RESUMEN
Bartonella species cause several diseases in humans such as cat stratch disease, bacillary angiomatosis, peliosis hepatis, endocarditis, Carrion disease and trench fever. Cat scratch disease and bacillary angiomatosis cases have already been reported in Turkey. Studies from our region, namely Aydin (a province located at Western Anatolia, Turkey) indicated that mean Bartonella henselae IgG seropositivity rate is 11.5% in risk groups and may reach to 26.5% in pet owners. The aim of this study was to determine the seroprevalence of B.henselae and B.quintana in healthy blood donors in our university hospital in Aydin, for estimating the transmission risk via transfusion. The study was designed as a cross-sectional epidemiological study. A total of 333 samples taken from blood donors (49 female, 284 male) who were sequentially admitted to the blood center of the university hospital, in January 2011 were included in the study. All sera were screened in terms of B.henselae and Bartonella quintana IgG antibodies by using two different indirect immunofluorescent antibody (IFA) commercial kits (Vircell, Spain; Focus, USA). Slides were examined at a final magnification of x400 on fluorescent microscope by two different assigned researchers. Fluorescent intensity was graded between 1+ to 4+, and the samples with fluorescence value of ≥ 2+ were considered as positive. The seropositivity rate of IgG antibodies to B.henselae was found as 3.3% (11/333) in blood donors. This rate was 4.1% in female, and 3.2% in male donors, showing no statistically significant difference between the genders (p= 0.668). B.henselae antibody titers were detected as 1/64 in 6 (1.8%), 1/128 in 4 (1.2%) and 1/1024 in 1 (0.3%) patient. All of the B.henselae IgG positive samples also yielded relatively low positivity for B.quintana IgG, possibly indicating cross reactivity. The fluorescence intensity for different kits used was found to be the same in all but one titer. The results reported by two researchers were found to differ only in the samples graded 1+ or below. However, the evaluation differences between the kits and the researchers did not affect the results. It was concluded that B.henselae infection might be found in the blood donors in our region, thus, a detailed questionnaire prior to blood donation might be helpful to prevent transmission of B.henselae by blood transfusion.

Coxiella burnetii is the causative agent of the common zoonotic disease known as Q fever. Human infection is mostly maintained by inhalation of contaminated aerosols that originate from infected birth products, milk and urine. Sexual transmission has also been reported. In pregnant women the disease causes abortion during the first trimester, while at later stages it tends to become chronic causing low birth weight babies and premature birth. The aim of this study was to investigate the prevalence of C.burnetii in women who had miscarriages, their spouses and in a control group composed of women with normal delivery by using serological and molecular methods. A total of 89 cases (58 female, 31 male; age range: 21-64 years, mean age: 33.1 ± 7.6 years) were included in the study. Women who had abortion (n= 36) were recruited along with their husbands (n= 31), and 22 women who had normal pregnancy were accepted as controls. Blood and placental tissue samples (after abortion or normal delivery) were collected from all of the female subjects, while blood samples were collected from the males. C.burnetii IgG and IgM antibodies in the sera of patients and controls were analysed by ELISA and indirect fluorescein antibody (IFA) methods, and the presence of C.burnetii DNA was searched in whole blood and placenta samples by using polymerase chain reaction (PCR). In our study, C.burnetii Phase II IgG antibody positivity rates in women who had miscarriages, their spouses and in women with normal delivery were found as 27.8% (10/36), 38.7% (12/31) and 4.5% (1/22), respectively by ELISA, while those rates were detected as 27.8% (10/36), 41.9% (13/31) and 9.1% (2/22), respectively by IFA which was accepted as the reference method. However C.burnetii Phase I IgM, Phase I IgG and Phase II IgM antibodies were not detected in none of the subjects by both methods. The relatively high seropositivity rate in our study group (25/89; 28.1%) was thought to be associated with high rates of livestock breeding in our region. Although C.burnetii IgG seropositivity rate in in women who had miscarriages was higher than women with normal delivery, the difference was not found to be statistically significant (x2= 2.906, p= 0.088). When the results of the women with miscarriages and their spouses were evaluated together, it was detected that C.burnetii IgG antibodies were not determined in the spouses of four seropositive women (two positive with 1/64, two with 1/128 titer); titer was 1/64 in four women and their spouses and two women with 1/128 titer had spouses with 1/64 titer. The determination of high titer phase II IgG positivity in 13% (4/31) of the spouses of women who had miscarriages was of notice. All of the blood (n= 89) and placenta samples (n= 51, 29 were from aborted and 22 from normal delivered women) were negative for C.burnetii DNA by PCR. In conclusion, since livestock breeding is common in our region, in cases with recurrent abortion and premature births, women and their husbands should be screened for C.burnetii.

BACKGROUND: The aim of this study was to investigate whether in children with middle ear effusions (MEE), adenoid and tonsil tissues are associated with human bocavirus (HBoV). MATERIALS AND METHODS: A total of 124 patients (56 females (45.2%) and 68 males (54.8%)) with chronic adenotonsillitis and serous otitis media under the age of 15 were recruited. Two hundered four samples (113 adenoid (55.4%), 68 tonsil (33.3%), and 23 middle ear effusion (11.3%)) were analyzed for the presence of HBoV using polymerase chain reaction (PCR). RESULTS: HBoV was detected in only 6 (4.8%) adenoid tissue samples each belonging to a different patient. CONCLUSIONS: Our findings are consistent with the results of other studies, reporting approximately 5 - 10% of the samples being positive for HBoV. To understand the detailed role of HBoV in the etiology of RTI in children, further studies would be needed.

Blastoschizomyces capitatus is a rare fungal pathogen that may lead to fatal infections especially in immunosuppressive individuals. In this report, three cases of B.capitatus were presented. The patients were under treatment for acute myeloid leukemia and their blood cultures yielded B.capitatus. The patients clinical conditions deteriorated and they died despite amphotericin B treatment. The isolates were identified by conventional mycological methods and API 20C AUX (Bio-Mérieux, France) system. Antifungal susceptibility test of the strains was performed with Sensititre Yeast One Panel (Trek Diagnostic Systems, USA) and minimum inhibitory concentration (MIC) ranges for amphotericin B, caspofungin, fluconazole, itraconazole, voriconazole, posaconazole, and flucytosine were found as 0.5-1; > 16; 8-16; 0.5; 0.25; 0.5-1 and 0.06-0.25 µg/ml, respectively. Isolated strains were genotyped with RAPD-PCR (Random Amplified Polymorphic DNA-Polymerase Chain Reaction) using Cnd-3, Cnd-4, OPE-03, OPE-18 primers. The strains isolated from the first two cases were found to be genotypically identical, while the strain isolated from the third case was different. Genotypically identical isolates belonged to two patients who were admitted to the hospital with approximately 18 months interval. The other strain with a unique genotype, was isolated from a patient who was admitted to the hospital about two years later than the other two patients. In conclusion, B.capitatus should be considered as an important opportunistic pathogen especially in patients with hematologic malignancies. The data of this study demonstrated that the lowest MIC values for B.capitatus strains were with voriconazole.

Candidemia is a serious clinical picture with a rather high mortality. Early diagnosis and appropriate treatment is crucial in this picture especially in immunocompromised cases. The aims of this retrospective study were to investigate the antifungal susceptibility patterns and to detect the presence of phospholipase, esterase and biofilm production which are excepted as virulence factors of Candida spp. strains and to evaluate the clonal relationships between isolates. A total of 46 Candida spp. Strains isolated from blood cultures of patients of whom eight were newborn and 38 were adults, between the period of February 2005 to July 2010, were included in the study. Of the isolates 17 were identified as C.albicans, 18 were C.parapsilosis, five were C.glabrata, four were C.tropicalis, one was C.guilliermondii and one was C.krusei. Antifungal susceptibility tests were performed by using "Sensititre Yeast One (Trek Diagnostic Systems, USA)" commercial kit. Esterase activity was detected in Tween-80 medium; phospholipase activity in yolk egg agar and biofilm formation was investigated by microplate assay. Strain genotyping was performed by RAPD-PCR (random amplified polymorphic DNA-polymerase chain reaction) by using OPE-03, OPE-18, AP50-1, Cnd-3 and Cnd-4 primers. All strains were found to be susceptible to amphotericin B, voriconazole, posaconazole, and caspofungin. C.krusei strain was defined as resistant (intrinsically) to fluconazole. All strains of C.albicans, C.parapsilosis, C.glabrata, and C.tropicalis were found to be susceptible to fluconazole. Three of five C.glabrata strains were resistant to itraconazole, while the other strains were found to be susceptible. All of the C.albicans strains had phospholipase and esterase activity, however none were biofilm-producing isolates. In contrast all of the C.parapsilosis strains were negative for phospholipase and esterase activity, however all were positive for biofilm formation. Phospholipase activity has not been detected in non-albicans strains; esterase activity were found positive in all of the C.tropicalis strains, while biofilm formation was detected in three C.tropicalis, one C.glabrata and one C.krusei isolates. The results of genotyping demonstrated that C.albicans strains displayed 5-8 different patterns and C. Parapsilosis strains 2-3 patterns with the use of five primers. Among C.parapsilosis strains, 14 were found identical (with the use of all the primers forming a single pattern (pattern A). In conclusion, the Candida spp. Isolated from blood samples were highly susceptible to the tested antifungals, and C.albicans strains had high phospholipase and esterase activity, while C.parapsilosis strains had high rate of positivity for biofilm formation. The predominant pattern amongst C.parapsilosis strains was thought to be related to exogenous dissemination.

Macrolide resistance mechanisms in 89 Streptococcus pneumoniae strains isolated from several clinical samples between February 2007 and May 2009 were investigated. Erythromycin resistance was noted in 35 (40%) S. pneumoniae strains. In these strains, the most frequent resistance phenotype was cMLS(B) (74%), and the most frequent resistance genotype was ermB (82%). Both ermB and mefA genes were positive in 20% of macrolide-resistant strains. While no resistance to vancomycin, linezolid and telithromycin was noted in 89 S. pneumoniae strains, 12 (13%) strains were penicillin resistant, 26 (30%) strains were clindamycin resistant, 35 (40%) were azithromycin resistant, 32 (36%) strains were tetracycline resistant, and 1 (1%) strain was levofloxacin resistant. The serotype distribution of 35 macrolide-resistant S. pneumoniae strains revealed that the most frequent serotype was serogroup 19 (45%). Multidrug resistance was present in 19 (86%) of 22 strains carrying only the ermB resistance gene. No clonal dissemination was noted in the macrolide-resistant pneumococcal strains. These findings suggest that macrolide resistance rates, resistance phenotype and genotype, as well as resistant serotypes of S. pneumoniae strains should be continuously monitored in our country.

Candida species which cause local infections, may also lead to fatal systemic infections. The increasing incidence of non-albicans Candida, especially fluconazole susceptible or resistant dose-dependent C. glabrata, increased the importance of rapid and accurate species level identification for Candida. Rapid and correct identification of C. glabrata is essential for the initiation of the appropriate antifungal therapy. This study was conducted to evaluate the performance of the rapid trehalase test in the diagnosis of C. glabrata isolates. A total of 173 Candida strains isolated from various clinical specimens and identified according to germ tube test, growth on cornmeal Tween 80 agar and the colony morphologies on Mast-CHROMagar Candida medium (Mast Diagnostics, UK), were included to the study. The identification of non-albicans Candida species were also confirmed by API 20CAUX (BioMerieux, France) system. Accordingly 86 (50%) of the isolates were identified as C. glabrata, 48 (28%) C. albicans, 17 (10%) C. krusei, 13 (8%) C. tropicalis, 5 (3%) C. parapsilosis, 3 (2%) C. kefyr and 1 (1%) Cutilis. In order to detect the presence of trehalase enzyme in Condida strains, all isolates were grown on Sabouraud dextrose agar containing 4% glucose and then one yeast colony was emulsified in 50 microl of citrate buffer containing 4% (wt/vol) trehalose for 3 h at 37 degrees C. Presence of glucose which emerged after the action of trehalase on trehalose, was detected by a commercial "urinary glucose detection dipstick" (Spinreacta, Spain). All C. glabrata strains yielded positive result by trehalase test. None C. glabrata isolates were found negative by trehalase test except for one strain of C. tropicalis. In this study, the trehalase test allowed identification of C. globrata with 100% sensitivity and 98.9% specificity. It was concluded that trehalase test is a rapid, cost-effective and simple test that can be used for the accurate identification of C. glabrata.

In recent studies, there have been many arguments concerning Helicobacter pylori being reservoir in adenotonsillar tissue. In this study, our objective was to detect whether adenoid and/or tonsillar tissue of patients diagnosed with chronic adenotonsillitis was a reservoir for H. pylori. This study was performed with 47 patients with the diagnosis of chronic tonsillitits and adenoid hypertrophy. Helicobacter pylori was searched by rapid urease test (RUT) and polymerase chain reaction (PCR). Presence of H. pylori glmM gene (formerly named as ureC gene) was tested using ureC and ureC2 primers. Fifty-five specimens used in the study were made up of 35 adenoid and 20 tonsil tissues. Rapid urease test was positive in three (5.5%) specimens. Helicobacter pylori was not detected in any of the patients by PCR. Further studies are needed to clarify the possible role of H. pylori in upper aerodigestive tract diseases such adenotonsillitis.

The aim of this study was to investigate clinical findings and the effects of trimethoprim-sulfamethoxazole (TMP-SMX) in cases of blastocystosis. A total of 37 cases whose stool specimens were sent to the parasitology laboratory from the outpatient clinics of our hospital for various reasons were included in the study. Only five or more Blastocystis hominis were found during examination with direct wet mount using the 40x objective. The stool specimens were tested for other agents (Salmonella spp., Shigella spp., Escherichia coli H157:07, rotavirus) and cases with one of these were excluded from the study. The cases with blastocystosis were given TMP-SMX for 7 days. After the treatment, the cases were questioned as to symptoms once again, the stool specimen examinations were repeated with the same methods, and the results were evaluated. In 34 (91.89%) out of the 37 cases where B. hominis was found, various clinical symptoms such as stomach ache, flatulence, diarrhea, itching and fever were observed singly and/or together. After the treatment it was found that 36 (97.3%) out of 37 cases improved. This study supports the premise that TMP-SXT is effective in the treatment of B. hominis.

The role of fungi in chronic rhinosinusitis (CRS) remains unknown. Fungi were also determined as one of the responsible agents in the etio-pathogenesis, while several studies found fungi in 6-93% of the cases. The aim of this study is to test the presence of fungi in samples taken from the middle meatus of patients with CRS, using traditional culture methods and polymerase chain reaction (PCR), and to compare the efficacy of these methods. Thirty patients diagnosed with CRS, with or without nasal polyposis, undergoing an operation in the Otorhinolaryngology Clinic, were prospectively included in the study. Nasal mucosa samples from ten patients, who were operated for pathologic evaluation, and without CRS, were used as controls. Nasal samples were taken from each patient by swabbing with a cytology brush. Middle meatus culture samples were taken by using nasal cotton swab, and the polyp and/or sinus mucosa samples were taken during endoscopic sinus surgery. Fungal specific PCR, using 18S rRNA primers and standard cultures, were performed on every sample. All amplicons were sequenced. There was no fungal growth in the Sabouraud dextrose agar (SDA) medium from middle meatus samples and tissue parts. Of 30 tissue and brush samples, 3 and 2 were positive for fungal DNA, respectively. Sequence analysis showed that four amplicons were homologus to Cladosporium herbarum and one to Aspergillus amstelodami. We concluded that fungal etiology is overestimated and fungi rarely play a role in patients with CRS. Large-scale studies should be done using molecular methods.

BACKGROUND: Involvement of the brain by Aspergillus fumigatus, named as invasive aspergillosis, is extremely rare. Definitive diagnosis needs isolation of the fungus from the tissue specimens and its culture. The disease is very resistant to treatment and quickly becomes fatal despite antifungal chemotherapy with AmB preparations, the drugs of choice for the infection. CASE DESCRIPTION: We hereby present a unique case of fungal granuloma of the brain due to A fumigatus, which was cured successfully by intensive antifungal treatment, along with a brief literature review. CONCLUSIONS: Although it is rare, we draw the attention to the fact that early diagnostic procedures with rapid confirmation of Aspergillus infection and an early initiation of therapy are pivotal for a benign clinical course in such cases. A complete regression of the disease could be achieved with medical therapy alone with conventional AmB or liposomal AmB combined with oral itraconazole even if a total surgical excision of the lesions could not be performed in complicated cases, as in our patient.

BACKGROUND: Endophthalmitis is the inflammatory response to invasion of the eye with bacteria or fungi. The incidence of endophthalmitis after cataract surgery varies between 0.072-0.13 percent. Treatment of endophthalmitis with fungal etiology is difficult. CASE PRESENTATION: Case 1: A 71-year old male diabetic patient developed postoperative endophthalmitis due to Aspergillus flavus. The patient was treated with topical amphotericin B ophthalmic solution, intravenous (IV) liposomal amphotericin-B and caspofungin following vitrectomy. Case 2: A 72-year old male cachectic patient developed postoperative endophthalmitis due to Scopulariopsis spp. The patient was treated with topical and IV voriconazole and caspofungin. CONCLUSION: Aspergillus spp. are responsible of postoperative fungal endophthalmitis. Endophthalmitis caused by Scopulariopsis spp. is a very rare condition. The two cases were successfully treated with local and systemic antifungal therapy.

BACKGROUND: Allergic rhinitis is the most common allergic disease in Turkey. Our objective was to determine the prevalence of allergic rhinitis among adults living in Aydin, Turkey. METHODS: A population-based survey was undertaken among adults aged 16-64 years. Allergic rhinitis was confirmed in the subjects screened positive by the clinical examination and specific immunoglobulin E testing. RESULTS: A total of 465 interviews were conducted in spring 2005. The prevalence of allergic rhinitis in the past 12 months was 14.0%. The prevalence rate of clinically confirmable AR was computed as 11.4%. The prevalence was significantly higher among females and in urban areas. Specific IgE were detected for at least one of tested aeroallergens in 34.8% of the subjects with self-reported AR. CONCLUSION: Our study revealed that the prevalence of allergic rhinitis among adults living in the city of Aydin was as high as the prevalence in other regions of Turkey but less than in Europe.

Identification of Candida species is important to guide treatment in vulvovaginal candidiasis which is seen frequently and needs long-term therapy due to recurrence. The aim of this study was to determine the species distribution of Candida isolated from vaginal specimens and evaluation of CHROMagar Candida medium in the laboratory diagnosis. Samples from 80 patients who were clinically diagnosed as vaginitis have been analysed in our laboratory. Colonies appeared on CHROMagar Candida media after 48 hours of incubation at 35 degrees C were evaluated for their colors and characteristics. Candida strains were identified by germ tube test, growth on corn meal Tween 80 agar and when necessary also by API 20 C AUX commercial kit. A total of 84 Candida strains were isolated from 80 patients. Two different Candida species have been isolated from four (5%) of the samples. Among Candida strains isolated, 45 (53.6%) were C. albicans, 29 (34.5%) C. glabrata, 7 (8.3%) C. krusei, and 3 (3.6%) C. kefyr. All of the C. albicans and six of the seven C. krusei isolates have been identified correctly by CHROMagar Candida medium. These results showed that C. albicans is still the most frequently isolated species from vaginal samples. It was concluded that CHROMagar Candida medium is useful for identification of colonies due to frequently seen Candida species and also in differentiation of multiple Candida species grown on the same culture.

BACKGROUND: Intestinal parasitic infections are amongst the most common infections worldwide. Epidemiological research carried out in different countries has shown that the social and economical situation of the individuals is an important cause in the prevalence of intestinal parasites. Previous studies in Turkey revealed a high prevalence of intestinal parasitic infection. The objectives of the current study were to determine the prevalence of intestinal parasitic infections in Aydin among 7-14 years old school children and to identify associated socio-demographic and environmental factors, behavioral habits and also related complaints. METHODS: Multistage sampling was used in the selection of the study sample. A questionnaire, cellulose adhesive and a stool specimen examination were done. RESULTS: A total of 456 stool specimens were collected. 145 students (31.8%) were infected with one or more intestinal parasites. 29 (6.4%) of the students were infected more than one parasite, 26 (5.7%) with two parasites and 3 (0.7%) with three parasites. The three most common were E. vermicularis, G. intestinalis and E. coli. Intestinal parasite prevalence was higher in rural area, in children with less than primary school educated mother, in children who use hands for washing anal area after defecation, and in children who use toilet paper sometimes or never. The relation between child health and mother education is well known. Children were traditionally taught to wash anal area by hand. Toiler paper usage was not common and might be due to low income or just a behavioral habit also. Most of the complaints of the study population were not significantly related with the intestinal parasitic infection. CONCLUSIONS: Intestinal parasitic infection is an important public health problem in Aydin, Turkey. Rural residence, mother education less than primary school, sometimes or never usage of toilet paper, and washing anal area by hands after defecation were the significant associations. Interventions including health education on personal hygiene to the students and to the parents, especially to mothers are required. The ratio of uneducated women should be declined with specific programs. A multisectoral approach is needed.
