[Investigation of Virulence Genes and Carbapenem Resistance Genes in Hypervirulent and Classical Isolates of Klebsiella pneumoniae Isolated from Various Clinical Specimens].

Klebsiella pneumoniae is a global pathogen that can cause hospital-acquired and community-acquired infections and is known for its resistance to antibiotics. The pathotype, which is defined as hypervirulent K.pneumoniae (hvKp) is more lethal than classical K.

Transcriptomic and fatty acid analyses of Neochloris aquatica grown under different nitrogen concentration.

In this study, we characterized the fatty acid production in Neochloris aquatica at transcriptomics and biochemical levels under limiting, normal, and excess nitrate concentrations in different growth phases. At the stationary phase, N. aquatica mainly produced saturated fatty acids such as stearic acid under the limiting nitrate concentration, which is suitable for biodiesel production.

Efficacy of loading dose of colistin in Acinetobacter baumannii ventilator-associated pneumonia.

Colistin loading dose (LD) has been postulated as an advance in therapy. The clinical, microbiological effectiveness and nephrotoxicity of adding an LD to systemic colistin in ventilator-associated pneumonia (VAP) caused by multidrug-resistant (MDR) Acinetobacter baumannii remain unknown. In this quasi experimental study, the efficacy, outcomes and nephrotoxicity in 30 adults who received intravenous colistin with LD for MDR A.

Enhancement of the lipid productivity and fatty acid methyl ester profile of Chlorella vulgaris by two rounds of mutagenesis.

In this study, we applied a second round of random mutagenesis using ethyl methanesulfonate to further increase the lipid productivity of a Chlorella vulgaris mutant strain. We generated a mutant (UV715-EMS25) with a lipid content and biomass that were respectively 67% and 35% higher than those of the wild type (WT). The highest achieved lipid productivity in UV715-EMS25 was 91 mg L day.

An outbreak of bloodstream infection due to extensively resistant Acinetobacter baumannii among neonates.

Background: Extensively resistant Acinetobacter baumannii has emerged and spread worldwide as a significant cause of health care-associated infections and outbreaks. It also causes life-threatening infections among neonates, including bacteremia. The aim of this study was to investigate an outbreak of A baumannii bacteremia (ABB) among neonates.

[Evaluation of virulence factors in enterococcus species].

Enterococci have recently become important due to their increased isolation rates in community-based and nosocomial infections and resistance to many antibiotics, including glycopeptides. The aim of this study was to evaluate the antimicrobial susceptible patterns and virulence factors of various clinical specimens; urine (n= 149), blood (n= 38), wound (n= 17), stool (n= 13), and other (n= 12) with a total of 229 enterococci including 138 E.faecalis and 91 E.

Is surveillance for colonization of carbapenem-resistant gram-negative bacteria important in adult bone marrow transplantation units?

Background: The aim of this study was to investigate the rate of carbapenem-resistant gram-negative bacilli (CRGNB) colonization and to analyze the risk factors associated with CRGNB colonization.

Methods: This prospective study was conducted in adult patients hospitalized in hematopoietic stem cell transplantation (HSCT) units over a period of 8 months. Rectal swab samples were obtained from each participant every Monday, and patients CRGNB positive on admission were excluded.

Epidemiology and cost implications of candidemia, a 6-year analysis from a developing country.

Surveillance of candidemia is essential to monitor trends in species distribution and change in the incidence and antifungal resistance. In this study, we aimed to investigate prevalence, resistance rates, antifungal utilization and costs. A 6-year retrospective analysis of the data belonging to patients with candidemia hospitalized between 2010 and 2016 was performed.

Glu-370 in the large subunit influences the substrate binding, allosteric, and heat stability properties of potato ADP-glucose pyrophosphorylase.

ADP-glucose pyrophosphorylase (AGPase) is a key allosteric enzyme in plant starch biosynthesis. Plant AGPase is a heterotetrameric enzyme that consists of large (LS) and small subunits (SS), which are encoded by two different genes. In this study, we showed that the conversion of Glu to Gly at position 370 in the LS of AGPase alters the heterotetrameric stability along with the binding properties of substrate and effectors of the enzyme.

The effect of melatonin on bacterial translocation following ischemia/reperfusion injury in a rat model of superior mesenteric artery occlusion.

Background: Acute mesenteric ischemia is a life-threatening vascular emergency resulting in tissue destruction due to ischemia-reperfusion injury. Melatonin, the primary hormone of the pineal gland, is a powerful scavenger of reactive oxygen species (ROS), including the hydroxyl and peroxyl radicals, as well as singlet oxygen, and nitric oxide. In this study, we aimed to investigate whether melatonin prevents harmful effects of superior mesenteric ischemia-reperfusion on intestinal tissues in rats.

Introduction: The widespread use of tigecycline raises the question of increasing infection rates of Pseudomonas aeruginosa (PA) in ICUs which are not affected by this antibiotic.

Objective: The aim of this study was to determine if treatment with tigecycline is a risk factor for PA infection in ICU patients.

Methodology: A retrospective and observational study was conducted at Erciyes University Hospital, Turkey, between 2008 and 2010.

[Investigation of macrolide, lincosamide and streptogramin B resistance in Staphylococcus aureus strains isolated from clinical samples by phenotypical and genotypical methods].

Staphylococcus aureus is one of the most common cause of both community and healthcare-associated infections. As staphylococci have developed resistance to various antibiotics, initially to penicillins then to methicillin and glycopeptides and have the ability to cause epidemics, they continue to be a major problem from past to present. Methicillin resistance gave rise to the use of alternative antibiotics such as macrolides, however worldwide development of macrolide resistance limited the use of these antibiotics.

Economic evaluation of appropriate duration of antibiotic prophylaxis for prevention of neurosurgical infections in a middle-income country.

Background: Preoperative antibiotic prophylaxis is one of the preventive measures for surgical site infections (SSIs). Very little data about the cost effectiveness of the appropriate duration of antibiotic prophylaxis in low- and middle-income countries are available. We aim to assess the cost effectiveness of the use of antibiotic prophylaxis for <24 hours to prevent neurosurgical infections in a middle-income country, Turkey.
