  1. The prevalence of environmental mycobacteria in drinking water supply systems in Olomouc County, north Moravia, Czech Republic, in the period 1984-1989.

    Article - En anglais

    The presence of environemental mycobacteria was studied in drinking water supply systems in Olomouc Country, Czech Republic, in order to detect the possible spread of M. kansasii from the neighbouring region in Ostrava Country.

    Drinking water samples from water supply systems of 16 localities were investigated.

    The samples of running water, and tap swabs or tap scrapings were collected twice a year, in the spring and in the autumn.

    The most common cultivated and identified species were M. gordonae (20.4%), M. flavescens (13.8%), rapidly growing mycobacteria (5.0%) and then by occasional identification of M. fortuitum, M. terrae, M. scrofulaceum.

    M. kansaii was not detected.

    The prevalence rates showed no time trend over the period 1984-1989.

    We conclude that there is no evidence at present that endemic M. kansasii, isolated repeatedly from neghbouring region, has spread to Olomouc County.

    Different environmental and nutritional constituents in soil and coal mine dust in the endemic regions seem to be the most probable limitating environmental factor of the endemic occurence of M. kansasii in its endemic locality in Ostrava and Karviná regions.
