sp. nov. Isolated from Wound Infection After Pacemaker Implantation: Case Report and Literature Review.

is a recognized pathogen in patients with immunodeficiency and a normal immune response, which can cause bacteremia, endocarditis, peritonitis and pulmonary infection. We report a case of wound infection after pacemaker implantation caused by . Matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS) was routinely used to identify the pathogen, and the results showed that the pathogen could not be accurately identified in the MALDI-TOF database at present.

Mutation of TonB-Dependent Receptor Encoding Gene Potentially Associates with Macrolides Resistance in Isolates.

Introduction: , which is an opportunistic pathogen and is one of the three major pathogens of community-acquired pneumonia, causes a variety of infections in clinic. In recent years, the isolation rate of has gradually increased. In China, due to the clinical empirical use of antibiotics, the resistance rate of isolated from children to β-lactam antibiotics has reached 99%.

Insertion Mutation of Play an Important Role in Resistance of to Mycobacteriophage SWU1.

Purpose: Phage is a new choice for the treatment of multi-drug-resistant bacteria, and phage resistance is also an issue of concern. SWU1 is a mycobacteriophage, and the mechanism of its resistance remain poorly understood.

Methods: The mutant strains which were stably resistant to SWU1 were screened by transposon mutation library.
