Staphylococci were isolated from clinical specimens obtained from patients not known to be exposed to abnormal levels of heavy metals. The antibiotic and heavy metal resistance patterns of these strains were determined by using a disk diffusion test and computer sorting. Though not absolute, an association of resistance to mercury and tetracycline in coagulase-negative strains was found, in contrast to resistance to copper and penicillin in coagulase-producing strains. A high degree of correlation was observed between the resistance to phenyl mercury and inorganic mercury, but no correlation was obtained between resistance to methylmercury and other metals. In general, strains resistant to many agents were usually coagulase negative. A possible mechanism and implications of these associations are considered.
葡萄球菌是从临床标本中分离出来的,这些标本取自未知接触过异常水平重金属的患者。通过纸片扩散试验和计算机分类确定了这些菌株的抗生素和重金属抗性模式。尽管不是绝对的,但在凝固酶阴性菌株中发现了对汞和四环素抗性的关联,这与凝固酶产生菌株中对铜和青霉素的抗性形成对比。观察到对苯基汞和无机汞的抗性之间存在高度相关性,但对甲基汞的抗性与其他金属之间未发现相关性。一般来说,对多种药物耐药的菌株通常是凝固酶阴性。本文考虑了这些关联的可能机制及影响。
