Performance standard for antimicrobial disk susceptibility tests.

Author information Article notes Copyright and License information Disclaimer. Both the modified Hodge test and the KPC J100 test performed identically, except for the latter’s advantages of a more rapid turnaround time and less dependence on experience with reading the Hodge tests, which are sometimes difficult to read.

Journal List J Clin Microbiol v. Reevaluation of the cefepime minimal inhibitory concentrations and disk diffusion test zone diameter relationship for a worldwide collection of Enterobacteriaceae enriched for extended-spectrum beta-lactamase-producing organisms. Performance Standards for Antimicrobial Susceptibility Testing: Susceptibilities of Haemophilus influenzaeStreptococcus pneumoniaeincluding serotype 19A, and Moraxella catarrhalis paediatric isolates from to to commonly used antibiotics.

They did not find strains with poor growth when agar was incubated in m00 air. Likewise, the current analysis may not have been adequately powered to assess AST interactions with other genotypes bla TEM or bla SHVand the use of a generic primer may have underestimated the level of association between these genotypes and the error rates.


Effects of new penicillin susceptibility breakpoints for Streptococcus pneumoniae – United States, — Antimicrobial susceptibility of Streptococcus pneumoniae at a university hospital in Taiwan, — We have no conflicts of interest. Neisseria and Moraxella catarrhalisp.

Ceftriaxone non-susceptibility also increased significantly from 2. It has been previously demonstrated that ceftriaxone MICs may exceed those of penicillin for the same strains of S.

Clinically applicable multiplex Cclsi for four middle ear pathogens. Ampicillin-sulbactam, ciprofloxacin, levofloxacin and gentamicin, tobramycin moved to group A. Modification of the error-rate bounded classification scheme for use with two MIC break points. Use of multiplex PCR for simultaneous detection of four bacterial species in middle ear effusions. For Permissions, please e-mail: Performance measures for Vitek 2 determination of cefepime susceptibility compared with those of cefepime agar dilution.

A total of isolates of M. The most frequent etiologic agents of bacterial tonsillitis and tonsillopharyngitis are Streptococcus pyogenes. We evaluated the performance of ertapenem susceptibility screening for KPCs for all mucoid lactose-positive Enterobacteriaceae regardless of susceptibility profile and for clwi broad-spectrum-cephalosporin-resistant Enterobacteriaceae isolated in our laboratory during Published ahead of print 21 April K100 think you have liked this presentation.

Mueller-Hinton agar Remel, Lenexa, KS was prepared according to the manufacturer’s specifications, as previously described In addition, all non-urine source Enterobacteriaceae that underwent susceptibility testing in our laboratory from August to December were included.

Pneumococcal bacteremia with special reference to bacteremic pneumococcal pneumonia. Rhodesa, b Chad L. TABLE 3 Performance measures for Vitek 2 determination of cefepime susceptibility compared with those of cefepime agar dilution. 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 Clinical and Laboratory Standards Institute.

The presence of KPCs was confirmed by both PCR and the modified Hodge test using meropenem as the indicator drug, both performed as previously described 7. A notable feature of the strains that grew well was large zone diameters for strains with low MICs.

The effect of cldi resistance on mortality in adult patients with nonmeningeal systemic pneumococcal infections. Unfortunately, reliable clinical outcome data on clssi antimicrobial agents are scarce and are insufficient to draw conclusions about eradication rates.
