Hepatitis A seroprevalence in South Africa: Are we in epidemiological transition?
Hepatitis A virus (HAV) is the most common cause of viral hepatitis worldwide. Infection with HAV is vaccine preventable, however, a vaccine against HAV is not included in the Expanded Programme on Immunization in South Africa (SA). South Africa was considered to be a high endemic country for …

HEPATITIS A VIRUS: GROWTH CHARACTERISTICS, PURIFICATION, AND CAPSID GENE ORDER (PEPTIDES, IMMUNOREACTIVITIES, POLYPEPTIDES).
A human isolate of hepatitis A virus (HAV) strain HAS-15 was adapted to rapid growth FRhK-4 cells and a one-step growth curve was determined. Detectable virion production was absent for approximately 20 h post-infection (p.i.) and was followed by a 4-day logarithmic phase of virus production. A …

Evasion of RIG-I/MDA5 and TLR3-mediated innate immunity by hepatitis A virus
… and thus become targets for viral interference. Hepatitis A virus (HAV), a hepatotropic picornavirus, is capable of blocking IRF3 activation and type I IFN expression in cell culture, but the exact mechanism(s) remains undefined. Our studies revealed that HAV disrupts RIG-I/MDA5-mediated …

Evidence-based vaccinology: supporting evidence-informed considerations to introduce routine hepatitis A immunization in South Africa
Hepatitis A is a vaccine preventable disease caused by the Hepatitis A Virus (HAV). Currently, South Africa is classified by the World Health Organization (WHO) as a high hepatitis A endemic region where 90% of children are assumed to be “naturally immunised” following HAV exposure before the age …

Wastewater-based Surveillance for Hepatitis A and C in an Inflow- and Infiltration-Impacted Rural System
… are several risk factors in this region for hepatitis infection. Hepatitis is an inflammation of the liver which can develop into chronic hepatitis and is caused by one or more of the five primary strains (A-E). Hepatitis A (HAV) is typically spread via the fecal oral route and consumption of …

A retrospective review of acute liver failure in children admitted at Red Cross War Memorial Children's Hospital
… 37.5 % of cases (n=9, 2 of whom had autoimmune hepatitis comorbidity) and hepatitis A was most common infectious cause (n=4, 44%). Causes were indeterminate in 29.2%. Two patients had autoimmune hepatitis without co-morbidity; Reye syndrome 12.5% and 17% had miscellaneous causes. Transaminases …

Marcadores das hepatites tipo A e B em 91 pacientes com icterícia: correlação clínico-patológica
Markers of viral hepatitis types A and B were investigated in 91 patients. Results allowed the patients to be classified into 4 group, the first (37 patients) characterized as hepatitis A, the second (35 patients) as hepatitis B, the third (11 patients) with neither A nor B markers and the fourth …

MxA-Genexpression in peripheren mononukleären Blutzellen: ein sensitiver Marker für die Aktivität von endogenem und exogenem Typ-I-Interferon
… untersucht. Patienten mit akuter Hepatitis A zeigten eine starke Aktivierung des IFN-Systems, wohingegen Patienten mit akuter Hepatitis B und C nur mäßig erhöhte MxA-Werte aufwiesen. Es konnte gezeigt werden, dass Patienten mit chronischer HCV-Infektion, im Gegensatz zu chronisch …

Microfluidic chips for combinatorial screening applications
… to key fragments of the viruses HIV, HPV, Hepatitis A and Hepatitis B were tested against four different molecular beacons, each complementary to one of the four virus target oligonucleotides. The result of this combinatorial screening chip indicated strong fluorescent values for the …

HIV and other sexually transmissible infections in a cohort of HIV negative homosexual men in Sydney
… of men aged under 25 years were seronegative to hepatitis A and B infection. The prevalence of hepatitis C (HCV) was 0.85%, which was close to that of the general population. HCV infection was strongly associated with injecting drug use (OR 60.43, 95% CI 6.70-544.79), and sexual transmission was …

Epidemiology, molecular characterisation and tropism of the Hepatitis G Virus / GBV-C
The hepatitis G virus and GBV-C are recently discovered variants of the same virus belonging to the family Flavivirus (HGV/GBV-C). Although initially thought to be a hepatitis virus, it has been shown to have no association with liver disease. No work has been performed on the prevalence or …

Metagenomic identification and characterisation of emerging and re-emerging viruses causing disease in febrile patients.
… virus, GB virus C (human pegivirus) and hepatitis B virus were identified in 36 PCR-negative Sierra Leonean patient samples using metagenomics. The detection of EBOV was surprising because the patients tested negative for EBOV RNA using a qRT-PCR assay at the time of sampling; further …
