Background: Catheter-associated urinary tract infections (CAUTIs) due to multidrug-resistant Gram-negative bacilli (GNB) is a common concern globally. Investigating the incidence of CAUTI and associated antibiotic resistance has paramount importance from the health care associated infections perspective. This study therefore assessed the incidence of CAUTIs due to GNB and the production of extended-spectrum beta-lactamase (ESBL) and carbapenemase among inpatients in specialized hospitals of Northwest, Ethiopia.

Objective: This analysis is to present the burden and trends of morbidity and mortality due to lower respiratory infections (LRIs), their contributing risk factors, and the disparity across administrative regions and cities from 1990 to 2019.

Design: This analysis used Global Burden of Disease 2019 framework to estimate morbidity and mortality outcomes of LRI and its contributing risk factors. The Global Burden of Disease study uses all available data sources and Cause of Death Ensemble model to estimate deaths from LRI and a meta-regression disease modelling technique to estimate LRI non-fatal outcomes with 95% uncertainty intervals (UI).

Introduction: Diabetes Mellitus isa chronic metabolic disorder that required long-lasting treatment. In Ethiopian traditional medicine practices, abundant plants have been used for the treatment of diabetes mellitus for a long period. The root of is employed for the treatment of diabetes mellitus by Ethiopians.

Background: Production of Extended spectrum beta-lactamase (ESBL) and Carbapenemase is the most common strategy for drug resistance in clinical isolates of . This study was conducted to determine the magnitude of ESBL and Carbapenemase production (CPE) among clinical isolates of causing bloodstream infections (BSI) in Ethiopia.

Methods: A cross-sectional study was performed from September 2018 to January 2019 in Ethiopia.

Background: The emergence of multidrug-resistant organisms, such as extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE), and carbapenemase-producing Enterobacteriaceae (CPE) is a public health concern. Therefore, this study aimed to determine the magnitude of carbapenemase and ESBL producing bacteria isolated from patients affected by Urinary Tract Infection (UTI).

Methods: A cross-sectional study was conducted from December 2018 to March 2019 at Tikur Anbessa Specialized Hospital.

Introduction: is a well-known superbug and leading causes of wound infections. The clinical epidemiology of methicillin resistant (MRSA) and vancomycin resistant (VRSA) is not well documented in Ethiopia. The aim of this study was to determine the proportion of MRSA, VRSA and associated factors from surgical inpatients in Debre Markos Referral Hospital (DMRH), Northwest Ethiopia.

Introduction: The hospital environment contributes to the spread of Extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE), which are contributing to increased morbidity and mortality rates. The present study was carried out to detect environmental contamination, antimicrobial susceptibility testing of ESBL-PE, and to explore molecular characterization of ESBL encoding genes.

Methods: A cross-sectional study was conducted within the intensive care units (ICUs) of Tikur Anbessa Specialized Hospital from June to July 2018.

Article Synopsis
  • A study was conducted to assess bacterial contamination and antimicrobial resistance in the hospital environment, specifically focusing on surfaces in intensive care units (ICUs) and operation theaters (OTs) at Tikur Anbessa Specialized Hospital.
  • Out of 164 samples swabbed, 141 (86%) showed bacterial growth, with the highest contamination found on linens; common bacteria included Staphylococcus and coagulase-negative staphylococci.
  • High resistance levels were observed in Gram-positive bacteria against penicillin (92.8%) and in Gram-negative bacteria against ampicillin (97.5%), with 85.7% of identified isolates being methicillin-resistant (MRSA).
