The ZnO thin films have been prepared by spin coating followed by annealing at different temperatures like 300°C, 350°C, 400°C, 450°C, 500°C & 550°C and ZnO nanoparticles have been used for photocatalytic and antibacterial applications. The morphological investigation and phase analysis of synthesized thin films well characterized by X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Photoluminescence (PL), Transmission Electron Microscopy (TEM) and Raman studies. The luminescence peaks detected in the noticeable region between 350nm to 550nm for all synthesized nanosamples are associated to the existence of defects of oxygen sites...

BACKGROUND: Ureteral stent insertion during kidney transplantation is a matter of debate. Stenting has been proven to reduce the risk of surgical complications. In addition, it has been reported to increase risks such as urinary tract infections especially after operation. Ureteral stent colonization (USC) is known to play a role in the pathogenesis of stent related-infections. The aim of this study was (1) to assess the frequency of USC and values of urine cultures in identifying colonizing bacteria; (2) to assess the importance of indwelling time for USC in live-donor renal transplant recipients; and (3) to evaluate the biomarker role of neutrophil-to-lymphocyte ratio (NLR) on USC...

In this study, optimization conditions for cyanide biodegradation by Klebsiella pneumoniae strain were determined to be 25 °C, pH=7 and 150 rpm at the concentration of 0.5 mM potassium cyanide in the medium. Additionally, it was found that K. pneumoniae strain is not only able to degrade potassium cyanide, but also to degrade potassium hexacyanoferrate(II) trihydrate and sodium ferrocyanide decahydrate with the efficiencies of 85 and 87.5%, respectively. Furthermore, this strain degraded potassium cyanide in the presence of different ions such as magnesium, nickel, cobalt, iron, chromium, arsenic and zinc, in variable concentrations (0...

INTRODUCTION: Klebsiella pneumoniae is one of the main opportunistic pathogens which can cause different types of infections. Production of beta-lactamases like AmpC and ESBL mostly lead to beta-lactam resistance in these Gram-Negative bacteria. The aim of this study was the detection of AmpC-producing K. pneumoniae in clinical isolates. MATERIALS AND METHODS: Three hundred and three isolates of K. pneumoniae were identified. Double disc method including cefoxitin with cefepime and using boronic acid with cloxacillin were performed as two phenotypic methods for detection of AmpC...

BACKGROUND: Bacterial pathogens isolated from dacryocystitis patients are diverse and complex in terms of their distribution, prevalence, and antimicrobial susceptibility pattern. The clinical importance of microbial causes of dacryocystitis and pattern of drug resistance has not been reported in northwest Ethiopia. Moreover, the management of dacryocystitis is based on only clinical observation Therefore, this study attempted to identify and define clinical and microbiological characteristics of microbial agents of dacryocystitis and its antibiotic susceptibility patterns...

Mycoplasma pneumoniae is a major pathogen causing community-acquired pneumoniae (CAP), which is generally treated with macrolides. In recent years, however, although macrolide-resistant M. pneumoniae has been reported frequently, particularly in China, very little is known about the prevalence of macrolide-resistant M. pneumoniae infection in adults. In this study, we survey the macrolide-resistant M. pneumoniae in adults in Zhejiang province and characterize the mechanisms of resistance to macrolide. Six hundred fifty throat swab samples were collected from adult patients with CAP from January 2012 to August 2014...

The purpose of this study was to evaluate the postmortem distributions of procalcitonin (PCT), C-reactive protein (CRP), soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and soluble interleukin-2 receptor (sIL-2R) levels in postmortem serum from femoral blood, pericardial fluid and pleural fluid in a series of sepsis-related fatalities (12 subjects) and control cases (20 subjects) that underwent medico-legal investigations. Our aim was to assess the diagnostic potential of the results obtained from pericardial and pleural fluid analysis in identifying sepsis-related deaths...

BACKGROUND: To evaluate the predictive powers of serum surfactant protein D (SP-D) levels as a biomarker of lung damage in tuberculosis and lung diseases. METHODS: This study prospectively included 137 subjects who applied to our hospital. We measured serum SP-D levels from patients with active tuberculosis (TB) (n = 35), chronic obstructive disease (COPD) patients experiencing acute exacerbations (n = 30), patients with pneumonia (n = 45), and control subjects (n = 27)...

BACKGROUND: This study was conducted to know the rate of prevalence of community acquired UTI infections in both males and females, Assam, North-East India. MATERIALS AND METHODS: A 50 μl of urine sample from each of the subjects was streaked on cystine lactose electrolyte-deficient agar medium. The plates were incubated overnight at 37°C. Pure, isolated colonies of each type was separately cultured and characterized. The susceptibility of the clinical isolates to routinely prescribed antibiotics in the hospital was performed against various antibiotics...

Although mucocutaneous candidiasis is a common infection in renal transplant recipients, disseminated candidiasis is rare. Candida pnemonia causing miliary mottling on X-ray chest with the central nervous system involvement is still rarer. We report an unusual case with disseminated candidiasis that presented 18 years after renal transplantation and improved on conventional antifungal therapy; the relevant literature is reviewed.

A series of 36 synthetic antimicrobial peptides containing unnatural amino acids were screened to determine their effectiveness to treat Enterococcus faecium, Staphylococcus aureus, Klebsiella pnemoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species (ESKAPE) pathogens, which are known to commonly infect chronic wounds. The primary amino acid sequences of these peptides incorporate either three or six dipeptide units consisting of the unnatural amino acids Tetrahydroisoquinolinecarboxylic acid (Tic) and Octahydroindolecarboxylic acid (Oic)...

We report the identification of New Delhi metallo-betalactamase 1 (NDM-1)-producing Klebsiella pnemoniae in Ireland. The organism was resistant to multiple antibiotic classes, including carbapenems, and PCR and sequencing confirmed the presence of the blaNDM-1 gene, carried on a 98 kb plasmid. The organism was isolated from an infant, who was born in India and moved to Ireland at the age of four months. This is the first reported isolation of an NDM-1-producing Enterobacteriaceae strain in Ireland.

The Stevens-Johnson syndrome (SJS) classically involves a rash, conjunctivitis and mucositis. We describe the case of a young adult male with isolated mucositis and conjunctivitis . Previous rare reports of severe SJS like syndromes without a rash are confined to children, usually with mycoplasma pnemoniae infection.(1) Terminology for this syndrome includes - "Stevens-Johnson Syndrome without skin lesions", or "Atypical Stevens - Johnson Syndrome".(2) This case highlights the importance of maintaining an open mind when a "full house" of clinical features is absent...

The essential oil of the fruit of Illicium griffithii Hook f. et Thoms. was extracted using Clevenger's apparatus. Forty-one compounds were characterized by gas chromatography-mass spectroscopy (GC-MS). 4-Methyl-6-(2-propenyl)-1,3-benzodioxole was characterized as the major constituent, followed by linalool amongst the volatile constituents. The essential oil was found to be effective against Aspergillus niger, Penicillium spp. and Saccharomyces cerevisiae and possessed considerable activity against Staphylococcus aureus and was inactive against Klebsiella pnemoniae, Pseudomonas aureginosae, Proteus vulgaris and Escherichia coli...
