Background And Objectives: Q fever is a zoonotic disease and farm animals serve as the main reservoir of the disease. The aim of this study was to evaluate the seroprevalence of Q fever in sheep, in Lorestan province in western Iran.
Materials And Methods: In this cross-sectional study, 330 blood samples were collected from sheep, from each county in Lorestan province. The samples were tested by ELISA for the presence of immunoglobulin (IgG) against .
Results: Among the samples tested, 45 samples (13.64%) were seropositive. Of 35 studied herds, 21 (60%) had a history of infection. In terms of number of positive samples, there was no significant difference between the three geographical regions (central, west and east) (p=0.687). There was no statistically significant difference between age groups (p =0.604). Gender also had no effect on infection rates, in female and male sheep (p =0.814). No significant difference was observed between the number of lactation and positive serology (p =0.376). The rate of infection with Q fever and abortion also had no statistically significant difference (p =0.152).
Conclusion: The findings of this study showed that sheep in Lorestan were infected by Q fever and the cycle of disease transmission had been established between animals and ticks.

Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) are known as the most common blood-borne viral infections worldwide. Individuals referring to drop-in centers (DICs) are considered high-risk people exposed to infection with blood-borne viruses. The purpose of this study was to investigate the prevalence of HIV, HBV, and HCV infections among women referred to DICs in Lorestan Province, western Iran.

Human platelet antigens (HPAs) play a clinically significant role in alloimmunization and the development of immune-mediated disorders such as immune thrombocytopenia (ITP), fetal and neonatal alloimmune thrombocytopenia (FNAIT), and post-transfusion purpura (PTP). Understanding the genetic profiles of HPAs is critical for preventing and treating these conditions. Given the limitations of serological methods in determining HPA genotypes, this study aims to investigate the association between the genotypes of HPA1, HPA2, HPA3, HPA4, and HPA15 antigens and autoimmune thrombocytopenia in Lorestan Province, utilizing the PCR-SSP method.

Introduction: Microbial contamination in food products such as pastries, poses a significant public health concern due to the potential risks of foodborne infection and outbreak, Therefore, to prevent these infections, it is essential to investigate the frequency and extent of microbial contamination as well as the level of drug resistance in pastries. Due to this issue, our study aimed to assess the microbial diversity and the drug susceptibility patterns of microbial pollutants in pastry shops in Markazi province, Iran.
Methods: The study involved collecting 120 pastry samples from 30 pastry shops in Markazi province, Iran.

Moreover, since these checklist were published, several ladybird species have been added to the Iranian fauna and several previously reported have been excluded. We therefore compiled an updated checklist of Coccinellidae found in Iran and its individual provinces based on available literature and previously unpublished records.
