Keywords: Acute Gastroenteritis, Parasite, Rotavirus, Enteric Adenovirus

Objective: In our study, stool samples of patients presenting with acute gastroenteritis (AGE) were retrospectively evaluated according to the seasons and demographic characteristics of the patients in terms of rotavirus, enteric adenovirus and parasitic agents.

Method: Stool samples of patients aged within 0-80 years who were admitted to our hospital with AGE complaints between August 1, 2018 and December 1, 2021 were evaluated for the presence of rotavirus, enteric adenovirus and parasitic agents. Detection of rotavirus and enteric adenovirus in samples was carried out using the MICROCULT (rotavirus/adenovirus Combo, Biotech, China), which is an immunochromatographic kit. Parasitic agents were initially investigated with microscopy, using the nativ-Lugol method; those with suspected protozoa were further examined using Kinyoun’s and trichrome staining methods.

Results: Of the 21,587 patients admitted to our hospital with AGE complaints, 63.74% were children and 36.25% were adults. According to the incidence of the factors, rotavirus was detected in 1,124 (9.56%), Entamoeba histolytica/dispar 520 (2.44%) and enteric adenovirus was detected in 236 (2%) patients, respectively. Rotavirus was detected in 740 (13.86%) patients between the ages of 2-4, and in 3 (9.37%) patients between the ages of 29-38, among adult patients, among pediatric patients. Entamoeba histolytica/dispar was detected in 70 (6.15%) patients aged 9-12 years and in 30 (3.62%) patients aged 59-68 years in adults. According to the seasons, rotavirus positivity in adults was detected most often in 2 (8.33%) patients in the spring season, and in children in 256 (13.71%) patients in the winter season. Entamoeba histolytica/dispar, the most common parasitic agent in microscopic examinations, was detected most often in spring, in 46 (2.93%) adults and 96 (3.88%) children.

Conclusion: Rotavirus, the leading agent in our study that targeted the causative agents of AGE, was detected in children aged between 2-4 years and in adults aged between 29-38 years; according to the seasons, children were most often detected in winter and adults in spring. Among the parasitic factors, Entamoeba histolytica/dispar, the most common parasitic agent in our study, was detected in children aged within 9-12 years, in adults between 59-68 years; according to the seasons, it was detected in the spring season in both adults and children. It was concluded that the microbiological variety of tests for the causative agent in patients admitted to the hospital with AGE complaints can be useful for the diagnosis and treatment of patients with such complaints with proper planning and data obtained in accordance with the laboratory’s capabilities.
