Antimicrobial resistance is an exigent public health concern owing to the emergence of novel strains of human resistant pathogens and the concurrent rise in multi-drug resistance. An influx of new antimicrobials is urgently required to improve the treatment outcomes of infectious diseases and save lives. Plant metabolites and bioactive compounds from chemical synthesis have found their efficacy to be dwindling, despite some of them being developed as drugs and used to treat human infections for several decades. Microorganisms are considered untapped reservoirs for promising biomolecules with varying structural and functional antimicrobial activity. The advent of cost-effective and convenient model organisms, state-of-the-art molecular biology, omics technology, and machine learning has enhanced the bioprospecting of novel antimicrobial drugs and the identification of new drug targets. This review summarizes antimicrobial compounds isolated from microorganisms and reports on the modern tools and strategies for exploiting promising antimicrobial drug candidates. The investigation identified a plethora of novel compounds from microbial sources with excellent antimicrobial activity against disease-causing human pathogens. Researchers could maximize the use of novel model systems and advanced biomolecular and computational tools in exploiting lead antimicrobials, consequently ameliorating antimicrobial resistance.

Amaryllidaceae is a significant source of bioactive phytochemicals with a strong propensity to develop new drugs. The genera Allium, Tulbaghia, Cyrtanthus and Crinum biosynthesize novel alkaloids and other phytochemicals with traditional and pharmacological uses. Amaryllidaceae biomolecules exhibit multiple pharmacological activities such as antioxidant, antimicrobial, and immunomodulatory effects. Traditionally, natural products from Amaryllidaceae are utilized to treat non-communicable and infectious human diseases. Galanthamine, a drug from this family, is clinically relevant in treating the neurocognitive disorder, Alzheimer’s disease, which underscores the importance of the Amaryllidaceae alkaloids. Although Amaryllidaceae provide a plethora of biologically active compounds, there is tardiness in their development into clinically pliable medicines. Other genera, including Cyrtanthus and Tulbaghia, have received little attention as potential sources of promising drug candidates. Given the reciprocal relationship of the increasing burden of human diseases and limited availability of medicinal therapies, more rapid drug discovery and development are desirable. To expedite clinically relevant drug development, we present here evidence on bioactive compounds from the genera Allium, Tulgbaghia, Cyrtanthus and Crinum and describe their traditional and pharmacological applications.

Background: Snakebite is a global environmental and occupational hazard and a significant public health threat. In rural areas, snakebite cases often go unreported and undocumented due to the lack of access to well‐structured healthcare facilities/infrastructure. In some cases, the need for antisnake venom (ASV) far outstrips supply, negatively affecting treatment outcomes. This study, therefore, assessed the epidemiological characteristics of snakebite cases, their management, and how antivenoms are utilised at the selected hospital in the Jasikan District Hospital.Methods: A 6‐year retrospective study using secondary data from antivenom return forms (pharmacy records), clinical records (patient folders), the District Health Information Management System‐2 (DHIMS‐2) database, and consulting room registers was carried out in selected hospitals in the Jasikan District, Oti, Ghana.Results: The predominant symptom of snakebite was localised pain (71.4%). The snakebite commonly occurred at home (19%) and on farms (18%). Of the 98 snakebite cases, ASV was administered to 73 (74.5%) cases. Supportive treatment applied included prophylactic antitetanus immunoglobulin (ATS) (80.6%), prophylactic antibiotics (63%), corticosteroids (80.6%), and analgesics (63%). 95% (n = 94) of complete recoveries were recorded; three were discharged against medical advice, and one was mortality. The supply and use of antivenom were erratic throughout the months of high incidence, partly due to inconsistent availability at the Regional Medical Stores. The average ASV vials and hospital stay duration were 1.23 ± 0.86 vials and 2.67 ± 1.97 days, respectively. Although the peak of snakebites occurs in April, May, and June, the demand for antivenom in April and May exceeded supply.Conclusion: The outcome of most snakebite case management was appropriate, irrespective of inadequate ASV supply in certain months. The erratic antivenom supply should be aligned with seasonal and facility‐use patterns to enhance regional snakebite management.

Background: Antimicrobial resistance (AMR) poses a critical global health challenge, particularly in resource-limited settings. A hub-and-spoke model, decentralising expertise and distributing resources to peripheral facilities, has been proposed as a strategy to enhance the antimicrobial stewardship (AMS) capacity in low- and middle-income countries. Aim: This study sought to understand healthcare professionals’ experiences of a hub-and-spoke AMS model in the Volta Region of Ghana and its influence on clinical practice, leadership, and collaborative endeavours to address AMR. Methods: A qualitative descriptive design was adopted. In-depth interviews were conducted with 11 healthcare professionals who participated in the AMS program. Thematic analysis was used to identify key themes related to the knowledge and skills that were gained, clinical and leadership practice changes, capacity building, and challenges. Results: Participants reported an increased awareness of AMR, particularly regarding the scale and clinical implications of antimicrobial misuse. The clinical practice improvements included more judicious prescribing and enhanced adherence to infection prevention and control measures. Many respondents highlighted stronger leadership skills and a commitment to capacity building through AMS committees, multidisciplinary collaboration, and cross-organisational knowledge exchange. Despite resource constraints and logistical hurdles, participants expressed optimism, citing data-driven approaches such as point prevalence surveys to track progress and inform policy. Engagement with hospital management and public outreach were viewed as essential to sustaining AMS efforts and curbing over-the-counter antibiotic misuse. Conclusions: The hub-and-spoke model caused observable improvements in AMS knowledge, clinical practice, and leadership capacity among healthcare professionals in Ghana. While challenges remain, particularly in securing sustainable resources and shifting community behaviours, these findings underscore the potential of network-based programs to catalyse systemic changes in tackling AMR. Future research should explore long-term outcomes and strategies for embedding AMS practices more deeply within healthcare systems and communities.

Unsafe disposal of unused and expired antimicrobial drugs increases their presence in the environment, thereby contributing to the emergence and spread of antimicrobial resistance. This study addressed the lack of sufficient data on unused and expired antimicrobial disposal practices among peri-urban residents in Ghana. This knowledge–attitude–practice (KAP)-based study offers context-specific insights to inform public health education and antimicrobial disposal policy interventions. A cross-sectional study was conducted among 310 residents in the Ho municipality using a well-structured questionnaire. Data was collected on the knowledge, attitudes, and practices of households on how they dispose of unused and leftover antimicrobials. Origin Pro 2022 software was used to analyze the data. Many respondents were males (n = 175, 56.5%) and aged between 18 and 30 years (n = 196, 63.2%). About 87.1% (n = 270) of the respondents agreed that improper disposal of unused antimicrobials could negatively affect the environment. Most of the respondents (71.9%, n = 223) had not received counseling on recommended antimicrobial disposal; 75.5% (n = 234) of respondents were not aware of institutions collecting unused or expired medicines; and 73.5% (n = 228) had never participated in a medicine-return program. Discarding antimicrobials into household trash bins was the most common way of disposal among respondents. The preferred sites to return unused/leftover antimicrobials were community pharmacies and hospitals. Although respondents showed some knowledge and positive attitudes toward safe antimicrobial disposal, further education is needed. Furthermore, most respondents disposed of antimicrobials in household trash, highlighting the need for take-back programs and community pharmacy-based collection. Incorporating disposal guidance into medication counseling and patient information leaflets can enhance awareness and promote appropriate practices.

Background: Analysing data on adverse drug reactions (ADRs) in health facilities is an essential step to help develop effective strategies to reduce their incidence. The objective was to analyse spontaneous ADR reports sent to the Ghanaian Food and Drugs Authority (FDA) by two reporting health facilities over 5 years.Methods: Data from duplicate spontaneous ADR reports sent to the FDA (Ghana) from 2014 to 2018 were extracted. The relationship between independent variables such as age, sex, and source of drugs and ADR outcomes was assessed with either chi‐square or a Cramer’s V test for association where appropriate.Results: Type A reactions (65.2%) were the most prevalent of the ADRs, followed by Type B (34.1%), with the majority (80%) of patients affected recovering fully. The majority of Type A reactions (54.1%) occurred in the clinic, while the majority of Type B reactions (43.5%) occurred in the hospital. The skin and central nervous system (CNS) were the most affected (70.8%) organs. A higher incidence of CNS and skin‐related ADRs was recorded in patients older than 30 (RR = 1.28 (1.07–1.53)). Also, females were more likely to experience a CNS‐related ADR. The seriousness of the ADR was found to be significantly associated with the (1) type of prescriber, (2) whether the drug was prescribed, or (3) whether the drug regimen prescribed was appropriate. Even though, in 86% of cases, the offending drug was withdrawn within the first 5 days, it exceeded 20 days in about 6% of cases. The record of allergy status in a patient’s folder and the source of the drug were significantly associated with the chance that the offending drug was withdrawn. However, recording ADRs did not influence whether the offending drug was stopped.Conclusion: Most of the ADRs experienced by patients could be avoided if the current systems are improved to prevent the rechallenge of offending drugs. Efforts to improve and update patient medication records and steps to ensure continuity of care are essential in preventing these adverse drug events.
