Changes

Accurate paperwork is essential when culturing in house samples so that changes noted on plates can be recorded over time. Always warm culture plates to room temperature prior to inoculation or cold shock can inhibit a delicate organism from growing on a plate. Different mediums can be a used to select for an organism of interest:

#Blood Agar (BA) is the standard plate used for most samples - in most cases an additional plate is added to give more information about the identity of any organism that successfully grows.

#COBA is selective for Streptococci species, which are ubiquitous in some species and frequently cause opportunistic infections. Tracheal washes, joint samples, and cervical swabs and potential Strep equi cases require this medium in addition to BA.

#CLED with Andrade’s indicator is a useful medium when a swab is likely to grow E coli; the indicator will turn pink and the colonies will have a distinctive look and smell.

#Sabaroud plates are selective for fungi and are useful for skin scrapes where dermatophytes are suspected - for many fungi special incubation requirements (e.g. temperature settings of 30°C for 48 hours) must be met so check the requirement based on the most likely organism to grow.
