We report the complete sequence and analysis of pFR260, a novel megaplasmid of 260,595 bp from the <i>Bacillus thuringiensis</i> strain INTA Fr7-4 isolated in Argentina. It carries 7 insecticidal genes: 3 <i>cry8</i> copies previously reported, 2 <i>vip1,</i> and 2 <i>vip2</i>. Also, it carries a gene encoding a putative atypical Cry protein. These genes are arranged in a region of approximately 105 kbp in size with characteristics of a pathogenicity island with a potential coleopteran-specific insecticide profile. DNA strand composition asymmetry, as determined by GC skew analysis, and the presence of a Rep protein involved in the initiation of replication suggest a bidirectional <i>theta</i>mechanism of replication. In addition, many genes involved in conjugation and a CRISPR-Cas system were detected. The pFR260 sequence was deposited in GenBank under accession number KX258624.
