variations in the expressed antimicrobial peptide repertoire of northern leopard frog (rana pipiens) populations suggest intraspecies differences in resistance to pathogens.the northern leopard frog (rana pipiens or lithobates pipiens) is historically found in most of the provinces of canada and the northern and southwest states of the united states. in the last 50 years, populations have suffered significant losses, especially in the western regions of the species range. using a peptidomics approach, we show that the pattern of expressed antimicrobial skin peptides of frogs from three geographically separated populations are distinct, and we report the presence of ...200919622371
colonization of hospitalized patients by staphylococcus aureus, staphylococcus epidermidis and enterococci.patients admitted to a medical intensive care unit (29), a surgical intensive care unit (29) and a general medical ward (34) were studied to determine the frequency of colonization by staphylococcus aureus, staph. epidermidis and enterococci. cultures of anterior nares, pharynx, axilla, periurethral tissues, and rectum were done within 24 h of admission and every 48-72 h thereafter for the duration of hospitalization. we found staph. aureus colonization of pharynx, axilla, periurethral tissues a ...19852862193
dynamics of coagulase-negative staphylococcal colonization in patients and employees in a surgical intensive care unit.because there is little information about the frequency of carriage of various species of coagulase-negative staphylococci (cns) in hospital staff, we prospectively investigated nasal cns in patients and personnel in a surgical intensive care unit (sicu). the majority of cns from personnel were staphylococcus epidermiditis. the cns species from patients on admission were more diverse and included multiply antibiotic-resistant s. haemolyticus. patients' cns became more like cns colonizing personn ...19921350601
can this prosthesis be saved?: implant salvage attempts in infected primary débridement with polyethylene liner exchange (odpe) remains a relatively low morbidity option in acute infection of total knee arthroplasty (tka), but concerns regarding control of infection exist. we sought to identify factors that would predict control of infection after odpe.201120544317

matrix-assisted laser desorption ionization time of flight mass spectrometry and diagnostic testing for prosthetic joint infection in the clinical microbiology laboratory.identification of pathogen(s) associated with prosthetic joint infection (pji) is critical for patient management. historically, many laboratories have not routinely identified organisms such as coagulase-negative staphylococci to the species level. the advent of matrix-assisted laser desorption ionization time of flight mass spectrometry (maldi-tof ms) has enhanced clinical laboratory capacity for accurate species-level identification. the aim of this study was to describe the species-level ide ...201525533615
