This study aimed to conduct first robust meta-meta-analysis on mecC and mecA-positive MRSA strains, determining their overall prevalence and temporal trends. It encompassed 14 meta-analyses, involving 322,269 samples from 553 index studies. MRSA strains exhibited mecA / mecC positivity ranging from 0.90 % to 69.98 %. Varied AMSTAR and QUOROM scores were observed. mecC-positive MRSA prevalence was 2.41 % (95 % CI: 0.72-7.78 %). Human mecA-positive MRSA had 21.77 % prevalence (95 % CI: 9.08-43.67 %), animal samples had 7.08 % prevalence (95 % CI: 3.93-12.42 %), and worldwide prevalence was 14.58 % (95 % CI: 6.61-29.14 %). Temporal trends reveal fluctuations, mecA prevalence spiked to 52.68 % in 2012 and decreased to 7.11 % in 2022. For mecC gene, the year 2015 marked a low incidence of 0.41 % (95 % CI: 0.05-3.54 %). Overall, mecA gene carriage surpassed mecC in MRSA strains, especially in humans.
本研究旨在对mecC和mecA阳性的耐甲氧西林金黄色葡萄球菌（MRSA）菌株进行首次稳健的元元分析，确定其总体流行率和时间趋势。该研究涵盖了14项元分析，涉及来自553项索引研究的322,269个样本。MRSA菌株的mecA / mecC阳性率在0.90%至69.98%之间。观察到不同的AMSTAR和QUOROM评分。mecC阳性MRSA的流行率为2.41%（95%CI：0.72 - 7.78%）。人类mecA阳性MRSA的流行率为21.77%（95%CI：9.08 - 43.67%），动物样本的流行率为7.08%（95%CI：3.93 - 12.42%），全球流行率为14.58%（95%CI：6.61 - 29.14%）。时间趋势显示存在波动，mecA流行率在2012年飙升至52.68%，在2022年降至7.11%。对于mecC基因，2015年发病率较低，为0.41%（95%CI：0.05 - 3.54%）。总体而言，MRSA菌株中mecA基因携带率超过mecC，尤其是在人类中。
