Carriage of Class 1 integrons and molecular characterization of gene in multidrug-resistant spp. isolates from broilers.

Aim: The present study was conducted with the following aims: (i) To screen the spp. isolates recovered from suspected cases of fowl typhoid for carriage of Class 1 integrons and analyze their association with antimicrobial resistance and (ii) to carry out molecular characterization and phylogenetic analysis of Class 1 integron-integrase () gene.

Materials And Methods: A total of 43 isolates were subjected to polymerase chain reaction (PCR) assay to determine the presence of Class1 .
