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.
This picture proves antagonistic property of acidophil actinomyces against Escherichia coli. These cultures of actinomyces were isolated from Azerbaijan's soil in 2012 by me. 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
Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More
Serratia marcescens/Escherichia coli mix grown on TSA for 48 hrs. Serratia marcescens grows red due to prodigiosin and Escherichia coli grows opaque white. 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
