Purpose: Prenatal screening for antibodies to Toxoplasma gondii (T. gondii), rubella virus and cytomegalovirus (CMV) infectious agents is an important tool in this process. The aim of this study was to determine the seroprevalence of these infections through antenatal screening in Kocaeli region. Material and Methods: 1972 samples of sera were tested for antibodies to TORCH agents known to cause serious congenital infections: T. gondii, rubella, CMV. Anti-Toxoplasma, anti-rubella and anti-CMV IgM and IgG antibodies were assayed by ELISA method using Abbott kits (Axsym, Abbott, USA) according to the manufacturer’s instructions. Results: Of 1972 pregnant women, seropositivity for anti-toxoplasma IgG antibody was found in 952 (48.3%), while 8 (0.4%) of the subjects tested were positive for the anti-Toxoplasma IgM antibody only, and 31 (1.6%) of the subjects tested were positive for anti-Toxoplasma IgG+IgM antibodies together. The seropositivities for anti-rubella IgG, IgM and IgG+IgM together were found in 1896 (96.1%), 4 (0.2%) and 35 (1.8%) of the pregnant women, respectively. The seropositivities for anti-CMV IgG, IgM and IgG+IgM together were found in 1900 (96.4%), 13 (0.7%) and 37 (1.9%) of the pregnant women, respectively. Conclusion: Widespread population screening may contribute to the prevention of congenital infections due to TORCH agents. Because of the high seropositivity of T. gondii, rubella and CMV in pregnant women, preventive measures should be taken.

When dealing with keratitis in children, acanthamoeba should be considered even without history of contact lens usage or trauma.

The aim of this study was to investigate the seroprevalence of Helicobacter pylori (HP) in patients with coronary atherosclerosis and acute coronary syndromes. We enrolled 152 patients (group I, 73 patients with acute coronary syndrome; group II, 79 patients with chronic stable angina) and 22 control subjects. An enzyme-linked immunosorbent assay for immunoglobulin (Ig) G test for HP diagnosis was used on all enrolled subjects. C-reactive protein (CRP) was also measured in all patients as an inflammatory marker. Seropositivity rates for HP were significantly higher in patients with coronary artery disease than in controls (80.2% versus 54.5%; P < 0.05). Although CRP level was significantly higher in group I than in group II (1.72 +/- 2.89 mg/dl versus 0.53 +/- 0.63 mg/dl, P < 0.0001), HP infection rates were similar between groups (86.3% versus 74.6%, P > 0.05). Infection with HP may influence atherogenesis through low-grade, persistent inflammatory stimulation. However, our data show evidence of increased systemic inflammation in patients with acute coronary syndrome, which was unrelated to an increased HP seropositivity.

This study supports the theory that toxoplasmic agents may have a role in the aetiology of schizophrenia.

The aims of this study were to determine the susceptibilities to macrolide and tetracycline antibiotics and emm type distribution of Streptococcus pyogenes strains isolated in the Kocaeli University Hospital, Turkey. A total of 127 S. pyogenes clinical isolates were tested. Eleven (9%) isolates were resistant to erythromycin, and 23 (18%) isolates were resistant to tetracycline. Ten of the erythromycin-resistant isolates were also resistant to tetracycline. By the triple-disk test, all erythromycin-resistant isolates showed the inducible macrolide-lincosamidestreptogramin-C phenotype and harbored erm(TR) gene. tet(O) was the most common tetracycline resistance gene. Among erythromycin-tetracycline coresistant isolates, seven harbored the tet(O) gene. emm 4, emm 1, emm 2,114, and emm 89 were the most common emm types. These isolates were more susceptible to erythromycin. There was considerable emm type heterogeneity in macrolide or tetracycline resistant isolates. According to our knowledge, this is the first study in which emm type distribution is investigated in Turkey. More comprehensive studies are needed to obtain true information about the epidemiology of macrolide and tetracycline resistance and emm type distribution in Turkey.

Candida species are generally identified by conventional methods such as germ tube or morphological appearance on corn meal agar, biochemical methods using API kits and molecular biological methods. Alternative to these methods, rapid and accurate identification methods of microorganisms called matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDİ-TOF MS) has recently been described. In this study, Candida identification results by API Candida kit, API 20C AUX kit and identifications on corn meal agar (CMA) are compared with the results obtained on Vitek-MS. All results were confirmed by sequencing internal transcribed spacer (ITS) regions of rDNA. Totally, 97 Candida strains were identified by germ tube test, CMA, API and Vitek-MS. Vitek-MS results were compatible with 74.2 % of API 20C AUX and 81.4 % of CMA results. The difference between the results of API Candida and API 20C AUX was detected. The ratio of discrepancy between Vitek-MS and API 20C AUX was 25.8 %. Candida species mostly identified as C. famata or C. tropicalis by and not compatible with API kits were identified as C. albicans by Vitek-MS. Sixteen Candida species having discrepant results with Vitek-MS, API or CMA were randomly chosen, and ITS sequence analysis was performed. The results of sequencing were compatible 56.2 % with API 20C AUX, 50 % with CMA and 93.7 % with Vitek-MS. When compared with conventional identification methods, MS results are more reliable and rapid for Candida identification. MS system may be used as routine identification method in clinical microbiology laboratories.
