Introduction
Bacteroides fragilis (BF) is a Gram-negative bacterium found in the human colon. [1] Although it is relatively rare compared to other species of Bacteroides, it is the most common clinical isolate. [2] Enterotoxigenic B. fragilis (ETBF) is responsible for a large number of opportunistic infections in hospitals and contributes significantly to morbidity and mortality; however, non-enterotoxigenic B. fragilis (NTBF) has been studied as a potential probiotic. In addition to opportunistic infections, BF has been known to cause complications such as colorectal cancer and cholitis. [3] This bacterium is of interest to researchers because of its ability to evade immune responses and evolving drug resistance.
Genetics
Include some current research, with at least one image.
Section 2 Microbiome
Include some current research, with a second image.
Conclusion
Overall text length should be at least 1,000 words (before counting references), with at least 2 images. Include at least 5 references under Reference section.
