Global trends in antimicrobial resistance of : a systematic review and meta-analysis of clinical isolates.

BACKGROUND

Multidrug-resistant bacteria are associated with a high number of deaths and pose a significant global concern. In recent decades, among these resistant bacteria, , a hospital-acquired pathogen, has attracted more attention.

OBJECTIVE

The present study aims to document the current state of resistance in globally by considering several variables, including geographical locations, temporal trends, and sources of infection.

METHODS

We searched studies in PubMed, Scopus, and Web of Science (30 November 2022). All statistical analyses were carried out using the statistical package R.

RESULTS

Our meta-analysis of antibiotic resistance across various clinical isolates revealed substantial heterogeneity and variability. The average resistance proportions ranged from 2% for linezolid to 62.8% for erythromycin, with significant differences observed across different time periods, countries, and World Health Organization regional offices.

CONCLUSION

Our findings confirm the high antibacterial activity of linezolid against isolates. Additionally, our investigation reveals a gradual increase and a concerning upward trend in resistance rates for nearly all agents in recent years. However, the significant reduction in resistance rates for certain antibiotics suggests that these drugs could potentially regain their effectiveness in the future.
