“…Result didn't show any positive samples from geothermal hot spring water of Bandar Abbas. Some studies showed that based on the morphological characteristics of amoebae, 42% of warm spring waters of southwest of Iran are positive for Acanthamoeba, and others revealed that genotype T2, T4, T15 could exist in such environments [12,31]. No significant statistical differences were observed between pH variable and frequency of Acanthamoeba using culture and molecular methods (p-value = 0.014) and p-value (p = 0.116) respectively.…”

Objective These amoebas can cause dangerous illnesses when they accidentally enter the human body, so it is necessary to determine various forms of organisms in water resources to prevent the danger they can cause and risks to human health. Currently, in Bandar Abbas, there is no sufficient information about the distribution of Acanthamoeba, and we intended to study its frequency and determine the related genotypes. Results Out of 83 water samples collected from different resources in the city, 31 plates (37.3%) were found to be positive for free-living amoebae. Of these, five were identified as Acanthamoeba (6%) by culture method and 8 (9.6%) by molecular method. Positive sample sequence analysis enabled us to distinguish two genotypes of T4 (7 cases) and T15 (1 case) in this study.

“…Acanthamoeba species encompasses at least 15 species of free living amoebae that have been isolated from a wide range of environments ranging from natural habitats like soil, salt water and fresh water, to domestic sources like tap water, air conditioning units and sewage systems 17 . The researchers have been reported that Acanthamoeba (genotype 4) is pathogen and common in environmental sources 18 . We found that only Acanthamoeba (genotype 4) in soil and water samples as supported in previous studies about Acanthamoeba.…”

Objective: The soil and waterborne parasitic infections rate is high degree in developed and developing countries. Migratory workers have greater exposure to these parasitic infections and a lot of morbidity due to these infections in workers. For this reason, we aimed to investigate the presence of soil and waterborne parasites in the Gaziantep Organized Industrial Zone of southeast Turkey. Methods: A total of 25 environmental samples (18 soil samples and 7 water samples) were taken from The Gaziantep Organized Industrial Zone, in two different seasons (summer and winter). All of the samples were screened for parasites using microscopic examination and culture methods. The parasites were genotyped with polymerase chain reaction and DNA sequencing analysis. Results: The prevalence of soil and water transmitted parasites was found to be positive 52% (13/25) in summer while there is no any parasites in winter. It was found 22.3% (4/18) Acanthamoeba (genotype4), 16.6% (3/18) Ascaris lumbricoides, 11.1% (2/18) Strongoides stercoralis in soil samples and 14.3% (1/7) Acanthamoeba (genotype 4), 42.9% (3/7) Blastocystis (subtype3) in all of water samples. Conclusion: The migratory worker waves have always shaped the ethnic composition and public health problem of the province of Gaziantep. Climate change has the potential to influence prevalence of parasite and our study has shown that increased prevalence of parasite in summer. The global target for the coming years should be to remove the deaths from earth and waterborne parasitic infections in the worker populations. Thus, we prevent the distribution of parasitic infections in our country.
