1. Biased Evolution : Causes and Consequences
Abstract : In evolution alternative genetic trajectories can potentially lead to similar phenotypic outcomes. However, certain trajectories are preferred over others. These preferences bias the genomes of living organisms and the underlying processes can be observed in ongoing evolution. READ MORE

2. Mechanisms of resistance to ciprofloxacin in Neisseria gonorrhoeae
Abstract : A few years ago, most strains of Neisseria gonorrhoeae were susceptible to ciprofloxacin, but after introduction as a first line therapy, resistant strains emerged. Ciprofloxacin inhibit two enzymes necessary for DNA replication. READ MORE

3. Chromosomal antibiotic resistance mechanisms in Pseudomonas aeruginosa and Neisseria gonorrhoeae
Abstract : The progressive increase in fluoroquinolone resistant N. gonorrhoeae and emergence of multiple antibiotic resistant P. aeruginosa are growing concerns among physicians and health policy makers. In N. READ MORE

4. Studies on the molecular mechanisms of resistance to fluoroquinolones and carbapenems in selected bacterial species
Abstract : The emergence of mutant bacteria with multi-resistant phenotype, no longer responsive to any of the available therapeutic agents is a growing concern. We have investigated the resistance mechanisms to two classes of antibacterials with broad spectrum of activity, carbapenems and fluoroquinolones. READ MORE

5. Constraints on up-regulation of drug efflux in the evolution of ciprofloxacin resistance
Abstract : The crucial role of antibiotics in modern medicine, in curing infections and enabling advanced medical procedures, is being threatened by the increasing frequency of resistant bacteria. Better understanding of the forces selecting resistance mutations could help develop strategies to optimize the use of antibiotics and slow the spread of resistance. READ MORE
