Enterobacteriaceae
Enterobacteriaceae is a large family (biology), family of Gram-negative bacteria. It was first proposed by Rahn in 1936, and now includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject ...

flagella
A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates.

opportunistic infections
An opportunistic infection is an infection caused by pathogens (bacteria, fungi, parasites or viruses) that take advantage of an opportunity not normally available. These opportunities can stem from a variety of sources, such as a weakened immune ...

Etymology
The etymology of this genera is the following : ''Kluy’ver.a.'' N.L. fem. n. ''Kluyvera'', named given by Asai et al. in 1956 to honor the Dutch microbiologist A.J. Kluyver.
Transference of antibiotic resistance
In 2010, a gene blaCTX-M-15 responsible for coding CTX-M-15 extended-spectrum β-lactamase (ESBL) jumped from its chromosome to its plasmid, which was then shared among several bacteria. ESBL confers resistance to pathogenic bacterial strains. This caused the development of antibiotic resistance in almost all known pathogenic bacteria at that time.
