Molecular identification of waterborne free living amoebae (Acanthamoeba, Naegleria and Vermamoeba) isolated from municipal drinking water and environmental sources, Semnan province, north half of Iran.
Experimental Parasitology 2017 December
The present study tested 80 samples of municipal, geothermal and recreational water samples for the occurrence of waterborne free living amoebae (FLA) including Acanthamoeba, Balamuthia mandrillaris, Vahlkampfiids and Vermamoeba in Semnan province, North half of Iran. Four sets of primers including JDP1,2 primers, ITS1,2 primers (Vahlkampfiids), 16S rRNABal primers (Balamuthia mandrillaris) and NA1,2 primers (Vermamoeba) were used to confirm the morphological identification. From the 80 water samples tested in the present study, 16 (20%) were positive for the outgrowth of free living amoebae based on the morphological page key. Out of the 34 municipal water samples, 7 (20.6%) were positive for outgrowth of Free living amoeba, belonging to Vermamoeba, Naegleria and Acanthamoeba using molecular tools. Three out of the six investigated hot springs were also contaminated with Naegleria spp. Sequencing of the ITS1,2 region of the Vahlkampfiid isolates revealed the highest homology with N. gruberi (2 isolates), N. australiensis (1 isolate) and N. pagei (3 isolates). This is the first report of N. gruberi in the country. Using morphological and molecular analysis, Balamuthia mandrillaris was undetected in all the water samples. The present study further confirmed the occurrence of potentially pathogenic waterborne free living amoebae in habitats with high human activity. It is of utmost importance that more studies are conducted to evaluate the niches of B. mandrillaris and N. fowleri in Iran and worldwide. Such investigations regarding the relevance of FLA as a hazard to humans, should be brought to the notice of the health authorities.
