BACKGROUND Severe cases of infections caused by Raoultella planticola are constantly being reported from all over the world with the increase in drug-resistance patterns. In this study, we retrospectively evaluated the clinical characteristics of R. planticola infections with patients' demographics and antimicrobial susceptibilities of the R. planticola(More)
OBJECTIVES Tonsil and adenoid core cultures were compared and beta-lactamase producing bacteria were determined in patients with chronic adenotonsillitis. PATIENTS AND METHODS Thirty-two patients (21 boys, 11 girls; mean age 5 years) with chronic adenotonsillitis underwent elective adenotonsillectomy. The core swaps of tonsil and adenoid tissues were(More)
BACKGROUND Blood cultures are the main diagnostic laboratory tool to detect bloodstream infections. Many clinical microbiology laboratories utilize automated blood culture systems to isolate infectious agents from blood samples. The diagnostic performance and time-to-detection values of the novel automated blood culture system, DLBt112TM (DL), was compared(More)
Morganella morganii is rarely isolated from nosocomial infections. However, postoperative infections due to Morganella spp. were documented in literature and eye involvements of the infections usually result in severe sequels. We present a severe case infection, which was caused by M. morganii subsp. morganii, firstly appearing as conjunctivitis and(More)
AIM To investigate and compare the radiographic size of acute apical abscess lesions for the presence of Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus-6 (HHV-6) and human papillomaviruses (HPV) DNA by means of the real-time polymerase chain reaction (PCR) method. METHODOLOGY According to the radiographic size of acute apical(More)
BACKGROUND Automated blood culture systems are routinely used in microbiology laboratories to isolate bacteria and fungi causing bloodstream infections. A novel automated blood culture system, DL-Bt112TM (DL) was compared with the BACTEC 9050TM (BCT) and BacT/Alert 3DTM (B3D) systems for time-to-detection (TTD) using 10 different clinical bacteria that(More)
OBJECTIVE The purpose of this study is to compare transient bacteriemia ratios between cold dissection tonsillectomy and bipolar cauterizing tonsillectomy, and also to analyze the bacteria detected with superficial/central tonsillar cultures. METHODS A total of 86 patients that were grouped as 46 patients of cold dissection tonsillectomy and 40 patients(More)
BACKGROUND The prognostic value of blood culture testing in the diagnosis of bacteremia is limited by contamination. OBJECTIVES In this multicenter study, the aim was to evaluate the contamination rates of blood cultures as well as the parameters that affect the culture results. MATERIALS AND METHODS Sample collection practices and culture data obtained(More)
INTRODUCTION The Streptococcus anginosus group of bacteria are low-virulence bacteria existing as commensals in the oral flora and gastrointestinal tracts of humans. S. anginosus may spread to the blood in individuals with poor oral hygiene in cases of oral infections, such as gingivitis and tooth abscesses, that develop following the loss of mucosal unity.(More)
The goal of this analysis was to examine the association between age-specific hepatitis A virus (HAV) seroprevalence rates and various socioeconomic indicators within the Middle East and North Africa (MENA) region. We conducted a systematic review of all recently published studies on HAV conducted in the MENA region and identified the highest quality(More)
