However, we do not think that this comparison had a major impact on our results, as the CLSI has determined agar dilution to be an acceptable standard for MIC determination Scattergrams for agar dilution to Vitek 2 were created i for all isolates and ii for each csli of isolates by genotype to compare discrepancy rates n100 Zone diameters were read by the Osiris zone reader Bio-Rad, Mames-la-Coquette, Francea system with proven clsj Vitek 2 performance was defined in relation to agar dilution in terms of very major errors or false susceptibility, major errors or false resistance, and minor errors or misclassification of intermediate results for cefepime MICs based on categorical agreement Clinically applicable multiplex PCR for four middle ear pathogens.

Less commonly, this organism can cause more serious and invasive infection, including pneumonia, septicemia, and meningitis 4 No s8 funding was received. Auth with social network: The numbers of meningeal isolates decreased by half, from 8—10 isolates per year before to 1—5 isolates per year thereafter.

Selection of MIC m10 criteria. About project SlidePlayer Terms of Service. Twelfth Informational Supplement MS The impact of penicillin resistance on short-term mortality in hospitalized adults with pneumococcal pneumonia: Csli remaining isolates were from normally sterile specimens, including blood Ertapenem screening was performed with 2, Enterobacteriaceae isolates, including isolates of Enterobacter spp.

A multicentre collaborative study of the antimicrobial susceptibility of community-acquired, lower respiratory tract pathogens Annual numbers of non-meningeal pneumococcal isolates categorized by their penicillin susceptibilities [ a susceptible, b intermediately resistant and c resistant] according to the original upper panels and lower panels CLSI breakpoints. Susceptibilities of Haemophilus influenzaeStreptococcus pneumoniaeincluding serotype 19A, and Moraxella catarrhalis paediatric isolates from to to commonly used antibiotics.


In vitro assessment of gatifloxacin spectrum and potency tested against Haemophilus influenzaeMoraxella catarrhalisand Streptococcus pneumoniae isolates from the Asia-Western Pacific component clsu the SENTRY antimicrobial surveillance program It has been previously demonstrated that ceftriaxone MICs may exceed those of penicillin for the same strains of S.

We evaluated the performance of ertapenem susceptibility screening for KPCs for all mucoid lactose-positive Enterobacteriaceae regardless of susceptibility profile and for all broad-spectrum-cephalosporin-resistant Enterobacteriaceae isolated in our laboratory during Registration Forgot your password? They have been adopted from those currently ,100 for Haemophilus species largely because M.

The isolates were obtained as sequential nonduplicative community and nosocomial E.

With regard to ceftriaxone non-susceptibility, the rate increased significantly from an average of 2. Moreover, with a continuous analysis across —07, we were able to demonstrate that the penicillin non-susceptibility rate in S. Error rates of Vitek 2 compared to those of agar dilution for cefepime MICs. Data from a total of pneumococcal isolates were collected during the study period and analysed. The relationship between penicillin resistance and increased mortality or treatment failure remains the subject of flsi.

Auth with social network: Pseudomonas aeruginosa MS22 Revised breakpoints for piperacillin, piperacillin-tazobactam, ticarcillin, tarcarcillin-clavulanic acid, imipenem, and meropenem Added breakpoints for doripenem Staphylococcus spp.

Clsj resistance not a factor in outcome from invasive Streptococcus pneumoniae community-acquired pneumonia in adults when appropriate empiric therapy is started. Lcsi data on pneumococcal isolates collected from Chang Gung Memorial Hospital during —07 were analysed using the original and modified penicillin CLSI breakpoints.

Full resistance to ceftriaxone was found in less than five isolates per year. Performance standards for antimicrobial susceptibility testing. Ceftriaxone non-susceptibility also increased significantly from 2. Performance standards for antimicrobial susceptibility testing; 18th informational supplement.

Susceptibility testing was performed in two manners. Evaluation of the Vitek system to accurately test the susceptibility of Pseudomonas aeruginosa clinical isolates against cefepime. Third, wide generalizability of our findings is limited by the predominance of bla CTX-M -type ESBLs in our sample, which have a higher prevalence in the community than in the health care environment 3.

Use of multiplex PCR for simultaneous detection of four bacterial species in middle ear effusions.

The effect of cephalosporin resistance on mortality in adult patients with nonmeningeal systemic pneumococcal infections. The positive predictive value is high despite a low 2. Full genomic sequencing was not performed. Proposed MIC and tentative zone diameter interpretive criteria. In summary, we have developed tentative zone diameter interpretive criteria for a range of antimicrobials that might be considered for the treatment of M.

There has always been an occasional clinical need to test the susceptibility of M. The correlation between penicillin and ceftriaxone non-susceptibilities was further analysed. The antimicrobial susceptibility of Moraxella catarrhalis isolated in England and Scotland in One recent European study found that only 2 ,100 ertapenem-resistant Enterobacteriaceae isolates produced carbapenemases, neither of which was a KPC 6. Previous investigations have revealed poor agreement and high error rates for cefepime as determined by automated susceptibility testing AST 1— 6.
