*Simian foamy virus (SFV) seroprevalence for 2004 samples determined using enzyme immunoassay. Subsequent samples screened as part of the whole-virus multiplex flow cytometric assay (11).
†Simian immunodeficiency virus (SIV), simian retrovirus (SRV), Cercopithecine herpesvirus 1 (CeHV-1), simian T-cell lymphotropic virus (STLV) seroprevalence for 2004 samples determined by using multiplex microbead assay (10); seroprevalence for subsequent samples determined by using whole-virus multiplex flow cytometric assay (11).
‡Rhesus cytomegalovirus (RhCMV) seroprevalence for the 2004 samples (n = 40) determined by ELISA according to previously published protocols (12). Subsequent samples not screened.
§Age class determinations made on the basis of dental eruption sequence and morphometrics: young juvenile, <1 y of age; older juvenile, 1–3 y; subadult, 3–5 y; adult, >5 y.
