| procedure for recovery of enteroviruses from the japanese cockle tapes japonica. | the most likely shellfish to be harvested if sportfishing is reinstated in san francisco bay is the japanese cockle tapes japonica. the virus levels present in these shellfish are unknown and need to be evaluated before the shellfish beds are open. towards this end, a procedure for recovering and concentrating enteric viruses from these clams has been evaluated. effective elution of poliovirus from clam tissues was found to occur with ph 9.5 glycine-buffered saline rather than with the ph 7.5 fl ... | 1981 | 6263186 |
| open reading frame sequence of an asian enterovirus 73 strain reveals that the prototype from california is recombinant. | phylogenetic analysis within the vp1 region now enables molecular typing of enteroviruses consistent with neutralization results. three untypable isolates, 2776/82, 57/99 and 22/00, from korea, north india and bangladesh, respectively, showed within this region 98.0-99.0% amino acid identities. these were less than 77% to the previous enterovirus prototypes, but 91.5-92.5% to ca55-1988, the recently identified enterovirus 73 (ev73) prototype from california. all three strains were, however, most ... | 2002 | 12075091 |
| outbreaks of aseptic meningitis associated with echoviruses 9 and 30 and preliminary surveillance reports on enterovirus activity--united states, 2003. | aseptic or viral meningitis is the most common type of meningitis and is associated with an estimated 26,000--42,000 hospitalizations each year in the united states. enteroviruses are the most common cause of aseptic meningitis. echovirus 9 (e9) and echovirus 30 (e30) have been associated frequently with outbreaks of aseptic meningitis. during march 2003, several state public health departments noted increased reports of aseptic meningitis and, as of august 7, seven states (arizona, california, ... | 2003 | 12917581 |

| aseptic meningitis associated with echo virus type 9 infection. with special reference to variability by sex and incidence of paralytic sequelae. | the clinical and clinical laboratory findings in a group of 104 patients with aseptic meningitis associated with echo-9 infection were widely variable.a male to female case ratio of 3.7:1 was noted, and the mean age of the female group was significantly greater than that of the male group. the median of cerebrospinal fluid leukocyte counts was significantly higher in the male than in the female patients. clinical manifestations of the disease were similar to those noted in other reports. residua ... | 1965 | 14288142 |
