PCR tests for all the above pathogens.
To maintain
and improve the quality of nonhuman primates used in biomedical
research, and to protect occupational safety and animal health,
the establishment and maintenance of specific pathogen free
(SPF) breeding colonies of macaques (genus Macaca) has always
been a priority. Four pathogens in particular are often targeted
for screening in NHP breeding programs: SRV, SIV, STLV and
Herpes B. Repeated screening by immunoassay is normally
performed for each of these, along with repeated PCR screening
for SRV. PCR is also used as a confirmatory or adjunct test for
SIV, STLV and Herpes B.
Simian type
D retrovirus (SRV) is enzootic in many Asian macaque
populations, where it is associated with immunodeficiency
diseases. Many infected monkeys are asymptomatic carriers of the
virus. The virus can cause animal fatalities and confound
preclinical trials and other experimental protocols.
Two other
simian retroviruses, simian immunodeficiency virus (SIV) and
simian T-cell leukemia/lymphotropic virus (STLV), are also
commonly screened in SPF monkey colonies. Like SRV, these
viruses can significantly compromise the primate immune system
and cause fatal outcomes in monkeys subject to experimentation.
Sensitive
and specific screening tests can identify macaques infected with
exogenous SIV, STLV, and SRV. A testing algorithm of repeated
antibody screening by enzyme immunoassay plus molecular
detection by PCR has proven useful for identification and
exclusion of these retroviruses from monkey colonies (Buchl et
al., 1997; Lerche et al., 1994, 1997)
Herpes B
virus, which is widespread in many macaque populations, is a
significant health threat to primate care personnel. The virus
is normally asymptomatic in macaques, but human infection with
this virus is often fatal. Monkeys immunocompromised by
experimental retrovirus infection and drug treatment are more
likely to become B virus shedders. Although B virus is the most
challenging infection to eliminate from an SPF population,
active screening by serological testing plus molecular detection
in suspicious cases can help to eliminate the virus from
colonies. (Buchl et al., 1997).

Specimen requirements:
0.5 ml whole blood in EDTA (purple top) or ACD (yellow top)
tube, or 0.5 ml serum or plasma.
For specimen
types other than those listed here, please call to confirm
specimen acceptability and shipping instructions.
For all
specimen types, if there will be a delay in shipping, or during
very warm weather, refrigerate specimens until shipped and ship
with a cold pack unless more stringent shipping requirements are
specified. Frozen specimens should be shipped so as to remain
frozen in transit. See shipping
