Antibiotics resistance mechanism

Image
  Bacteria develop ability to hydrolyze these drugs using   β lactamase confers resistance to penicillin e.g. E. coli, Staph epidermidis, Pseudomonas aeruginosa, Klebsiella pneumoniae add  β lactamase inhibitor  e.g. clavulanic acid in amoxicillin-clavulanate (Augmentin) Genetic mutation of  mecA carried by Staphylococcal cassette chromosome (SCCmec) mobile genetic unit a bacterial gene encoding a penicillin-binding protein (PBP2a).  PBP2a has reduced affinity for antibiotics confers resistance to methicillin, oxacillin, nafcillin e.g. MRSA SCCmec type IV has less genetic elements and is specific to CA-MRSA, making CA-MRSA less multi-drug resistant Altered cell wall permeability confers resistance to tetracyclines, quinolones, trimethoprim and  β lactam antibiotics Creation of biofilm barrier  provides an environment where offending bacteria can multiply safe from the hoste immune system Salmonella Staph epidermidis Active efflux pumps confers res...

Microbial Diversity

Image
  Microbial diversity  can be defined as the range of different kinds of unicellular organisms, bacteria, archaea, protists, and fungi.  Our new understanding of  microbial diversity  will allow us to cure disease, engineer and conserve our environment, manufacture better products, grow more food, colonize other worlds, and so much more.
