Mycotoxins have the potential to reduce the quality of crops and pose health risks to both humans and animals. This can result in reduced animal production and substantial economic consequences on a global scale. Extensive research has been carried out to investigate the high incidence of contamination in grains by <i>Fusarium</i> fungi. In this study, 80 samples of maize from silos of dairy farms in Fars province, Iran were collected and examined for fungal contamination by <i>Fusarium</i> and potential production of DON and FUM. For this purpose, identification using specific primers for different genes was carried out by polymerase chain reaction test and gel electrophoresis with agarose (1%). Among different counties, the silos in Kharameh with 47.05% and Jahrom with 46.15% had the highest contamination rates, and the lowest contamination rate belonged to Kazeroon with 27.27%. Out of the 30 positive samples contaminated by <i>Fusarium</i>, 21 produced FUM, 4 produced DON, and 5 produced both toxins. <i>Fusarium</i> species that contaminated the maize samples were also identified, including 13, 10, and 7 samples contaminated by <i>F. proliferatum</i>, <i>F. verticillioides</i>, and <i>F. graminearum</i>, respectively.

This review study aimed to present a comprehensive analysis of the prevalence of <i>T. gallinae</i> in birds of Iran, along with an exploration of its associated pathological findings. Through an extensive search of published studies, scientific databases, and relevant literature, we identified several studies conducted in Iran that focused on the prevalence of <i>T. gallinae</i> in different bird populations and their pathological effect. These studies utilized a variety of techniques, including direct microscopic examination, culture methods, and molecular tools to detect and identify the presence of this parasite. This review study indicates that <i>T. gallinae</i> infections are prevalent among various bird species in Iran, including Domestic pigeons, Zebra Finches, and Turkey. The reported prevalence rates showed significant differences among various regions and bird species, ranging from as low as 2.5% in zebra finches to as high as 70% in pigeons. The clinical signs of infected birds varied from no clinical signs to visible yellowish-white masses of caseous necrotic material, hyperplasia of mucous cells, and significant congestion of the lung. These findings underline the importance of <i>T. gallinae</i> as a significant pathogen affecting avian populations in Iran. Using at least two techniques, such as culture or PCR, in addition to direct smear is recommended for better diagnosis of infection.

This study focused on modeling the time series data of scorpion stings, specifically in Shoushtar City, from 2017 to 2022. Our objective was to investigate the presence of seasonality and long-term trends in the incidence of scorpion stings by utilizing advanced analytical techniques, such as the Autoregressive Integrated Moving Average (ARIMA) model. We applied the seasonal ARIMA model to fit a univariate time series of scorpion sting incidence. This study revealed a significant seasonal trend and an overall increase and decrease in scorpion sting cases during the study period. The best-fitting model for the available data was a seasonal ARIMA model in the form of ARIMA(0,0,1)(1,1,1)12. This model can forecast the frequency of scorpion sting cases in Southwestern Iran over the next two years. As a result, time series analysis can provide valuable insights into the patterns and trends of scorpion sting incidents, allowing for better planning and allocation of healthcare resources.
