Klebsiella pneumoniae (K. pneumoniae) is a frequent pathogen causing nosocomial infections and outbreaks. We developed a multiple cross displacement amplification (MCDA) assay for the detection of K. pneumoniae, which can get the positive results within 40 minutes' isothermal amplification. Gold-nanoparticle lateral flow biosensor (LFB) and colorimetric indicators were used for the rapid readouts of MCDA amplification. The detection limit of this assay was 100 fg per reaction at 65°C, which was confirmed to be the optimal amplification temperature according to the real time turbidimeters...

Carbapenem resistant Klebsiella pneumoniae (CRKP) nosocomial infection increased rapidly in recent years. By far, the anti-infection drugs for CRKP infection are limited. Tigecycline is one of the last resort treatments for CRKP infections. In this study, curative effect of tigecycline therapy was monitored in a 59-year-old male patient infected with KPC-producing K. pneumoniae. Consecutive clonal consistent K. pneumoniae isolates were cultured during tigecycline treatment. Whole genome sequencing of the isolates was performed, and bioinformatics analysis was further performed...

Acinetobacter lwoffii, a serious human pathogen, has been identified as a cause of nosocomial infections such as bacteremia, pneumonia and meningitis. There are only a few studies reporting A. lwoffii as a pathogen of fish. During 2016 and 2017, six bacterial strains, isolated from diseased fish of the Schizothorax genus, were identified as A. lwoffii by morphology, biochemical tests, 16S rDNA and gyrB gene sequencing analysis. One of these isolates was selected for experimental infection of Sclizothorax prenanti, Schizothorax davidi and Schizothorax wangchiachii, to confirm its pathogenicity...

Nosocomial infections are caused by ESKAPE (E. faecium, S. aureus, K. pneumoniae, A. baumannii, P. aeruginosa, and E. cloacae) pathogens, and their co-existence is associated with their ability to survive in the hospital setup. They may produce molecules, which helps in the better survival of one ESKAPE pathogens over other. We have identified all secondary metabolite gene clusters in six ESKAPE pathogens and predicted antimicrobial and anti-biofilm properties of their product secondary metabolites. To validate our model, we have taken the secondary metabolites of ESKAPE pathogens and studied their interaction with diguanylate cyclase (involved in quorum sensing) and biofilm-associated protein (involved in biofilm formation) of Acinetobacter baumannii...

This review deals with various microbiological activities of ionic liquids, which constitute the first anti-infective defense against multi-drug-resistant bacteria-with a particular emphasis placed on medicine and pharmacology. The quoted data on the biological activity of ionic liquids including their antimicrobial properties (depending on the type of a cation or an anion) and are discussed in view of possible applications in nosocomial infections. Dedicated attention is given to finding infections with the Klebsiella pneumoniae New Delhi strain, Acinetobacter baumannii , and Enterococcus species, which are responsible for the induction of antibiotic resistance in intensive care units...

Ceftazidime-avibactam is a novel β-lactam/β-lactamase inhibitor combination for the treatment of serious infections caused by resistant gram-negative pathogens. Population pharmacokinetic (PopPK) models were built to incorporate pharmacokinetic (PK) data from five phase III trials in patients with complicated intra-abdominal infection (cIAI), complicated urinary tract infection (cUTI), or nosocomial (including ventilator-associated) pneumonia. Ceftazidime and avibactam pharmacokinetics were well-described by two-compartment disposition models, with creatinine clearance (CrCL) the key covariate determining clearance variability...

Infectious disease caused by pathogenic bacteria continues to be the primary challenge to humanity. Antimicrobial resistance and microbial biofilm formation in part, lead to treatment failures. The formation of biofilms by nosocomial pathogens such as Staphylococcus aureus ( S. aureus ), Pseudomonas aeruginosa ( P. aeruginosa ), and Klebsiella pneumoniae ( K. pneumoniae ) on medical devices and on the surfaces of infected sites bring additional hurdles to existing therapies. In this review, we discuss the challenges encountered by conventional treatment strategies in the clinic...

The expected excess length-of-stay is an established concept to assess the health and economic impact of nosocomial, that is, hospital-acquired infections such as ventilation-acquired pneumonia in intensive care. Estimation must account for the timing of infection as in a multistate perspective, because common retrospective comparisons yield inflated estimates due to time-dependent bias. Since occurrence of ventilation-acquired pneumonia is closely linked to ventilation status, we suggest a multistate model incorporating time-dependent mechanical ventilation as additional states...

Imipenem and meropenem are the recommended antipseudomonal carbapenems for nosocomial pneumonia per clinical practice guidelines. However, these agents have a relatively broader spectrum of activity than other antibiotics and need to be reserved. Carbapenems might cause higher rate of superinfection. The aim of this study was to compare the rate of superinfection between patients who received imipenem or meropenem versus those who received non-carbapenem treatment. PubMed, EMBASE, Cochrane Library databases and two trial registries were searched for relevant randomized controlled trials of hospitalized adults with pneumonia through February 24, 2017 without date or language restrictions...
