Save my name, email, and website in this browser for the next time I comment. Proteus penneri R Cantón et al. The first ever developed solid differential medium for the growth of bacteria on the globe was MacConkey Agar Medium (MAC medium), was formulated by and is named after a British bacteriologist, Alfred Theodore MacConkey in the 20 th century.. The swarming on agar plates (in broth they grow with a filamentous aspect that is considered to be equivalent to the swarming) is related to the great mobility of cells, and frequently impairs the isolation of colonies and the identification of other bacteria in mixed infections. Proteus mirabilis is most frequently … Required fields are marked *. CLED agar: Blue gray translucent colonies and absence of swarming is due to electrolyte deficient. Sodium azide, barbitone, and sulfonamide also inhibit Proteus swarming (1). My Name Is Kavindu Lakmal , Medical Laboratory Science Student From University Of Peradeniya.
