“…In Iran, the highest prevalence of hydatid cysts in humans, as well as the highest rate of Echinococcus infection in the final hosts (mainly dogs), has been reported in the southern regions of the country [ 1 ]. In a study by Asadi et al, on 220 municipal workers in Urmia, northwestern Iran, anti-hydatid cyst antibodies were detected in 2.3% of the studied individuals [ 2 ]. In two recent studies conducted in Fars province, southern Iran, the seroprevalence of hydatid cyst among children living in a rural area and blood donors was reported to be 6.7 and 5.6%, respectively [ 3 , 4 ].…”

Cystic echinococcosis (CE) is a common zoonotic infection in all provinces of Iran, especially in areas where people live on agriculture and animal husbandry. The current cross-sectional population-based study is aimed at determining the seroprevalence of CE in Kavar County, Fars province, southern Iran. Blood samples were collected from 1500 individuals (749 males and 751 females). Anti-hydatid cyst antibodies were detected, using a recombinant B8/1 antigen of Echinococcus graunlosus in an ELISA system. Multivariate logistic regression analysis was used to find out the independent risk factor for CE seropositivity. Anti-hydatid cyst antibodies were detected in the sera of 131 out of 1500 participants, corresponding to a seroprevalence rate of 8.73%. With a statistically significant difference ( p < 0.05 ), the seroprevalence of hydatid cyst in males and females was 5% and 7%, respectively. Differences in the seropositivity of hydatid cysts were also statistically significant by occupation ( p < 0.05 ). The seroprevalence of hydatid cyst was significantly higher in the age group of 35-45 years than in other age groups ( p < 0.05 ). Multivariate logistic regression showed that only age was associated with seropositivity to CE ( OR = 2.23 , 95% CI: 1.33-3.72). Moreover, there was a statistically significant association between seropositivity to hydatid cysts and underlying diseases such as hypertension ( p = 0.049 ) and fatty liver ( p = 0.048 ). The findings of this study indicate that the seroprevalence rate of CE is relatively high in the Fars province, southern Iran, and this high rate of infection is mainly linked to people’s jobs and lifestyles.

“…For example, Shafei et al in North Khorasan Province in northern Iran reported a 3.96% prevalence among 932 referred individuals (12). In another study on 220 municipal workers in the northwest of Iran by Asadi et al, the seroprevalence of cystic echinococcosis was estimated at 2.3% (13). The ELISA test was used in most studies due to its high performance, acceptable sensitivity and specificity, and cost-effectiveness.…”

Background: Hydatid cyst is a global infectious disease caused by the larval stage of Echinococcus granulosus. The annual incidence of human cystic echinococcosis (CE) in Iran varies from 0 to 61 in 100,000 cases, depending on geographical conditions, epidemiological factors, and diagnostic methods. Studies showed that E. granulosus infection is one of the most important health problems in most parts of the country. Methods: This descriptive cross-sectional study was conducted on 400 cases referring to Shahid Ghodoosi and Shahid Alimoradi hospital laboratories in Nahavand, Hamadan, Western Iran. IgG antibodies against hydatid cysts were evaluated by the commercial enzyme-linked immunosorbent assay (ELISA) kit, and socio-demographic data were collected using a questionnaire. Then, data were statistically analyzed by SPSS software. Results: Out of 400 subjects in this study, five (1.25%) were positive for CE IgG antibodies by the ELISA method. Two (40%) females and three (60%) males were reported positive for CE IgG via the ELISA Hydatid test. Rural residents consisted of the majority of positive cases (80%). Nearly all of the hydatid-infected subjects were categorized in the age group above 50. Moreover, housewives and self-employed businesses were identified as the two occupations with the highest antibody titers against E. granulosus. In addition, no significant statistical difference was observed in variables. Conclusion: Although the frequency of hydatid cyst infection in Nahavand is lower than the average proportion confirmed by previous studies in the country, due to the numerous records of hydatid cyst disease in the region, the establishment of health programs is regarded essential to control this parasitic infection.

Introduction Occupation plays an important role in the spread of infectious diseases in humans. Toxoplasmosis and hydatidosis are world-wide diseases with different routes of transmission. This study aimed to investigate the prevalence of toxoplasmosis and hydatidosis and risk factors associated with these diseases among the butchers of Tabriz City, the northwest of Iran. Methods In this case-control study conducted in Tabriz city in 2023, 250 serum samples were collected from butchers (n = 125) and outpatients referred to Imam Reza Hospital (n = 125) and. The ELISA test was used to identify IgG and IgM antibodies against toxoplasmosis and IgG antibodies against hydatidosis. The results were analyzed by statistics tests using SPSS v. 16 software. Risk factors’ association was tested using Chi square or logistic regression analysis. Results The results indicated that 66/125 (52.8%) cases and 40/125 controls (32%) were positive for toxoplasmosis IgG antibody. Also, 5/125 (4%) and 1/125 (0.8%) were positive for toxoplasmosis IgM antibody in the case and control groups, respectively. In addition, 10/125 people (8%) were positive for anti-hydatidosis IgG antibody in the case group, while no positive cases were found in the control group. The main risk factors for toxoplasmosis were age (OR: 1.014), education level (OR: 0.638), and work experience(OR: 1.695), these factors for hydatidosis included age and education level (OR: 1.765 and 0.271) respectivily. Conclusions Our results suggest the high prevalence of toxoplasmosis and in butchers of Tabriz, which required special attention and basic measures. Moreover, the prevalence of hydatidosis IgG antibodies also requires more attention to be focused on breaking the transmission and reducing the infection.
