Dismal prognosis of Pneumocystis jirovecii pneumonia in patients with multiple myeloma.

Patients with multiple myeloma (MM) are at high risk for infections, including opportunistic infections such as Pneumocystis jirovecii pneumonia (PJP). We conducted a retrospective analysis of patients with MM developing PJP over a 6-year period between January 2016 and December 2021 at the University Hospital of Würzburg by screening cases of microbiologically documented PJP. A total of 201 positive results for P.

A streamlined method for the fast and cost-effective detection of bacterial pathogens from positive blood cultures for the BacT/ALERT blood culture system using the Vitek MS mass spectrometer.

Background And Objective: Prompt pathogen identification of blood stream infections is essential to provide appropriate antibiotic treatment. Therefore, the objective of this prospective single centre study was to establish an inexpensive, fast and accurate protocol for bacterial species identification with SDS protein-extraction directly from BacT/Alert® blood culture (BC) bottles by VitekMS®.

Results: Correct species identification was obtained for 198/266 (74.

Epidemiology of Candida blood stream infections in patients with hematological malignancies or solid tumors.

Invasive Candida infections are associated with high morbidity and mortality. Due to an increased incidence in patients with hematological or oncological malignancies, fluconazole prophylaxis became a common practice in many centers in the late 1990s. Until recently, there was insufficient data on the effect of the use of azoles on the incidence of Candida blood stream infections and species distribution.

Evaluation of the VITEK 2 AST-N111 card for detection of extended-spectrum beta-lactamases (ESBLs) in Escherichia coli, Klebsiella pneumoniae, and Klebsiella oxytoca compared to ESBL Etests and combination disk methods.

The VITEK 2 AST-N111 card was evaluated for detection of extended-spectrum beta-lactamases (ESBLs) by testing 51 ESBL positive and 50 ESBL negative isolates of E. coli, K. pneumoniae, and K.

Panton-Valentine leukocidin-positive Staphylococcus aureus infections in returning travelers.

Skin and soft tissue infections caused by Panton-Valentine leukocidin-producing strains of Staphylococcus aureus are emerging among travelers returning from the tropics. Here, we here present data on 15 affected individuals. Intrafamiliar spread was documented in one case, and occupational transmission was assumed in another.
