Article Synopsis
  • Febrile illnesses are a major health issue in sub-Saharan Africa, often leading to inadequate treatment due to limited diagnostic resources and a wide range of possible pathogens.
  • This study focused on evaluating a multiplex polymerase chain reaction (PCR) method for diagnosing febrile diseases in patients at a hospital in Central Ethiopia over two years, testing samples from 511 patients.
  • The results showed that while pathogens were detected in only 6.3% of the samples, including Plasmodium and Borrelia, the use of multiplex PCR can still enhance diagnostic capabilities and inform better clinical management in settings with limited resources.

Background: Invasive fungal infections (IFIs) contribute to significant morbidity and mortality among patients with haemato-oncological conditions, seriously ill hospitalised patients and those in intensive care (ICU). We surveyed for the World Health Organization-recommended essential diagnostic tests for IFIs in these risk groups in Africa.

Methods: The Global Action For Fungal Infections (GAFFI) evaluated the different levels of access to both diagnostics for IFIs for populations in Africa, with the aim of building a comparative dataset and a publicly available interactive map.

Antibiotics must be safe and effective for use in both human and veterinary medicine. However, information about the efficacy of different brands of antibiotics commonly used in veterinary practices is lacking in Ethiopia. In this study, we determined the efficacy of three brands of penicillin-streptomycin (Pen&strep, Penstrep, and Pro&strep) by performing antimicrobial susceptibility testing against isolated from cow milk from dairy farms in the towns of Sebata and Bishoftu, Central Ethiopia.

Objectives: is a widespread pathogen and major contributor to dyspeptic disease and gastric cancer. Although the interaction between HIV and infection is not well investigated, previous studies have suggested a decreased prevalence of and limited efficacy of eradication therapy in HIV-positive individuals. Therefore, the objectives of this study were to describe the prevalence of infection according to HIV status and analyze the efficacy of eradication therapy in Ethiopia.

Hirsch Institute of Tropical Medicine, P.O. Box 04, Asella, Ethiopia; Department of Gastroenterology, Hepatology and Infectious Diseases, University Hospital Düsseldorf, Heinrich Heine University, Moorenstr. 5, 40225 Duesseldorf, Germany.

Objectives: In resource-limited settings, intestinal Cryptosporidial or coccidian infections are common causes of chronic diarrhea but usually remain undiagnosed by routine stool investigation. Here, the addition of the Kinyoun staining technique after stool concentration was evaluated as an easy and inexpensive method for diagnosis of intestinal parasitic infection in patients with HIV.

Methods: This cross-sectional study investigated patients with HIV with diarrhea and randomly selected patients with HIV without diarrhea as controls.

Prevalence and characterization of antimicrobial resistance among gram-negative bacteria isolated from febrile hospitalized patients in central Ethiopia.

Antimicrob Resist Infect Control

January 2022

Department of Gastroenterology, Hepatology and Infectious Diseases, University Hospital Duesseldorf, Medical Faculty of Heinrich Heine University, Moorenstr. 5, 40225, Duesseldorf, Germany.

Background: Infectious diseases are among the leading causes of death in many low-income countries, such as Ethiopia. Without reliable local data concerning causative pathogens and antimicrobial resistance, empiric treatment is suboptimal. The objective of this study was to characterize gram-negative bacteria (GNB) as pathogens and their resistance pattern in hospitalized patients with infections in central Ethiopia.

Background: As a consequence of the improved availability of combined antiretroviral therapy (cART) in resource-limited countries, an emergence of HIV drug resistance (HIVDR) has been observed. We assessed the prevalence and spectrum of HIVDR in patients with failure of second-line cART at two HIV clinics in central Ethiopia.

Methods: HIV drug resistance was analysed in HIV-1-infected patients with virological failure of second-line cART using the geno2pheno application.

Ticks will diminish productivity among farm animals and transmit zoonotic diseases. We conducted a study to identify tick species infesting slaughter bulls from Adama City and to screen them for tick-borne pathogens. In 2016, 291 ticks were collected from 37 bulls in Adama, which were ready for slaughter.

Department of Gastroenterology, Hepatology and Infectious Diseases, University Hospital Düsseldorf, Heinrich-Heine-University, Düsseldorf, Germany.

Background: Despite the necessity of early recognition for an optimal outcome, sepsis often remains unrecognized. Available tools for early recognition are rarely evaluated in low- and middle-income countries. In this study, we analyzed the spectrum, treatment and outcome of sepsis at an Ethiopian tertiary hospital and evaluated recommended sepsis scores.

Background: Local data from the Asella Teaching and Referral Hospital in the town of Asella, Ethiopia reveal a high prevalence of extended-spectrum β-lactamase- (ESBL) producing Gram-negative bacteria (GNB) in clinical isolates. To investigate a possible route of transmission, we determined the proportions ESBL-producing GNB in isolates from flies caught in the hospital and in the town of Asella.

Methods: Flies were collected in August 2019 from the neonatal intensive care unit (NICU), the orthopedic ward, the hospital's waste disposal area, and from a butchery situated 1.
