Adeleke Osho of Redeemers University, Ede, Osun, has described antibiotic-resistant bacteria, also known as superbugs, as one of the most significant threats to global public health.

Mr Osho, a professor of microbiology, said this while delivering the 16th inaugural lecture of the university on Thursday.

He said the bacteria constituted threats due to their ability to resist multiple antibiotics, rendering conventional treatments ineffective.

The lecture has the theme “The Hunt for the Superbugs.”

Mr Osho said the pathogens were responsible for severe, hard-to-treat infections, necessitating innovative approaches to address “this growing crisis.”

According to him, in 2019, a major global study estimated that antibiotic-resistant infections directly led to approximately 1.27 million deaths and contributed to around 4.95 million deaths globally.

Mr Osho said infections that were once treatable with standard antibiotics now require more intensive treatment or have limited therapeutic options, which can result in higher death rates.

“Antibiotic-resistant bacteria or superbugs refers to bacterial strains that have developed multiple resistances to antibiotics, rendering conventional treatment methods ineffective.

“These bacteria pose significant threats to global public health due to their capacity to cause severe infections that are increasingly challenging to treat.

“Treating antibiotic-resistant infections often requires longer hospital stays, more intensive care, and the use of more expensive last-resort antibiotics,” he said.

Mr Osho also said the emergence of superbugs within the healthcare facilities had profoundly affected patient care, particularly among vulnerable groups, such as the elderly, immunocompromised patients, and individuals with chronic illness.

The don, who noted that there was an urgent need to address the growing threat of superbugs, said the global health challenges had led researchers worldwide to seek alternative antimicrobials.

Mr Osho, however, said antibiotic resistance requires collective responsibility and coordinated efforts across society.

“Public awareness campaigns must emphasise the dangers of antibiotic misuse and advocate for hygiene practices that reduce infection risks.

“Educational initiatives in schools and communities can empower individuals to make informed choices about antibiotic use and infection prevention.

“Healthcare professionals play a critical role in curing resistance by adhering to prescribed guidelines, minimising unnecessary antibiotic use, and exploring alternative therapies,” he said.
