    • 摘要: 目的:研究我院住院患者中皮肤软组织感染者(SSTIs)金黄色葡萄球(SA)感染情况及MRSA与MSSA耐药特点。方法:选取我院2018年1月1日至2020年12月31日入院时存在SSTIs且进行细菌培养及药敏试验的患者,分析SA及MRSA检出率、病种分布,以及MRSA与MSSA耐药性的差异。结果:共分析1455例患者,其中检出SA 323例,占总数比例为22.2%;MRSA阳性者72例,占SA总数的22.3%。2018-2020年MRSA检出率呈逐年升高的趋势。MRSA阳性者主要病种来源为天疱疮、大疱性类天疱疮、湿疹、银屑病、红皮病等。MRSA对阿奇霉素、青霉素、红霉素、克拉霉素、四环素等11种抗菌药物的耐药率均显著高于MSSA(均P0.05)。结论:我院SSTIs致病菌SA检出率高,MRSA在SA中占比高,且对大多数抗菌药物的耐药率显著高于MSSA。

    • 摘要: Objective:To investigate the inhibitory effect of calcium hydroxide on methicillin-resistant Staphylococcus aureus and the related inhibition mechanism.Methods:To determine the minimum inhibitory concentration of calcium hydroxide using microplate dilution method;to compare the effects of calcium hydroxide at 8MIC,MIC,1/4MIC and 0 concentrations on MRSA using growth curve method;to determine the effects of calcium hydroxide on the cell membrane of methicillin-resistant Staphylococcus aureus using calcium xanthophyll and propidium iodide fluorescence staining The effect of calcium hydroxide on the morphology of methicillin-resistant Staphylococcus aureus was observed by scanning electron microscopy;the inhibition mechanism of calcium hydroxide on MRSA was investigated by sodium dodecyl sulfate polyacrylamide gel electrophoresis of protein bands.Results:The MIC of calcium hydroxide on MRSA was 3.125 mg/mL;the fluorescence intensity showed significant changes after co-culture of calcium hydroxide with bacteria;MRSA appeared to be significantly crumpled and broken in the presence of calcium hydroxide;the SDS-PAGE experimental bands indicated that the protein inside the bacteria decreased accordingly with the increase of calcium hydroxide concentration.Conclusion:Calcium hydroxide has a significant inhibitory effect on the growth of MRSA,and its bactericidal mechanism may be related to the destruction of bacterial body structure.

    • 摘要: 以耐甲氧西林金黄色葡萄球菌(Methicillin-resistant Staphylococcus aureus,MRSA)为研究对象,对实验室研发的植物药组方MZL-1进行抗MRSA药效作用及分子机制研究。采用倍比稀释法测定MZL-1的抑菌效果,检测相对电导率、碱性磷酸酶活性变化,分析MZL-1对MRSA菌体细胞壁、细胞膜的破坏和完整性的影响,测定组方处理对MRSA细胞的促凋亡作用,并对MZL-1抗菌的可能分子作用机制进行探究。结果表明:MZL-1对MRSA的MIC(Minimal inhibit concentration)为7.5%,MZL-1处理后,MRSA菌液电导率和碱性磷酸酶活性显著增高;扫描电镜观察细胞形态差异变化大并受损,表明MZL-1破坏了MRSA细胞的完整性,导致内容物溢出,大量细胞凋亡且多出现在早期阶段;网络药理学分析发现29个化合物和23个靶基因,其中,RELA可能是核心靶基因;Gene Ontology(GO)富集分析显示靶基因主要参与细胞对小分子反应,细胞因子及转录因子等过程;Kyoto Encyclopedia of Genes and Genomes(KEGG)富集分析发现所涉及的通路主要集中在炎症反应、细胞凋亡、免疫功能及细菌和病毒感染等。研究认为组方MZL-1有望研发成为抗MRSA等耐药病原菌以及微生物感染的潜在植物源类药物。

    • 摘要: Introduction: Staphylococcus aureus is one of the most important agents involved in community and hospital-acquired infections. Due to the multi-drug resistance of strains to antibiotics, treatment to eradicate it is becoming more difficult and poses a global public health problem. Methodology: This was a cross-sectional study conducted from March to August 2020 in hospitals in the city of Douala, including all S. aureus isolates from diagnostic samples. Strain identification and antibiotic susceptibility testing were performed using the Vitek2 CompactTM (BioMerieux). Results: During the study period, 136 non-repetitive S. aureus strains were identified with a high frequency of methicillin-resistant S. aureus of 78.7%. The majority of the strains originated from the Douala General Hospital (66.9%) and was most frequently isolated from blood culture samples (55.1%). The study of biochemical characteristics showed that most of the strains identified had between 87% and 99% homology with the reference strain. The most active antibiotics were Quinupristin/Dalfopristin (94.2%), Linezolid (87.8%) and Vancomycin (84.2%). Methicillin resistance was associated with decreased susceptibility of S. aureus to other antibiotics such as Gentamycin (44.9%), Erythromycin (38.2%), Tetracycline (38.3%), Trimethoprim (21.4%), Ciprofloxacin (19.1%) and Levofloxacin (24.0%). Inducible MLSb and constitutive resistance phenotypes were identified with 26.7% and 22.8% respectively. Conclusion: The sensitivity of S. aureus strains differs from one antibiotic family to another, and remains good for molecules that are not available in our context. The high frequency of Methicillin-Resistant S. aureus shows the continuous progression of multi-resistant strains of S. aureus and their decreased sensitivity to usual antibiotics becomes more and more alarming.

    • 摘要: Methicillin-resistant Staphylococcus aureus (MRSA) is a major pathogen causing infections resulting in severe morbidity and mortality worldwide. To date, the true nature and extent of MRSA infections in the Caribbean are not well understood. This is a review of the limited studies in the Caribbean describing the prevalence, epidemiology, and molecular characteristics of MRSA in hospitalized and non-hospitalized patients. Relevant articles were searched and extracted from PubMed and Mendeley and a narrative review of the findings was constructed. An aggregate of 24 articles, from 1999 to 2020, was found from 10 of 27 countries. Majority of the studies were from Trinidad and Tobago (29%) and Jamaica (21%) while 50% were from Barbados, Dominican Republic, Martinique, Haiti, Cuba, St. Kits & Nevis, Guadeloupe, and Guyana. Approximately 75% of investigations were conducted on hospitalized patients versus 20% on outpatients. The data revealed geographical differences in the prevalence of MRSA within the Caribbean;20% - 100% of Staphylococcus aureus clinical isolates from hospitalized patients and outpatients were resistant to methicillin, macrolides, and fluoroquinolones, but susceptible to several non-beta lactam antibiotics, due to the widespread occurrence of CA-MRSA clone ST8 SCCmec IV, PVL positive. There was moderate prevalence of ST72 SCCmec V (14% - 25%) in both hospital and community settings in a few of the countries while ST30 SCCmec IV, PVL positive, was moderately prevalent (27%) only in Dominican Republic. Also, there was moderate prevalence of HA-MRSA ST5 SCCmec II (18%) in community settings in the Dominican Republic and Martinique, but high prevalence of HA-MRSA ST239 SCCmec III (60%) in hospitalized patients in Cuba and Trinidad & Tobago. The epidemiologic profile of MRSA in both hospital and community settings is changing in the Caribbean. Epidemiological studies on outpatient settings and the implementation of stringent hospital infection control measures are needed in the region.

    • 摘要: 目的了解住院病人耐甲氧西林金黄色葡萄球菌(MRSA)耐药情况及感染的主要危险因素。方法回顾性分析2019年1月~2020年12月在我院住院病人中分离的甲氧西林敏感性金黄色葡萄球菌(MSSA)和MRSA菌株的抗生素耐药性和病人感染MRSA的危险因素。结果MRSA的感染率为14.38%。MRSA菌株对青霉素G、苯唑西林、四环素、克林霉素和红霉素的耐药率高于MSSA(P值均<0.05)。使用导尿管、3个月前皮肤/伤口感染史以及住院天数增加是住院病人感染MRSA的主要危险因素(P值均<0.05)。结论MRSA的耐药性比MSSA严重,使用导尿管、3个月前皮肤/伤口感染史以及住院天数增加使得住院病人感染MRSA的风险增加。
