From 1997 to 1999, 94 study centers in 15 European, 3 North American, and 2 South American countries contributed 2,632 isolates of Streptococcus pneumoniae to an international antimicrobial susceptibility testing study. Only 62.0% of isolates were su

Ampicillin, trimethoprim-sulfamethoxazole, mecillinam, nitrofurantoin, and ciprofloxacin mean resistance rates for 2,000 urinary tract isolates collected from outpatients across Canada in 1998 were 41.1, 19.2, 14.7, 5.0, and 1.8%, respectively. For E

Vancomycin-resistant enterococci (VRE) colonization of high-risk patients in tertiary care Canadian hospitals. Canadian VRE Surveillance Group

Autor: J A, Karlowsky, G G, Zhanel, D J, Hoban

Publikováno v: Diagnostic microbiology and infectious disease. 35(1)

We isolated 1487 Enterococcus species from 1200 stool specimens collected from high-risk patients in 12 Canadian tertiary care hospitals between October 1995 and November 1996. The composition of the 1487 isolates was 601 vancomycin-sensitive Enteroc

Prevalence of antimicrobial resistance in respiratory tract isolates of Streptococcus pneumoniae: results of a Canadian national surveillance study. The Canadian Respiratory Infection Study Group

Autor: G G, Zhanel, J A, Karlowsky, L, Palatnick, L, Vercaigne, D E, Low, D J, Hoban

Publikováno v: Antimicrobial agents and chemotherapy. 43(10)

From October 1997 to November 1998, 1,180 respiratory tract isolates of Streptococcus pneumoniae were collected from 18 medical centers in 9 of the 10 Canadian provinces. Penicillin-intermediate and -resistant isolates occurred at rates of 14.8 and 6

Evolving patterns of resistance to respiratory pathogens in Canada

Autor: D J, Hoban, J A, Karlowsky, G G, Zhanel

Publikováno v: Canadian respiratory journal. 6

Active surveillance of changing resistance patterns is difficult but important for rational therapeutic choices. In Canada, penicillin resistance in Streptococcus pneumoniae has evolved more slowly than in other countries (in Europe and Israel rates

Screening of stool samples for identification of vancomycin-resistant Enterococcus isolates should include the methyl-alpha-D-glucopyranoside test to differentiate nonmotile Enterococcus gallinarum from E. faecium

Autor: C Y, Turenne, D J, Hoban, J A, Karlowsky, G G, Zhanel, A M, Kabani

Publikováno v: Journal of clinical microbiology. 36(8)

The methyl-alpha-D-glucopyranoside (MDG) test has been shown to be superior to motility testing in differentiating Enterococcus faecium from E. gallinarum. In the present study, 33 vancomycin-resistant enterococcus (VRE) isolates collected as part of

Aminoglycoside adaptive resistance

Autor: J A, Karlowsky, S A, Zelenitsky, G G, Zhanel

Publikováno v: Pharmacotherapy. 17(3)

Aminoglycoside adaptive resistance is defined as reduced antimicrobial killing in originally susceptible bacterial populations after initial incubation with aminoglycoside. It is observed in vitro and in vivo, most commonly with Pseudomonas aeruginos

Influence of human urine on the in vitro activity and postantibiotic effect of ciprofloxacin against Escherichia coli

Autor: G G, Zhanel, J A, Karlowsky, R J, Davidson, D J, Hoban

Publikováno v: Chemotherapy. 37(3)

The purpose of this investigation was to study the effects of human urine on the minimum inhibitory concentration (MIC) and the postantibiotic effect (PAE) of ciprofloxacin against Escherichia coli. MICs and the PAE were performed in Mueller-Hinton b
