Isolation, identification and Analysis of Drug Resistance of Salmonella Pul-lorum

Abstract

The article provides data on the isolation and identification of the pathogen S. Pullorum from pathological material of chickens. With further study of tinctorial, cultural-morphological and biological properties of the pathogen. The susceptibility of Salmonella pullorum to broad-spectrum antibacterial drugs such as cephalosporins and carbopenems was further studied to determine the drug of choice for improving treatment and prevention of avian bacterial diseases. In order to diagnose Salmonella pullorum (S. Pullorum) diarrhea accurately and analyze its drug resistance. In this study, the pathogen of a chicken suspected of S. Pullorum was isolation, PCR amplification and drug sensitivity analysis of the pathogen from in chicken farm in Xinxiang, north China. The results showed that the bacteria strain was diagnosed as S. Pullorum base on isolation and identification, Gram staining and biochemical identification of the bacteria. Antibacterial drugs sensitivity test confirmed that the bacteria was sensitive to ceftiofur, ceftriaxone, meropenem and kanamycin, and the effect of sensitive antibiotics was obvious in clinical treatment. Altogether, the present experiment revealed a detailed measure for S. Pullorum prevention and control and that achieved good clinical results, which laid a fundamental information for farmers and veterinary workers on eradication of S. Pullorum.
