(Galenos Publishing House, 2022) Karakuş, İ.; Cengiz, Z.T.; Ekici, A.
Objective: This study aimed to determine the frequency of intestinal parasites in children who were presented to health centers with a complaint of diarrhea and to reveal the importance of these parasites. Methods: The study was conducted on children within the age range of 1-16 who were presented to Iğdır State Hospital and Private Bulut Hospital between 2020 February-April 2020 with a complaint of diarrhea. A total of 300 children comprising 141 girls and 159 boys were enrolled in the study. The control group was composed of 100 children (girls=50, boys=50) without any chronic disease and diarrhea. Stool samples were evaluated by the native-Lugol method and the modified acid-fast staining method. Results: Intestinal parasite positivity was found in 105 (35%) out of the 300 children in the patient group and in 17 (17%) out of the 100 children in the control group. In terms of parasitic positivity, a statistically significant difference was found between children with diarrhea and the healthy control group (p=0.001). Blastocystis hominis (13%), Cryptosporidium spp. (3%), and Giardia intestinalis (2%) were found in the patient group. Intestinal parasitic positivity was found in 30.2% and 40.4% of the boys and girls in the patient group, respectively, whereas it was found in 14% and 20% of the boys and girls in the control group, respectively. When evaluated statistically according to gender, a significant difference (comparison for boys: p=0.008; comparison for girls: p=0.004) was noted between the patient group and control group for each gender. In terms of the relationship between the frequency of parasites and some living conditions of the patients, a statistically significant relationship was found in the comparison of “whether or not livestock” (p=0.004) and “whether there is a sewerage network” (p=0.002). Additionally, a significant difference was found between parasitic positivity and abdominal pain (p=0.008) and nausea (p=0.003). Conclusion: The present study concludes that children with clinical symptoms, such as diarrhea, abdominal pain, and nausea, should be evaluated for intestinal parasites. Furthermore, it has been understood that intestinal parasites remain an important health problem among the pediatric cohort. © 2022 Turkish Society for Parasitology.

(Yuzuncu Yil Universitesi Tip Fakultesi, 2025) Şahin, M.; Cengiz, Z.T.; Halidi, A.G.; Aydemir, S.; Ekici, A.
This study aims to determine whether patients with diabetes are at risk for intestinal parasites. The study included 200 diabetics and 150 healthy i ndividuals without any chronic disease. Data such as age, gender, diagnosis, and patient laboratory test results were obtained from the hospital automation system. Stool samples were examined by native-Lugol, concentration, modified acid-fast, and trichrome staining methods. Intestinal parasites were found in 27.5% of the diabetic patients and 14% in the control group; the difference between the two groups was statistically significant (p=0.001). Out of 200 patients, Blastocystis hominis was found in 44 (22%), Cryptosporidium spp. in one (0.5%), B. hominis and Entamoeba coli in five (2.5%), Giardia intestinalis in two (1%), B. hominis and G. intestinalis in one (0.5%), Taenia spp. in one (0.5%) and Chilomastix mesnili in one (0.5%). In the diabetic patient group, statistically significant differences were found between age (p=0.043), duration of diabetes (p=0.006), fasting blood glucose (p=0.028) and HbA1c value (p=0.01) and presence of intestinal parasites. No statistically significant differences were found between place of residence, biochemical values such as cholesterol and LDL, use of insulin and antidiabetic agents, presence of another disease such as hypertension, COPD, neuropathy, nephropathy and intestinal parasite positivity. Patients with diabetes can be considered a risk group in terms of intestinal parasite infections. Furthermore, individuals with a history of diabetes of more than 10 years and poor glycemic control are at a higher risk for intestinal parasites. © 2025, Yuzuncu Yil Universitesi Tip Fakultesi.

(Galenos Publishing House, 2022) Bozkurt, Y.T.; Cengiz, Z.T.; Ekici, A.; Yılmaz, H.
Objective: This study was conducted to investigate the frequency of intestinal parasites in substance abusers and to reveal its significance. Methods: The study was conducted in Van Yüzüncü Yıl University Medical Faculty Parasitology Research Laboratory and University of Health Sciences Turkey Van Training and Research Hospital between May 2019 and February 2020. The patient group included 150 patients with substance abuse who applied to the Alcohol and Drug Addicted Treatment Center of University of Health Sciences Turkey Van Training and Research Hospital, while the control group included 75 patients who had no chronic illness and did not use cigarettes, alcohol, or drugs. Stool samples were examined using native-Lugol and modified acid-fast staining methods. Results: In this study, one or more intestinal parasites were found in 21.3% of 150 patients who applied to the internal medicine outpatient clinic and had no chronic illness and did not use cigarettes, alcohol, or drugs. There was a statistically significant difference between the two groups in terms of the parasite frequency (p=0.03). In the patient group, Giardia intestinalis was detected in 7.3% (p=0.02), Blastocystis hominis in 6.7%, and Hymenolepis nana in 0.7%. Considering the frequency of parasites in terms of age groups, intestinal parasites were found at a higher rate in the 35 and younger age group (23.8%) than in the 36 and older age group (17.2%). Intestinal parasite positivity was found at the highest rate (23.8%) in those using methamphetamine. Constipation (79.3%) was the most prevalent in parasite-positive substance abusers, followed by diarrhea (23%). Conclusion: This study contributed to the literature by determining the frequency of intestinal parasites in people addicted to substance, and it was revealed that intestinal parasite infections are a negative consequence of substance addiction. Conclusively,our findings revealed that intestinal parasites should be considered in substance abusers. Also, more detailed studies involving more individuals should be conducted to obtain information about intestinal parasite infections. © 2022 Turkish Society for Parasitology.

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.

The Importance of Antioxidant Enzymes and Oxidative Stress in Human Fascioliasis
(Galenos Publishing House, 2023) Cengiz, Z.T.; Yılmaz, H.; Beyhan, Y.E.; Ekici, A.; Çiçek, M.; Aydemir, S.
Objective: The aim of this study was to determine the levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), and malondialdehyde (MDA) in the patients infected with Fasciola hepatica and establish whether these parameters differ among the patients with fascioliasis. Methods: The patient group consisted of 140 individuals with F. hepatica seropositive; the control group consisted of 140 healthy individuals who tested negative for this parasite and had no other diseases. The patient group consisted of individuals with no chronic diseases other than fascioliasis; in both the patient and the control groups, the subjects had no unhealthy habits such as smoking and alcohol consumption, etc. The blood samples taken to diagnose fascioliasis were evaluated by the ELISA method. The samples were studied according to the kit procedures for SOD, CAT, GPx and MDA markers. Results: In this study, 43.6% of 140 individuals in the patient group infected with F. hepatica had CAT (p=0.001), 35% had GPx (p=0.001), 12.9% had SOD (p=0.002), 90.7% had MDA (p=0.001). There was found a statistically significant difference between the patient and the control group in terms of the positivity of these four parameters. Conclusion: As a result, a statistically significant relationship was found between the increase in the SOD, GPx, CAT, and MDA levels and fascioliasis. The high rate of MDA revealed that oxidative stress occurred in patients with fascioliasis, resulting in an increased activity of SOD, GPx, and CAT. © 2023, Galenos Publishing House.

(Galenos Publishing House, 2023) Yürektürk, Ş.; Yılmaz, H.; Cengiz, Z.T.
Objective: The aim of this study was to determine the seroprevalence of Toxoplasma gondii in hemodialysis (HD) patients and to reveal the importance of toxoplasmosis as a risk factor in these patients. Methods: The study was carried out between 26.12.2013 and 01.01.2016 at Van Yüzüncü University Dursun Odabaş the Medical Center on patients with chronic renal failure who entered HD. As the patient group in the study, 150 patients with chronic renal failure who underwent HD; as the control group, 50 people without any known chronic disease and who did not receive any immunosuppressive therapy were included. The ELISA method was used to determine anti-T. gondii IgG and IgM antibody levels. A questionnaire including risk factors that may cause the transmission of T. gondii was applied to the patient and control groups. Results: In the study, 89 out of total 150 HD patients (59.3%) were found anti-T. gondii IgG antibody seropositive and 4 were (2.7%) anti-T. gondii IgM antibody seropositive. Fourteen of 50 healthy individuals in the group (28%) were anti-T. gondii IgG antibody positive, while none in this group was anti-T. gondii IgM antibody positive. Statistical analysis demonstrated there were separate significant correlations between both anti-T. gondii IgG (p<0.01) and anti-T. gondii IgM antibody (p<0.05) frequencies with chronic renal failure. While there were no statistically significant differences in the prevalence of anti-T. gondii IgG antibody identification based on gender and age groups, there were significant differences between the prevalence of anti-T. gondii IgM antibody based on both gender (p<0.05) and age groups (p<0.05). Some living conditions and habits of the patient group were evaluated statistically, and a significant correlation (p<0.05) was found between eating only raw meatballs and toxoplasmosis seropositivity. Conclusion: As a result, it was understood that the physicians who monitor of HD patients should assess toxoplasmosis among the risk factors. © 2023 Turkish Society for Parasitology-Available online at www.turkiyeparazitolderg.org.
A Nasopharyngeal Human Infestation Caused by Linguatula Serrata Nymphs in Van Province: a Case Report
(2011) Yilmaz, H.; Cengiz, Z.T.; Ciçek, M.; Dülger, A.C.
The reason for the presentation of this case is that Linguatula serrata, a parasite rarely encountered in humans, was found in a patient in Van province. The patient, who was 26 years old, lived in Erciş a town in Van province, East Turkey. She was admitted to the Outpatient Clinic of Infectious Diseases of Erciş Government Hospital with a complaint of coughing a few worms about 4 cm long from the oral cavity, and also sore throat, partial voice loss and vomiting. The polyclinic doctor suspected that the worm was a parasite but he could not make a diagnosis, and the patient was referred to Health Research and Training Hospital, Yüzüncü Yil University. The parasite was examined in the Parasitology Laboratory and it was observed that this parasite was the nymph of L. serrata whose mouth was surrounded with four hooks and had approximately 90 body segments with small hooks. No medical treatment was given to the patient except that gargling with saline solution was recommended. As a result, we think that physicians should consider L. serrata infestation in patients applying to health foundations with complaints such as pharyngitis accompanied by pharyngeal pain, coughing, sneezing and vomiting.

(Galenos Publishing House, 2019) Cengiz, Z.T.; Yılmaz, H.; Beyhan, Y.E.; Yakan, Ü.; Ekici, A.
The objective of the present study is to present a patient with oral myiasis caused by Calliphoridae larvae. The patient was a 63-year-old male who was transferred from Van Closed Prison to Yüzüncü Yıl University, Faculty of Medicine Research and Application Hospital. Five alive larvae localized in different points of gingival region were observed during routine oral cleaning. These larvae belonged to Calliphoridae family. As a result, medical staff should be informed about this infestation and this parasite should be kept in mind especially in risky group of patients and necessary controls should be conducted. © 2019 Turkish Society for Parasitology.
Sheep Trichostrongylidosis in Van Province
(2009) Cengiz, Z.T.; Deǧer, M.S.
This study was performed in the Van Municipality Slaughterhouse from January to December 2001. Abomasums and small intestines from a total of 104 sheep were transported to the parasitology laboratory of the Veterinary Faculty of Yüzüncü Yil University for parasitological examination. The abomasums and small intestines of the animals were opened with appropriate technique in the laboratory, and male nematodes were collected from the contents of the abomasums and small intestines using a sampling method, and then these parasites were identified. Gastrointestinal nematodes were encountered in 87.5% out of 104 sheep. Marshallagia marshalli (85%), Teladorsagia circumcincta (75%), Nematodirus oiratianus (75%), N. spathiger (65%), Haemonchus contortus (40%), Tel. occidentalis (36%), Trichostrongylus axei (33%), N. abnormalis (19%) and T. probolurus (19%), Tel. davtiani (15%), Tel. trifurcate (10%), and Camelostrongylus mentulatus (1%) were detected. Among the parasites, the species encountered most often were Tel. circumcincta (45.23%) in abomasums and N.oiratianus (65.73%) in small intestines. The highest rate of parasites in both abomasums and small intestines occurred in August, September and October. It was found that the young animals have a parasite density higher than the adults and the females have parasite density higher than the males.
The Significance of Opportunistic Parasitosis and Blastocystosis in Patients With Gastric Cancer: a Study With Control Group
(Galenos Publishing House, 2023) Gezici, A.; Cengiz, Z.T.; Yılmaz, H.; Aydemir, S.
Objective: The aim of this study was to determine the prevalence of opportunistic parasites and Blastocystis spp. in patients with gastric cancer (CA) and to determine the significance of these parasite. Methods: The patient group and the control group were composed of 100 people each. The stool samples were examined under the microscope for intestinal parasites with the native-Lugol method. Then, samples were multiplied by formol-ethyl acetate method and stained with modified acid-fast method. Results: Intestinal parasite positivity was indicated in 14% of the gastric CA, and 2% of the healthy individuals (p=0.001). Blastocystis spp. (p=0.009) was identified in 11%, Cryptosporidium spp. was identified in 4%, G. intestinalis was identified in 2%, and C. cayetanensis was identified in 1% of the patient group. There were significant differences between the intestinal parasite positivity (p=0.012), abundant Blastocystis spp. positivity (p=0.041) and all Blastocystis spp. positivity (p=0.037) in patient and control groups. Most of the patients who were positive for parasites had diarrhea. Conclusion: Based findings, it was concluded that it would be beneficial to evaluate gastric CA patients, especially those with diarrhea, for intestinal parasites. © 2023 Turkish Society for Parasitology.
