Abstract
This study studies chloramphenicol’s resistance genes of Salmonella enterica serovar Indiana isolated from chicken in China. Salmonella samples were collected from chicken hatcheries, farms and slaughter houses located in Shandong Province. Salmonella was isolated, identified and tested for drug susceptibility. The primers were designed to detect the resistance genes of chloramphenicol by PCR. The results showed that researchers isolated 23.28% strains of Salmonella enterica serovar Indiana. Resistance rates to chloramphenicol of Salmonella enterica serovar Indiana from hatcheries, farms, slaughter houses were chloramphenicol (50, 83.33, 93.30%), florfenicol (83.33, 100, 100%), thiamphenicol (63, 65, 77%), respectively. During the 80 resistant strains of chloramphenicol, 54 strains were detected catA1 genes, 74 strains were detected floR genes and the 5 strains were detected cmlA genes. These result indicated that resistance rate of Salmonella enterica serovar Indiana from three sources to chloramphenicol were different. Interestingly, researchers found that 4 isolates carried catA1, floR and cmlA genes from the farms (2), slaughter houses (2) and 49 isolates carried catA1 and floR genes from the hatchery (4), farms (19) and slaughter houses (26).
