The development of HIV research laboratories in the Royal Thai Army Medical Department.

The development of HIV research laboratories at the Armed Forces Research Institute of Medical Sciences (AFRIMS), Royal Thai Army Medical Department in supporting of HIV-1 vaccine trials in Thailand was implemented in 1991. The collaboration between AFRIMS, Royal Thai Army Medical Department, and the US Military HIV Research Program with the ultimate goal to conduct the HIV-1 vaccine trial phase III. The HIV serology lab was set up for surveillance program in military recruits.

Quantification of HIV-1 RNA load by one-tube-one-step RT PCR and real time PCR assay with TaqMan probe.

Objectives: To develop a less expensive assay to calculate HIV-1 viral load for use in resource-limited countries.

Material And Method: An In-house One-tube-one-step Viral Load Assay (IOVA) was developed by using real-time PCR-based with TaqMan probe. Primers and probe were designed from the conserved region of sequences from all HIV subtypes.

A new circulating recombinant form, CRF15_01B, reinforces the linkage between IDU and heterosexual epidemics in Thailand.

HIV-1 subtype B and CRF01_AE have been in circulation in Thailand and Southeast Asia for more than a decade. Initially separated by risk group, the two strains are increasingly intermixed, and two recombinant strains of essentially reciprocal structure have been recently reported. Here we identify additional CRF_01B recombinants and provide the evidence that HIV-1 strains now pass freely between the two high-risk populations.
