Beta-Lactamase Production among Uropathogens: An Overview of Consistent Triggers and Current Epidemiological Scenario | Book Publisher International
The natural process of acquiring antibiotic
resistance by micro-organisms is a gradual phenomenon. However, the rampant and
indiscriminative usage of antibiotics have profusely accelerated this process
and laid a profound impact in the world of infectious diseases. Common
infections like urinary tract infections, which were once regarded as harmless
and non-complicated diseases, have now emerged in its most dreadful form due to
increasing evidence of antibiotic resistance among pathogens. This unpleasant
scenario is further alleviated with the help of β-lactam antibiotic hydrolysing
enzymes such as Extended Spectrum β-lactamases (ESBLs) and Metallo β-lactamases
(MBLs). Since β-lactam antibiotics are still widely used, the emergence of
β-lactamase producers has become a matter of serious concern. ESBL enzymes that
were first identified in the 1980s have now spread throughout the world,
especially by nosocomial routes. In most cases, carbapenems are considered as
agents of last resort antibiotics for the treatment of infections due to ESBL
producers. However, with its increased and sometimes unnecessary use, we have
actually triggered the resistant mechanisms against these antibiotics leading
to the emergence of carbapenemase producers. Due to such continuous evolution
of antibiotic resistance, regular monitoring of the same has become extremely
necessary. A study of the general pattern of antibiotic resistance in a
community may improve predictions of their susceptibilities which will be
helpful in implementing treatment measures in emergency situations and during
epidemics.
Considering the problem of evolving antibiotic
resistance, this review article highlights the problems associated with
β-lactamase producers, its molecular complexity and facilitated transferability
that has together led to its enduring success.
