1. Isolation And Identification Of Bacterial Pathogens

Front 1

Microbiologists must identify and isolate the causative agent of an infectious disease within 48 hours of recieving a specimen. This early identification is important why?

Back 1

1) Minimize severity and duration of a disease if proper treatment can be initiated immediately
2) Identify the most suitable antibiotic for treatment of the infection
3) Identify the causative agent of a disease outbreak in a hospital setting (contaimined supplies, poor aspeptic technique used by hospital staff)

Front 2

After examination of a patient, what happens?

Back 2

Physician collections samples from infection site (blood urine, cerebrospinal fluid, pus) and it must be collected to ensure its from the infection site and the metabolitic requirements of pathogen must be provided (anoix conditions) to ensure that bacteria survive during transport to lab

Front 3

What is an example of a general purpose media?

Back 3

Blood agar
-Blood agar supports growth of most aerobic and faculative anaerobic bacteria
-Enriched media may be required for the culture of metabolically fastidious bacteria
-Also contains growth factors

Front 4

What's selective media?

Back 4

Is one in which compounds are used to inhibit the growth of certain bacteria but not other types of bacteria

Front 5

Whats differential media

Back 5

Is one in which an indicator dye allows identification of bacteria by their appearance on the growth media
