The Significance of Opportunistic Parasitosis and Blastocystosis in Patients with Gastric Cancer: a Study with Control Group.

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.

Prevalence of Fascioliasis in Slaughtered Cattle in Agri Province.

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.

Investigation of Anti-Toxoplasma gondii Antibodies in the Hemodialysis Patients with ELISA Method

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 Odabas 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.

The Importance of Antioxidant Enzymes and Oxidative Stress in Human Fascioliasis

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. Amaç: Bu çalismanin amaci, Fasciola hepatica ile enfekte hastalarda süperoksit dismutaz (SOD), glutatyon peroksidaz (GPx), katalaz (CAT) ve malondialdehit (MDA) düzeylerini belirlemek ve fascioliasisli hastalarda bu parametrelerde farklilik meydana gelip gelmedigini ortaya koymaktir. Yöntemler: Hasta grubu, F. hepatica pozitif olan 140 hastadan; kontrol grubu ise bu parazit yönünden negatif bulunan ve baska herhangi bir hastaligi bulunmayan 140 saglikli kisiden olusturuldu.

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.

Evaluation of Intestinal Parasites and Some Clinical Symptoms in Children with Diarrhea

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 Igdir 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.

Frequency of Intestinal Parasites in Substance Abusers

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 Yil 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.

Single-strand conformation polymorphism-based genetic characterization of the Cyclospora cayetanensis strains collected from different provinces in Turkey.

INTRODUCTION AND OBJECTIVE: Cyclospora cayetanensis, a coccidian protozoan species, has been recently found to cause diarrhea in all age groups in immunocompetent and immunocompromised individuals in most regions of the world. This study aimed to conduct the molecular detection of C. cayetanensis and to determine the genetic diversity of the 18S ribosomal RNA (rRNA) gene sequence of C. cayetanensis isolated from individuals living in different provinces in Turkey by using PCR-single-strand conformation polymorphism (SSCP). MATERIAL AND METHODS: A total of 22 subjects were included in the study. Fourteen of the subjects were female and eight were male, with ages ranging between 7-65 years. Stool specimens were examined using wet mount and modified acid-fast staining methods, which revealed the presence of oocysts in the samples. The 18S rRNA ITS-1 Ccits37f-GCTTGCTATGTTTTAGCATGTGG and Ccits501r-GCACAATGAATGCACACACA gene regions were used as primers. The PCR products were analyzed by agarose gel electrophoresis and visualized on a UV transilluminator. For the SSCP, the PCR products were denatured with formamide, run for 16 h in 6% (49:1) polyacrylamide gel, and then imaged with silver staining. RESULTS: SSCP assay was performed given that the DNA strands demonstrated different folds; the DNA strands contain different nucleotides based on the PCR-SSCP results for the Cyclospora strains collected in 4 provinces. Moreover, 3 different band profiles were observed in the investigated samples. A slight mutation difference was observed among the strains collected. CONCLUSIONS: Further comprehensive studies involving more C. cayetanensis-positive specimens and utilizing different mutation screening methods are warranted to demonstrate mutation differences in Cyclopora strains in Turkey.

An Oral Myiasis Case Caused by Diptera (Calliphoridae) Larvae in Turkey

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 Yil 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.

A Rare Case of Secondary Hydatid Cyst: Uterus and Colon Locations in the Same Patient

The aim of the present study was to present a case with secondary hydatid cysts in both uterus and colon. The patient was a 71-year-old female living in Hakkari, Turkey. She was admitted to the Van Yuzuncu Yil University Faculty of Medicine Medical Center with complaints of chronic abdominal and pelvic pain, and swelling in the abdomen. First, the sagittal T2 weighted magnetic rezonance imaging (MR) showed a type-3 cyst hydatid with daughter vesicles located at the posterior of uterus. Later, MR revealed a type-2 cystic lesion with detached membrane adhered to the anterior wall of colon and it was reported to be associated with abdomen. When the previous liver surgery history of the patient was kept in mind, the new finding was suggestive of a secondary cystic hydatid . In conclusion, it is possible to diagnose secondary cystic echinococcosis in patients with a history of primary cyst surgery in liver or any other organ by combining the symptoms and imaging findings.

A Comprehensive Retrospective Study: Intestinal Parasites in Human in Van Province

Objective: The aim of present study was to retrospectively determine the prevalence of intestinal parasites in patients, who were referred to Parasitology Laboratory in Van Yüzüncü Yil University, Faculty of Medicine during an 11-year period. Methods: Stool samples of 69633 individuals admitted to the outpatient clinics in the hospital were initially evaluated with native-Lugol, and then by flotation, sedimentation, trichrome staining, modified acid-fast staining and ELISA methods. Results: Twenty-four parasite species were identified in parasite-positive patients. At least one or more parasite species were found in 34.1% of all patients. The most commonly observed parasite was Blastocystis hominis (26.5%). Among pathogen parasites, Giardia intestinalis (G. intestinalis) was detected in 9.3%, Ascaris lumbricoides (A. lumbricoides) was detected in 2.5%, Entamoeba histolytica/Entamoeba dispar in 0.8%, Cystoisospora belli in 0.004%, Fasciola hepatica in 0.04%, Dicrocoelium dendriticum in 0.001%, Strongyloides stercoralis in 0.001% and hookworm in 0.001% of the patients. Conclusion: It was determined that, pathogen parasites such as G. intestinalis and A. lumbricoides were still observed at high rates in Van province, especially in children, and the problem of parasitosis is still continuing, although the prevalence of parasites has declined when compared to the previous years.

Comparison of microscopy, ELISA, and real-time PCR for detection of Giardia intestinalis in human stool specimens

Background/aim: This study included patients who had digestive system complaints between August 2015 and October 2015. The research was designed to compare conventional microscopy with an antigen detection ELISA kit and the TaqMan-based real-time PCR (RT-PCR) technique for detection of Giardia intestinalis in human stool specimens. Materials and methods: Samples were concentrated by formalin-ether sedimentation technique and microscopic examinations were carried out on wet mount slides. A commercially available ELISA kit (Giardia CELISA, Cellabs, Brookvale, Australia) was used for immunoassay. DNA was extracted from fecal samples of about 200 mg using the QIAamp Fast DNA Stool Mini Kit (QIAGEN, Hilden, Germany) and the LightCycler Nano system (Roche Diagnostics, Mannheim, Germany) was used for the TaqMan-based RT-PCR assay. Results: A total of 94 stool samples, 38 of them diagnosed positive (40.4%) and 56 of them diagnosed negative by microscopy, were selected for evaluation by antigen detection and molecular assays. The prevalence of G. intestinalis infection was found as 46.8% (n: 44) and 79.8% (n: 75) by ELISA and RT-PCR, respectively. RT-PCR revealed by far the highest positivity rate compared to the other two methods. The difference between these methods was found to be statistically significant (P < 0.05). In comparison to PCR, the sensitivity and specificity of microscopy and ELISA were 50.7% and 100% and 53.3% and 79%, respectively. Conclusion: RT-PCR seems to be much more sensitive and beneficial for rapid and accurate diagnosis of G. intestinalis in human stools.

Cyclospora cayetanensis, Opportunistic Protozoan Parasite, in Van Province, Turkey: A Report of Seven Cases.

The aim of this study is to report seven Cyclospora cayetanensis (C.cayetanensis) cases determined in Yuzuncu Yil University Medical Faculty Parasitology Laboratory, Van province, Turkey. In the study native-Lugol, formalin-ethyl acetate and modified acid-fast staining methods were performed to stool samples of the patients sent from outpatient clinics of the hospital. All of the patients infected with C. cayetanensis were older than 15 years. In our cases there were not a history of international travel. Only one of our seven cases was immunosuppressed. Trimethoprim-sulfamethoxazole (160/800 mg) was administered for the treatment of the patient. In conclusion, it was understood that the physicians should consider cyclosporiosis in the patients with diarrhea and abdominal pain.

Prevalence of Entamoeba spp. in Stool Samples of Patients with Amebiasis Suspect by Native-Lugol and ELISA.

OBJECTIVE: This study aimed to determine the prevalence of Entamoeba spp. in suspected stool samples submitted to our laboratory. METHODS: In this retrospective study, stool samples of 998 patients with suspected amebiasis were sent from various clinics and services to our laboratory and were investigated by native-Lugol and enzyme-linked immunosorbent assay (ELISA) [for Entamoeba spp. antigen (Ridascreen® Entamoeba)] between January 2010 and December 2014. RESULTS: By the end of the study, it was shown that 8.5% (85) of 997 patients, 7.45% (39) of males and 9.8% (46) of females whom amoeba antigen inspected in their stool samples, were positive. No parasite was identified by the saline-Lugol method. The highest antigen positivity was detected in the 25-44-year-old group with 11% positivity, and a high positivity of 23.2% was seen in March. CONCLUSION: These results demonstrate that amebiasis is still a major health concern for our region. Although no parasite was detected during microscopic examinations, the detection of antigen positivity by ELISA reveals that microscopic examinations require experience and utilizing only microscopic examinations may lead to overlooks. To obtain more reliable results in diagnosis, ELISA analyses that use E. histolytica-specific monoclonal antibodies should be applied in addition to microscopic methods.

Cystoisospora sp. Infection Determined in Immunosuppressed and Immunocompetent Children: Three Cases Report.

The aim of this study was to present three cystoisosporiasis cases diagnosed in pediatric patients of the Yuzuncu Yil University Medical Faculty. In the study, stool samples of the patients were evaluated by native-Lugol and modified acid-fast staining methods in the Parasitology Laboratory. The first case was a 4-year-old male child diagnosed with acute lymphoblastic leukemia (ALL). It was reported that the patient had abdominal pain, and permanent bloody and mucous diarrhea (8-10 times a day) was present for almost 1 week after the beginning of ALL treatment. The second case was a 10-year-old boy diagnosed with depression. The patient was brought to our hospital by his parents with complaints of abdominal pain, diarrhea, lack of appetite, weight loss, and fatigue persisting since 1 month in addition to headache, fear, sleeplessness, and waking up with cry. The third case was a 13-year-old boy who complained of abdominal pain, diarrhea (rare occasions), lack of appetite, and headache for 2 months. These patients had not traveled abroad. The cases were treated successfully with co-trimoxazole. Our results suggest that all patient groups with diarrhea and abdominal pain should also be considered in cystoisosporiasis.

Seroprevalence of human fascioliasis in Van province, Turkey.

BACKGROUND/AIMS: Fasciola hepatica is a rare zoonotic parasite that infects the liver of many mammals including humans. The aim of this study was to determine the seroprevalence of fascioliasis in Van province by ELISA (antibody detection) on the assumption that not all cases could be detected by stool examination alone. MATERIALS AND METHODS: A total of randomly selected 1,600 patients, directed from affiliated outpatient clinics to Yüzüncü Yil University Medical Faculty Parasitology Laboratory, were enrolled in the study. Their mean age was 44.44±19.00 years. Blood samples were collected from all the patients, and their stool samples were examined. For the stool examination, native-lugol and sedimentation (in formalin-ethyl acetate) methods were employed. ELISA for F. hepatica was performed on the blood samples from all patients. Seropositive patients were treated with triclabendazole. RESULTS: F. hepatica was detected by ELISA in 89 (5.6%) of the 1,600 patients, but eggs were identified on the stool examination in only 29 (1.8%) patients. The prevalence of F. hepatica was higher in females (7.2%) than in males (4.2%) and was higher in the ≥36-year age group (6.7%) than in the ≤35-year age group (4.4%). Abdominal pain (93.3%), fatigue (88.8%), and weight loss (69.7%) were the most common symptoms. Eosinophilia was present in 89.9% of the patients. All seropositive patients had a history of eating raw aquatic plants. CONCLUSION: Stool examination alone is not sufficient to diagnose F. hepatica. Serological tests such as ELISA must be used together with stool examination.

[Urogenital Myiasis Caused by Psychoda albipennis (Diptera: Psychodidae) in a Woman in Siirt]. / Siirt'te Bir Kadin Hastada Psychoda albipennis (Diptera: Psychodidae)Kaynakli Ürogenital Miyaz.

Urogenital myiasis cases occurring with the settlement of larvae of flies belonging to the order Diptera are facultative and are rarely encountered in humans. In this study, urogenital myiasis caused by Psychoda albipennis in a 20-year-old female patient was presented. The patient was admitted to our hospital with complaints of nausea, vomiting, and dysuria and claimed that she saw motile larvae in her urine. Five larvae collected from the patient's urine were microscopically examined, and they were identified as fourth-stage larvae of Psychoda albipennis. Complaints of the patient ceased after the application of an antibiotic and urinary antiseptic. It was concluded that myiasis should be considered in patients with urogenital complaints.

[Infestation of the human digestive system with beetle larvae (Coleoptera: Cantharidae): a case report]. / Kinkanatli Larvalarina (Coleoptera: Cantharidae) Bagli Sindirim Sistemi Enfestasyonu: Bir Olgu Sunumu.

This study was conducted to report the digestive system infestation caused by the larvae of Coleoptera in a female pediatric patient. She was admitted to our hospital with the complaints of emergence of insect larvae from her vomit and feces, abdominal pain, inguinal pain, lack of appetite, hair loss, excessive cleaning behavior, extreme irritability, and distractibility. The larvae observed typically had the morphology of the larvae of insects related to the Cantharidae family in the Coleoptera order. For treatment, a single dose of albendazole (400 mg) was used. Consequently, in the present case, it was seen that the larvae of Coleoptera incidentally taken orally could continue to live for a period in the digestive tract of people, without losing vitality, and the larvae caused a variety of symptoms due to both their toxic agents and the possible irritation they caused.

OBJECTIVE: This study was performed to present the distribution of intestinal parasites in parients admitted to the Parasitology Laboratory of the Health Research and Training Hospital of Yüzüncü Yil University in 2009. METHODS: A total of 6267 patients (3037 female, 3230 male; 3798 of 13 years and under, 2469 of 14 years and over) were included. The stool samples were examined by native-Lugol, flotation and sedimentation methods in the Parasitology Laboratory of the hospital. Trichrome and modified acid-fast staining methods were also applied to suspicious stools. RESULTS: One or more than one parasite species were found in 28.5% of 6267 examined stool samples. Parasitosis was determined in 28% of female and 29% of male. Distribution of the parasites determined in the patients was as follows: 15.4% Blastocystis hominis, 6.6% Giardia intestinalis, 4.9% Entamoeba coli, 3.2% plenty B. hominis, 1.7% Chilomastix mesnili, 1.3% Hymenolepis nana, 0.7% Iodamoeba butschlii, 0.5% Ascaris lumbricoides, 0.1% Entamoeba histolytica/Entamoeba dispar, 0.1% Endolimax nana, 0.1% Enteromonas hominis, 0.1% Trichomonas hominis, 0.1% Cyclospora cayetanensis, 0.1% Enterobius vermicularis, 0.03% Entamoeba hartmanni, 0.03% Dicrocoelium dendriticum,0.03% Taenia saginata and 0.02% Trichuris trichiura. CONCLUSION: This research shows that the intestinal parasitosis problem still continues in the province.

[Case report: hookworm infection in a patient with severe anemia]. / Olgu Sunumu: Agir Anemi Tablosu Olan Bir Hastada Cengelli Solucan Infeksiyonu.

In this study, a patient who was hospitalized with a severe anemia in the Internal Medicine Clinic of the Health Research and Application Hospital of Yüzüncü Yil University for one week is presented. The patient had fatigue, paleness and dizziness for one month and approximately 12 kg weight lost for four mounts previous to admission.. Severe iron deficiency anemia was diagnosed in the patient by laboratory analyses. Because there were no hematologic factors associated with severe anemia, the stool examination was also performed. In the Parasitology Laboratory, stool microscopy of the patient revealed numerous ova of hookworm. General condition of the patient well improved with anti-parasitic and anti-anemia treatment. It was concluded that patients with iron deficiency anemia diagnosed in health centers should be also examined for the intestinal parasitic diseases encountered rarely, and physicians should consider non-endemic parasitic diseases in their provinces.
