Introduction of Tinsdale Agar Tinsdale Agar is used for selective isolation and differentiation of Corynebacterium diphtheriae and it is Gram-positive, facultatively anaerobic, non-motile bacteria that exhibit a fermentative metabolism (carbohydrates to lactic acid) under certain conditions. Most species of genus Corynebacterium are normal flora of humans present virtually at all anatomic sites. Corynebacterium diptheriae is the causative agent of Diphtheria. Tinsdale Agar was developed by Tinsdale for the selective isolation and differentiation of Corynebacterium diphtheriae from diphtheroids and...

Introduction of Tellurite Blood Agar Tellurite Blood Agar is applied for the selective isolation and cultivation of Corynebacterium species and they are Gram-positive, facultatively anaerobic, non-motile bacteria that exhibit a fermentative metabolism (carbohydrates to lactic acid) under certain conditions. Most species are normal flora of humans present virtually at all anatomic sites. Tellurite Blood Agar is a selective medium used for the isolation and cultivation of Corynebacterium species. It is selective due to the presence of...

Introduction of Loeffler Serum Slope Loeffler Serum slope is used for the cultivation of Corynebacterium diphtheriae. It was originally devised by Loeffler and further modified by Perry and Petran and Buck. Loeffler serum slope enhances primary and secondary isolation and cultivation of fastidious pathogenic microorganisms especially from the nose and throat which also restores virulence and other identifying properties after they have been lost due to prolonged incubation or repeated subculturing. This Loeffler medium is also...
