Ultrasensitive qualitative screen for SIV/HIV-2/HIV-1 by
real time polymerase chain reaction - detects but does not
differentiate SIVsmm, SIVmac, SIVagm, SIVmnd, SIVsyk, SIVcpz,
HIV-1 subtypes A, B, D, F, H and N, and HIV-2 (A and B subtypes). However, assay does not detect HIV-1 subtype C.
In the wild,
infections by primate lentiviruses occur only among African
monkeys and chimpanzees. Simian immunodeficiency viruses have
been isolated from several species of monkeys. Based on sequence
homology, the primate lentiviruses can be divided into several
groups, of which only three are important from the perspective
of primate models of AIDS: HIV-1/SIVcpz, HIV-2/SIVsmm/SIVmac,
and SIVagm. The other primate lentiviruses, e.g., SIVmnd, SIVsyk,
SIVwcm, SIVrcm, SIVdrl, etc., have not been used as yet to
develop models of AIDS. The primate lentiviruses have little or
no pathogenicity in their natural hosts and disease appears to
result only after transmission to another species.
many species of monkey are not endangered and breed well in
captivity. Large numbers of animals, especially macaques, are
readily available. Compared to chimpanzees, macaques are
inexpensive, making them suitable for vaccine studies that
require large numbers of animals. Unfortunately, with rare
exceptions, attempts to infect monkeys with HIV-1 have not been
successful. Some laboratories have reported the infection of
pig-tailed macaques (Macaca nemestrina) with HIV-1, but virus
replication in vivo was at extremely low levels and did not
cause disease. Thus, the use of HIV-1/pig-tailed macaques as an
AIDS model is not feasible.
host of SIVsmm is the sooty mangabey monkey (Cercocebus atys).
SIVsmm is the progenitor of HIV-2 and SIVmac, which appear to
have arisen due to cross-species transmission to humans and
macaques, respectively. SIVmac infection in macaque monkeys is a
well-characterized model of AIDS. HIV-2 and SIVsmm infections of
macaques resemble SIVmac infections in most respects. Rhesus (Macaca
mulatta), cynomolgus (M. fascicularis), and pig-tailed macaques
have been used in the majority of studies, although other
macaque species are also susceptible to infection.
virus isolation can be used to diagnose SIV infection, a long
incubation period is required to obtain results. Furthermore,
viral culture is neither sensitive nor specific. Viral culture
also increases the potential risk of laboratory personnel
contacting this virus. SIV detection by PCR is the most rapid,
sensitive and specific method for the diagnosis of this
