Urinary tract infection is the most common complication after kidney transplant and often is associated with graft loss and mortality. Ultrasonography is the most widely applied imaging modality for diagnosis of complications after kidney transplant. Here, we report a case of a 52-year-old male patient who underwent renal transplant 1 month earlier and who presented with fever, leukocytosis, and leukocyturia. Klebsiella pneumoniae was found in the urine and blood cultures. Ultrasonography revealed multiple, ill-defined margined, hypoechoic areas and cysts within the cortex...

In recent years, besides the widespread occurrence of extended-spectrum β-lactamase (ESBL)- and/or plasmid-mediated AmpC (pAmpC)-producing Enterobacteriaceae in both healthcare and community settings of humans, the third-generation cephalosporin (3GC)-resistant microbes have also been reported from companion animals worldwide. Here, we characterized ESBL- and/or pAmpC-producing Enterobacteriaceae clinical isolates from companion animals. Among the 487 clinical isolates mainly from urine of dogs and cats between May and September 2016, 104 non-repetitive isolates were resistant to the 3GC, and they consisted of 81 of 381 (21...

Currently, the most effective treatment for recurrent urinary tract infections in women is antibiotics. However, the limitation for this treatment is the duration and dosage of antibiotics and the resistance that bacteria develop after a long period of administration. With the aim of identifying mainly novel natural agents with antibacterial activity, the present study was undertaken to investigate the biological and phytochemical properties of extracts from the leaves Taraxacum officinale. The structural identification of compounds present in hexane (Hex) and ethyl acetate (AcOEt) extracts was performed by mass spectrometry (GC-MS) spectroscopic techniques and nuclear magnetic resonance (NMR) with the major compounds corresponding to different sesquiterpene lactones ( α -santonin, glabellin, arborescin, and estafiatin), monoterpene (9,10-dimethyltricycle [4...

Ceftazidime-avibactam was used to treat 77 patients with carbapenem-resistant Enterobacteriaceae (CRE) infections at our center. Thirty- and 90-day survival rates were 81% and 69%, respectively; rates were higher than predicted by SAPS II and SOFA scores at the onset of infection. Clinical success was achieved in 55% of patients, but varied by site of infection. Success rates were lowest for pneumonia (36%) and higher for bacteremia (75%) and urinary tract infections (88%). By multivariate analysis, pneumonia ( P =0...

We present our experience controlling outbreaks of extended-spectrum beta-lactamase (ESBL)-producing bacteria in catheter-associated urinary tract infection and our measures for preventing recurrence of outbreaks. In June 2015, 9 out of 44 hospitalized patients in the same ward had positive urine culture with antibiotic-resistant bacteria, including ESBL-producing Klebsiella pneumoniae belonging to the same cluster, indicating a localized outbreak. The environmental tests detected resistant strains at 1,000 colony forming units/cm2 or more in 8 out of 10 tests...

Background: Extended-spectrum β-lactamase (ESBL)-producing is a significant resistant mechanism to β-lactams in Enterobacteriaceae , especially in Klebsiella pneumoniae . The main objectives of this study were to genetically characterize urinary clinical isolates of K. pneumoniae through the investigating of blaTEM , blaCTX-M and using molecular typing by Enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) method. We also determined the frequency of antibiotic resistance of K...

PURPOSE: To determine changes in antimicrobial resistance and demographics of UTIs in pediatric patients in a single institution over a 6-year period. MATERIALS AND METHODS: The current study examined outpatient urinary isolates from patients aged <18 years. A retrospective cross-sectional analysis of bacteria isolated from children with UTI was performed between 2009 and 2014. The most common bacterial pathogens were determined in the following four age groups: <2 years; 2-5 years; 6-12 years; and 13-17 years...

Vaborbactam (VAB; formerly RPX7009) is a novel beta-lactamase inhibitor based on a cyclic boronic acid pharmacophore with potent inhibitory activity against Ambler class A and C beta-lactamases. It has been co-formulated with meropenem to restore its activity against Klebsiella pneumoniae carbapenemases (KPC). VAB does not inhibit class B or D carbapenemases, nor does it improve the activity of meropenem against multidrug-resistant non-fermenting Gram-negative bacilli, notably Acinetobacter spp. and Pseudomonas aeruginosa...

Background: There is limited data regarding the microbiology of Intensive Care Unit (ICU)-acquired infections, such as ventilator-associated pneumonia (VAP), catheter-associated urinary tract infections (CAUTI), and catheter-related bloodstream infections (CRBSI) from India. Objectives: To explore the microbiology and resistance patterns of ICU-acquired infections and evaluate their outcomes. Materials and Methods: This was a multicenter observational study, conducted by Indian Society of Critical Care Medicine (MOSER study) between August 2011 and October 2012...

Klebsiella pneumoniae is a Gram-negative pathogen that has a large accessory genome of plasmids and chromosomal gene loci. This accessory genome divides K. pneumoniae strains into opportunistic, hypervirulent, and multidrug-resistant groups and separates K. pneumoniae from two closely related species, Klebsiella variicola and Klebsiella quasipneumoniae. Some strains of K. pneumoniae act as opportunistic pathogens, infecting critically ill and immunocompromised patients. These K. pneumoniae are a common cause of health-care associated infections including pneumonia, urinary tract infections (UTIs), and bloodstream infections...

Healthcare-associated infections (HAIs) occurring in patients treated in an intensive care unit (ICU) are serious complications in the treatment process. Aetiological factors of these infections can have an impact on treatment effects, treatment duration and mortality. The aim of the study was to determine the prevalence and microbiological profile of HAIs in patients hospitalized in an ICU over a span of 10 years. The active surveillance method was used to detect HAIs in adult patients who spent over 48 h in a general ICU ward located in southern Poland between 2007 and 2016...

The objective of this study was to analyse the distribution and antimicrobial resistance of bacterial uropathogens isolated from outpatients at Henan Provincial People's Hospital. A total of 1419 samples from 823 newly diagnosed and 596 recurrent UTI outpatients culture positive. Escherichia coli was the most common uropathogen. Compared with the recurrent group, the newly diagnosed group had a higher isolation rate of E. coli and Enterobacter cloacae but a lower isolation rate of Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter spp...

In the past few years, the use of antimicrobial drugs against a wide range of pathogens has increased significantly. This extensive use of drugs has increased the resistance rate in microbial community widely. Molecular techniques for the detection of resistance are more reliable as compared to the conventional phenotypic method. The family Enterobacteriaceae is considered to be an important cause of nosocomial infections due to its predominantly active species such as E. coli, Klebsiella and Pseudomonas. These organisms are mainly involved in causing pneumonia, sepsis, post-surgical and urinary tract infections...

On August 29, 2017, the United States Food and Drug Administration (FDA) approved meropenem/ vaborbactam fixed combination for the treatment of adults with complicated urinary tract infections (cUTI). The decision was based on substantial preclinical and clinical data, including two recent trials involving hundreds of adults with cUTI. Meropenem/ vaborbactam represents a powerful new treatment option to address antibiotic-resistant pathogens, including Klebsiella pneumoniae carbapenemase-producing bacteria...
