Use of specific agar plates for early detection of anaerobic bacteria in surgical site infections after spinal surgery: a prospective single centre study.

To determine if additional agar plates could allow earlier detection of anaerobes in spinal surgical site infections (SSIs), we performed a prospective study (November 2017-January 2019) of patients with early spinal SSIs. In addition to routine 14-day cultures, surgical samples were inoculated onto three additional plates (CDC anaerobe agar with 5% sheep blood [CDC], CDC anaerobe laked sheep blood agar with kanamycin/vancomycin [BBL], and Bacteroides bile esculin [BBE] agar with amikacin (BD, USA)) incubated under anaerobic conditions (72 h, 37°C). The primary endpoint was detection of anaerobes by these methods, as compared to routine culture.

Mycobacterium bovis infection of an aortobifemoral bypass graft with Streptococcus intermedius superinfection after intravesical bacillus Calmette-Guérin immunotherapy for bladder cancer.

Background: The Bacillus Calmette-Guerin (BCG) is a life-attenuated form of Mycobacterium bovis widely used as immunotherapy for localized bladder cancer. Adverse reactions to intravesical BCG instillations are rare.

Case: We describe a 70-year-old man with a history of an aortobifemoral bypass graft, placement of a synthetic mesh for treatment of a ventral hernia and, most recently, superficial bladder cancer treated with BCG therapy.

Comparative evaluation of the QMAC-dRAST V2.0 system for rapid antibiotic susceptibility testing of Gram-negative blood culture isolates.

To comparatively evaluate the performance of the rapid antimicrobial susceptibility testing (AST) system QMAC-dRAST V2.0 and of standard disk diffusion in agar, AST was performed directly from 100 positive blood culture bottles with Gram-negative bacilli. AST results provided by QMAC-dRAST showed 92.

Successful 6-Week Antibiotic Treatment for Early Surgical-site Infections in Spinal Surgery.

Background: The incidence of spinal surgical site infections (SSIs) remains stable at less than 10%. Surgical reinterventions may be hampered by decubitus, treatment-related adverse events, and cost. In the context of emergence of bacterial resistance, a short duration of antimicrobial treatment is of critical importance.
