A Class 4-like Chromosomal Integron Found in sp. Genomospecies Isolated from Human Feces.

Integrons are genetic elements that store, express and exchange gene cassettes. These elements are characterized by containing a gene that codes for an integrase (I), a cassette integration site (I) and a variable region holding the cassettes. Using bioinformatics and molecular biology methods, a functional integron found in sp.

Frequency and diversity of small plasmids in mesophilic Aeromonas isolates from fish, water and sediment.

Plasmids are autonomous genetic elements ubiquitously present in bacteria. In addition to containing genetic determinants responsible for their replication and stability, some plasmids may carry genes that help bacteria adapt to different environments, while others without a known function are classified as cryptic. In this work we identified and characterized plasmids from a collection of mesophilic Aeromonas spp.
