Book Description
Acinetobacter baumannii is a formidable global pathogen notorious for its widespread drug-resistant nature. It is a major culprit in various infections, particularly targeting immunocompromised individuals in intensive care units (ICUs). A paramount concern associated with this pathogen lies in its remarkable ability to develop resistance to nearly all clinically utilized antibiotics. Furthermore, it exhibits a concerning propensity to disseminate this resistance rapidly, transcending borders and impacting healthcare facilities across diverse economic strata. Of particular focus is the carbapenem-resistant strain of A. baumannii (CRAb). This strain has garnered the top spot on the World Health Organization's (WHO) list of pathogens, necessitating urgent attention for new treatment development. This book delves into numerous studies underscoring the pivotal role of A. baumannii as one of the most impactful bacteria contributing to Healthcare-Associated Infections (HAIs) within the contemporary healthcare landscape.

Book Description
Pseudomonas aeruginosa and Acinetobacter baumannii are among the most common non-lactose-fermenting Gram-negative pathogens responsible for hospital-acquired infections, especially in intensive care units (ICUs). The treatment of infections caused by these bacteria is complicated due to the emergence of multi-drug resistance as the two species are noted for their intrinsic resistance to antimicrobial agents and their ability to acquire genetic elements that encode for resistance determinants. In both species, resistance to multiple classes of antimicrobial agents can seriously compromise the ability to treat infected patients, especially the immunocompromised. Consequently, very few antimicrobials remain as treatment options. Mechanisms of resistance in both of these pathogens include the production of β-lactamases and aminoglycoside-modifying enzymes as well as reduced or lack of expression of outer membrane proteins, mutations in topoisomerases, and up-regulation of efflux pumps. To that purpose, the findings of the studies included in this book deal with the prevalence of resistant isolates to various antimicrobial agents in both P. aeruginosa and A. baumannii, their underlying mechanisms of resistance, their virulence factors, their pathogenesis, and prospective treatment options. Special thanks are due to Mr. Bassam El-Hafi for facilitating procedures involved in this publication.

Book Description
Multiple drug resistance among bacteria has become a global issue with a considerable impact on the mortality associated with infectious diseases. This book is a detailed compilation of available knowledge on the surveillance and mechanisms of antibiotic resistance in various countries throughout the world. Readers will be updated on current information on the understanding of mechanisms involved in drug resistance and the geographical distribution of resistance determinant markers. This volume should be a useful guide for microbiologists and clinicians interested in designing antimicrobial therapies tailored for patients in specific geographical regions.

Abstract: Acinetobacter baumannii is an important nosocomial pathogen worldwide because of its remarkable ability to acquire antibiotic resistance. The global emergences of multidrug-resistant A. baumannii (MDR-AB) clones are predominated by a number of widely disseminated clones, namely clonal complex (CC) 1, CC2, and CC3. In early 2010, we reported two major clones of MDR-AB, designated HKU1 and HKU2 belong to sequence types (ST) 96 and ST92, widely disseminating in our hospitals. ST92 is a predominant clone that is prevalent in more than 30 countries, whereas ST96 has been identified recently and is geographically confined to certain parts of China. Our previous study only investigated the isolates collected in the year 2005-2006. We therefore extended our investigation over a six-year period (2005-2010) to generate a more complete picture of the molecular epidemiology and resistance mechanisms in A. baumannii. Firstly, we performed the susceptibility test on various antimicrobial agents and employed molecular methods to characterize the epidemiology of the target A. baumannii isolates. For the entire study period, increased resistance rates were noted for the seven antimicrobial agents, namely imipenem, piperacillin-tazobactam, cefoperazone, ticarcillin-clavulanate, ciprofloxacin, gentamicin and amikacin (P Secondly, we compared the biological fitness of the circulating clones by performing the doubling time and adhesion experiment. The results demonstrated that HKU3/ST254 has a higher capability for replication and adherence to human bronchial epithelial cells. Together with the higher antibiotic resistance rate, the selective advantages in terms of biological fitness may facilitate the clonal expansion and wide dissemination of this lineage. Finally, whole genome sequence data showed a high amount of resistance genes intermixed with various insertion sequence (IS) elements, integrons and transponsons clustering inside the resistance islands. The presence of a second genomic resistance island conferring aminoglycoside and sulphonamide resistance, additional loci outside the resistance islands harbouring resistance genes and the high amount of antibiotic efflux pumps in various A. baumannii genomes demonstrated that resistance islands contribute a significant part to the multidrug-resistant phenotype in A. baumannii but are not the only factor. The correlation analysis further demonstrated the significance of IS elements in the dissemination of antibiotic resistance genes in the A. baumannii genomes. As a whole, whole genome sequence data may provide an informative and efficient approach to gen
