Due to tigecycline has shown excellent in vitro activity against most pathogens, tigecycline is selected as one of the candidate drugs for the treatment of multidrug-resistant organisms infections. The purpose of this study was to evaluate the effectiveness and safety of the use of tigecycline for the treatment of patients with BSI. Read More

    Citrobacter braakii bacteremia-induced septic shock after colonoscopy preparation with polyethylene glycol in a critically ill patient: a case report.
    Ann Clin Microbiol Antimicrob 2017 Apr 4;16(1):22. Epub 2017 Apr 4.
    Advanced Emergency and Critical Care Medical Center, Okayama University Hospital, 2-5-1 Kita-ku, Shikata-cho, Okayama-shi, Okayama, 700-8558, Japan.
    Background: Polyethylene glycol (PEG) is widely used for bowel cleaning in preparation for colonoscopy because of its safety. Septic shock after PEG preparation is an extremely rare complication. Herein, we describe a case of septic shock that occurred immediately after colonoscopy preparation with PEG. Read More

    Molecular characterization of penicillin non-susceptible Streptococcus pneumoniae isolated before and after pneumococcal conjugate vaccine implementation in Casablanca, Morocco.
    Ann Clin Microbiol Antimicrob 2017 Apr 4;16(1):23. Epub 2017 Apr 4.
    Laboratoire de Microbiologie, Faculté de Médecine et de Pharmacie, Hassan II University of Casablanca, B.P 5696, Casablanca, Morocco.
    Background: Streptococcus pneumoniae is a major cause of morbidity and mortality worldwide, especially among children and the elderly. The ability to effectively treat pneumococcal infection has been compromised due to the acquisition of antibiotic resistance, particularly to β-lactam drugs. This study aimed to describe the prevalence and molecular evolution of penicillin non-susceptible S. Read More

    Extended-spectrum beta-lactamase-producing Pseudomonas aeruginosa in camel in Egypt: potential human hazard.
    Ann Clin Microbiol Antimicrob 2017 Mar 31;16(1):21. Epub 2017 Mar 31.
    Department of Microbiology and Immunology, National Research Centre, Giza, Egypt.
    Background: The rapid increase of extended-spectrum beta-lactamase (ESBL) producing bacteria are a potential health hazard. Development of antimicrobial resistance in animal pathogens has serious implications for human health, especially when such strains could be transmitted to human. In this study, the antimicrobial resistance due to ESBL producing Pseudomonas aeruginosa in the camel meat was investigated. Read More

    Antibiotic consumption in laboratory confirmed vs. non-confirmed bloodstream infections among very low birth weight neonates in Poland.
    Ann Clin Microbiol Antimicrob 2017 Mar 31;16(1):20. Epub 2017 Mar 31.
    Chair of Microbiology, Jagiellonian University Medical College, 18 Czysta Street, 31-121, Krakow, Poland.
    Background: Newborns are a population in which antibiotic consumption is extremely high. Targeted antibiotic therapy should help to reduce antibiotics consumption. The aim of this study was an assessment of antibiotic usage in bloodstream infections treatment in the Polish Neonatology Surveillance Network (PNSN) and determining the possibility of applying this kind of data in infection control, especially for the evaluation of standard methods of microbiological diagnostics.

    Killing of Serratia marcescens biofilms with chloramphenicol.
    Ann Clin Microbiol Antimicrob 2017 Mar 29;16(1):19. Epub 2017 Mar 29.
    Department of Microbiology, The University of Alabama at Birmingham, Birmingham, AL, USA.
    Serratia marcescens is a Gram-negative bacterium with proven resistance to multiple antibiotics and causative of catheter-associated infections. Bacterial colonization of catheters mainly involves the formation of biofilm. The objectives of this study were to explore the susceptibility of S. Read More

    Systematic review and meta-analysis of mortality of patients infected with carbapenem-resistant Klebsiella pneumoniae.
    Ann Clin Microbiol Antimicrob 2017 Mar 29;16(1):18. Epub 2017 Mar 29.
    Department of Laboratory Medicine, Anhui Provincial Hospital, Anhui Medical University, Hefei, 230001, Anhui, China.
    Purpose: Carbapenem resistant K. pneumoniae (CRKP) has aroused widespread attention owing to its very limited therapeutic options, and this strain has increased rapidly in recent years. Although it is accepted that drug resistance is associated with increased mortality in general, but some other studies found no such relationship. Read More

    Activity of AMP2041 against human and animal multidrug resistant Pseudomonas aeruginosa clinical isolates.
    Ann Clin Microbiol Antimicrob 2017 Mar 23;16(1):17. Epub 2017 Mar 23.
    Department of Veterinary Science, University of Parma, Via del Taglio 10, 43126, Parma, Italy.
    Background: Antimicrobial resistance is a growing threat to public health. Pseudomonas aeruginosa is a relevant pathogen causing human and animal infections, frequently displaying high levels of resistance to commonly used antimicrobials. The increasing difficulty to develop new effective antibiotics have discouraged investment in this area and only a few new antibiotics are currently under development. Read More
