Methicillin-resistant Staphylococcus aureus (MRSA) nasopharyngeal carriage is a major global health concern linked to severe infections and transmission. However, comprehensive evidence on the burden of MRSA carriage, antimicrobial resistance, and associated risk factors in Ethiopia remains limited. This study aimed to estimate pooled prevalence, resistance pattern, and determinants of nasopharyngeal MRSA carriage. PubMed, ScienceDirect, Scopus, Web of Science, Google Scholar, and gray literature were searched for cross-sectional studies published between January 2015 and December 2025. Two groups of reviewers screened studies based on predefined criteria. The risk of bias was assessed using the Joanna Briggs Institute tool. Pooled prevalence and resistance proportions were estimated using a random-effects model, and pooled odds ratios (ORs) were calculated using the Mantel-Haenszel method. Heterogeneity and publication bias were assessed, and a sensitivity analysis was conducted. A total of 1040 records were identified, and 20 studies (6869 participants) were included. The pooled carriage prevalence was 7.3% (95% CI, 5.0-10.8), with substantial heterogeneity (I2 = 95.5%). Resistance was highest to tetracycline (55.75%) and lowest to clindamycin (12.66%). Increased odds of carriage were associated with prior hospitalization (OR, 3.49) and antibiotic use (OR, 2.35). Inconsistent variable coding across included studies limited the inclusion of other potential risk factors. Evidence of publication bias was detected, suggesting that the pooled prevalence should be interpreted with appropriate caution. The findings indicate a considerable burden of MRSA and highlight the need for strengthened antimicrobial stewardship, improved surveillance, and targeted prevention efforts in higher-risk populations. This review was registered in PROSPERO (CRD420251047192).
INTRODUCTION: The growing challenge of antimicrobial resistance in Ethiopia and itsprogression towards XDR and PDR has become a critical public health concern. Therefore, thisreview determined the current state of emerging XDR and PDR bacteria, including pre-XDR and XDR-TB, their contributing factors, advancements, and future perspectives against drug-resistant bacteria, as well as their implications for public health and insights for future research. METHODOLOGY: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. A systematic search of all available literature was conducted using PubMed/Medline, Scopus, EMBASE, Google Scholar, Hinari, Web of Science, ScienceDirect, Cochrane Library, and African Journals Online databases.This study included original articles published in English that reported XDR and PDR bacteria, Pre-XDR-TB, and XDR-TBb without limit on the study period and publication year. Descriptive statistics were used to summarize the findings. RESULTS: Twenty-five studies published between 2010 and 2025 were included in this review. Among 5620 bacterial isolates identified,1289 were XDR (22.9%), with the prevalence ranging from 5.7% to 43.2%. A total of 440 bacterial isolates were PDR (9.1%), with its prevalence in individual studies ranged from 0.8% to 19.1%. The most common XDR bacteria identified were Klebsiella species; 26.7% (2.8%-84.6%), followed by E. coli; 26.4%(14.6%-35.7%), Acinetobacter species; 24.9%(10.1%-58.3%), and P. aeruginosa; 18.7% (2.8%-44.4%). The most frequently identified PDR bacteria were Acinetobacter species; 17.3% (7.9%-50.0%), followed by Klebsiella species; 13.7%(2.7%-25.8%), E. coli; 10.2%(2.4%-22.6%), and P. aeruginosa; 5.7%(4.3%-33.3%). Additionally, from 1419 MDR-TB and 160 TB confirmed cases, Pre-XDR-TB was 3.4% (2.4%-5.7%) and XDR-TB was 1.5%(0.6%-10.0%). These isolates were identified from different clinical specimens, which represents a significant concern in community and hospital settings. CONCLUSION: The emergence of XDR and PDR represents a major threat to Ethiopian public health, resulting in increased morbidity, mortality, prolonged hospitalizations, high healthcare costs, and challenged treatment options. Urgent national surveillance and genomic detection of resistance mechanisms are needed to better track the spread of drug-resistant bacteria, promote antimicrobial stewardship, and enhance drug and vaccine trials.
Tuberculosis remains a leading cause of death in Ethiopia but there is no effective national tuberculosis control programme. By contrast, the leprosy control programme has been very successful, with a 10-fold reduction in the number of leprosy cases requiring antibacterial treatment, though patients with nerve damage require continuing care. The paradox of rising numbers of tuberculosis cases and declining numbers of leprosy cases may be solved by joint leprosy-tuberculosis clinics. The strengths of leprosy fieldworkers in control management, case holding, and compliance can be harnessed in developing an effective tuberculosis control programme. Implementing a joint programme in Ethiopia may be beneficial not only for tuberculosis patients but also for leprosy patients, who are thus brought closer to general medical services.
