摘要

摘要: 目的调查广东省部分人群（动物从业人员和一般人群）的多重耐药金葡菌（multidrug-resistant S. aureus，MDRSA）携带情况，并分析菌株的耐药性。方法对研究对象进行问卷调查和鼻拭子采样，对金葡菌进行药敏试验，分析方法采用χ²检验。结果动物从业人员中金葡菌、MDRSA、甲氧西林耐药金葡菌（methicillin-resistant S. aureus，MRSA）的携带率均高于对照人群（分别为13.3% vs 9.3%；9.5% vs 3.4%；7.0% vs 1.4%；均有P<0.01）。金葡菌对青霉素、克林霉素、四环素和红霉素的耐药率较高，MDRSA主要耐药模式是同时对克林霉素、红霉素、四环素耐药。除了青霉素外，动物从业人员金葡菌对各类抗生素的耐药率均高于对照人群；MRSA菌株对各类抗生素的耐药率均高于甲氧西林敏感金葡菌。结论本研究提示职业性动物接触可能导致从业人员感染耐药细菌。

Abstract: Objective To investigate the carriage rate and antibiotic resistance of multidrug-resistant S. aureus among animal-related workers and general population in Guangdong Province. Methods We surveyed the study population by face-to-face questionnaire and nasal swab sampling. All S. aureus isolates were tested for antibiotic susceptibility test, and the data were analyzed by chi-squared test. Results The carriage rates of S. aureus, multidrug-resistant S. aureus and methicillin-resistant S. aureus (MRSA) were higher in animal-related workers than in controls (13.3% vs 9.3%; 9.5% vs 3.4%; 7.0% vs 1.4%; all P<0.01). The rates of S. aureus isolates showed high levels of resistance to penicillin, clindamycin, tetracycline and erythromycin, and the dominant multidrug resistance pattern of multidrug-resistant S. aureus isolates were mainly resistant to clindamycin, erythromycin and tetracycline. S. aureus strains isolated from animal-related workers showed higher levels of resistances to antibiotics, except for penicillin, than those from general population. The antibiotic-resistant rate was higher in MRSA isolates than in methicillin-sensitive S. aureus isolates. Conclusions This study suggests that occupational animal contact may lead to the infection of drug resistant bacteria.
