KUALA LUMPUR : A consultant molecular geneticist said he would not expect to see sperm on the rectal swab stick sample taken from Mohamad Saiful Bukhari Azlan as bacterial overgrowth would have destroyed it, the High Court here heard today.
Dr Brian Leslie McDonald (pix), 60, from Australia said this when Datuk Seri Anwar Ibrahim’s lawyer Ram Karpal Singh asked about the condition of the rectal swab stick taken on June 28, 2008.
Ram said the sample was taken from Saiful’s anus 56 hours after the alleged sodomy on June 26, sealed and kept by the investigating officer for two days (in a cabinet) in his office i.e. 48 hours at room temperature, before it was sent to the Chemistry Department for analysis.
“I personally would not see any evidence. Bacterial overgrowth would have destroyed it within 48 hours. I would not expect to see sperm,” McDonald said.
