  2. Antibiotic sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Antibiotic_sensitivity_testing

    In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines.This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant. [1]

  3. Disk diffusion test - Wikipedia

    en.wikipedia.org/wiki/Disk_diffusion_test

    The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the susceptibility ...

  4. McFarland standards - Wikipedia

    en.wikipedia.org/wiki/McFarland_standards

    An example of such testing is antibiotic susceptibility testing by measurement of minimum inhibitory concentration which is routinely used in medical microbiology and research. If a suspension used is too heavy or too dilute, an erroneous result (either falsely resistant or falsely susceptible) for any given antimicrobial agent could occur.

  5. Etest - Wikipedia

    en.wikipedia.org/wiki/Etest

    Etest (previously known as the Epsilometer test) is a way of determining antimicrobial sensitivity by placing a strip impregnated with antimicrobials onto an agar plate. A strain of bacterium or fungus will not grow near a concentration of antibiotic or antifungal if it is sensitive.

  6. Mueller–Hinton agar - Wikipedia

    en.wikipedia.org/wiki/Mueller–Hinton_agar

    Mueller Hinton agar is commonly used in the disk diffusion method, which is a simple and widely used method for testing the susceptibility of bacterial isolates to antibiotics. In this method, small disks impregnated with different antibiotics are placed on the surface of the agar, and the zone of inhibition around each disk is measured to ...

  7. European Committee on Antimicrobial Susceptibility Testing

    en.wikipedia.org/wiki/European_Committee_on...

    European Committee on Antimicrobial Susceptibility Testing (EUCAST) is a scientific committee for defining guidelines to interpret antimicrobial resistance. [1] It was formed in 1997 and is jointly organized by ESCMID , ECDC and other European laboratories.

  8. Group B streptococcal infection - Wikipedia

    en.wikipedia.org/wiki/Group_B_streptococcal...

    GBS-EOD infections presented in infants whose mothers had been screened as GBS culture-negative are particularly worrying, and may be caused by incorrect sample collection, delay in processing the samples, incorrect laboratory techniques, recent antibiotic use, or GBS colonization after the screening was carried out.

  9. Centor criteria - Wikipedia

    en.wikipedia.org/wiki/Centor_criteria

    It was a retrospective study (2008–2010) and looked at 441 children who attended a Belgian hospital emergency department and had a throat swab taken. It concluded that the Centor criteria are ineffective in predicting the presence of Group A beta-haemolytic streptococcus (i.e. antibiotic treatment-worthy) on throat swab cultures in children. [4]
