INFECTION An infection is the colonization of a hostorganism by parasitespecies. Infecting parasites seek to use the host’s resources to reproduce‚ often resulting in disease. Colloquially‚ infections are usually considered to be caused by microscopic organisms or microparasites like viruses‚ prions‚ bacteria‚ and viroids‚ though larger organisms like macroparasites and fungi can also infect. Hosts normally fight infections themselves via their immune system. Mammalian hosts react to infections

ABSTRACT The quality of pipe borne water supplied by Imo State Water Corporation has been assessed by analyzing samples of water collected from different locations for their physicochemical parameters and bacteriological quality. The observed values were compared with standard values given by the World Health Organization for potable water .The quality of the analyzed water is found fit for human consumption.
