The bacteriology of the water supplies os Mandalay town

ABSTRACT

30 samples of water taken from various sources in Mandalay Town were collected in the months of June and October 1968. These were examined for the Presumptive Coliform Count, the Presumptive Enteroeoccus Count and the presence of presumptive Clostridium perfringens. Bacteria isolated from macConkey bile-salt lactose peptone water ( Cruickshank, 1965) and sodium azide medium (Hannay & Norton, 1947) primary cultures were also identified. In the June pilot survey, all 6 samples collected were unsatisfactory for drinking purposes using as criteria the Presumptive Coliform Count, the Presumptive Enterococcus Count, and the isolation of Escherichia coli and/ or Streptococcus feacalis. In the October Survey, the Yenimyaung, Moat, artesian well, shallow well, canal and Irrawaddy river samples were all unsatisfactory. Only 1 sample, viz, a rain water sample, was satisfactory. The bacterial species isolated included E. coli, Klebsiella aerogenes, Alcaligenes faecalis and S. faecalis.
