BACTERIAL IDENTIFICATION TESTS 11.1 INTRODUCTION In the previous chapter we have discussed various methods of isolation of bacteria. The bacteria thus isolated needs to be further identified to genus and species level. The identification is required so as to cure the illness or the infection caused due to the bacteria by using appropriate antibiotics. Identification also holds significance for epidemiological purposes. OBJECTIVES After reading this chapter, you will be able to ...
