Direct identification of pathogens in urine using a specific MALDI-TOF spectra database.

J Clin Microbiol 2019 Jan 30. Epub 2019 Jan 30.

IHU-Méditerranée Infection, Marseille, France

Urinary tract infections are among the most common reasons for antimicrobial treatment, early diagnosis could have a significant impact by enabling rapid administration of the adapted antibiotic and preventing complications. The current delay between sample receipt and pathogen identification is about 24-48 hours, which could be significantly shortened by an accurate direct method. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) is already used for the identification of pathogens in clinical laboratories and constitutes a promising tool for direct diagnosis.

Clin Microbiol Rev 2019 Mar 30;32(2). Epub 2019 Jan 30.

Department of Medicine, Rhode Island Hospital, Warren Alpert Medical School of Brown University, Providence, Rhode Island, USA.

SUMMARYThe genus comprises a ubiquitous group of Gram-positive bacteria that are of great relevance to human health for their role as major causative agents of health care-associated infections. The enterococci are resilient and versatile species able to survive under harsh conditions, making them well adapted to the health care environment. Two species cause the majority of enterococcal infections: and Both species demonstrate intrinsic resistance to common antibiotics, such as virtually all cephalosporins, aminoglycosides, clindamycin, and trimethoprim-sulfamethoxazole.

Occurrence of enterococci harbouring clinically important antibiotic resistance genes in the aquatic environment in Gauteng, South Africa.

Environ Pollut 2019 Feb 19;245:1041-1049. Epub 2018 Nov 19.

Department of Medical Microbiology, Faculty of Health Sciences, University of Pretoria, Pretoria, South Africa; National Health Laboratory Service, Tshwane Academic Division, Pretoria, South Africa. Electronic address:

The development of antibiotic resistance and dissemination of its determinants is an emerging public health problem as it compromises treatment options of infections that were, until recently, treatable. Investigation of outbreaks of vancomycin resistant enterococci (VRE) suggests that the environment serves as a significant reservoir for antibiotic resistance genes (ARGs). However, there is a paucity of data regarding the presence of ARGs in the water sources in South Africa. Read More

Asymptomatic bacteriuria in recurrent UTI - to treat or not to treat.

GMS Infect Dis 2017 28;5:Doc09. Epub 2017 Dec 28.

Department of Translational Research and New Technologies, University of Pisa, Italy.

Asymptomatic bacteriuria (ABU) is a common clinical condition that often leads to unnecessary antimicrobial use. The reduction of antibiotic overuse for ABU is consequently an important issue for antimicrobial stewardship to reduce the emergence of multidrug resistant strains. In the clinical setting we have an important issue that requires special attention: the role of ABU in women affected by recurrent urinary tract infections (rUTIs). Read More

cryoEM-Guided Development of Antibiotics for Drug-Resistant Bacteria.

ChemMedChem 2019 Jan 22. Epub 2019 Jan 22.

Infection and Immunity Program, Department of Microbiology, Monash University, Clayton, 3800, Australia.

While the ribosome is a common target for antibiotics, challenges with crystallography can impede the development of new bioactives using structure-based drug design approaches. In this study we exploit common structural features present in linezolid-resistant forms of both methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) to redesign the antibiotic. Enabled by rapid and facile cryoEM structures, this process has identified (S)-2,2-dichloro-N-((3-(3-fluoro-4-morpholinophenyl)-2-oxooxazolidin-5-yl)methyl)acetamide (LZD-5) and (S)-2-chloro-N-((3-(3-fluoro-4-morpholinophenyl)-2-oxooxazolidin-5-yl)methyl) acetamide (LZD-6), which inhibit the ribosomal function and growth of linezolid-resistant MRSA and VRE.

Bloodstream infections with vancomycin-resistant enterococci are associated with a decreased survival in patients with hematological diseases.

Ann Hematol 2019 Mar 21;98(3):763-773. Epub 2019 Jan 21.

Department of Hematology and Oncology, University Hospital Frankfurt, Frankfurt am Main, Germany.

Enterococcus species are commensals of the human gastrointestinal tract with the ability to cause invasive infections. For patients with hematological diseases, enterococcal bloodstream infections (BSI) constitute a serious clinical complication which may even be aggravated if the pathogen is vancomycin-resistant. Therefore, we analyzed the course of BSI due to vancomycin-susceptible enterococci (VSE) in comparison to vancomycin-resistant enterococci (VRE) on patient survival. Read More
