Dr. Omolola Adenike Ajayi-Odoko’s contributions to environmental microbiology extend far beyond academia, significantly impacting public health through her extensive research on antibiotic resistance.
Her seminal work on the molecular characterization of resistant bacteria in hospital wastewater addresses a pressing global health issue, shedding light on the mechanisms and prevalence of antibiotic-resistant pathogens in medical settings. By identifying and analyzing the genetic components of these bacteria, Dr. Ajayi-Odoko’s research aids in the development of targeted treatment strategies and effective infection control measures.
Dr. Ajayi-Odoko’s academic journey began with a Bachelor’s degree in Microbiology from Obafemi Awolowo University, Ile-Ife, Nigeria, followed by a Master’s degree in Environmental Microbiology from the University of Ibadan. Her thesis on the enzymatic degradation of Nylon-6 by bacterial species showcased her early interest in applied microbiology and biodegradation.
This solid academic foundation culminated in her Ph.D. research, which has significantly impacted our understanding of antibiotic resistance in environmental contexts. Her Ph.D. thesis at Bowen University, which delved into the molecular characterization of ESBL, Carbapenemase, and AmpC β-lactamase-producing Gram-negative bacteria in wastewater from hospitals in Ibadan, Nigeria, is particularly noteworthy.
This research is crucial, as it identifies specific genetic markers and resistance mechanisms, providing a foundation for developing new antibiotics and treatments. Moreover, her findings underscore the importance of monitoring and managing hospital waste to prevent the spread of resistant bacteria into the broader environment. Dr. Ajayi-Odoko’s research has been widely recognized and published in numerous reputable journals, becoming essential references for researchers and healthcare professionals worldwide. Her work has garnered 176 citations in total, with 91 of these since 2019, reflecting the high impact and relevance of her studies in recent years.
Her h-index of 3 and i10-index of 2 further demonstrate the influence and quality of her research contributions. For instance, her publication in Environmental Science and Pollution Research on Proteus mirabilis isolated from untreated hospital wastewater in Ibadan highlighted the bacteria’s low-level resistance to fluoroquinolone and the presence of the qnrD3 gene on Col3M plasmids. Such studies are pivotal in understanding the environmental impact of hospital waste and the need for stringent infection control measures.
One of her significant publications includes the study on Proteus mirabilis isolated from untreated hospital wastewater in Ibadan, Southwestern Nigeria, which showed low-level resistance to fluoroquinolone and carried the qnrD3 gene on Col3M plasmids (This is the first report of Col3M plasmids carrying qnrD3 in environmental bacterial isolates). This research, published in Environmental Science and Pollution Research, underscores the environmental impact of hospital waste and the importance of monitoring and mitigating antibiotic resistance. In her role as a lecturer at Bowen University, Dr. Ajayi-Odoko is deeply involved in both teaching and research. She supervises undergraduate and postgraduate students, guiding them through complex research projects and fostering a culture of scientific inquiry.
Among her notable supervised projects, Omolola co-supervised O.M. Odukoya’s study on the antimicrobial activity of mushrooms against resistant isolates from houseflies, a project that is currently in progress. N. Ferguson’s thesis on the isolation and antibiotic susceptibility profile of bacteria from cow dung at Bowen University was completed under her guidance in 2024. Another student, S. Sule, graduated in 2022 after completing a study on the isolation and characterization of Gram-negative bacteria from spoiled oranges. F.M. Ibitayo’s research on the antimicrobial activity of palm kernel oil on Enterobacteriaceae isolated from hospital wastewaters was also supervised by Dr. Ajayi-Odoko and completed in 2021.
She has guided many other students, contributing significantly to their academic growth and expanding the body of knowledge in environmental microbiology. Dr. Ajayi-Odoko’s impact is further amplified through her role as an independent consultant in biological education and technical writing/editing. She has authored and co-authored over 15 research articles and served as a reviewer for the PlosONE journal, ensuring the dissemination of high-quality scientific knowledge. Her expertise has been sought after by institutions such as the University of Ibadan and Bowen University, where she has marked various microbiology modules and served as an examiner, grader, and moderator for over 20 microbiology modules.
