  1. aThe GC contents of host bacterial genomes available are as follows: ICEHin2866, 38.1%, ICEHin028, 38.2%; ICEHinB, 38.1%; ICEHpaT3T1, 39.6%. Genomic islands are horizontally acquired segments of DNA, with major features that include: GC content different from the rest of the genome, insertion in tRNA genes, direct repeated DNA sequences at the ends, and the presence of mobility genes. Genomic islands that are capable of integration into the chromosome of the host, excision, and self-transfer to a new host and reintegration are usually called Integrative and Conjugative Elements (ICEs).
