Cytophaga columnaris causes columnaris (or "cottonmouth") disease in fish such as salmon. Based on the taxonomic group this species is a part of, predict some of the activities this bacterium has during infection of fish

Also mention a related taxon that likely has some of the same functions and another taxon that does not.
What will be an ideal response?


Answer: Because C. columnaris is a member of the Cytophagales and also related to the Flavobacteriales, it is likely this organism degrades large molecular weight compounds and uses extracellular enzymes to accomplish this task. Its taxonomy also indicates it is an aerobic gram-negative bacillus-shaped bacterium such as other relatives in Cytophagales and Flavobacteriales. Unrelated taxa with dissimilar functions could range from gram-positives such as Actinobacteria and Firmicutes to gram-negatives such as Aquificae and Proteobacteria.
