Spontaneous bacterial peritonitis (SBP) is a recognized cause of morbidity and mortality in cirrhotic patients. Enterobacteriaceae have been isolated from the majority of peritonitis cases and the gram negative aerobe Escherichia coli is the most commonly isolated organism. Anaerobic organisms are rarely isolated because of the high oxygen tension in ascetic fluid. We report a patient with a history of alcoholic cirrhosis who developed SBP and concurrent bacteremia with the anaerobe Clostridium tertium. The patient was successfully treated with intravenous antibiotics and was discharged home on oral ciprofloxacin...

Clostridium difficile (CD) is the most common etiologic agent of antibiotic-associated diarrhea. The number of infections has increased dramatically in the last decade. Although the diseases caused by CD are mostly related to health care and antibiotic therapy, some are community-acquired cases. This article explains the pathogenesis of this microorganism, pointing to depletion of intestinal microflora diversity and the inadequate response of the immune system as an important factor predisposing the development of CD infection...

BACKGROUND: Antibiotic overuse has promoted growing rates of antimicrobial resistance and secondary antibiotic-associated infections such as Clostridium difficile (C. difficile). Antimicrobial stewardship programs (ASPs) are effective in reducing antimicrobial use in the inpatient setting; however, the unique environment of the emergency department (ED) lends itself to challenges for successful implementation. Front-line ownership (FLO) methodology has been shown to be a potentially effective strategy for the implementation of inpatient ASPs through an iterative multi-pronged approach driven by front-line providers...

Necrotizing fasciitis is a potentially fatal soft tissue infection that may affect the upper and lower extremities, scrotum, perineum and abdominal wall. Typically, the infection demonstrates rapid spreading along the fascial planes leading to sepsis with mortality rates of 15-46%. Without adequate treatment, the mortality rate increases to close to 100%. There are four groups of pathogens that can lead to necrotizing fasciitis, namely beta-hemolytic group A streptococci, mixed infections with obligate and facultative anaerobes, clostridium species and fungal infections...
