BACKGROUND The objective of the present study was to compare current results of prosthetic valve replacement following acute infective native valve endocarditis (NVE) with that of prosthetic valve endocarditis (PVE). Prosthetic valve replacement is often necessary for acute infective endocarditis. Although valve repair and homografts have been associated(More)
The minimal inhibitory concentrations (MICs) of 5-fluorocytosine (5-FC) and the serotypes were determined for 666 strains of Candida albicans isolated from white patients in Canada. Of these strains, 495 (74.3%) were serotype A and 71 (25.7%) were serotype B. Resistance to 5-FC (MIC, greater than or equal to 25 microgram/ml) was observed in 11.3% of the(More)
BACKGROUND Sternal wound infection remains a significant complication. We reviewed the incidence and the treatment of sternal wound infection after heart transplantation. METHODS Of 226 patients who had a heart transplantation, 20 (8.8%) underwent postoperative wound debridement for superficial or deep sternal wound infection. The incidence and the(More)
Adapting to specific hosts often involves trade-offs that limit performance on other hosts. These constraints may either lead to narrow host ranges (i.e. specialists, able to exploit only one host type) or wide host ranges often leading to lower performance on each host (i.e. generalists). Here, we combined laboratory experiments on field populations with(More)
Infective endocarditis is associated with a high mortality, but previous studies have suggested that the major complications of the condition might be prevented by early surgery. Of 50 patients treated for infective endocarditis at the Montreal Heart Institute from 1977 to 1982, 30 were treated nonsurgically and the remaining 20 underwent early valve(More)
Studies on the prevalence of tinea pedis, a frequently encountered dermatophytic infection, have been conducted mostly in swimmers although people who regularly practise other types of physical activities may also have a high rate of clinical or subclinical infection. This investigation was undertaken to establish the rate of infection in marathon runners,(More)
The fungicidal effect of lysozyme on Candida albicans involves ultrastructural modifications previously described (G. Marquis, S. Montplaisir, S. Garzon, H. Strykowski, and P. Auger, Lab. Invest. 46:627-636, 1982). To further define the action of lysozyme on the yeast cell wall, we used the following: (i) the periodic acid-thiocarbohydrazide-silver(More)
The antifungal activity of hen egg-white lysozyme was investigated in vitro using a hypotonic medium designed to support an anabolic cellular state with minimal growth stimulation. The pathogenic yeast Candida albicans was found to be sensitive to microgram amounts of hen egg-white lysozyme. This susceptibility was evidenced by sluggish growth and a(More)
