Distribution of Toxocara Vitulorum in Cattle of Ağrı Region
(Galenos Publishing House, 2023) Afshar, M.T.; Aydemir, S.; Yılmaz, H.; Yıldız, R.; Barlık, F.; Yasul, M.
Objective: Parasitizing in the small intestines of cattle, buffalo and bison, Toxocara vitulorum is seen in countries with humid tropical and subtropical climates, including Türkiye. Adult parasites can cause digestive disorders such as loss of appetite, weakness, diarrhea or constipation, and sometimes death, especially in calves. This study was planned to investigate the distribution of T. vitulorum in cattle of the Ağrı region. Methods: In this study, stool samples of the size of a walnut were taken from the rectum of 200 calves 0-6 months old and 200 cattle older than 1 year in the province of Ağrı and its districts, and the preparations were prepared using the saturated zinc sulfate flotation method and the preparations were examined under a light microscope. Results: T. vitulorum eggs were detected in 70 (35%) of 200 calves aged 0-6 months and 21 (10.5%) of 200 cattle over one year old. The difference in positivity between cattle over one year old and calves was statistically significant (p=0.001). With fecal examination ın 22 of the calves (11%), Trichostrongylidae spp. eggs were detected. Conclusion: It was determined that the prevalence of T. vitulorum in calves was high in Diyadin, Eleşkirt, Doğubayazıt, Hamur, Taşlıçay, Tutak and Patnos districts of Ağrı province. We believe that larger-scale studies should be conducted on the spread of this parasite, which causes significant low yields in cattle breeding. © Telif hakkı 2023 Türkiye Parazitoloji Derneği-Makale metnine.
Gastrointestinal Helminths and Zoonotic Importance Detected in Stray Dogs in Ağrı Province and Districts
(Galenos Publishing House, 2022) Afshar, M.T.; Yıldız, R.; Cengiz, Z.T.; Aydemir, S.; Şahin, M.
Objective: This study aimed to investigate the frequency of gastrointestinal helminth parasites in stray dogs in Ağrı province and its districts and to reveal the zoonotic importance of these parasites. Methods: Fecal samples were collected from a total of 279 stray dogs in the center of Ağrı and the districts of Diyadin, Doğubayazıt, Eleşkirt, Hamur, Patnos, Taşlıçay, and Tutak. After macroscopic examination of the stool samples, they were examined microscopically by the native and multiplexing (Fulleborn flotation and Benedek sedimentation) methods. Results: Helminth eggs belonging to one or more species were detected in 80 (28.7%) of the 279 stool samples examined. In total, 31 (11.1%) T. canis, 24 (8.6%) T. leonina, 17 (6.1%) Taenia spp., 15 (5.4%) Capillaria spp., 10 (3.6%) Alaria spp., 5 (1.8%) T. vulpis, and 3 (1.1%) A. caninum egg were detected in the stool samples Conclusion: In this study, which was performed for the first time in Ağrı, it was revealed that stray dogs in Ağrı province and its districts were infected with helminths, which may consequently affect human health significantly. Therefore, necessary precautions should be taken to preserve the health of both humans and dogs. © 2022 Turkish Society for Parasitology.
The Impact of Covid-19 Pandemic on Intestinal Parasite Frequency: a Retrospective Study
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Aydemir, S.; Afshar, M.T.; Şahin, M.; Cengiz, Z.T.; Elasan, S.; Barlık, F.; Yılmaz, H.
During the COVID-19 pandemic, countries have closed their borders, banned travel, and restricted human mobility even outdoors in order to control the infection. It is not known whether the measures taken to control the pandemic in Türkiye affect the prevalence of intestinal parasitic infections. This study was conducted to evaluate the effect of the COVID-19 pandemic on the prevalance of intestinal parasites. In the study, the parasitological data of 18,204 patients who applied to Dursun Odabaş Medical Center between June 2018 and December 2021 and whose stool samples were sent to the parasitology laboratory were evaluated retrospectively. Intestinal parasites were detected in 1214(9.89%) of 12270 patients in the pre-COVID-19 period and in 866 (14.59%) of 5934 patients during the COVID-19 period. In the statistical evaluation, it was observed that there was a significant difference between the positivity rate in the pre-COVID-19 period and the positivity rate in the COVID-19 period. On species basis, there was a decrease in the rates of pathogenic parasites G. intestinalis and E. histolytica, but an increase in the rate of B. hominis, which is discussed to be pathogenic. It has been concluded that the decrease in the rate of pathogenic parasites transmitted by fecal-oral route is since the general hygiene rules and the decrease in human-to-human contact are effective in the COVID-19 period. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi.

Prevalence of Fascioliasis in Slaughtered Cattle in Ağrı Province
(Galenos Publishing House, 2023) Şahin, M.; Afshar, M.T.; Yıldız, R.; Aydemir, S.
Objective: In this study, it was aimed to reveal the frequency of fascioliasis in cattle slaughtered in the slaughterhouses of Ağrı province. Methods: The study was carried out on 230 cattle. The presence of Fasciola hepatica eggs in stool and bile fluid samples taken from each cattle was investigated by sedimentation-zinc sulfate flotation method, and the presence of adult parasites in the liver and bile ducts by postmortem examination. Results: The study was conducted on 230 cattle samples. Fasciola spp. eggs were observed in 43 (18.7%) of the stools examined. As a result of the postmortem examination of the liver and gall bladder, F. hepatica adults were found in 52 (22.6%) cattle. All cattle positive in stool examination were also positive in liver and gallbladder examination. Fasciola gigantica adults were not detected in any of the cattle, and there was no statistically significant difference in terms of gender and race. Conclusion: In this study conducted on cattle in the Ağrı region, F. hepatica was found to be significantly common. The data obtained show that in order to prevent economic losses in animal husbandry, which is an important source of livelihood of the local people, effective prevention and control programs should be planned and implemented, and both sheep and cattle breeders should be made aware of the prevention of this infection. © 2023, Galenos Publishing House.
