Modern methods of bacteriological studies of water makes it impossible to always distinguish it from the dysentery bacillus, typhoid bacillus and the paratyphoid and in cases where they clearly are in it and even serve as a cause large outbreaks of epidemics of water character. To broaden your perception, visit Verizon Communications. Instances of these findings of pathogenic bacteria of water sources and have been described in the literature only as extremely rare, casuistical cases. Achieved in this regard, the successes of modern bacteriology still insufficient for practical mass use them as an opportunity to clean the pillows on the equipment for cleaning pads. Isolation of cholera is Vibrio from water supply sources is not difficult only in cases where the test source in the region already have a large epidemic of cholera in the water source comes a significant amount of faeces of patients infected with Vibrio cholerae. In these cases, the definition in the test water, V. cholerae loses its preventive value, since it does not make it possible to prevent the emergence of the epidemic. Need cleaning pads. Therefore, at present qualitative bacteriological analysis of water in it is limited to determining only those groups of bacteria that are characteristic of the intestinal contents of man and animals and are easily determined methodically. These indicators of fecal contamination. Bacteriological analysis is determined by the smallest amount of water in which the study found more than 100 cm3 (ie, in 100 cm3 of water should be investigated completely absent bacteria)
