    Antibiotic resistance of streptococcus pneumoniae and haemophilus influenzae isolated from respiratory tract specimens
    (2016) Aliskan, Hikmet Eda; Colakoglu, Sule; Gocmen, Julide Sedef
    Purpose: Streptococcus pneumoniae and Haemophilus influenzae are two of the major pathogens in respiratory infections, treatment is usually started empirically. The aim of this study was to detect in vitro resistance rates of S. pneumoniae and H. influenzae strains isolated from different lower respiratory clinical samples to the antibotics which are used for therapy of infections due to these pathogens. Material and Methods: Seventy seven S. pneumoniae and 117 H. influenzae strains, isolated from patients were included in the study. S. pneumoniae isolates which gave an inhibition zone diameter of > 20 mm for oxacillin were considered susceptible for penicilin. For the isolates which had an oxacillin zone diameter of <20 mm, MIC values of penicillin and cefotaxime were obtained by E-test method (bioMerieux, Marcy-l'Etoile, France). Results: Of 77 S. pneumoniae isolates, 24.6 % were resistant (MIC> 2 mg/l) and 31.1 % were intermediately resistant to parenteral penicillin. Resistance rates to antibiotics were as follows: erythromycin 40 %, trimethoprim/sulphametoxazole (TMP/SMX) 54.5 % and ofloxacin 6.4%. beta-lactamases were detected in 15.6% of the H. influenzae isolates by nitrocefin positivity. Conclusion: H. influenzae strains (8.6%) were identified as beta-lactamase negative ampicillin resistant (BLNAR) strains. Resistance rates for other antibiotics were as follows: ampicillin 28.6%, cefaclor 36.5%, cefuroxime 30.1%, clarithromycin 9.6%, cloramphenicol 7% and TMP-SMX 43.9%.

    HUMAN PAPILLOMA VIRUS (HPV) PREVALENCE AND GENOTYPE DISTRIBUTION
    (2017) Bolat, Filiz Aka; Colakoglu, Sule; Coban, Gonca; 0000-0002-3285-5519; AAI-9974-2021
    Assessment of Human papillomavirus (HPV) prevalence and genotype distribution is important for monitoring the impact of prophylactic HPV vaccination. This study aimed to demonstrate the HPV prevalence and type distribution in women from the Baskent University Adana Dr. Turgut Noyan Practice and Research Center. Cervical specimens from 268 women aged 22-68 years were collected between April 2014 and November 2015. Histopathological examinations were performed for 146 women. HPV DNA was amplified by PCR and HPV and genotyping was undertaken using the Roche (R) linear array detection kit. In total. 124 out of 268eligible samples (46.31%) tested positive for HPV. with the majority of these [84/124 (67.7%1] having high-risk (HR) HPV infection: 20.9% were positive for HPV16 (n=261, and 4% for HPV18 (n=5) HPV type-specific prevalence was 63.9% 53.39 and 80% among cervical intraepithelial neoplasias (CIN) Grades respectively. The coverage of other HR-HPV genotypes apart from 16. included HPV31. 45. 51, 53, and 56 in high-grade cervical lesions. In conclusion, HPV-16 was identified as the main HPV genotype associated with cervical disease in our hospital. The study reports the identification of high-and low-risk HPV genotypes as well as the prevalence of multiple HPV infections.
