Extraction of the DNA of Giardia lamblia isolated from vegetables and fruits in a simplified way and its diagnosis using Nested-PCR

In this study, this parasite was diagnosed based on microscopic diagnosis of isolated samples of vegetables and fruits, as well as molecular diagnosis. The possibility of isolating parasites from vegetables and fruits and extract DNA to be used in most laboratories were verified in this study .The prevalence ofGiardia lamblia were estimated on vegetables and fruits without the need to purchase a special extraction kit. .The prevalence of Giardia on fresh vegetables was estimated by using wet direct swab with Lugol ’s iodine dye in microscopic examination, at a rate of 4 positive samples out of 230 of all studied species, or 1.7%. DNA extraction was carried out for all samples, and 102 DNA samples were extracted from all samples, with a percentage of 44.3%. Moreover, the shown results of the nested PCR test for the 16 S rRNA gene on the obtained DNA the prevalence of Giardia lamblia at a rate of 5.9% from DNA samples isolated from vegetables and fruits.
