The frequency of detection of non-polio enteroviruses in foul and fecal waste waters, water and some food products

Abstract

In the Perm Territory from 2010 to 2014 155 samples offoul andfecal waste waters, 293 samples of surface water, 827 samples of supply net water, and 57 vegetable and fruit water-washes were examined for the RNA enterovirus agent with the use of polymerase chain reaction (PCR) method. In parallel 155 wastewater samples, 20 samples of surface water, and 4 samples of supply net water were examined for non-polio enterovirus agent with the use of virological methods. In the samples of foul waste waters the RNA enterovirus agent was detected in 74.8 ± 3.4%, and nonpolio enterovirus agent - in 65.1 ± 3.8%. In the samples of surface water the RNA enterovirus agent was detected in 2.3 ± 0.8%; in the area offoul and fecal waste waters the non-polio enterovirus agent was detected in 20.0 ± 4.4% in the process of virological investigation of RNA-positive water samples. In supply net water the RNA enterovirus agent was detected in 0.8 ± 0.3 %, on the surface of vegetables, fruits, and grapes - in 10.5 ± 3.9 %.
