METHODS OF ISOLATION OF
BACTERIA
10.1 INTRODUCTION
We have learned in earlier chapters that there exist so many bacteria that cause
human disease.so now our task is to isolate these bacteria and identify them. The
identification is required so as to cure the illness or the infection caused due to
these bacteria, using appropriate antibiotics. Identification also holds significance
for epidemiological purposes.
This chapter would focus on various methods used for isolation of bacteria.
While in subsequent chapters we would learn about identification of bacteria and
the ways to contain the infections caused by them.

10.2 ISOLATION OF BACTERIA
Isolation of bacteria forms a very significant step in the diagnosis and
management of the illness. Isolation of bacteria involves various steps –
z Specimen collection
z Preservation and transportation of specimen
