ISOLATION AND IDENTIFICATION OF COPPER RESISTANT BACTERIA FROM HOSPITAL WASTEWATER FROM PHC GADAU.
Abstract
ABSTRACT
Hospital wastewater contains a complex mixture of chemical and biological contaminants, including heavy metals such as copper, which exert selective pressure on microbial communities. Prolonged exposure to elevated copper levels can lead to the development of resistant bacterial strains, posing potential ecological and health concerns. This study aimed to identify and isolate copper-resistant bacteria from hospital wastewater, assess their tolerance levels, and explore their potential application in bioremediation. Wastewater samples were collected from hospital discharge points of Primary Health Care (PHC) Gadau, in Itas-Gadau LGA of Bauchi State. The waste water sample collected was subjected to standard microbiological procedures for bacterial isolation, purification, and morphological characterization. And a Copper Tolerance Tests revealed the presence of diverse bacterial species exhibiting varying degrees of resistance. The study concludes that hospital effluent provide a favorable niche for metal-resistant bacteria. Result of this study was presented using tables showing result obtained and descriptive statistics. Proper management and treatment of hospital effluents, creating awareness on safe hospital waste management and safe hospital effluents disposal policy should be created and enforced to reduce environmental and public health risks were recommended among others.
