Overview
The CTXφ bacteriophage (or sometimes written as CTXphi bacteriophage) is a lysogenic, filamentous, single-stranded DNA (ssDNA) phage that is responsible for turning the previously non-infectious Vibrio cholerae into a highly pathogenic microbe that causes disease in humans.[2],[3], [4]
Genetic Material
Include some current research, with at least one image.
Infection, Replication & Lysing of Host Cell
In a process known as lysogenic phage conversion, the CTXφ bacteriophage integrates, among others, its ctxAB genes into its host, Vibrio cholerae. The ctxAB genes code for a type of exotoxin, called Cholera toxin or just "CT," that causes V. cholerae to switch from being nonpathogenic to highly virulent. It is also the primary cause of the large amounts of diarrhea—cholera's main symptom.[4]
Other examples:

Italic
Subscript: H2O
Superscript: Fe3+
CT & non-CT Toxins
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.
