ABSTRACT
The
presence of pathogenic bacteria producing biofiJms in drinking water systems in
five selected villages of Umudike was determined. Four water samples (4) each
were collected from four (4) different households' drinking water systems
(storage tanks). A total of forty eight (48) different isolates were obtained
from the twenty (20) water samples. These isolates were subjected to three
different biofilm screening methods which included Congo red agar method, tube
adherence method, and tissue culture plate method. Most of the organisms which
were negative in Congo red agar method and tube adherence method gave an
optical density (OD) > 0.05nm in the tissue culture plate method and were
considered significant. The isolates that were positive in this method were
subjected to other biochemical tests for identification. Pseudomonas aeruginosa
had the highest percentage of occurrence (22.21%) of the total biofilm forming
isolates while, Bacillus spp and Acinetobacter spp had the lowest values (8.88%
each). Among the four villages examined, Umujumba and Umundiogu villages'
drinking water systems contained the highest values of the total biofilm
forming organisms (26.67% and 26.67% respectively) while Ezieke village had the
lowest value (11.11 %). The presence of these organisms in drinking water have
many implications which include a potential risk in terms of the consumer
health while in another view they may indicate the possible presence of other
bacteria, viruses or protozoan pathogens.
