Aim:
A previous study confirmed the contamination of water sources with this parasite in Arak, Markazi Province, Iran. The current study investigated soil sources and determined the predominant genotype of Acanthamoeba in this region of Iran.
Material And Methods:
Forty-eight soil samples, collected from different regions of Arak, Markazi province, Iran, were evaluated in this study. The samples were processed and identified by culturing on a specific medium, performing PCR assay, and sequencing the PCR products. Finally, using the NCBI database, the genotypes were determined.
Results:
Of 48 soil samples, 33.3% and 31.25% were contaminated with Acanthamoeba according to the culture and molecular assays, respectively. The majority of these isolates belonged to the T4, T5 and T6 genotypes of Acanthamoeba.
Conclusion:
The genotypes of most isolates from soil samples in Arak similar to other regions of Iran belong to T4 genotype of this parasite. New sequence accession numbers include MG066681 and MG298785-MG298794.
Insights
Soil samples in Arak, Iran, were analyzed for Acanthamoeba contamination. The study identified T4, T5, and T6 genotypes, with T4 being predominant, similar to other Iranian regions.
Area of Science:
- Environmental microbiology
- Parasitology
Background:
- Acanthamoeba is a ubiquitous protozoan parasite.
- Previous studies confirmed Acanthamoeba contamination in Arak's water sources.
Purpose of the Study:
- To investigate soil as a potential reservoir for Acanthamoeba in Arak, Iran.
- To determine the predominant Acanthamoeba genotypes in the region's soil.
Main Methods:
- Collected and analyzed 48 soil samples from Arak, Markazi Province, Iran.
- Employed culture-based methods and PCR assays for Acanthamoeba identification.
- Sequenced PCR products and utilized the NCBI database for genotype determination.
Main Results:
- Acanthamoeba contamination was detected in 33.3% of soil samples by culture and 31.25% by molecular assays.
- The predominant genotypes identified were T4, T5, and T6.
- Genotype T4 was the most prevalent, consistent with findings in other parts of Iran.
Conclusions:
- Soil in Arak harbors Acanthamoeba, with T4 genotype being the most common.
- This finding highlights the importance of soil as a potential source of Acanthamoeba in the region.
- New sequence accession numbers (MG066681, MG298785-MG298794) were assigned for identified isolates.

Sampling Methods: Sample Types
Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...
Sampling Plans
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
Sample Handling
Samples should be transported carefully from collection points to the laboratory. They should be properly sealed and clearly labeled to prevent cross-contamination. To preserve the sample integrity, optimal temperature conditions during transport are essential. This could involve using...
