Hepatitis C virus (HCV) by PCR
- Ultrasensitive qualitative detection of hepatitis C virus by
reverse transcription coupled real time polymerase chain
- Detection of total antibodies to hepatitis C virus in nonhuman
virus (HCV) is member of the Flaviviridae family and is the
major causative agent of parenterally transmitted non-A, non-B
hepatitis worldwide. Genetic analysis of this virus led to the
discovery of six major genetic groups (genotypes 1-6) and
multiple minor genetic groups (subtypes 1a, 1b, 2a, 2b, etc.).
To date, chimpanzees represent the only appropriate animal model
for studying HCV infection, as they are easily infected with
human hepatitis C virus and develop acute or chronic hepatitis (Farci
and Purcell, 1993; Schlauder et al., 1991). HCV infection in
other wild or captive non-human primates is still controversial
and the possibility of such infection cannot be ruled out (Korzaya
et al., 2002; Peli et al., 2002).
tests currently available either detect direct antibodies to HCV
(anti-HCV) or HCV RNA. Anti-HCV indicates prior exposure to HCV
but does not distinguish between cleared and active infection.
An additional immunoassay such as RIBA may confirm the status of
infection, but such immunoassays have a high indeterminate rate.
Detection of HCV RNA by reverse transcription PCR offers a more
rapid, sensitive and specific method for diagnosis of active HCV
