Abstract

The emergence and spread of extended-spectrum β-lactamase (ESBL)-producing () pose significant challenges to the treatment and control of urinary tract infections, particularly among vulnerable populations, such as the elderly living in nursing care homes. In this study, we investigated the occurrence of ESBL genes in commensal isolated from urine samples of 118 elderly individuals residing in Ghanaian nursing care homes. A total of 195 ESBL genes were detected among 41 isolated from the study participants. All the isolates harboured at least one ESBL gene, and the majority of them (70.1%) carried at least four ESBL genes. Among the ESBL genes detected, was the predominant (14.1%). In antimicrobial susceptibility testing, 65.9% of the isolates showed resistance to cefepime, a fourth-generation cephalosporin, while 56.1% showed resistance to cefotaxime, a third-generation cephalosporin. Additionally, 46.3% of the isolates were multidrug-resistant, indicating resistance to antibiotics from multiple classes. In summary, we observed relatively high rates of resistance to antibiotics as well as alarming rates of ESBL genes in the isolated pathogens. These findings emphasise the urgent need for antimicrobial stewardship and infection control programmes to mitigate the spread of multidrug-resistant pathogens in nursing care homes.

摘要

产Extended-spectrum β-lactamase (ESBL)的 的出现和传播对尿路感染的治疗和控制,尤其是对养老院等脆弱人群,如居住在养老院的老年人构成了重大挑战。在这项研究中,我们调查了在加纳养老院居住的 118 名老年人尿液样本中分离的共生 中 ESBL 基因的发生情况。在从研究参与者中分离的 41 株 中,共检测到 195 个 ESBL 基因。所有分离株均携带至少一个 ESBL 基因,其中大多数(70.1%)携带至少四个 ESBL 基因。在所检测到的 ESBL 基因中, 是最主要的(14.1%)。在抗菌药物敏感性测试中,65.9%的分离株对第四代头孢菌素头孢吡肟表现出耐药性,而 56.1%的分离株对第三代头孢菌素头孢噻肟表现出耐药性。此外,46.3%的分离株为多药耐药菌,表明对多种类别的抗生素有耐药性。总之,我们观察到分离病原体对抗生素的耐药率相对较高,以及对 ESBL 基因的惊人耐药率。这些发现强调了迫切需要进行抗菌药物管理和感染控制计划,以减轻养老院中多药耐药病原体的传播。
