Antibodies against Col-SK Virus in Mexican Sera

Columbia SK Group of Viruses

“…technique) among the sera from healthy African pygmies native to the tropical forest (see Table 29). A different situation apparently exists in certain semitropical countries of Central and South America, i. e. in Mexico and in Surinam, where several authors encountered an unusually high incidence of positive immune reactions against Col SK virus among healthy individuals living in more or less isolated rural areas (JUNGEBLUT and BAUTISTA 1954;DALLDORF 1952;GAJDUSEK 1955;CoLLIER 1955) (see Table 29). The age distri- bution of these antibodies in a group of Mexicans, as given by DALLDORF (Fig.…”

Human Febrile Illness Caused by Encephalomyocarditis Virus Infection, Peru

“…This fi nding suggests that additional cardioviruses may be pathogenic for humans. Serologic studies also indicate that humans have been infected by EMCV or immunologically related viruses (17)(18)(19)(20)(21)(22). Antibody prevalence varied somewhat from study to study, but seropositivity rates tended to increase in persons of advancing age, consistent with a continuous risk for in- …”

“…A novel cardiovirus, SAFV, isolated from the stool of an infant with fever of unknown origin, recently was reported (15). SAFV and SAFV-like viruses also have been detected in nasopharyngeal aspirates from children with respiratory illness (16) or gastroenteritis (17,18). In all of these cases, however, virus was isolated only from specimens obtained from nonsterile sites, making the patients' symptoms impossible to associate unequivocally with the cardiovirus infection.…”

“…The original detection and identifi cation of SAFV used a combination of traditional virus isolation in cell culture and creation and characterization of a cDNA library by DNase sequence-independent singleprimer amplifi cation (15,16). A panviral DNA microarray also has been used to detect SAFV and SAFV-like human cardioviruses (18). Such laborious methods are not practical for routine diagnostic testing.…”
