ÖZET Myroides odoratus/odoratimimus geçmişte Flavobacterium odoratus/odoratimimus olarak bilinen, aerobik, non-fermentatif, hareketsiz Gram negatif basildir. Genellikle toprak ve suda bulunmakla beraber altta yatan hastalığı bulunanlarda, immunsuprese hastalarda patojen olabilmektedir. Bu çalışmada altta yatan hastalıkları bulunan ve idrar kültüründe M.odoratus/odoratimimus üreyen 56 yaşındaki kadın hasta anlatılmaktadır. Anahtar kelimeler : Altta yatan hastalık, Antibiyotik direnci, İdrar yolu enfeksiyonu, Myroides. ABSTRACT Myroides odoratus/odoratimimus is an aerobic, non-fermentative, non-motile, Gram negative bacillus and formerly known as Flavobacterium odoratus/odoratimimus. It is generally found in soil and water but may be pathogen in patients with underlying disease and immunosuppressed patients. In this study, we describe a 56 year old female patient with underlying diseases who isolated M.odoratus/odoratimimus in urine culture. Keywords : Antibiotic resistance, Myroides, Underlying disease, Urinary tract enfection.
Objective: In this study, we aimed to determine the diagnostic value of the tuberculin skin test (TST) and the QuantiFERON-TB Gold Plus (QFT-Plus) test in the diagnosis of latent tuberculosis infection and to compare the effectiveness of these two tests. Method: One hundred and thirty-four patients aged between 5 and 80 with suspect tuberculosis having QuantiFERON-TB GOLD Plus test and Tuberculin skin test results were included in our study between January 2018 and February 2019. Results: A total of 134 patients aged between 5-80 years were included in the study. In 26 of the QFT-Plus positive cases, TST was positive and in 17 of them TST were negative. TST was positive in 64 patients. Twenty six of TST positive patients were found to be QFT-Plus positive and 38 of them were QFT-Plus negative. The distributional difference was found to be statistically significant. There was no agreement between the QFT-Plus and TDT tests. Conclusion:As a result, considering that TST, which is still used routinely today, has some disadvantages in LTBI research, it is thought that QFT-Plus test can be used as an alternative despite its high cost.
Aims: We aimed to find possible mechanisms and pharmacological effects of cubic Silver nanoparticles (AgNPs). background: Green synthesis is an efficient and eco-friendly method that has been used frequently in silver nanoparticle production in recent years. This method facilitates the production of nanoparticles using various organisms, such as plants, and is also cheaper and easier to apply than the other techniques.

Objectives: This study characterizes cubic AgNPs and describes in detail their anticancer, antimicrobial and anti-Trichomonas vaginalis abilities. Methods: Silver nanoparticles were produced by green synthesis using Juglans regia (walnut) leaf aqueous extract. We validated the formation of AgNPs by UV-vis spectroscopy, FTIR analysis, and SEM micrographs. To determine the pharmacological effects of the AgNPs, we conducted anti-cancer, anti-bacterial, and anti-parasitic activity experiments. method: Silver nanoparticles were produced by green synthesis using Juglans regia (walnut) leaf aqueous extract.

To determine the pharmacological effects of the AgNPs, we conducted anti-cancer, anti-bacterial, and anti-parasitic activity experiments. Results: Cytotoxicity data revealed that AgNPs have cellular inhibitory properties on cancerous MCF7 (breast), HeLa (cervix), C6 (glioma), and HT29 (colorectal) cell lines. Similar results are also obtained with anti-bacterial and anti-Trichomonas vaginalis activity experiments. At certain concentrations, AgNPs displayed stronger anti-bacterial activities than the sulbactam/cefoperazone antibiotic combination in five bacteria species. Furthermore, the 12-h AgNPs treatment exhibited satisfactory anti-Trichomonas vaginalis activity similar to the FDA-approved metronidazole. Conclusion: Consequently, AgNPs produced by the green synthesis method by Juglans regia leaves showed remarkable anti-carcinogenic, anti-bacterial and anti-Trichomonas vaginalis activities. We propose the potential usefulness of green synthesized AgNPs as therapeutics. conclusion: Consequently, AgNPs produced by the green synthesis method by Juglans regia leaves showed remarkable anti-carcinogenic, anti-bacterial and anti-Trichomonas vaginalis activities.

Amaç: Çalışmamızın amacı, iş yerlerindeki çalışma şartlarından, kullanılan malzeme, makine ve tesisattan, insan ve organizasyon hatalarından kaynaklanan tehlikeler dikkate alınarak çalışanların sağlık ve güvenliklerini etkileyebilecek tüm unsurların belirlenerek değerlendirilmesi ve risklerin kontrol altına alınması için bir kılavuz hazırlanmasıdır. Yöntem: Araştırma kapsamında, internet ağ bazlı verilerin yanı sıra belirtilen birimlerde çalışan toplam altı yetkili bireyin (her birimden iki çalışan) ifadelerinden faydalanılmıştır. Risk değerlendirme çalışmasını yapan ekip; işveren, işyerinde sağlık ve güvenlik hizmetini yürüten iş güvenliği uzmanları ile işyeri hekimleri, laboratuvar yöneticileri, çalışmadaki bütün birimleri temsil edecek şekilde belirlenen, mevcut veya muhtemel tehlike kaynakları ile riskler konusunda bilgi sahibi çalışanlardır. Bulgular: Mikrobiyoloji laboratuvarında kişisel koruyucu ekipman kullanımına dikkat edilmemesine bağlı enfeksiyon bulaşma riski ve gürültü riski yüksek risk olarak bulunmuştur. Sterilizasyon ünitesinde tüm riskler orta risk olarak belirlenmiştir. Kan transfüzyon merkezinde yanlış hastaya yanlış kan ürünü verilmesi riski yüksek risk olarak bulunmuştur. Sonuç: Kişisel koruyucu ekipman kullanımına özen gösterilmeli, hasta numunelerinin barkodlandırılmalarına dikkat edilmeli, cihazların bakımı zamanında yapılmalıdır. Yüksek riskli durumlar orta seviyeye düşürülmeli, çalışanlar risk konusunda eğitilmelidir.
