Peculiarities of S.Typhi isolation from the river water polluted with radionuclides at different times of the year

Abstract

Full text:Objective: to assess the effect of radionuclide pollution of river water on the isolation rate of S. Tuphi at different times of the year. Materials and methods: Since the number of typhoid fever cases reported in the Mayluusuu Valley (23 tailing pits and 16 tailing dumps are located in the area) tends to increase after the mudslides we collected river water specimens considering all these factors. Water specimens were collected from the Mayluusuu River, Shaidan-sai River, Kara-Unkur River and Ak-Buura River. Bacterial inoculation was performed in accordance with standard procedures. Concentration levels of pesticides (DDT, DDE, DDD, GCCG {alpha}, {beta}, {gamma} Aldrin and Dieldrin) were measured with a spectrograph. The present work was done in the framework of the ISTC Project KR-1516. Results and discussion: Out of the total of 2360 water specimens collected from the Shaidan-Sai River, S. Typhi was isolated from one (0.04%) water specimen. No cases of S. Typhi isolation from the water specimens collected from the Kara-Unkur River were reported for the past 10 years. Out of the total of 8969 water specimens collected from the Ak-Buura River, isolation of S. Typhi was reported in 4 (0.044%) cases. Starting from 2006 typhoid fever cases have  More>>

Out of the total of 8969 water specimens collected from the Ak-Buura River, isolation of S. Typhi was reported in 4 (0.044%) cases. Starting from 2006 typhoid fever cases have been reported in the winter and spring times among the residents of the Mayluusuu Valley. A total of 1200 patients with a presumptive diagnosis of typhoid fever were admitted to the hospitals during the period. S. Typhi was isolated from 2 out of the total of 51 (3.9%) water specimens collected from the Mayluusuu River in the winter time, 4 (2.4%) out of the total 164 - in the spring time, 3.4% and 4.5% in the summer and autumn, respectively. Concentration levels of thorium (Th) and uranium (U) were 0.025-0.045 mg/l and 0.35-15.0 mg/l. No traces of the pesticides were found in water specimens. DDE at concentration of 0.024 mg/l and GCCG {alpha} (0.06 mg/l) were found in silt specimens collected downstream the Ak-Buura River. Thus, isolation of S. Typhi from the Mayluusuu River in the winter and spring times are probably due to radionuclides of the uranium and thorium which possess an excess energy, i.e. after getting energy from these radionuclides S. Typhi may become pathogenic even in the winter time. (author)}
