results the mean age of children was 6.5 ± 4.2 years. the frequency of positive results for hbsag, anti-hbs and anti-hcv in all age groups were 12 (3.6%), 47 (14.2%) and 2 (0.6%), respectively. anti-hiv was not detected in any of the children's serum samples. the frequency of positive results for hbsag was significantly higher in children older than six years than in other age groups. conclusio...
We developed a rapid and sensitive method for the routine detection of all members of the enterovirus genus in different clinical specimens by using real-time TaqMan quantitative PCR. Multiple primer and probe sets were selected in the highly conserved 5'-untranslated region of the enterovirus genome. Our assay detected all 60 different enterovirus species tested, whereas no reactivity was obse...
The picornaviruses are a diverse group of viral pathogens that together comprise the most common causes of infection of humans in the developed world. Within the picornavirus family are three well-known groups of human pathogens--the rhinoviruses, the enteroviruses (including polioviruses, coxsackieviruses and echoviruses) and the hepatoviruses (including hepatitis A virus). This article will f...
Rodents are important reservoir hosts of many important zoonotic viruses. The family Picornaviridae contains clinically important pathogens that infect humans and animals, and increasing numbers of rodent picornaviruses have recently been associated with zoonoses. We collected 574 pharyngeal and anal swab specimens from 287 rodents of 10 different species from eight representative regions of Ch...
Avian encephalomyelitis is caused by an Hepatovirus and primarily affects chickens. Chickens of all ages are susceptible to the virus, but the nervous symptoms are manifested only in young chicks, between one to five weeks of age. During the last thirty years, avian encephalomyelitis appeared to be well controlled by breeder vaccination. However, the increase of the number of cases is causing c...
1. 9 human volunteers, convalescent from infectious hepatitis experimentally induced by a strain of virus employed in this laboratory, were resistant when reinoculated with the same strain of virus, 6 to 9 months later. 2. 8 out of 12 previously healthy control subjects developed infectious hepatitis with jaundice following administration of this same material. 3. The demonstration of homologou...
Introduction: Hepatitis A is caused by a virus of the family Picornaviridae, genus Hepatovirus. It fecal-oral disease that can cause jaundice, nausea, abdominal pain, fever, dark urine, among other symptoms.
