- Description: Antimicrobial resistance (AMR) is an urgent, global health problem that stems from the inappropriate use of and poor adherence to antibiotics that treat diseases in human beings. It is further exacerbated by the proliferation of antibiotics into the food chain, particularly from the overuse and misuse of antibiotics in agricultural, meat, and dairy production. The recently developed World Health Organisation (WHO) One Health (OH) approach encompasses and acknowledges the various interconnected pathways that drive AMR between the human, animal, and environmental spheres. Until recently, AMR health challenges have been viewed primarily through a biomedical lens, but this study draws on the more holistic perspective that the One Health approach offers. AMR from food sources (AMR-OH) is an underrepresented topic of research. Creating digital health communication for low-literate end-users on this topic using the One Health approach is an emerging field of research. AMR-OH has not been extensively covered in health communication campaigns and requires developing context-specific digital educational materials, such as the ones this study presents. This study draws on Social Behaviour Change Communication (SBCC) theory elements to create a suggested approach to disseminate AMR-OH information. This intervention was aimed at low-health-literate end-users to accomplish two objectives. First, create awareness and improve knowledge about AMR-OH via a video. Second, offer feasible, easily implementable behaviour change actions in the form of an infographic comprising four food safety steps (Clean, Separate, Cook, and Chill). The study was conducted in three phases. First, recruit participants and conduct a literature review to identify the effective SBCC elements of health communication intervention design. Second, conduct a needs assessment to gauge the volunteering participants’ familiarity with digital media and their current health literacy on AMR-OH. Third, conceptualise and design the two AMR-OH digital educational materials (a video and accompanying infographic). The materials were first evaluated by the researcher using the Clear Communication Index (CCI) test, and then shared with the participants via WhatsApp to be evaluated by them, using two end-user tests: the Patient Education Material Assessment Tool (PEMAT) and the Suitability Assessment of Materials (SAM) test. These two tests assessed the materials’ readability, understandability, and actionability. A post-evaluation, semi-structured interview (SSI) was then conducted with the participants. Deductive thematic analysis was conducted on the SSI data and analysed using the five design benchmarks as themes: Ease of Use of Technology, Clarity of Content, Appropriate Format, Target Audience Resonance (Appropriate for target audience), and Clear calls to Action (Actionable). The rapid onset of COVID-19 restrictions forced the project to scale down and shift entirely online. The study could be conducted due to the active and enthusiastic virtual participation of two Rhodes University Peer Educators (PEs) whose contribution was vital to developing and evaluating the materials. The needs assessment showed that the PEs were comfortable using WhatsApp, had reliable internet connection when on campus, and used this social media platform for professional and personal communication. This assessment also showed that they had prior knowledge of AMR but only from the human health perspective. The video and infographic scored high on the Clear Communication Index, 93.3% and 94.4%, respectively. The PEs’ evaluation of the materials was also high on the PEMAT and SAM assessments: video narration (100%, 80% respectively), video (100%, 99% respectively), and infographic (86%, 90% respectively). This study produced an easy-to-use, accessible and appropriate online repository of AMR-OH information in a novel format with actionable steps. The post-evaluation SSI revealed that the materials and the channel of delivery were welcomed. The PEs expressed their confidence in receiving, using, and sharing this novel presentation of evidence and solutions-based information about AMR-OH. They further highlighted that this is the first time they have received and evaluated context-specific digital multimedia about AMR-OH and that this information equipped them to adopt the food safety behaviours – namely, the four food safety steps. This study demonstrates that the theory-informed creation of engaging digital media for AMR-OH is feasible and viable. Furthermore, it affirms that engaging digital media for AMR-OH can be created to enhance the knowledge of end-users about this health issue. The scaled-down approach created a blueprint to implement a more extensive intervention in the future, informed by this intervention’s methods and tools. Lastly, this blueprint for a particular conceptualisation of an AMR-OH digital media intervention provides effective and empowering tools with which the PEs can disseminate this information to the university's support staff. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2021

- Description: Due to increased plant resistance to the existing antibiotics produced, there is a need to develop alternatives. Nonribosomal peptides (NRPs) are important plant phytopathogens synthesized by nonribosomal peptide synthetases (NRPSs). In this study, a newly sequenced Bacillus strain Bacillus atrophaeus UCMB 5137 (63Z), found to have increased phytopathogenic activity, was investigated to gain insights to the possible reason behind this activity. NRPS modules were identified using a novel script that can act on unannotated, raw DNA sequences. The Structure Based Sequence Analysis Webserver was used to identify the amino acids incorporated into the final NRP, which were compared to the NRP database. Five NRPSs were found within the strain; fengycin/plipstatin, mycosubtilin, surfactin, bacillibactin and bacitracin. Some of the modules usually present for these NRPSs were not present in the test strain and only a few modules were found. A phylogenetic study was carried out and the topologies of the trees showed that genes were not transferred horizontally. It did, however, lead to the hypothesis that different NRPS genes are under different adaptive evolutionary pressures. Only slight conformational changes between L and D-conformation of amino acids were seen between the test and neighboring strains. All of the linker and terminal regions of synthetases were found to exhibit a large amount of conservation overall. Homology modeling was performed on the test strain on selected modules, TE and A-domains of fengycin and mycosubtilin synthetases. TE-domains between the different synthetases are different and specific for the NRP they facilitate release for. The NRPS from which the A-domain originates also influences substrate specificity as well as the module in which the A-domain occurs within the NRPS. Binding pockets of A-domains of differing substrate specificity were compared. Future work will include; refinement of the models and docking studies within the A-domain binding pocket. , Microsoft� Word 2010 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Antibiotic resistance in clinical bacterial isolates remains an ongoing problem requiring continuous monitoring to effect some form of control. Comparative studies have not been previously reported for the Eastern Cape Region, South Africa and this study was undertaken to monitor resistance patterns in clinical isolates from Provincial Hospital, Port Elizabeth. Over the three year period 1989 to 1991, 9888 susceptibility results from isolates examined in the SAIMR pathology laboratory were analysed and collated using a stand-alone computer program. Resistance patterns for a range of nineteen antibiotics were collated for isolates from various sampling points within the hospital. Results were reported as resistance patterns in individually isolated species. Levels of resistance in each species were compared to those reported from South Africa and abroad, and changing patterns of resistance were noted within the three year period at the Provincial Hospital, Port Elizabeth.
