Endemic occurrence of Mycobacterium kansasii in water-supply systems.

Of a total number of 1079 drinking water and colliery service water samples examined in an area of the North-Moravian Region Czechoslovakia, characterized by endemic occurrence of M. kansasii infections, 233 [21.6%] samples were found to be contaminated by mycobacteria, of these 20 [1.9%] by M. kansasii. Of additionally examined 510 water samples from the municipal water-supply network, which were collected in hospital laboratories and clinical departments as well as in the households of patients with M. kansasii infection and their possible contacts, 171 [33.5%] samples showed presence of mycobacteria, of these 18 [3.5%] were M. kansasii-positive. This mycobacterial species was isolated from the drinking water samples collected in two hospitals in the core of the endemic area, e.i. in the district of Karviná. In the district of Ostrava, where the drinking water supply, bot for colliery and households facilities, is provided from the same water-supply system, the presence of M. kansasii in the municipal water-supply network was not proved, but it was isolated from 5 samples of colliery drinking water. Further 114 samples taken from the local water treatment plant supplying the endemic area with drinking water were found to be free of M. kansasii species.

Mycobacterium kansasii infection in an endemic area of Czechoslovakia.

Over the period 1968-1979, Mycobacterium kansasii was isolated from a total of 297 persons residing in the district of Karviná, North-Moravian Region, Czechoslovakia. Repeated M. kansasii isolations were recorded in 153 patients with clinical symptomatology of chronic respiratory disorders, single isolations in another 144 persons (121 isolations from sputum and/or laryngeal swabs, 22 from urine, and one from the aspirate of a lymph node with tuberculoid granuloma). The incidence of infection with repeated M. kansasii isolation increased from 1.1 to 11.8 per 100 000 population. The ratio of these infections to the number of newly notified cases of pulmonary tuberculosis increased from 3.7 to 33.7%. The average age of patients was 46 years, 84% of all notified cases occurred by 54 years of age and morbidity was highest in the age group 45-54 years and reached 143/100 000 population. The proportion of male patients was 88% and 56% were heavy industry workers occupationally exposed to high dust concentrations.

Mass occurrence of Yersinia enterocolitica in two establishments of collective care of children.

Mass occurrence of intestinal disorders caused by Yersinia enterocolitica simultaneously in two groups of children of under-school age is reported. The question of the source of infection and the routes of transfer are discussed and the various forms pointed out which Y. e. infection may take in under-school children within the framework of an epidemic occurrence in a group of children. The fact is emphasized that the results of serological examination using the method of indirect haemagglutination may be an important guide for the orientation in the epidemiological situation and, in some cases, also in making etiological diagnosis when the proof of Y. e. by culture presents difficulties.
