Investigation of antibodies against yellow fever virus, and Zika virus using adapted neutralization test, using liver homogenates from non-human primate carcasses.

Legend: RT-qPCR: reverse transcription polymerase chain reaction. PRNT: plaque reduction neutralization test. sample identification. P: positive; N: negative and -: not available. YFV: Yellow fever virus. ZIKV: Zika virus. A. guariba: Alouatta guariba; C. penicillata: Callithrix penicillata; C. geoffroyi: Callithrix geoffroyi; C. personatus: Callicebus personatus; C. nigrifrons: Callicebus nigrifrons. Carcasses were previously classified regarding the preservation status as good (G), intermediate (I), or bad (B) (see Sacchetto et al, 2020, reference 2). Results of RT-qPCR performed on NHP liver/or brain samples with information on the cycle quantification value (Cq) are shown (see Sacchetto et al, 2020, reference 2). The neutralization values observed in adapted PRNT using YFV or ZIKV are show per dilution. (XLSX)
