This study provides a contemporary epidemiology of aspirates taken during surgery from the abdominal cavity among patients with bacterial peritonitis to identify the isolates and study their sensitivity to antibiotics. Our bacteriology investigations included isolation of poor cultures, and detection of microbes was conducted using a rapid identification system (API20E, API Staph, API Strep, API Ana, BioMerieux). Rapid tests for detection of oxidase and catalase activity were also used. Susceptibility of microorganisms to antibiotics was defined by the disc-diffusion method using standard discs (EUCAST guidelines 2015) according to Clinical Laboratory Standard Institute (CLSI) protocols (ATB strips: ATB G, ATB Staph, ATBANA, ATBPse, ATBStrep...

OBJECTIVES: Reduced susceptibility to penicillin G in Neisseria meningitidis is mainly due to alterations in PBP2 encoded by the penA gene. However, this phenotype was not associated with reduced susceptibility to third-generation cephalosporins (C3Gs). We aimed to study the emergence of meningococci with reduced susceptibility to C3Gs (MIC >0.06 mg/L) in France since 2012. METHODS: Invasive meningococcal isolates were typed by MLST and penA sequencing and their antibiotic susceptibility was tested...

BACKGROUND: Gram-negative microorganisms are uncommon pathogens responsible for infective endocarditis. Pseudomonas mendocina, a Gram-negative water-borne and soil-borne bacterium, was first reported to cause human infection in 1992. Since then, it has rarely been reported as a human pathogen in the literature. We describe the first case of native valve infective endocarditis due to P. mendocina in the USA. CASE PRESENTATION: A 57-year-old white man presented with bilateral large leg ulcers, fever, and marked leukocytosis...

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a common infection in cirrhosis associated with high mortality. More than 20% of patients with SBP do not respond to initial antibiotics. Guidelines differ in recommendations to repeat paracentesis (retap) to confirm antibiotic efficacy. We aim to evaluate the effect of retap-guided management of SBP on antibiotic escalation and 30-day transplant-free survival. MATERIALS AND METHODS: Retrospective cohort study of cirrhotic patients with SBP admitted to a single transplant center from 2010 to 2014...

: Klebsiella pneumoniae, one of the most important nosocomial pathogens, is becoming a major problem in health care because of its resistance to multiple antibiotics including cephalosporins of the latest generation and more recently even carbapenems. This is largely due to the spread of plasmid-coded extended spectrum β-lactamases. However, antimicrobial agents must first penetrate through the outer membrane barrier in order to reach their targets, and hydrophilic and charged β-lactams presumably diffuse through the porin channels...

Ceftiofur is a broad-spectrum third generation cephalosporin, which acts by inhibiting bacterial cell wall synthesis. It is active against Gram-positive and Gram-negative bacteria such as Aeromonas hydrophila and β-lactamase-producing strains, which are common pathogens in freshwater fish. Ceftiofur pharmacokinetics in Nile tilapia Oreochromis niloticus were studied following single intracardiac (i.c.) or intramuscular (i.m.) administration of ceftiofur sodium (NAXCEL®) in a dose of 5 mg ceftiofur kg-1 body weight...
