“…For example, the findings of studies conducted in Qazvin-Sari (3.73% in the North of Iran), 23 (5.8% in the north-west of Iran), 17 Shiraz (6.3% in the south of Iran), 24 and Urmia (7.8% in Northwest Iran) 19 are consistent with our results. However, the rate of contamination in Khorramabad (22.2% in the west of Iran), 18 Ahvaz (28.4% in the southwest of Iran), 25 Abadan (29.2% in the southwest of Iran), 16 Karaj (36.4% in the north-central of Iran), 26 and Tehran (38.7% in the north of Iran) 27 is very different from the obtained result in this regard in our study. In the present study, the prevalence of the Toxocara egg in the soil of the rural area was more compared to the urban area, which may be due to the existence of stray and shepherd dogs in and around the villages.…”

Background and aims: Toxocariasis caused by the larvae of Toxocara spp. is a zoonotic infection with global distribution that is considered an important health problem in the humans. The soil is regarded as the main source of the transmission of Toxocara infection to susceptible hosts. This study investigated the existence of Toxocara spp. ova in rural and urban public areas of Chaharmahal and Bakhtiari province. Methods: A total of 180 soil samples were randomly collected from 74 public places from urban and rural areas of nine counties of Chaharmahal and Bakhtiari province during May to September, 2017. The samples were examined for Toxocara spp. eggs by the modified sucrose flotation method. Results: The contamination rate of the soil samples with Toxocara spp. ova varied within 0%-18.1% in different counties. Overall, 9 (5%) out of 180 examined soil samples were found positive for Toxocara spp. ova. Of nine investigated districts, Toxocara spp. ova were observed in four counties and the highest rate of soil contamination was found in Farsan county with 18.1%. Finally, the prevalence of Toxocara spp. eggs was more in the rural areas (6.7%) compared to the urban ones (3.3%). Conclusion: This study was the first investigation regarding the contamination of Toxocara spp. eggs in the soil of public places in rural and urban areas of Chaharmahal and Bakhtiari province. According to the results, the rate of soil contamination in this region was lower compared with the other parts of Iran. Therefore, a further study is required to determine factors that may be involved in the distribution of Toxocara spp. in different areas of this province.

Introduction: The infections caused by Toxocara spp. are considered as one of the most important zoonotic diseases in the world, especially in developing countries. Human toxocariasis, particularly in children is acquired by playing in public parks. Hence, the aim of the current study was to detect Toxocara spp. in the soils of public parks of the city of Ahvaz, southwest of Iran, using the PCR and loop-mediated isothermal amplification (LAMP) methods. Methods: In this descriptive cross-sectional study, 260 soil samples were randomly collected from the different public parks of the city of Ahvaz. After preforming zinc sulfate (ZnSO4) flotation technique, the DNA samples were extracted from the isolated Toxocara spp. egg. Lastly, the extracted DNA was used for PCR and LAMP-based molecular detection. Results: Of 260 specimens, 57 (21.9%) samples were found positive for Toxocara spp., using the PCR method, out of that 38 (14.6%) samples were positive for T. canis and 19 (7.3%) samples were positive for T. cati. Also, of 260, 81 (31.1%) cases were positive for Toxocara species, using the LAMP method, among them 51 (19.6%) samples were found positive for T. canis and 30 (11.5%) samples were positive for T. cati. Kappa (κ) coefficient between PCR and LAMP showed a strong agreement (0.766, P-value=0.002). Conclusion: Our data showed a relatively high outbreak of Toxocara spp. in the public parks’ soils of the city, using the PCR and LAMP methods. Since the parasite can cause human toxocariasis particularly in children; thus, the health authorities of the city of Ahvaz and other similar cities, particularly in developing countries must pay more attention to the hygiene of the public parks’ soils.
