Antibiotic susceptibility patterns of pathogenic bacteria Iiolated from the surface of tables in local restaurants in Dhaka city

Abstract

Pathogenic bacteria pose a significant threat to public health, particularly impacting vulnerable populations with compromised immune systems. Identifying the sources of pathogenic bacteria is important to prevent infections. This study aimed to isolate five pathogenic bacteria—Klebsiella pneumoniae, Escherichia coli, Salmonella spp., Shigella spp., and Vibrio cholerae from the surface of tables in local restaurants in Dhaka city. These pathogens cause illnesses such as pneumonia, bloodstream infections, urinary tract infections, salmonellosis, shigellosis, and cholera. The antibiotic susceptibility pattern of these pathogenic bacteria revealed varying resistance patterns. All isolated species of Salmonella (n=5), E. coli (n=13), Shigella (n=9) and K. pneumoniae (n=5), showed resistance to Vancomycin. Additionally, 100% isolates of Salmonella spp., E. coli and Shigella spp. exhibited resistance to Erythromycin and 100% isolates E. coli and Shigella spp. demonstrated resistance to Clindamycin. Moreover, V. cholerae (n=5) exhibited variable degree of resistance to Azithromycin (60%), Clindamycin (40%), Erythromycin (60%), Vancomycin (60%), Cefepime (40%) and Imipenem (40%). Understanding these resistance profiles is crucial for effective treatment and mitigation strategies against these pathogenic bacteria.
