    Abstract Microsporidia spp. are recognized emerging zoonotic microorganisms in immunocompromised and immunocompetent populations. Therefore, we conducted a study to investigate the occurrence, sociodemographic and risk factors of microsporidia spp. infection using microscopic and molecular techniques in children with diarrhea in Jahrom city (Fars province, southern Iran). Stool samples were gathered from 395 children aged ≤ 14 years between January 2017 and January 2018. Next, a questionnaire includes the age, sex, living area, immune system status, breast milk consumption, contact with animals, and type of water source was completed for all children. For microscopic assessment, modified acid-fast trichrome staining was applied for detection of microsporidia spores. Furthermore, DNA extraction and PCR were accomplished for all samples. A total of 15 (3.79%; 95% confidence interval [CI] 2.14-6.19) and 8 (2.02%; 95% CI 0.88-3.95) samples were positive for microsporidia infection by microscopic and molecular techniques, respectively. Although none of the sociodemographic and risk factors were significant (

Although none of the sociodemographic and risk factors were significant (p value > 0.05), the prevalence of this infection was higher in some variables (e.g., rurality, contact with animals and well water consumption). Three random samples were sequenced that all isolates belonged to Enterocytozoon bieneusi. Cognizance of microsporidia occurrence, risk factors, and disease disorders for the health specialists, physicians, children’s families are important for appropriately control the infection.

    Abstract Aim: Toxoplasma gondii has a clinical and veterinary importance as it is known to cause congenital disease and abortion both in humans and livestock. Since the contaminated lamb is one of the sources of human infection, this study was performed to determine the prevalence of T. gondii in sheep in south of Iran.
    Materials and methods: Sera and tissue samples (diaphragm and heart) were collected from 370 sheep from slaughterhouse of Jahrom. The samples were taken from both sexes and from 6 to 60 months age. Specific immunoglobulin G antibodies to T. gondii were examined with enzyme-linked immunosorbent assay, and B1 gene nested-polymerase chain reaction detection was done to survey the tissue samples.
    Results: The total prevalence of Toxoplasma infection among sheep was found to be 35.94% and 34.32% based on serological and molecular method, respectively. According to serologic and molecular findings, the females were more positive than males for Toxoplasma; maximum frequency of positive samples was observed in 24-36 months and the positive samples had been collected more in spring than in summer, but no statistical correlation was observed between prevalence rate and the age and sex of animals or season of sampling.
    Conclusion: T. gondii is widely distributed in sheep in Jahrom with a rate comparable with other parts of Iran and the world. It suggested a widespread exposure of sheep in this region to T. gondii. Thus, consumption of undercooked or raw meat presents the transmission risk of the parasite and this might be considered as an important public health problem, mainly for high-risk groups such as the pregnant and the immunodeficient.

    Abstract Aim: This study was performed to determine the genetic diversity of Toxoplasma gondii in sheep using nested-polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in Southern Iran. Materials and Methods: The tissue samples of diaphragm and heart from 125 sheep were collected from the main slaughterhouses of Jahrom district in South of Fars province, Iran, between Aprils and June 2013. The DNA were extracted and analyzed by nested-PCR using specific primers for SAG2 and GRA6 loci. RFLP was used to classify strains into one of the three major lineages of T. gondii. Results: T. gondii Type I was predominant in this area. The data obtained from both loci demonstrated that the frequency of each genotype was 72% Type I, 2.4% Type III, 7.2% mixed Type I and II, 16.8% mixed Type I and III, 0.8% mixed Type II and III, and 0.8% mixed Type I, II and III. Conclusion: Although the previously published data indicated that Type II is the predominant T. gondii genotype in sheep in the other parts of the world, this study showed that genotype I is the dominant genotype of T. gondii in the southern Iran; however, other genotypes were detected. High diversity of T. gondii genotypes including mix genotypes in lambs is of importance for the public health. These studies depict a new mapping of T. gondii genotypes pattern which could be very helpful in toxoplasmosis control and prevention.

    Abstract Introduction: Depression is a mental disorder that highly associated with immune system. Therefore, this study compares the serum concentrations of IL-21, IL-17, and transforming growth factor β (TGF-β) between patients with major depressive disorder and healthy controls.
    Methods: Blood samples were collected from 41 patients with major depressive disorder and 40 healthy age-matched controls with no history of malignancies or autoimmune disorders. The subjects were interviewed face to face according to DSM-IV diagnostic criteria. Depression score was measured using completed Beck Depression Inventory in both groups. The serum concentrations of IL-21, IL-17, and TGF-β were assessed using ELISA.
    Results: The mean score of Beck Depression score in the patient and control groups was 35.4±5.5 and 11.1±2.3. IL-17 serum concentrations in the patients and the control group were 10.03±0.6 and 7.6±0.6 pg/mL, respectively (P=0.0002). TGF-β level in the patients group was significantly higher than compare to the control group; 336.7±20.19 vs. 174.8±27.20 pg/mL, (P<0.0001). However, the level of IL-21 was not statistically different between the two groups 84.30±4.57 vs. 84.12±4.15 pg/mL (P>0.05).
    Conclusion: Considering pro-inflammatory cytokines, current results support the association of inflammatory response and depressive disorder. So, it seems that pro-inflammatory factors profile can be used as indicator in following of depression progress and its treatment impacts.

    Abstract Patients with beta-thalassaemia major and asplenia have an increased risk of encapsulated bacterial infections. The aim of this study was to determine the Haemophilus influenza type b (Hib) antibody concentrations in beta-thalassaemia patients with or without spleens. The Hib antibody concentrations were investigated in 850 patients with thalassaemia major, of whom 437 had undergone splenectomy. Hib antibody levels equal or greater than 1.0 μg mL(-1) were classified as long-term protection, those between 0.15 and less than 1.0 μg mL(-1) as short-term protection and those less than 0.15 μg mL(-1) as no protection. The mean Hib antibody level was lower in asplenic subjects than in non splenectomised subjects (0.39 ± 0.5 vs. 1.08 ± 0.55 μg mL(-1), p < 0.001). The protective antibody level prevalence in asplenic patients was significantly lower than that in patients with spleens (32.3% vs. 85.7%, p < 0.001). Protection against Hib decreased as the time interval after splenectomy increased from 57.2% at a less than 60 months interval to 10.8% at a greater than 120 months interval (p = 0.001). Nearly 30% of the 437 splenectomised subjects had long-term protection against Hib, whereas 64.4% of the 413 non splenectomised subjects had long-term protection (p < 0.001). Asplenic subjects had lower Hib antibody levels than non splenectomised subjects. Additionally, the antibody levels decreased as the time interval increased after splenectomy. A Hib vaccine recommendation for splenectomised thalassaemia major seems essential.

    Abstract Background: Type 1 diabetes (T1D) is thought to involve chronic inflammation, which is manifested by the activation and expression of different inflammatory mediators. Th1- and Th17-associated cytokines are factors that have been shown to exert profound pro-inflammatory activities and have been implicated in the pathogenesis of T1D in mice and humans.
    Objectives: Therefore, the aim of this case control study was to determine the serum level of IL-17, IL-21, IL-27, transforming growth factor beta (TGF-β), and IFN-γ and their reciprocal relationship in Iranian T1D patients.
    Patients and methods: Blood samples were collected from 48 T1D patients and 49 healthy individuals with no history of malignancies or autoimmune disorders based on simple sampling. The serum levels of IL-17, IL-21, IL-27, TGF-β, and IFN-γ were measured by the enzyme linked immunosorbent assay (ELISA).
    Results: The serum levels of IL-17 and IL-21 were significantly higher in T1D patients compared to the healthy individuals (p = 0.005 and 0.01, respectively), but interestingly, the opposite was the case for IL-27 (p < 0.0001). However, there were no significant differences in TGF-β and IFN-γ between both groups. In addition, IL-17/IFN-γ and IL-17/IL-27 ratios were higher in patients compared to the control group.
    Conclusions: Our results indicated dominant Th17-associated IL-17, suggesting a shift from the Treg and Th1 phenotypes toward the Th17 phenotype. Therefore, it can promote inflammation in β cells in T1D. In addition, it suggests the role of Th17 and Th17/Th1 ratios as a potential contributor to β cells destruction and the Th17/Th1 response ratio may provide a novel biomarker for rapid T1D diagnosis before the destruction of β cells and progression of the disease to the clinical end stages.
