Abstract
A total of 83 Vibrio isolates from farmed marine shrimps (Penaeus monodon) were tested for the presence of class 1, 2 and 3 integrons, SXT constin and tetracycline resistance-encoding genes. Mutations in the quinolone resistance-determining regions (QRDRs) of the gyrA and parC genes were determined in fluoroquinolone-resistant Vibrio strains (n=17). Five isolates were found to carry class 1 integrons, of which only one contained the partial rumA gene in the variable region. All the Vibrio strains were devoid of class 2 and 3 integrons. Seven isolates harbored SXT constin. None of the Vibrio isolates were positive to the tet(K), tet(L), tet(M), tet(O) and tet(S) genes. Ten fluoroquinolone-resistant Vibrio strains carried a point mutation G-248-T in the gyrA QRDR, leading to a Ser-83-Ile substitution in GyrA, but none of these strains had mutations in the QRDR of the parC gene.Keywords
