| [acute hemorrhagic conjunctivitis caused by a variant of coxsackievirus a24, in belém, pará, brazil, 1987]. | an epidemic of acute haemorrhagic conjunctivitis in belém, pará, brazil, was investigated. from 83 patients, 73 samples of virus was isolated in cultures of hep-2 cells from conjunctival swab and throat swab. the virus isolates were identified in centers for disease control, atlanta, georgia, usa, as an antigenic variant of coxsackievirus a24. neutralization test was done on 56 paired serum samples, using entero virus type 70 (ev70) and virus isolates. serological conversions for virus isolates ... | 1989 | 2559469 |
| enteroviruses as a possible cause of myocarditis, pericarditis and dilated cardiomyopathy in belém, brazil. | we attempted to assess the role of enteroviruses in the etiology of myocarditis (mc), pericarditis (pc) and dilated cardiomyopathy (dcm) among 15 in-patients at a public hospital in belém, brazil, from november 1992 to december 1993. we obtained stool specimens and throat swabs from each patient (particularly acute cases) and, when possible, acute and convalescent serum samples for both isolation and serological procedures. mc, pc and dcm occurred in 10, 2 and 3 patients, respectively, mostly in ... | 1995 | 8555988 |
| detection of enteroviruses in cases of neurological disorders in the state of pará, brazil. | eighty-one cerebrospinal fluid (csf) samples mainly from cases of aseptic meningitis and motor deficiency syndrome were sent to the virology section of evandro chagas institute, belém pará, in the period of january 1995 to january 1996 in order to isolate viruses. all samples were inoculated onto hep-2 cell culture and newborn mice, with negative results. the probability of isolating viruses by these methods is reduced because of the low concentration of viral particles in these specimens. in or ... | 2001 | 11781601 |
| neutralizing antibodies to enterovirus 71 in belém, brazil. | non-polio enteroviruses (coxsackievirus a, coxsackievirus b, echovirus and ev 68-72) which belong to the enterovirus (ev) genus, picornaviridae family, may be responsible for acute flaccid paralysis, aseptic meningitis, myocarditis, hepatitis, pleurodinia, neonatal sepsis, hand, foot and mouth disease (hfmd) even though 50-80% of infections are asymptomatic. ev 71 has been responsible for outbreaks and epidemics of hfmd and acute neurologic disease justifying its study in our country. the aim of ... | 2002 | 11992146 |
| first isolation of enterovirus 71 (ev-71) from northern brazil. | enterovirus 71 (ev-71) has been associated to cases of neurological disease in many countries including brazil. this virus has now been reported from three of the five brazilian regions. our study relates the findings concerning to the first isolate of this virus in northern region of brazil. a 15-month old female patient, from the rural zone of the municipality of santana do araguaia in southern pará state was admitted at the hospital with acute, flaccid, asymmetric and ascending motor deficien ... | 2003 | 14533990 |
| molecular and seroepidemiologic studies of enterovirus 71 infection in the state of para, brazil. | in many countries, the enterovirus 71 (ev-71) picornaviridae family is associated to hand, foot and mouth disease in addition to acute neurological diseases while in brazil these viruses are more closely associated to the latter group. the aim of this research was to use the first ev-71 isolate of the northern region of brazil in molecular and seroepidemiologic studies. two (2.2%) out of 88 stool samples (44 cases of afp), collected from january 1998 to december 2000 were positive for ev-71 isol ... | 2005 | 15880216 |
| rt-pcr for confirmation of echovirus 30 isolated in belém, brazil. | echovirus (echo) 30 or human enterovirus b is the most frequent enterovirus associated with meningitis cases. epidemics and outbreaks of this disease caused by echo 30 have occurred in several countries. in brazil, echo 30 has been isolated from sporadic cases and outbreaks that occurred mainly in the south and southeast regions. we used rt-pcr to examine echo 30 isolates from meningitis cases detected from march 2002 to december 2003 in belém, state of pará, in northern brazil. the patients wer ... | 2007 | 17873993 |
| echovirus 30 associated with cases of aseptic meningitis in state of pará, northern brazil. | investigation of the aetiology of viral meningitis in brazil is most often restricted to cases that occur in the southern and southeastern regions; therefore, the purpose of this study is to describe the viral meningitis cases that occurred in state of pará, northern brazil, from january 2005-december 2006. the detection of enterovirus (ev) in cerebrospinal fluid was performed using cell culture techniques, rt-pcr, nested pcr and nucleotide sequencing. the ages of the 91 patients ranged from < o ... | 2009 | 19547870 |
