Prof. Oluwayelu Delivers 579th Inaugural Lecture at University of Ibadan


Today, 8th May, 2025, Professor Daniel Oluwayelu of the Department of Veterinary Microbiology, Faculty of Veterinary Medicine, delivered the 579th inaugural lecture of the University of Ibadan. The lecture, titled “Foray into the World of Viruses: The Steps of the Righteous are Ordered,” was held at Trenchard Hall and had in attendance members of the university community, including the Vice-Chancellor, Professor Kayode Adebowale, Deputy Vice-Chancellors for Administration, Academics, and Research & Strategic Innovation, as well as the Dean of the Faculty of Veterinary Medicine, Professor Olufunke Ola-Davies. Also in attendance were faculty members, students, and other dignitaries, including renowned virologist Professor Oyewale Tomori.

The lecture was the 47th from the Faculty of Veterinary Medicine and the first to be delivered from the Virology Unit. In his opening remarks, Professor Oluwayelu expressed his gratitude to God for the opportunity to deliver the lecture, referencing Psalm 37:23 to reflect on his personal and academic journey. He also acknowledged the Vice-Chancellor and the Dean for the opportunity to present the lecture.

Professor Oluwayelu recounted his initial aspiration to study Medicine but was advised by his uncle to pursue Veterinary Medicine instead. He described his path through academia as one divinely ordained.

Highlighting his research contributions, Professor Oluwayelu discussed his work on the isolation and molecular characterization of the African Swine Fever Virus (ASFV) in West Africa. He also described his discovery of Chicken Anaemia Virus (CAV) in the region, identifying it as an important differential diagnosis to Infectious Bursal Disease Virus (IBDV). He was the first to achieve cell culture isolation of CAV in Nigeria, a development that led to the inclusion of CAV studies in the veterinary curriculum at the University of Ibadan, the Federal University of Agriculture, Abeokuta, and the University of Ilorin.

His doctoral research on CAV was recognised in 2006 by the National Universities Commission (NUC) as the best PhD in Veterinary Medicine in Nigeria. He also became the first to report the presence of two astroviruses in indigenous chickens in the country.


The lecture addressed the growing risk of emerging viral zoonoses, including Hepatitis E virus in pigs, Influenza A virus in dogs and poultry, and various viruses transmitted by bats. He noted that fruit bats, which often inhabit trees across the university campus, pose a potential threat and called for improved disease surveillance, control strategies, and awareness.

In his recommendations to university management, Professor Oluwayelu called for timely replacement of academic staff lost to retirement or death, improved surveillance of endemic and zoonotic diseases, and the need for public health campaigns targeting pet owners and individuals at occupational risk. He also pleaded for the provision of an incinerator to ensure the safe disposal of animal carcasses used in research.

He bemoaned the emergence of a new “highly pathogenic virus”- mediocrity, which has provided a breeding ground for nepotism and cronyism in the university community, and gradually eroding the culture of excellence by placing nepotism over merit. In his words “Let’s promote the virtue of hard-work and shun mediocrity”.

In his closing acknowledgements, Professor Oluwayelu expressed deep appreciation to his parents for instilling foundational values in him, as well as to his mentors, colleagues, staff, and family members for their support throughout his academic career.
