ABSTRACT
Objective: The aim of this study is to determine the prevalence of intestinal parasites in patients admitted to University of Health Sciences Türkiye (UHS) Van Training and Research Hospital. Methods: A total of 300 patients between the ages of 18-90 who applied to UHS Van Training and Research Hospital with gastrointestinal complaints and were referred to the parasitology laboratory between September 2021 and December 2021, and 100 patients without any chronic disease and gastrointestinal complaints in the control group were included in the study. Stool samples taken from patients included in the study and individuals in the control group were analyzed by native-lugol and modified acid-fast staining methods. Results: In the study, intestinal parasites were detected in 41 (13.3%) of 300 patients in the patient group and in seven (7%) of 100 individuals in the control group. The highest rate of Blastocystis species (Blastocystis spp.) (5.7%) was found in the patient group. Entamoeba coli 3%, G. intestinalis 2.7% and Cryptosporidium species (Cryptosporidium spp). 2.3% were found among the other species detected. In addition, a statistically significant correlation was found between the incidence of parasites and abdominal pain (p=0.022) and nausea (p=0.029). Conclusion: As a result; it was concluded that intestinal parasites are still an important health problem in patients with gastrointestinal complaints and intestinal parasites should definitely be considered in this patient group.

OBJECTIVE: In this study, it was aimed to reveal the frequency of fascioliasis in cattle slaughtered in the slaughterhouses of Agri 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 Agri 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.

Background: We aimed to determine the frequency and subtype of B. hominis in diabetic patients. Methods: One hundred and fifty diabetic patients and 100 healthy people without any chronic disease were included in the study. Stool samples were analyzed by native-Lugol, condensation, trichrome staining and PCR methods. Results: In 150 patients with diabetes; B. hominis was detected in 38 (25.3%) by PCR, in 34 (22.7%) by native-Lugol and trichrome staining. In the control group, 14 (14%) out of 100 subjects were positive by PCR, and 10 (10%) were positive by native-Lugol and trichrome staining. In the statistical evaluation, a significant difference was found between gender (P=0.023), age (P=0.045; ≤35 and >35 comparison), duration of diabetes (P=0.04), the HbA1c value (P=0.023; <8 and ≥8 comparison), and B. hominis positivity. ST1 was determined in 76.9% of patients with diabetes, and ST2 was determined in 23.07%. Considering the 3 methods, B. hominis positivity was detected in 40 patients (26.7%) in diabetic group and in 14 participants (14%) in the control group (P=0.011). Conclusion: B. hominis is a factor to be considered in patients with diabetes. Herein, the most common subtype detected in the patients with diabetes mellitus was ST1, but this result was not considered sufficient to reveal the importance of the subtype factor in the pathogenicity of B. hominis in patients with diabetes. In this context, there is a need for more comprehensive studies in both diabetic and other immunocompromised patient groups.
ABSTRACT
Increasing world population parallelly also brings an increase in food production and consumption. As food consumption increases, so do foodborne infections. In cases where adequate food safety and hygiene is not provided in places such as restaurants, dormitories, prisons, hospitals where mass feeding is made outside the home, many parasitic agents can be transmitted to people through food. People working in the food processing and distribution sector and who are in the position of porters play an important role in the spread of parasites, as they can transmit parasitic agents to food through fingernails and hands. Parasites such as Enterobius vermicularis, Entamoeba histolytica, and Giardia intestinalis can be transmitted to food and then to patients through nails and hands. This study was planned to investigate the presence of parasites in hospital food production and distribution workers, such as cooks and waiters, using various methods. Stool and serum samples were taken from 100 food production and distribution workers. Stool samples were examined by native-Lugol, concentration, trichrome, acid-fast staining, and cellophane tape methods. E. histolytica antigen in stool and Toxoplasma and Taenia antibodies in serum were searched by enzyme-linked immunosorbent assay. Parasites were detected in 59% people, and 41 were evaluated as negative. This positivity was 71.9% (23/32) in the 45-61 age range. Blastocystis sp. (27%), Toxoplasma (25%), E. histolytica (10%), Taenia spp. (7%), E. vermicularis (7%), Entamoeba coli (7%), G. intestinalis (5%), Chilomastix mesnili (1%), and I. butschlii (1%) were detected in food handlers. High Toxoplasma antibody positivity (25%) suggests the possibility of transmission to kitchen workers through ways, such as infected raw meat. However, the detection of E. histolytica, Taenia spp., E. vermicularis, G. intestinalis parasites in workers at significant levels poses a significant risk for society consuming these foods. As a result, it is important to investigate the presence of parasites in the employee dealing with food production and distribution to protect patients from parasitic infections especially in hospitals where the people are immunocompromised and more susceptible, and where mass meals are eaten.

OBJECTIVE: In this study, it was aimed to investigate the physical and chemical properties of different spring waters and parasitic factors with different methods. METHODS: This study was carried out on 69 water samples collected from different spring waters in and around Igdir Province in April and June 2021. The samples were analyzed by native-Lugol, modified acid-fast staining, and nested polymerase chain reaction (nPCR). In addition, altitude (meter) and pressure (mmHg) measurements were made at the point where the water samples were taken. RESULTS: One or more parasites were detected in 27.5% of the 69 water samples examined. Only C. cayetanensis was found in 13% of the samples, only Cryptosporidium spp. in 10.1%, only Giardia spp. in 1.4%, only C. cayetanensis and Giardia spp. in 1.4%, only C. cayetanensis, Cryptosporidium spp., and Giardia spp. in 1.4%. Only Giardia spp. cyst (4.3%) was detected by the direct examination method. While C. cayetanensis and Cryptosporidium spp. oocysts were detected in 8.7% and 7.2% of the samples by the modified acid-fast staining method, C. cayetanensis was detected in 15.9% and Cryptosporidium spp. was detected in 11.6% of the samples by nPCR. When the C. cayetanensis and Cryptosporidium spp. positivity rates were compared according to the characteristics of the water, there was no statistical difference between the altitude, salinity, pH, mmHg, and temperature (kelvin) values, but a significant correlation was found between the amount of dissolved oxygen and Cryptosporidium spp. positivity (p=0.047). CONCLUSION: Cryptosporidium spp., C. cayetanensis, and G. intestinalis are important waterborne pathogens that can cause epidemics. It is our belief that in order to reduce the risk of contamination of these parasitic factors with spring waters, public awareness should be raised, infrastructures should be improved, and new water treatment techniques, such as ultraviolet, ozonation and monitoring systems, should be used.

Objective: This study aimed to investigate the frequency of gastrointestinal helminth parasites in stray dogs in Agri 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 Agri and the districts of Diyadin, Dogubayazit, Eleskirt, Hamur, Patnos, Tasliçay, 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 Agri, it was revealed that stray dogs in Agri 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.
