| effect of acid ph, salts, and temperature on the infectivity and physical integrity of enteroviruses. | at 2 degrees and 30 degrees c, enteroviruses are more stable on the acid than on the alkaline side of neutrality. in the range from ph 3 to 9, temperature is so influential that the fastest inactivation rate at 2 degrees c is slower than the slowest inactivation rate at 30 degrees c. specific ions or salts also affect the rate of inactivation of enteroviruses. nacl and other chloride salts enhance the inactivation of poliovirus at ph 3. nacl is considerably less effective against poliovirus in t ... | 1976 | 13766 |

| development of quantitative methods for the detection of enteroviruses in sewage sludges during activation and following land disposal. | the development and evaluation of methods for the quantitative recovery of enteroviruses from sewage sludge are reported. activated sewage sludge solids were collected by centrifugation, and elution of the solid-associated virus was accomplished by mechanical agitation in glycine buffer at ph 11.0. eluted viruses were concentrated either onto an aluminum hydroxide floc or by association with a floc which formed de novo upon adjustment of the glycine eluate to ph 3.5. viruses which remained in th ... | 1978 | 29559 |
| partial reactivation of chlorine-treated echovirus. | after treatment of a dispersed suspension of echovirus with hocl, much of the lost plaque titer was restored if the treated virus was induced to aggregate by adjustment of the suspending medium to ph 4.5. this did not appear to be a repair of individual virions but rather a special kind of multiplicity-related increase in plaquing efficiency which occurred when the host cell received several of the damaged virions in a clump. | 1979 | 36850 |
| influence of ph, salinity, and organic matter on the adsorption of enteric viruses to estuarine sediment. | this study was designed to determine the degree of adsorption of enteric viruses to marine sediment and factors controlling this association. adsorption and elution characteristics of several enteroviruses and one rotavirus to estuarine sediments were studied under varying conditions of ph, salinity, and presence of soluble organics. greater than 99% of the added poliovirus type 1 (lsc), coxsackievirus type b3 (nancy), echovirus type 7 (wallace), and rotavirus (sa-11) adsorbed to sediment. echov ... | 1979 | 39508 |

| echo 25 focal encephalitis and subacute hemichorea. | echo virus 25 focal encephalitis was documented for the first time in a 5-year-old boy with unequivocal hemichorea. hemichorea caused by enterovirus cns disease has never been reported. echo virus antigen in cerebrospinal fluid (csf) cells was demonstrated by the indirect immunofluorescent technique and typed by a significant rise in neutralizing antibodies against echo virus 25. sequential computerized tomographic (ct) studies with digital analysis demonstrated the evolution of a focal process ... | 1979 | 571566 |
| chronic echo type 5 virus meningoencephalitis in x-linked hypogammaglobulinemia: treatment with immune plasma. | a patient with x-linked hypogammaglobulinemia developed chronic meningoencephalitis. echo virus type 5 was repeatedly cultured from cerebrospinal fluid (csf). infusions of high-titer, specific plasma resulted in clinical improvement, but failed to eradicate the virus. after more intensive plasma infusions, the virus could not be cultured from the csf. the patient died 8 months after institution of intensive therapy. the cause of death was unknown. autopsy showed persistence of perivascular and m ... | 1979 | 572004 |
| mesangiolytic glomerulonephritis in an infant with immune deficiency and echovirus infection. | an unusual glomerulonephritis characterized by diffuse mesangial cell necrosis and lysis of mesangial areas was observed in a male infant who had a combined immune deficiency and systemic echovirus type 6 infection. the occurrence of glomerular disease in a patient with combined immune deficiency indicates that the glomerular injury can be inflicted without mediation of immune mechanisms, presumably by direct cytopathic effect of echovirus 6. | 1977 | 576574 |

| [encephalomyelitis of atypical course probably caused by echovirus 7]. | the authors report a cases of encephalomyelytis caused probably by echo7 virus which was isolated from the cerebrospinal fluid after 45 days of disease. during 120 days 4 relapses of the disease were observed associated with severe general and neurological signs and cerebral coma which ultimately was the cause of death. | 1977 | 593511 |
| vesicular lesions in adults due to echovirus 11 infections. | echovirus 11 was recovered from vesicular lesions in two adults. patient 1 had a severe disseminated vesicular exanthem. patient 2 had a mild vesicular enanthem. both were clinically suspected of having herpesvirus hominis lesions. serologic studies indicate that these viruses were similar to each other and also to the "u" prime strain. | 1977 | 596902 |
| [studies of an epidemic episode of serous meningitis caused by echo-virus 30]. | the authors report an outbreak of echo 30 aseptic meningitis occurred in marche and umbria countries from november 1975 to june 1976. the clinic, epidemiologic characteristics and the serological and virological results of 28 cases are discussed. | 1977 | 597392 |

| [epidemiological studies after an outbreak of meningitis (author's transl)]. | the outbreak of meningitis during the period from the end of august to the beginning of october 1974 in kiel affected 45 children, particularly those in the age group between 4 and 9 years. an potential causative agents echo viri were identified in 15/45 cases and coxsackie b viri in 2/45 cases. the patients presented the typical meningitic symptoms (fever, headache, stiffness of the neck). in all cases the disease ran a benign course. - epidemiologically, it was possible to trace 32/45 cases ba ... | 1977 | 610256 |
| [viral meningoencephalitis: late development]. | two years ago, we performed a precocious evolutive eeg study of a specimen not selected from the virus me to echo 4 burst (cepa prima) late 1972 to early 1973 (6). some time between the appearance of the first symptoms and the 8 weeks following, alterations of cerebral electrogenesis became manifest in this study. these alterations disappeared or dimished in significance in the more tardy outlines: focalization tendency, tendency to change from "suffering" to "irritative" aspect. during this yea ... | 1977 | 616553 |

| cerebrospinal fluid lysozyme in bacterial and viral meningitis. | the concentration of lysozyme (lzm) in cerebrospinal fluid was determined in 25 patients with bacterial meningitis, in 18 patients with viral meningitis and in 25 control patients who had other fibrile illnesses. the concentration of lzm was less than 1.5 microgram/ml in all control patients, and slightly to markedly raised in 10 patients with viral meningitis and in 11 out of 13 patients with untreated bacterial meningitis. the concentration of lzm was significantly different in the viral and b ... | 1978 | 626116 |
| echovirus encephalitis and myositis in primary immunoglobulin deficiency. | two children are described with primary hypogammaglobulinaemia and encephalitis associated with echovirus infection. one also developed a condition resembling dermatomyositis which improved after he was given infusions of plasma containing antibody to the echovirus. although both died of their encephalitis, the course of the brain disease in one of them may have been prolonged by treatment with specific antibody. these cases, together with another briefly mentioned case in an adult with congenit ... | 1978 | 626516 |
