INTRODUCTION
Salmonella enterica serovar Panama belongs to the D1 serogroup and is frequently associated with nontyphoidal salmonellosis in humans. This study aimed to characterize isolates collected from Northeast Brazil by phenotypic and molecular methods.
METHODS
Forty four S. Panama strains were examined for antimicrobial susceptibility, virulence genes, and pulsed field gel electrophoresis (PFGE) types.
RESULTS
All strains were susceptible to antibiotics (except for streptomycin), presented classical virulence factors, and could be clustered into four groups and 18 pulsotypes.
CONCLUSIONS
This work calls for continuous surveillance for the emergence of antibiotic resistance and new clones in a geographical area.
引言
肠炎沙门氏菌巴拿马血清型属于D1血清群，常与人类非伤寒型沙门氏菌病相关。本研究旨在通过表型和分子方法对从巴西东北部收集的分离株进行特征分析。
方法
对44株巴拿马沙门氏菌菌株进行了抗菌药物敏感性、毒力基因和脉冲场凝胶电泳（PFGE）分型检测。
结果
所有菌株对（除链霉素外的）抗生素敏感，具有典型的毒力因子，可分为四组和18种脉冲型。
结论
这项工作要求对某一地理区域内抗生素耐药性和新克隆的出现进行持续监测。
