有些药物治疗可使患者易于发生感染,而抗菌药物治疗可导致重复感染。严重的重复感染常发生于肠道,以伪膜性结肠炎(与大多数抗菌药物有关)和较少见的葡萄球菌性小肠结肠炎(常与四环素族药物有关)最为严重。抗微生物治疗引起的其他重复感染有:急性关节炎、骨髓炎、腮腺炎、肺炎、心内膜炎、败血症、地丝菌病和念珠菌病。 Some medications can make patients prone to infection, while antimicrobial medication can lead to repeated infections. Severe repeated infections often occur in the intestine, most often with pseudomembranous colitis (associated with most antibacterials) and less common staphylococcal enterocolitis (often associated with tetracycline drugs). Other repeated infections caused by antimicrobial therapy are: acute arthritis, osteomyelitis, mumps, pneumonia, endocarditis, sepsis, mycosis and candidiasis.
