Lipid Plate/Tributyrin Agar used to test for an organisms ability to produce the exoenzyme lipase which breaks down the lipids in the agar creating a clear zone around the organism. (A) Serratia marcesens, lipid hydrolysis, indicated by a zone of clearing around the growing colony, as well as th... Read More
Organisms grown in Fluid Thioglycollate Media w/out resazurin dye is a reducing media that uses sodium thioglycollate to chemically combine with dissolved oxygen to deplete the oxygen in the media. All organism except for Neisseria sicca were grown for 48 hours at 37 degrees C. Neisseria sicca i... Read More
Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More
A sample of Proteus mirabilis was inoculated on to a TSA plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a clear halo and finger like projections coming from and around the grow... Read More
This isolate was also Methicillin resistant. It was my first D-test positive S. aureus isolate during my work on Inducible clindamycin resistance among staphylococci at Universal College of Medical Sciences and Teaching Hospital, Bhairahawa, Nepal. Read More
Slime production by Staphylococcus epidermidis on Congo Red agar; demonstrated by black colored colonies. Slime production is one of the most important virulence factors produced by Coagulase negative Staphylococci.
The colonies of slime non-producing strains remain pink to red.
