Describe a key morphological feature that would differentiate each of the following groups of bacteria: Streptococcus, Streptomyces, Spirochaeta.

Solution

Streptococci is a spiral shaped, Gram positive Bacteria. They occur as chains or pairs. These are Facultative anarobes. They lack oxidase and Catalase. Capable to lyse RBC

Streptomyces is the largest genus of Actinobacteria. Gram positive Bacteria and genome possess more GC content. Spore forming bacteria and exit in soil and decay ing matter. They are commercial antibiotics producing organisms. Filamentous bacteria and produce Hyphae. These are infrequent pathogens

Spirochaeta: These are helicle shaped, free living, facultative anarobic bacteria. Exist In fresh and marine water. They also exist in digestive tract of Termites. They are saccharolytic, that means utilise only Carbohydrates. They show symbiotic association with Biggiota
