The aim of this study was to determine by real-time RT-PCR the presence and relative levels of tumor necrosis factor alpha (TNF-a) and interleukin 1 alpha (IL-1a) mRNA expression in intestinal mucosa of healthy and with enteropathy young alpacas (Vicugna pacos) from Cusco, Peru. A total of 71 samples of jejunum from 0 to 45 days old healthy (n=38) and diseased (n=33) alpacas were processed. Total RNA was extracted from samples and to the synthesis of DNA complementary strand (cDNA) by reverse transcription (RT) was done. Subsequently, conventional PCR and real time RT-PCR was conducted. The results showed that 98.6% (70/71) of the samples amplified a specific product of 251 pb for TNF-a and 100% (71/71) of the samples amplified a specific product of 172 pb for IL-1a, evidenced in the agarose gel during electrophoresis. Analysis of dissociation curves determined that: a) the products ampl...
