Biography

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 posted a big challenge to the management of infectious diseases. Dr. 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 medicinal plant extracts on some isolated resistant pathogens has been conducted. Further determination and characterization of these extracts are still on course. Newcastle Disease (ND) remains a paramount problem to the poultry industry in Nigeria. In this regard, the occurrence rate of Newcastle disease virus has been determined in some areas of Eastern Nigeria as well as the effects of local adjuvant. Further efforts in the area of vaccine delivery techniques and identification of lentogenic/avirulent strains of the virus are our current interest. 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. Dr. Amadi and colleagues have previously determined the prevalence and prevention strategies of some common public health diseases such as malaria. The current research interest is in hand hygiene practices among different categories of people and indigenization of hand hygiene in public and private places.
