RESEARCHthe potential for human infection. Macaques have adaptedto urbanized human environments, and contact betweenhumans and macaques can occur in a variety of contexts(e.g., feeding in public recreational areas, capture of wildmacaques for the pet trade or biomedical research colonies,consumption, or population management by wildlifeauthorities). Human–macaque contact can result in bites,scratches, and indirect exposure to macaque body fluids(16,17). Simian foamy virus, a nonpathogenic retrovirusfound in nonhuman primates including macaques, has beentransmitted during occupational exposure to macaques viabites and scratches in many of the aforementioned contextsand in agricultural, suburban, and urban environments (18–20). Zoonotic transmission of simian foamy virus to humanshas been demonstrated in Indonesia (18) and Bangladesh(19). Because exposure to MaHV1 can occur throughsimilar routes (8), its transmission under circumstancessimilar to those of transmission of simian foamy virus inAsia is plausible.In Peninsular Malaysia, conflict between humans andmacaques in residential and public areas results from lossof macaque habitat, successful macaque adaptation to humanenvironments, and subsequent macaque overpopulation.As a result, the Department of Wildlife and NationalParks (DWNP) in Peninsular Malaysia implemented a macaquepopulation management program, which includesthe removal or translocation of macaques from a conflictarea. The possibility of exposure to MaHV1 during macaquecapture and transport presents a potential occupationalhazard to wildlife personnel.Our aim with this study was to describe the prevalenceof MaHV1 shedding among wild-caught long-tailedmacaques after capture and transport in Peninsular Malaysia.This study represents a step toward understandingthe potential for zoonotic transmission of MaHV1 outsidethe laboratory.Materials and MethodsCapture and Sample CollectionIndependently of this study, DWNP, as part of their macaquemanagement program throughout Peninsular Malaysia,captured and transported macaques from 6 states(Johor, Perak, Pahang, Pulau Pinang, Selangor, and NegeriSembilan) to DWNP holding facilities. Capture and opportunisticblood sampling was performed by DWNP andEcoHealth Alliance during September–November 2009,July–October 2010, and July 2011. The macaques capturedhad been free ranging and lived in the peripheral vegetationof rural, suburban, and urban communities in severalstates of Peninsular Malaysia. Trapped animals were transferredinto transport cages and taken to the nearest localDWNP facility, where they were held up to 72 h beforebeing transported to the DWNP headquarters in KualaLumpur or relocated to a new area. Macaques were kept ingroups in cages and provided with food and water throughoutthe holding period. Animals were captured in accordancewith the protocols and guidelines of the Manual forHuman–Macaque Conflict Management in Peninsular Malaysia(21). This study was conducted under InstitutionalAnimal Care and Use Committee approval no. 18048 fromthe University of California (Davis, CA, USA). When handlingand sampling macaques, personnel involved with thisstudy wore personal protective equipment (PPE; e.g., eyeprotection, double-layered nitrile gloves, Tyvek coveralls,and P100 respirators) (22). Blood and swab samples werecollected from each animal at its arrival at the headquartersor at the local DWNP facility before relocation. Macaqueswere immobilized with an intramuscular injection of acombination of 5 mg/kg ketamine and 5 mg/kg xylazine(21). After immobilization, oropharyngeal swab and urogenitalswab samples were collected (when possible, urinewas also collected by cystocentesis). The samples wereplaced in 2 mL cryovials (Nalgene Nunc International,Rochester, NY, USA) with 500 μL NucliSens lysis buffer(bioMérieux, Marcy l’Étoile, France) and immediatelystored at -80°C. Macaque weight, body condition, sex, andapproximate age were recorded. The age of the animalswas determined by assessing their weight, body size, andthe development of their incisors and genitals (23). Macaqueswere categorized as adult (>7 years), subadult (3–6years), or juvenile (1–3 years). The sex and age of 2 animalsand the sex of 1 adult animal were not recorded.Molecular TestingThe samples were vigorously mixed; 100 μL of the samplewas used for mechanical nucleic acid extraction by use ofthe NucliSENS miniMAG system (bioMérieux). The extractednucleic acid was eluted with 60 μL of buffer. PCRwas performed as previously described and validated byScinicariello et al. (13). Briefly, MaHV1 primers (B virus1, 5′-ACCTCACGTACGACTCCGACT-3′; and B virus2, 5′-CTGCAGGACCGAGTAGAGGAT-3′; 2.5 μmol/L)were each added to the extraction product and HotStarTaqPlus Master Mix (QIAGEN, Hilden, Germany). The productwas placed in a thermocyler at 94°C for 5 min and thenunderwent 30 cycles as follows: 94°C for 1 min, 56°C for1 min, and 72°C for 1 min. The products (10 μL) were thenanalyzed by electrophoresis on 1% agarose gels. Of the≈10% of samples that were positive by PCR, 14 PCR productswere randomly selected and purified with a PCR purificationkit (QIAGEN) and sequenced by using the sameprimers to confirm identity. Sequences were 128 bp andwere analyzed by using a BLAST search of GenBank (24).Because PCR is reported to be highly specific (13) and all 14PCR products showed 93%–100% nucleotide homology to1108 Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 21, No. 7, July 2015
