Methods: DNA was extracted from protoscoleces and was utilized by PCR for strain identification. Total RNA was prepared with RNeasy protect mini kit from E. granulosus (Iranian G1 strain) protoscoleces collected from naturally infected sheep with hydatid cyst. Recombinant AgB16 kDa was produced using pETDuet as vector and evaluated by ELISA method. A panel of sera including hydatid cyst-infected individu­als (n=72), healthy individual (n=48), toxoplasmosis (n=4), strongyloidosis (n=4), kala-azar (n=5) and tuberculosis (n=5) were examined using this recombinant antigen. Results: Recombinant protein was purified by affinity chromatography using His-Tag column. After purifica­tion, recombinant protein was confirmed by western blot analysis using His Tag monoclonal anti­body or hydatid positive human serum. The sensitivity, specificity; positive and negative predictive values were calculated as 93.5%, 95.6%, 96% and 92.9%, in that order. The cut-off point was detected 0.3 for rAgB16. Conclusion: While the produced recombinant AgB16 kDa showed promising results in diagnosing human hy­datidosis, but more investigations should be implemented to reach an accurate gold standard. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/140 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/140/139

We evaluated the effectiveness of sodium selenite and zinc sulphate as known immunomodulator materials, in combination with Glucantime® in treatment of cutaneous leishmaniasis lesions resulting from Leishmania ma­jor in susceptible animal model. Methods: Thirty three female mice weighing 18-20 g at the age of 7-8 week infected with L. major were randomly divided into 3 groups: group1:  treated by sodium selenite (0.35 mg/kg for 30 days), group2: treated by zinc sulphate (2 mg/kg for 30 days) and group3: treated by distilled water (0.01 ml/gr body weight for 30 days) as control. All groups received Glucantime® as a standard anti- leishmanial agent (60 mg/kg, ip) for 14 days. To assess the results of treatment measurement of lesions size and parasitological tests were done weekly. Results: The lesion sizes increased continuously in sodium selenite group .Although, in zinc group did not in­crease compared to baseline But with considering the time- group interaction there was no significant difference between zinc and control group during this study.  There was no difference between lesion sizes and Leishmanial loads in the interventional and control groups, respectively. Conclusion: Sodium selenite and zinc sulphate at mentioned doses and duration of treatment did not show any treatment effect on cutaneous leishmaniasis caused by L. major in BALB/c mice. Increasing the dose of supplements and considering the follow up period after treatment can help more certain conclusion. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/141 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/141/140

Some of the recent studies revealed that hydatid cyst prevalence is decreasing gradually in Turkey. The aim of this study was to investigate the actual preva­lence of hydatidosis in an endemic region of Turkey, and to share our experiences in the medical and surgi­cal management of hydatidosis. Methods: Data were collected retrospectively from the records of 193 patients who had a diagnosis of hydatidosis, and admitted to Diyarbakir Education and Research Hospital. Imaging techniques, histology and serology were used for diagnosis. Results: From records of 772 cystic patients whose cysts were localized in the lung and liver, 193 (25%) of them were diagnosed with cyst hydatidosis. Lung hydatidosis was found statistically significant among these cases (Chi-square=24.88, P< 0.0001). Postoperative recurrence was detected in seven (3.62%) pa­tients. All postoperative recurrences were observed in the consequent three years period. Conclusion: The prevalence of hydatidosis is still high in southeast Turkey and not only in children but also in adult cases in our region lung hydatidosis is frequent corresponding with other organ hydatidosis. We also found that the most risky period in recurrence rates is the consequent post-operative three years. According to our experiences, transthoracic approach in lung hydatidosis, external drainage, and cystec­tomy in liver hydatidosis is safe and effective choices in surgical treatment.   https://ijpa.tums.ac.ir/index.php/ijpa/article/view/142 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/142/141

The object of this study was antigenic detection of G. duo­denalis in house­hold cats of Ahvaz district, South-West of Iran. Methods: The prevalence of G. duodenalis was determined in fecal samples by two techniques: centrifuga­tion-flotation and a commercial Giardia Antigen Test Kit (immunochromatography assay) in 150 household cats of different ages among referred cases to Veterinary Hospital of Ahvaz University from January 2008 to February 2010. Results: Five out of 150 fecal samples (3.33%) were positive for antigen of G. duodenalis by immunochromatography assay. The prevalence was significantly higher in young cats less than 6 months (15.79%) compared with adult cats 6 months - 3 years (1.37%) (P=0.027) and above 3 years (1.72%) (P=0.044). The infection had more prevalence in diarrheic cats (17.39%) com­pared with non-diarrheic cats (0.79%) and the difference was significant (P=0.02) as well. The prevalence was higher in male cats (3.41%) than females (3.23%) and in the season of autumn (6.06%), but the difference was not significant between the prevalence of infection relative to host gender and season (P>0.05). Microscopy examination on fecal samples showed that 2% of the studied cats were positive. Conclusion: The parasite antigen was present as a zoonotic infection in Ahvaz district, South-west of Iran. More sensitive techniques, such as immunochromatography assay, might yield more reli­able results, in the detection of low levels of Giardia in fecal samples of cats. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/143 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/143/142

There is preliminary evidence that these species may be the vectors of Babesia ovis in Iran. We carried out two experiments in Mashhad area, Khorasan Razavi Province to determine whether B. ovis could be transovarially transmitted by R. san­guineus and H. marginatum. Methods: In experiment 1, adults of laboratory reared H. marginatum and R.sanguineus were infected with B. ovis isolated from naturally infected sheep in Mashhad area by feeding the ticks on the sheep inoculated intravenously by infected blood samples. The inoculated sheep showed clinical signs with parasitaemia while the adult ticks were engorging on them. The engorged fe­males were collected and kept at 28°C and 85% relative humidity in incubator. Then, larval, nym­phal and adult stages derived from engorged females were used to infest the clean sheep. In experiment 2, two splenectomized sheep were infested only with the same adult ticks of two spe­cies. Results: Examination of smears and PCR of blood samples to detect of B. ovis in infested sheep in two experiments were negative. Conclusion: It seems that R. sanguineus and H. marginatum can not transovarially transmit B. ovis in sheep. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/144 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/144/143

Most cases of eosinophilia of parasitic origin, especially those with a tissue migration life cycles consists of human infections by helminth parasites. The aim of present study was to determine the parasitic causes of eosinophilia in patients in a major endemic area of human fascioliasis in Gilan Province, northern part of Iran. Methods: One hundred and fifty patients presenting with an elevated eosinophilia attending infec­tious disease clinics with or without clinical symptoms, were examined. After clinical his­tory evaluation and physical examination, coprological examinations were performed using the formalin-ether and the Kato-Katz techniques for detection of Fasciola sp. and intestinal parasites. Results: Forty two percent of patients were infected with S. stercoralis, nine (6%) were found to be infected with Fasciola sp. while only a single patient (0.7%) were infected by Ttrichostrongy­lus sp. Conclusion: Local clinicians in Gilan may consider eosinophilia as a suggestive indication for diagnosis of human fascioliasis, especially when microscopic stool and/or serological tests are negative. Based on the results, local physicians should consider S. stercoralis as the potential causes of eosinophilia in patients with elevated eosinophilia. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/145 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/145/144

The aim of the present study was to determine the effect of vitamin D3 on the multiplication of T. gondii in peritoneal macrophage of Balb/c mice and nitric oxide production by macrophages.  Methods: According to usage of vitamin D3 (one dose or seven doses) and INFγ in vitro and in vivo, this study was divided into four experiments. In all experiments, the macrophages were col­lected from peritoneum and cultured in RPMI-1640. Then the supernatants were collected after 24 h and their nitric oxide was measure. After 96 h, the macrophages were collected and stained and the number of tachyzoites was measured.  Results: The first experiment (the mice were infected with tachyzoites and after 2 h, got one dosevita­min D3 intraperitonealy) showed the best results. The mean of tachyzoites per macrophages was 2.37, and mean ± SD of nitric oxide was 187.8 ± 9. Discussion: High-level production of nitric oxide may be related to the only one injection of vita­min D3. The injection in long time might suppress the immune system. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/146 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/146/145

The aim of the article was to research the relations between para­sitic appendicitis and literacy ratio in population. Methods: Cases of parasitic appendicitis resulting in surgery performed at Buca Seyfi Demirsoy Large State Hospital Surgery Clinic between 2002 and 2009 were retrospectively reviewed and classified accord­ing to age, sex, type of parasite, morbidity, and mortality. Studies conducted in different regions of Turkey as well as in other countries were reviewed to determine if there was a relationship between para­sitic appendicitis and literacy. Results: Of the 1,969 appendectomy cases reviewed, nine were classified as parasitic appendicitis (0.45%). Enterobius vermicularis was observed in seven cases and Taenia spp. in two. The average age was 26.4 yr. No morbidity or mortality was found. Conclusion: The data were compared with a retrospective review of studies conducted in the same regions and a decrease in the rate of parasitic appendicitis was observed during the period between the two re­views. It was determined that a low literacy rate was associated with an increase in the incidence of para­sitic appendicitis. Observations made between different countries also produced similar results. In coun­tries where the incidence of parasitic appendiciticis was greater than 1.5%, the literacy rate was less than 88%. To avoid appendectomy resulting from parasites, it is important to increase education and literacy. In some areas, individuals with appendicitis undergo surgery due to a lack of education or poor literacy. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/147 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/147/146
