The infection is transmitted primarily via the fecal-oral route through contaminated foods or drinks. The Virus poses a significant threat to public health because of its ability to cause fulminant hepatitis which still remains a point of concern. Methods: A total of 300 samples were collected from six different hospitals within the metropolis. Fifty samples were collected from each of the hospital visited based on ethical approval from the State Ministry of Health. Blood group and Rhesus factor were tested from each sample using Blood Group antisera. The serum of each blood sample was tested for the presence of anti-HAV IgM using commercially available Micro-Point Rapid Test Kits. Results: Results analysis revealed a prevalence rate of 0.67% for HAV among the studied population. This was regarded hypoendemic. Conclusion: This study confirms previous reports about the downward trend in the global seroprevalence of HAV infections in many regions of the world. Young ages within 11-20 years (P ≤ 0.04) and Blood transfusion (P ≤ 0.04) were identified as potential risk factors for HAV contraction within the metropolis.

The research aimed at determining the antimicrobial activity of ethanol extract of Phoenix dactylifera leaves against four clinical isolates of Gram negative bacteria using Agar Disc diffusion technique. The Gram negative bacteria screened included; Escherichia coli, Morganella morganii, Proteus mirabilis and Yersinia enterocolitica. Four different concentrations tested included 20µg/disc, 40µg/disc, 80µg/disc and 160µg/disc which revealed a strong in vitro antibacterial activity against all the test organisms. Of these organisms tested, E. coli was found to be the most sensitive, followed by P. mirabilis and Y. enterocolitica producing the same zones of growth inhibition and the least sensitive organism being M. morganii. Minimum Inhibitory Concentration (MIC) was determined at 25µg/ml for all the test organisms while the Minimum Bactericidal Concentration (MBC) was probably above 100µg/ml at the highest concentration used because the organisms still managed to grow when sub-cultured on the solid media. This indicates that Phoenix dactylifera leaf extract is bacteriostatic against the test isolates used in this study.
