Abstract

Simian type D retroviruses (SRVs) are one of the causative agents of simian acquired immunodeficiency syndrome (AIDS) in Asian macaques. In the past, SRV isolates from macaques had only been identified at the US primate centers, outside the country of origin and after the animals had been introduced into a new environment. In this study, we report the first isolation, cultivation and molecular characterization of the type D simian retrovirus naturally infecting wild caught macaques in their natural habitats in the country of origin, in this case, Indonesia. When peripheral blood mononuclear cells (PBMC) from Macaca fascicularis (Mf) and M. nemestrina (Mn) were co-cultured with Raji human B-cell line, syncytia were observed microscopically and confirmed by immunofluoresence assay using antibody to SRV-2. Immunoblot analysis of purified Mf-ET1006 from cell culture supernatants demonstrated that the viral core and envelope proteins reacted with rabbit anti-SRV. Sequence analysis of Mf isolates in the viral envelope region revealed high homology to SRV-2 (94-96%). On the other hand, the homologies in the envelope region of Mn isolates were less than 80% to SRV-1, SRV-2, SRV-3 and Mf isolates. This study suggests that the isolate from Mn may be different from any other published SRV isolates.

Abstract

In this study, we isolated the simian betaretrovirus serotype-2 (SRV-2) reverse transcriptase (RT) gene from infected Indonesian cynomolgus monkey (Macaca fascicularis). The gene was then cloned in Escherichia coli expression system. The SRV-2 RT gene is located between nucleotides 3284-4925 in the polyprotein (Pol) region encodes 547 amino acids. Analysis of expression using SDS-PAGE and western blot techniques showed a specific band of 64.9 kDa, indicating SRV-2 RT recombinant enzyme. Purification of SRV-2 RT recombinant enzyme produced 312 μg mL-1 protein with 7.1 U μL-1 enzyme activities. Application of this recombinant enzyme in reverse transcription-PCR (RT-PCR) of β-globin and β-actin genes produced DNA fragments of 206 and 350 bp, indicating amplification of β-globin and β-actin genes, respectively. Therefore, the expressed SRV-2 RT enzyme was proven to be functional, although the activity was low.
