| viral etiologies of encephalitis in thai children. | a prospective study of childhood encephalitis was performed in bangkok from 1996 through 1998. the viral agents identifiable in 26 (65%) of 40 children were dengue virus (8), japanese encephalitis (6), herpes simplex virus (4), human herpes virus type 6 (3), mumps (2), enterovirus (1), varicella-zoster virus (vzv) (1) and rabies (1). | 2001 | 11224846 |
| rapid detection of polioviruses in environmental water samples by one-step duplex rt-pcr. | this study describes the rapid detection of polioviruses in environmental waters by a simple reverse transcriptase-polymerase chain reaction (rt-pcr) using two primer pairs for differentiation of poliovirus from non-polio enteroviruses in a single reaction by a one-step method, combining rt and pcr in a single tube. the detection by agarose gel electrophoresis yielded 2 bands of 153-bp and 293-bp for poliovirus tested without the need for further hybridization. the detection sensitivity of this ... | 2000 | 11023064 |
| acute hemorrhagic conjunctivitis in southeast asian refugees arriving in the united states--isolation of enterovirus 70. | during july-september 1980, an epidemic of acute hemorrhagic conjunctivitis (ahc) occurred in several refugee camps and transit centers in southeast asia. of 2,356 refugees examined in bangkok, 200 (8.5%) had conjunctivitis, including 116 (58%) with hemorrhagic signs. because increasing numbers of refugees were arriving in the united states with conjunctivitis, a program of surveillance and control was implemented. enterovirus 70, not previously reported from patients in the western hemisphere, ... | 1982 | 6282147 |
| virological and serological studies of neurological complications of acute hemorrhagic conjunctivitis in thailand. | an extensive outbreak of acute hemorrhagic conjunctivitis (ahc) occurred from september to december 1974 in thailand. at least 29 patients with polio-like motor paralysis that complicated ahc were hospitalized in bangkok. paired or triplicate samples of serum from 16 patients were tested for neutralizing antibody to enterovirus type 70 (ev70). a significant rise in titer of antibody was found for two patients, and the other 14 had neutralizing antibody titers ranging from 1:8 to 1:512 without an ... | 1977 | 192809 |
| characterization of a virus associated with epidemic conjunctivitis in thailand. | a strain of virus, named the a-e strain, was isolated from a patient suffering from acute haemorrhagic conjunctivitis during an epidemic of the disease in bangkok in 1972. the virus had the characteristics of an enterovirus but was not neutralized by any known enterovirus antiserum. cross neutralization tests indicated that the isolate was closely related to the j670-71 virus isolated in japan. the virus produced conjunctivitis in rabbits and monkeys following conjunctival inoculation. | 1975 | 175776 |
| surveillance of enterovirus infections in bangkok. i. isolation of enterovirus from faecal specimens of healthy children. | during the period august 1970 through july 1973, about 50 faecal specimens collected each month from healthy pre-school children of lower economic status in bangkok were studied for virus isolation using primary monkey kidney cells and new born mice. from a total of 1,823 samples, 557 (30.5%) were positive: 86 (4.8%) polioviruses, 77 (4.2%) coxsackieviruses b, 223 (12.2%) echoviruses, and 127 strains (7.0%) of unidentified viruses. altogether, 45 serotypes of enteric viruses were identified. mor ... | 1975 | 167453 |
