        Viral gastroenteritis is one of the most common ailments in all age groups acrosdxdxs the globe, and more than 700 million cases of diarrhea occur in children under five years of age. Rotavirus, norovirus, adenovirus and astrovirus are important causes of acute viral gastroenteritis. Co-infection studies have been conducted in Iran in the past, but these studies were limited and heterogeneous. The purpose of this study is to investigate the frequency of co-infection of rotavirus with astrovirus and adenovirus and to investigate clinical parameters such as fever, duration and severity of diarrhea in positive cases of co-infection. In this article, the co-infection of rotavirus with adenovirus and astrovirus among 28 rotavirus positive samples collected from children under five years of age with gastroenteritis was investigated by molecular method. The frequency of simultaneous rotavirus-adenovirus infection was two and rotavirus-astrovirus infection was observed in four children. In addition to this, the documentation available in the patients' files and its relationship with the objectives of the current study show that the positive results of simultaneous infection only increased the duration of diarrhea and did not cause other specific symptoms such as duration of fever and severity of diarrhea. In this study, the sample size was low, but according to the results, it can be said that the current study shows the importance of simultaneous diagnosis of viral diarrhea factors in order to predict the duration of diarrhea and the possibility of other clinical symptoms.

        Nowadays, due to the existence of different occupations, it is not possible to cook food for all the people of a society, and most of the people have turned to using ready-made foods, which, in addition to all its advantages, can be a source of They are important bacterial contaminations that cause the spread of gastroenteritis. In this regard, the aim of this study is to investigate the prevalence of Arcobacter, Pseudomonas, Campylobacter and Bacillus cereus in sandwiches offered in Qom city and the antibiotic resistance of the isolates. 120 samples, including 30 samples of samosas, salads, traditional chicken nuggets, traditional hamburgers from the supply centers of Qom city, were randomly separated and transported to the food hygiene laboratory of Shahrekord Azad University along with ice flasks to prevent secondary contamination. The standards were evaluated. The results showed that Arcobacter 28.83%, Pseudomonas 16.65%, Bacillus cereus 23.35% and Campylobacter 14.75% were the highest and lowest contamination rates for Arcobacter and Campylobacter respectively. The highest level of resistance to antibiotics was related to Bacillus cereus with 78.56% and the lowest resistance was related to Campylobacter with 53.7%. Therefore, it is recommended to reduce the consumption of street food to a minimum, and in case of gastroenteritis caused by food contamination, the use of antibiotics should also be minimized.
