The human microbiome, particularly the gut microbiome, has emerged as a central determinant of health and disease. Dysbiosis, an imbalance in the microbial composition of the gut, is associated with a variety of metabolic and other diseases, highlighting the potential for microbiota-targeted treatments. Fecal microbiota transplantation has received considerable attention as a promising therapy to modulate the gut microbiome and restore microbial homeostasis. However, challenges remain, including standardization, safety, and long-term efficacy. This review summarizes current knowledge on fecal microbiota transplantation and describes the next generation therapies targeting microbiome. This review looked at the mechanistic understanding of fecal microbiota transplantation and alternative strategies, elucidating their potential role in improving dysbiosis-associated metabolic disorders, such as obesity, and type 2 diabetes and others. Additionally, this review discussed the growing application of therapies targeting the gut microbiome. Insights from clinical trials, preclinical studies, and emerging technologies provide a comprehensive overview of the evolving landscape of microbiome-based interventions. Through a critical assessment of current advances and prospects, this review aims to highlight the therapeutic potential of targeting gut microbiome and pave the way for innovative approaches in precision medicine and personalized treatments.

Background: Bacterial contamination of milk is a primary culprit for causing foodborne illnesses, presenting a significant health hazard for millions of individuals around the globe. The level and variety of microorganisms present in raw milk determine its degree of contamination and the potential health risks it poses. Methods: A cross-sectional survey was conducted from February to August. A questionnaire was used to collect data on socio-demographic characteristics and hygiene practices from milk distributors and traders. Raw milk, yoghurt, swabs from milk containers and drinking cups were collected and processed for bacterial isolation and identification, antibiotic susceptibility testing, MDR screening and confirmation, ESBL screening and confirmation. Finally, all data were pooled and analyzed using SPSS software version 25. Results: A total of 120 samples of fresh milk, yogurt and cotton swabs from milk containers and cups were collected. A total of 80 bacterial isolates were isolated from 120 samples. Among the bacteria isolated, S. aureus 17 (21.3%), E. coli 17 (21.3%), S. epidermidis 14 (17.5%), Klebsiella spp. 9 (11.3%) and Salmonella spp. 7 (8.8%) were detected most often. High rate of contamination was observed in fresh milk 23 (28.8%) and yogurt 23 (28.8%). All isolates were resistant to at least one antibiotic tested. Comparatively, high rates of resistance were observed in all isolates to the most commonly prescribed antibiotics in Ethiopia. However, lower rates of resistance have been observed for recently introduced antibiotics in Ethiopia. Of the isolates, 20 (25.0%) were resistant to eight or more antibiotics. While 16 (20.0%), 12 (15.0%), 9 (11.3%) isolates were resistant to two, three and five antibiotics, respectively. Of the bacteria isolated, 52/80 (65.0%) were MDR, 25/49 (51.0%) were screened for ESBL production, and 20/49 (40.8%) isolates were confirmed as ESBL producer. Conclusion: This study showed a high rate of bacterial isolates along with MDR and ESBL-producing strains in raw milk, yoghurt, milk container swabs and drinking cup swab samples, associated with poor hygiene and sanitation practices.

Background: Gastrointestinal colonization rate of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) is the major risk factor for infection and dissemination of resistance clones in healthcare facilities. This study aimed to investigate the magnitude of the fecal carriage of ESBL-PE and associated factors among hospitalized patients at Debre Berhan Comprehensive Specialized Hospital, North Shoa, Amhara Regional State, Ethiopia. Methods: A hospital-based cross-sectional study was conducted among 383 hospitalized patients from November 2020 to March 2021. Stool sample or rectal swab was aseptically collected and cultured on different culture media for isolation of Enterobacteriaceae. Identification was done by conventional biochemical tests. Screening of extended-spectrum beta-lactamase (ESBL) production was done by using cefotaxime and ceftazidime and confirmed by the combination disk method. Data analysis was performed by Statistical Package for Social Sciences software version 25 and a P-value ≤ 0.05 was considered as statistically significant. Results: From the total of 383 hospitalized patients, a total of 347 Enterobacteriaceae were isolated. The overall gastrointestinal colonization rate of ESBL-PE was 47.3% (164/347). The predominant ESBL-PE were E. coli 54.9% (90/164) and K. pneumoniae 33.5% (55/164). The overall multi-drug resistance rate (MDR) was 87.8% (305/347). The highest resistance was observed to ampicillin (98.3%), followed by gentamicin (80.7%), and tetracycline (73.3%), respectively. ESBL-PE were highly susceptible to meropenem (90.2%) and imipenem (89.0%). History of antibiotic use in the past 3 months (p< 0.001), admission in the neonatal intensive care unit (p=0.023), and presence of chronic disease (p< 0.001) were independently associated with fecal carriage of ESBL-PE. Conclusion: The magnitude of ESBL-PE and MDR was high in the study area. Meropenem and imipenem were active against ESBL-PE. Therefore, strict infection control measure is needed in the study area to limit the infection and dissemination of ESBL-PE.

Background: Recently, antibiotic resistance of bacteria contained in foods such as vegetables has become a public health problem. In Ethiopia, the diversity of bacterial contamination and level of antibiotic resistance in vegetables are poorly understood. Local analysis of vegetable contamination and its contribution to the spread of antibiotic resistance are therefore essential for One Health interventions. Therefore, the aim of this study was to investigate the level of bacterial contamination of commonly consumed vegetables and their antimicrobial resistance patterns. Methods: A cross-sectional research was conducted in Debre Berhan town from February to August 2022. Questionnaires were used to collect data on sociodemographic variables, hygiene practices, and market hygiene. Six carefully selected vegetables (30 each, 180 in total) were purchased at a local market. Bacterial isolation and identification, multidrug-resistant (MDR) screening and confirmation, extended-spectrum β-lactamase (ESBL) screening and confirmation, and antibiotic susceptibility tests were performed using standard operating procedure. The data were analysed statistically using SPSS software version 25. Results: The contamination rate of vegetables was 119 (66.1%). Of the 176 bacteria isolates, E. coli (26.1%; 46/176), S. aureus (18.8%; 176), S. epidermidis (10.8%; 19/176), Klebsiella spp. (9.1%; 16/179) and Acinetobacter spp. (6.8%; 12/176) were the most frequently detected isolates. Of the 180 samples tested, (66.1%; 119/180) were contaminated with at least one type of bacteria. Lettuce (22.7%; 40/176), spinach (18.6%; 33/176), and cabbage (19.2%; 32/176) were the most contaminated vegetables. Of the 176 bacteria isolates, (64.8%; 114/176) were MDR, and (18.5%; 23/124) isolates were ESBL producers. The kind of vegetables, vendor/seller finger-nail status, medium of display, market type, and not cleaned before to display were all significantly associated with bacterial contamination. Conclusion: This study found that commonly consumed vegetables are contaminated with antibiotic-resistant bacteria. Vegetables were also notable for the incidence of multidrug-resistant, extended β-lactamase-resistant, and methicillin-resistant bacterial isolates. Therefore, we urge local health authorities to develop and implement effective control strategies to reduce vegetable contamination.

Background and Aim: Transfusion‐transmissible infections (TTIs) pose a significant threat to patients requiring blood transfusion. The prevalence of TTIs among blood donors reflects the broader burden of infections within populations. Therefore, assessing the prevalence of TTIs among voluntary blood donors is crucial for informing effective prevention and control strategies in the community. Study Design and Methods: A cross‐sectional study was conducted from April 2022 to July 2022. Sociodemographic and related data were collected using a pre‐tested structured questionnaire. A venous blood sample (5 mL) was drawn from each blood donor into sterile test tubes, and serum was separated through centrifugation. The serum samples were tested using enzyme‐linked immunosorbent assays (ELISA) to detect hepatitis B Virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and syphilis. Data analysis was performed using SPSS version 25 and summarized in tables and figures. Results: A total of 538 participants were enrolled in the study, with an overall prevalence of transfusion‐transmissible infections (TTIs) at 7.4% ( n = 40). Syphilis exhibited the highest prevalence at 3% ( n = 16), followed by HBV at 2% ( n = 11). The prevalence of HCV and HIV was 1.3% ( n = 7) and 1.1% ( n = 6), respectively. Significant factors associated with HBV seroprevalence included the donation site at Debre Berhan [AOR = 24.18, 95% CI: 1.98–295.14, p = 0.01] and the presence of body tattoos [AOR = 19.1, 95% CI: 4.0–89.8, p ≤ 0.01]. Male sex was significantly associated with syphilis infections [AOR = 3.78, 95% CI: 1.23–11.61, p = 0.03]. Conclusions: This study highlighted the high prevalence of TTIs among blood donors. To prevent and control the transmission of TTIs within the population, strict donor screening protocols, improved diagnostic methods, and enhanced awareness about infection transmission should be implemented.

Background: Over the years, microbial contamination caused by foodborne bacteria has led to a significant number of food recalls, particularly for meat items that have been related to outbreaks of deadly diseases. Animals often carry Salmonella and Escherichia coli bacteria in their intestines, and these bacteria contaminate raw meat during slaughter. In addition, pathogens such as Staphylococcus aureus can contaminate meat processing equipment and utensils and spread to raw meat. Methods: A cross-sectional study was undertaken between 30 February and 15 March 2022. Sanitary conditions of abattoir and butchers and food handlers’ hygienic practices were assessed using a structured questionnaire. An equal number of meat, swabs from carcasses, knife, weighing balance and cutting board samples (24 each, 120 total) were collected from abattoir and butcher shops. The collected samples were processed for bacterial isolation, antimicrobial susceptibility testing, MDR screening and confirmation, and ESBL screening and confirmation. Finally, SPSS software version 25 was used to compile and analyze the data. Descriptive data from surveys and laboratory procedures were cross-tabulated and summarized using statistical tables and figure. Results: A total of 76 bacteria were isolated from 120 samples. Of all bacteria isolated, S. aureus 16 (21.1%). E. coli 13 (17.1%), and S. epidermidis 12 (15.8%) were the most prevalent. The rate of bacterial contamination was high in meat 18 (23.7%), carcasses 15 (19.7%) and weighing balance 15 (19.7%), respectively. Among the isolates, 18 (23.7%) were resistant for eight and more antibiotics. While, 17 (22.4%), 7(9.2%) and 4(5.3%) of the isolates were resistant for two and three, four and five, and six and seven antibiotics, respectively. Of bacteria isolated, 51/76 (67.1%) were MDR, 23/48 (47.9%) were screened for ESBL production and 13/48 (27.1%) isolates were confirmed as ESBL producer. Conclusion: Multidrug-resistant bacterial contamination was common in meat and meat contact surfaces, which was exacerbated by inadequate sanitation and hygiene practices.
