The discovery of antibiotics many years ago marked a major milestone in the history of microbial disease treatment and control. However, the emergence and re-emergence of antibiotic-resistant strains of most pathogenic organisms, particularly in recent times, has posed a big challenge to the management of infectious diseases. Prof. Amadi and co-workers had over the years determined the prevalence rate of some pathogens in Eastern Nigeria and their susceptibility to commonly used antibiotics. The occurrence of Extended-spectrum Beta-lactamase (ESBL) enzymes among the resistant pathogens as well as their molecular characterization has been ascertained in some cases and still ongoing. Further, the effect of crude/purified medicinal plant extracts on some isolated resistant pathogens has been conducted by Prof. Amadi and Colleagues. The determination and characterization of these extracts are still on course.

In Nigeria, public health parasitic diseases have remained a big threat to the populace over the years. Efforts to determine their actual spread and distribution are vital to their prevention and control. Prof. Amadi and colleagues had previously determined the prevalence and prevention strategies of some common public health diseases such as Malaria, HIV/AIDS, Hepatitis, Syphilis etc. More works in this direction are still ongoing.

In addition, Prof. Amadi and coworkers had assessed the biogas production potentials of environmental wastes such as poultry dung, carpet grass, and Abattoir wastes, among others. Further works, using other wastes products are still ongoing.
