Abstract:
This study of comparison was conducted to examine the existence of antibiotic resistant
and sensitive bacteria in various environmental samples of Bangladesh with specific
clinical strain obtained from ICDDR,B. From the month April 2014 to September 2014,
these environmental samples were isolated from different locations of Dhaka city to see
the inclination of the environmental isolates to develop antibiotic resistance at different
times of a year. The bacterial isolates were identified on the basis of standard cultural,
morphological and biochemical attributes. Antibiogram was done to determine the
antibiotic susceptibility of the isolates in the way that follows CLSI (Clinical &
Laboratory Standards Institute) guideline. The after effect of this study showed all the
clinical isolates were sensitive to these antibiotics whereas all the environmental isolates
have become resistant to the tested antibiotics, and some of them have emerged to be
multi-resistant to these therapeutic agents. The study serves to anticipate the future
emergence and aide the advancement of strategies and methods to counteract this
resistance. In this way intermittent and far reaching survey of antibiotic resistance in the
natural microbes is needed.
