Professor
college of Agriculture, Engineering and Science (COAES)
Microbiology Programme

Abimbola A. Owoseni is a Professor of Microbiology at Bowen University Iwo. She has been a member of staff for 19 years rising through the ranks from an Assistant lecturer in 2004 to full professor in 2020. Her expertise lies in the fascinating world of bacterial physiology, studying antibiotic resistance in bacteria and ways to combat such through indigenous knowledge. She has also worked on bacterial enzymes in industrial products as well as in biodegradation of waste materials for animal feed. Professor Abimbola Owoseni has played an integral role in inspiring young minds to pursue careers in science. She was the best graduating student in her set and she has a passion to teach and nurture the curiosity and potential of aspiring scientists.

Research

My research experience has been on bacterial physiology majorly by studying their response to antimicrobial drugs either from synthetic or natural origin.

I moved on to work on studying antibiotic resistance using both phenotypic and genetical methods on food-borne bacteria. In addition, I studied the distribution and diversity of antibiotic resistance genes from different genera of bacteria and eventually streamlined to members of the family Enterobacteriaceae. 

This has been projected into different studies on antibiotic susceptibility and resistance including detection of antibiotic resistance and other virulence genes in the resistant bacteria. Resistance to the penicillin-based group of drugs including but not limited to ceftriaxone, amoxicillin, augmentin, and ampicillin was detected in several reports

I have worked on the identification of antibiotic-resistant genes in different bacteria including AMP-C, CTX-M, TEM, and SHV in addition to checking where these genes are located, either on the chromosome or on a plasmid. Part of my findings is that in bacterial isolates in Iwo, resistance to ampicillin is ≥95%. Worthy of note is that resistance to other antibiotics in the penicillin class, some popular cephalosporins and fluoroquinolones is on the rise (from >55% to 70% in 2020). 

In addition to the above, I have worked on studying the characterization and optimization of microbial enzymes namely amylase, protease and cellulose. For collaborative work, I have worked on biodegradation of agro-industrial wastes used for animal feed using species of Aspergillus and Penicillium as well as their enzymes. I have tested for the antimicrobial effects of synthesized chemicals from Isatin on foodborne bacteria and fungi. Studies on enzymes and bacteria isolated from fish, Clarias nigrodigitatus as well as water samples from Aiba reservoir, hand dug wells, and other water sources. 

I am working on the first grant awarded for the Bowen Bat research; studying antibiotic resistance in addition to identifying genes that confer such resistance to bacteria present in the oral and renal cavities of the straw-coloured fruit bat Eidolon helvum. 

As a member of the Bowen Mushroom research group, I have worked on using different solvent extracts of Mushrooms as bacteriostatic or bactericidal agents on multidrug-resistant bacteria isolated from food sources.
