/ml) and tetracycline (3 µg/ml).
Genome
The DNA G+C content of the PC139 strain is 35.0 mol% (It 36.4 mol% in Terence’s research study). The genome consists of a 2,991,798 bp long circular chromosome. Out of the 2,539 genes predicted, 2,461 were protein-coding genes, and 78 RNAs; 68 pseudogenes were identified as well. The majority of the protein-coding genes (66.4%) were assigned with a putative function while the remaining ones were annotated as hypothetical proteins (Land, 2011).
