OBJECTIVE To describe antimicrobial susceptibility testing practices of veterinary diagnostic laboratories in the United States and evaluate the feasibility of collating this information for the purpose of monitoring antimicrobial resistance in bacterial isolates from animals. DESIGN Cross-sectional study. PROCEDURES A questionnaire was mailed to veterinary diagnostic laboratories throughou...

SETTING Initial isolates should be tested for drug susceptibility to confirm the anticipated effectiveness of chemotherapy. OBJECTIVE To evaluate E-test strips for susceptibility testing of Mycobacterium tuberculosis. DESIGN A proportion method using Lowenstein-Jensen medium and the Bactec radiometric system were compared with the E-test (isoniazid [INH], rifampicin [RMP], ethambutol [EMB] ...

background nosocomial infections are generally occurring 72 hours after admittance and are not present or incubating prior to admittance. the most common nosocomial infection is urinary tract infection (uti). scanty data are available regarding the nosocomial infections in iranian teaching hospitals. the aim of the present study was to determine the frequency of symptomatic nosocomial uti, iden...

plants are potent biochemists; biologically active compounds present in the medicinal plants have always been ofgreat interest to scientists working in this field. thus, the aim of the current study was to screen the antimicrobial activity of acacia nilotica, ziziphus mauritiana, bauhinia variegate and lantana camara against some selected clinical isolated strains. although previous studies hav...

The resistance of Helicobacter pylori to antibiotics leaves great influence on treatment outcome. Routine antimicrobial susceptibility testing of H. pylori should be a simple, inexpensive and standardized method to be adopted. Agar and broth dilution techniques are difficult to perform and not practical. E-test and disk diffusion methods have the advantage of allowing the visualization of resis...

Antimicrobial susceptibility testing for Helicobacter pylori is increasingly important due to resistance to the most used antimicrobials agents. Only agar dilution method is approved by CLSI, but it is difficult to perform routinely. We evaluated the reliability of E-test and disk diffusion comparing to agar dilution method on Helicobacter pylori antimicrobial susceptibility testing. Susceptibi...

The primary aim of this study was to evaluate the level of agreement of the E-test for in vitro antimicrobial susceptibility testing of Campylobacter coli using the agar dilution technique, which is the approved method. A convenience sample of 80 Ontario swine farms was chosen for this study; each farm was visited from January to June 2004. A total of 233 isolates of C. coli were tested for sus...

BACKGROUND & OBJECTIVES Urinary tract infection (UTI) remain the common infections diagnosed in outpatients as well as in hospitalized patients. Current knowledge on antimicrobial susceptibility pattern of uropathogens is mandatory for appropriate therapy. Extended spectrum beta lactamases (ESBL) hydrolyse expanded spectrum cephalosporins like ceftazidime, cephotaxime which are used in the trea...

background extended-spectrum β-lactamase (esbl)-producing klebsiella pneumonia has become widespread in hospitals and is increasing in community settings. most of k. pneumonia that harbor these enzymes, display resistance to other unrelated antimicrobial agents and thus, often pose a therapeutic dilemma. objectives this study was conducted to determine the prevalence of esbl-producing k. pneumo...
