WOS: 000419616300010, Myiasis is an invasive diseases caused by larvae of various Dipterian flies. Subcutaneus myiasis cases are commonly observed by Dermatobia hominis larvea. A 26-year-old female patient with a history of travel abroad. Brasil diagnosed with subcutaneous myiasis originating from D. hominis. After spending six months in Amazon forests, Brasil, patient observed two small erythematous papules on right lower quadrant abdomen and delicate and itchy in the sacral region. Two larvae removed from the papules were sent to Ege University Medical Faculty Polyclinic of Infectious Diseases and sent to the parasitology polyclinic for the identification of larval species. After the necessary macroscopic and microscopic examinations, D. hominis was obtained as aresult of myiasis effect. Geographically, natural distribution of D. hominis is South American countries. In this case report we want to introduce the mechanism of egg distribution and take attention to the importance of medical history on myiasis cases. Since it is the first case seen in Turkish patients, it is thought to be presented in terms of revealing the importance of anamnesis in myiasis cases.

Echinococcus granulosus antigen B fraction (AgB) was evaluated for its prognostic value in the serological follow-up of cystic echinococcosis (CE), compared to crude hydatid fluid (HF) as well as soluble somatic Echinococcus multilocularis antigen (Em). The sensitivity and specificity of enzyme-linked immunosorbent assays (ELISA) were compared examining 177 sera from patients with different clinical courses and outcome of CE and with other parasitic infections. AgB-ELISA in comparison to confirmed cystic echinococcosis has 96.4 % sensitivity and 97.2 % specificity, with 93.1 % positive predictive value and 98.6 % negative predictive value. The HF-ELISA was more sensitive than the AgB-ELISA, but its specificity was lower. Our results indicate that AgB-ELISA was more satisfactory for seroconfirmation of acute echinococcosis than HF-ELISA. Moreover, the AgB-ELISA has a potential key role in control measures implemented in patients undergoing surgery. In sera of patients more than 3 months after the treatment, no antibody response to antigen B was detected; however, with conventionally used HF-ELISA, they were still positive. The AgB is recommended for the confirmatory diagnosis. AgB-WB allocated low background with typical "triplet" bands at 8-12-16 kDa.

Routine laboratory diagnosis of Pneumocystis jirovecii is currently achieved by PCR in almost all laboratories with sufficient equipment due to its high sensitivity and specificity compared to staining methods. A current issue that limits the reliability and sensitivity of PCR is the degree of inhibition caused by inhibitory substances in respiratory samples. The present study aimed to analyse the degree and frequency of inhibition in real-time PCR detecting P. jirovecii in respiratory specimens submitted to a Pneumocystis pneumonia (PcP) diagnosis laboratory in Ege University Medical School, Turkey. Between July 2009 and December 2010, 76 respiratory specimens [63 bronchoalveolar lavage (BAL) fluid, 10 sputum samples, two tracheal aspiration fluid and one thoracentesis fluid] obtained from 69 PcP-suspected patients were investigated for the presence of P. jirovecii using real-time PCR targeting the cdc2 gene. Of these samples, 42 of the specimens were stained and examined by microscopy according to the request of the clinicians. PCR was positive in 15 specimens in the initial run. Of the remaining 61 samples, 41 of them were negative with positive internal inhibition controls (i.e. true-negative group). The frequency of inhibition in the initial run was 26.31 % (20/76) as determined by spiked negative controls. All of the inhibited samples were resolved after 1 : 2, 1 : 5, 1 : 10 and 1 : 20 dilutions. P. jirovecii was detected by PCR in two inhibited specimens after retesting with diluted samples which were also positive by microscopy. The incidence of P. jirovecii in respiratory specimens was 22.36 % (17/76) as determined by real-time PCR and 7.14 % (3/42) by microscopy. Overall, the incidence of P. jirovecii in respiratory samples was 23.68 % (18/76) as detected by both methods. In conclusion, inclusion of spiked positive controls in each sample and retesting with diluted samples to resolve inhibition increased the reliability of the real-time PCR assay in terms of determining false-negative results and influencing the treatment of the patient. Furthermore, results of the present study determined for the first time the frequency and degree of inhibition in a real-time PCR detecting P. jirovecii in respiratory specimens during routine diagnosis of PcP.

The oral cavity is suitable for invasion of many microorganisms. Entamoeba gingivalis (E.gingivalis) and Trichomonas tenax (T.tenax) settle in the oral cavity of patients with poor oral hygiene and gingival disease. In the present study, two slide specimens were prepared from the cole region of the teeth of 46 persons for investigation of the parasites. One of the slide specimens was dried in the air while the other one put into fixative and they were stained with trichrome and Giemsa stains. The two staining methods were used for 36 samples and only Giemsa, for 10 samples. E. gingivalis was positive in 7 (19.44%) out of 36 samples stained by the trichrome stain while T. tenax was positive in one (2.17%) out of 46 samples stained by Giemsa stain. Parasitic infections were found to be positive in seven (21.2%) specimen from 33 patients with periodontal disease and in one (7.69%) specimen from 13 healthy controls. Dental policlinics are generally far from parasitology laboratories and microscopical wet mount examination can not be performed. Therefore dentists can send the specimens and have the parasites diagnosed with Giemsa and trichrome staining methods as an alternative to wet mount examination.

Cyclospora spp. which are coccidian parasites are rare gastroenteritis pathogens. The first cyclosporiasis case in Turkey was reported in 1998 in a patient with AIDS. In this paper we report a case of Cyclospora gastroenteritis, in a patient who was admitted to our hospital and who had had diarrhea, abdominal pain and nausea for ten days. In the anamnesis it was learned that he had travelled to the Black Sea region and had drunk muddy and cloudy water. His physical examination was normal except for increased bowel sounds. There were no leukocytes or erythrocytes in the direct microscopy of the stool and bacteriologic culture did not yield any enteropathogen. Cylospora oocyysts were seen in the parasitologic exmination. The patient was treated with cotrimaxasole (2x1,160/800 mg tablet). There was no pathogen in the repeated stool examination. Our case suggests that parasitologic examination should not be neglected in longlasting diarrhea cases and occasionally Cyclospora may be the causative agent.

The aim of this study was to determine the parasite frequency in 3925 patients during 2005 from January 1- December 31 in the parasitology laboratory of the Ege University Medicine School. During the laboratory investigation, 3925 fecal specimens and cellophane tapes from the patients were examined. After the microscope examination of 3925 feces samples, it was found that 590 (15.03%) of these samples contained one or more intestinal parasites. Blastocystis hominis (4.96%), Cyclospora spp. (1.91%), Enterobius vermicularis (1.86%), Entamoeba coli (1.78%) and Giardia intestinalis (1.78%) were the five most common parasites obtained during the examination.

Scabies is an ectoparasitosis caused by Sarcoptes scabiei. Clinical types can be highly variable. There might be a problem in diagnosis due to difficulty in detecting the parasite and atypical clinical features. Delayed diagnosis may be the cause of outbreaks for people living in overcrowded places such as poorhouses, orphanages and barracks. The different types of treatment have been discussed as well as rules for prevention.
