ÖZETÜriner sistem infeksiyonlarının (ÜSİ) In conclusion, in our study E.coli is the most detected microorganism and for these strains nitrofurantoin, quinolones and aminoglycosides' resistance rates were below 20 %. Therefore we think that these antibiotics may be used for empirical therapy. But because of antibiotics' negative effects and the high ESBL positivity in E.coli strains and the increased resistance rates for the antibiotics in these strains, it seems necessary to perform culture and antibiotic susceptibility testing before therapy. SUMMARY The Evaluation of Resistance Rates to Various Antibiotics and Extended Spectrum Beta-lactamase Positivity of Esherichia coli and Klebsiella spp. Strains Isolated from Outpatients with Urinary Tract Infection Most of the urinary tract infections are uncomplicated and community acquired. Escherichia coli and less frequently Klebsiella spp. strains are known to be the most frequent microorganisms that cause urinary tract infections. Development of antimicrobial resistance in these bacteria is an important problem for the world. The most important mechanism for antibacterial resistance ise production of extended spectrum beta-lactamases (ESBL). In this study antimicrobial resistance rates of E.coli and Klebsiella spp. strains isolated from urine cultures and impact of the ESBL
ÖZAmaç: Bu çalışmada, bağırsak parazitlerinin prevalansı ile bazı hijyen alışkanlıkları ve sosyo-demografik özelliklerinin ilişkisinin araştırılması amaç-lanmıştır. Yöntemler: Çalışmanın ilk yılı parazitoz prevalansı ve anketlerle hijyen bilgi düzeyleri ölçülmüş, ikinci yıl kontrol ve müdahale grubu belirlenmiştir. Müdahale gruplarına eğitim verilmiştir. Üçüncü yıl bu kontrol ve müdahale gruplarında parazitoz ve hijyen konusundaki gelişme araştırılmış, sonuçlar karşılaştırılmıştır. İlk olarak, toplam 826 çocuğa ulaşılmış ancak öğrencilere ait 523 dışkı örneği ve 540 selofan bant örneği incelenebilmiştir. Dışkı ör-neklerine direk bakı, %0,85'lik NaCl, formol-eter konsantrasyon işlemi sonrasında lugol, kinyoun asit-fast ve trikrom boyama yöntemleri uygulanmıştır. Bulgular: İncelenen örneklerde 87 (% 16,1) Enterobius vermicularis, 79 (% 15,1) Giardia intestinalis, 73 (% 13,9) patojen olmayan çeşitli parazitler, 1 (% 0,19) Ascaris lumbricoides, 1 (% 0,19) Hymenolepis nana, saptanmıştır. Bulunan sonuçlar anket cevapları ile birlikte analiz edilmiştir. Dışkılama sonrası ellerini yıkamayan çocuklarda G. intestinalis yüksek oranda pozitif saptanmıştır. Ayrıca anne-baba eğitim durumu, ailenin gelir düzeyi ve baba mesleği ile bağırsak parazitleri varlığının ilişkili olduğu bulunmuştur. Üçüncü aşamada müdahale grubunda 68 (45,6%), kontrol grubunda 81 (54,4%) toplam 149 çocuk incelenmiştir. Eğitim sonrası müdahale grubunda giardiyazis ve enterobiazis olgu sayılarında belirgin azalma görülmüştür. Sonuç: Paraziter hastalıkların bu bölgede önemli bir halk sağlığı sorunu olduğu görülmüştür. Hijyen konusunda yapılacak eğitimlerin paraziter hastalıkları önlemesi açısından faydalı olacağı düşünülmüştür. ( ABSTRACT Objective: In this study, the prevalence of intestinal parasites and its relationship with some hygiene habits and socio-demographic characteristics of students in Yığılca were investigated. Methods: This study was conducted in three parts. Firstly, the prevalence of parasitic diseases was measured, and questionnaires about the level of knowledge of hygiene were administered. Secondly, control and intervention groups were determined. Lastly, some education and training courses were organized and provided to the intervention group, including parents and children, about the prevention of parasitic diseases and habits of cleaning.Results: In this study, 540 cellophane tapes and 523 stool samples were studied. Among the samples analyzed, 87 (16.1%) with Enterobius vermicularis, 79 (15.1%) with Giardia intestinalis, 73 (13.9%) with various non-pathogenic parasites, 1 (0.19%) with Ascaris lumbricoides, and 1 (0.19%) with Hymenolepis nana were found. G. intestinalis was highly positive among the children who do not wash their hands after defecation. Also, some intestinal parasites were found to be related to the socio-demographic characteristics of families; parental education, family income, and father's profession were found to be associated with the presence of intestinal parasites. After training, the intervention group sho...
Aim: Early diagnosis of bacterial infections is crucial in planning treatment. Thus, it is important to determine the gram staining property of bacteria as well as the presence of bacterial infection. The acute bacterial infection leads to morphological changes in neutrophils. In this study, we investigated the use of neutrophil volume, conductivity and lightscattering (VCS) parameters as potential indicators for rapid diagnosis of bacterial infections, and to distinguish infections caused by gram-positive and gram-negative bacteria. Material and Methods: Patients with urinary tract infections, pneumonia, wound site infections and sepsis were included. The control group comprised patients without bacterial infections. The blood samples of the patients were examined for white blood cell and neutrophil counts; neutrophil VCS parameters were determined using a Coulter Analyzer. The VITEK 2 Compact System was used to detect microbial growth. Results:The blood sample data of 472 patients sent to our laboratory for Complete Blood Count analyses from various clinics were analyzed in this study. A total of 370 samples showed significant growth in their bacteriological culturing, whereas the remaining 102 samples showed no growth. For the detection of bacterial growth, the specificities of median neutrophil volume (MNV) and median neutrophil conductivity (MNC) were found to be 96% and 99%, respectively. In addition, median neutrophil light scattering (MNS) was higher in the gram-negative bacterial group than in the grampositive bacterial group. Conclusion:The use of neutrophil VCS parameters is an effective and time-saving method to identify bacterial infections and distinguish between gram-positive and gram-negative bacterial infections.
ÖZET Nonfermentatif Gram negatif bakterilerin yol açtığı infeksiyonlarda tedavi sorun oluşturmaktadır. Karbapenemlere karşı gelişen dirençte en önemli mekanizma metallo-beta-laktamaz (MBL) üretimidir. Son yıllarda MBL üretimi nedeniyle ortaya çıkan karbapenem direnç Anahtar sözcükler: Acinetobacter baumannii, metallo-beta-laktamaz, Pseudomonas aeruginosa SUMMARY Investigation of Metallo-Beta-Lactamase Activity by Various Phenotypic Methods in Non-Fermentative Gram Negative Bacteria Treatment of infections caused by non-fermentative Gram-negative bacteria (NFGNB) is a problem. The most important mechanism for developing resistance against carbapenems is metallo-beta-lactamase (MBL) production. This study was performed to investigate the prevalence of MBL in NFGNB which cause infections in our hospital and to compare different phenotypic methods for detecting the presence of MBL. A total of 86 isolates which are intermediately resistant or/ resistant to imipenem, consisting of 50 Pseudomonas aeruginosa and 36 Acinetobacter baumannii, which were isolated at Düzce University Hospital Microbiology Laboratory from various clinics were included the study. Antimicrobial susceptibility testing of the isolates were performed by Kirby-Bauer disk diffusion method and VITEK2 automated system. Presence of MBL was investigated by four different phenotypic methods (Double Disk Synergy Test-DDST, the Combined Disk Test-CDT, modified Hodge test-MHT, E-test (bioMerieux, France).The majority of the samples (44%) were deep tracheal aspirate specimens. In addition, 46.5 % of the samples were sent from intensive care units. In our study, MBL positivity was detected as 34 %, 55 %, 45 %, 48 % by using DDST, CDT, respectively
