| occurrence of enteroviruses in community swimming pools. | municipal swimming pools and wading pools were examined for the presence of human enteric viruses using a portable virus concentrator at the site to concentrate viruses from 100-gallon to 500-gallon samples. ten of 14 samples contained viruses; three of these were positive for virus in the presence of residual free chlorine. enteroviruses were isolated from two pools which exceeded the 0.4 ppm free residual chlorine standard. this study appears to be supportive of recent evidence that indicates ... | 1981 | 6267950 |
| relationships between environmental factors, bacterial indicators, and the occurrence of enteric viruses in estuarine sediments. | current standards for evaluation of the public health safety of recreational and shellfish-harvesting waters are based upon bacteriological analysis, but do not include an evaluation of the number of viruses. the objective of this study was to determine the occurrence of enteric viruses in estuarine sediments and to find a relationship, if any, between the presence of viruses in seawater or sediment or both and various biological and physicochemical characteristics of the environment. viruses we ... | 1980 | 6247974 |
| environmental factors influencing isolation of enteroviruses from polluted surface waters. | the influence of water quality upon the concentration of virus on location was assessed in field studies conducted in the houston ship channel, galveston bay, and houston waste treatment plants. clarification of polluted surface waters was accomplished with minimal loss of virus. virus from clarified sewage effluents and saline waters was then adsorbed and concentrated on textile and membrane filter surfaces. direct measurements of virus from large volumes of polluted surface waters under existi ... | 1974 | 4364463 |
| vaccine-associated paralytic poliomyelitis and bcg-osis in an immigrant child with severe combined immunodeficiency syndrome - texas, 2013. | poliovirus transmission has been eliminated in most of the world through the use of inactivated poliovirus vaccine (ipv) and live, attenuated oral poliovirus vaccine (opv). in the united states, use of opv was discontinued by the year 2000 because of the potential for vaccine-associated paralytic polio (vapp); an average of eight cases were reported each year in the united states during 1980-2000. polio eradication efforts in other parts of the world continue to rely on opv to take advantage of ... | 2014 | 25144542 |
