Book Description
The 1st International Workshop on Acinetobacter was held on 6th September, 1986, in Manchester, England, in association with the 14th International Congress of Microbiology. That occasion was so well attended and productive that there were soon discussions about how, when and where the next meeting should be held. This time, however, there was sufficient confidence to think of a more substantial meeting and to plan for the proceedings to be published. It emerged that there was wide agreement that the time was ripe to take stock of the entire biology of Acinetobacter: its occurrence and taxonomy; its molecular biology, biochemistry and physiology; its clinical importance and its industrial and commercial applications. The 2nd International Workshop on Acinetobacter took place from 6th to 7th September, 1990, at the Institut Pasteur, Paris, and was sponsored by the Federation of European Microbiological Societies. There were about 100 participants from 19 countries. The backbone of the meeting consisted of 23 plenary lectures. There were 28 posters and the meeting closed with a general discussion which went on long after the official finishing time despite all the counter-attractions of a sunny Parisian Friday afternoon. Indeed discussions continued while cruising along the Seine and while dining at the top of the Tour Montparnasse. However, the vitality and usefulness of even the most successful meeting is difficult to transmit by the printed word.

Book Description
The second edition of Microbiology of Waterborne Diseases describes the diseases associated with water, their causative agents and the ways in which they gain access to water systems. The book is divided into sections covering bacteria, protozoa, and viruses. Other sections detail methods for detecting and identifying waterborne microorganisms, and the ways in which they are removed from water, including chlorine, ozone, and ultraviolet disinfection. The second edition of this handbook has been updated with information on biofilms and antimicrobial resistance. The impact of global warming and climate change phenomena on waterborne illnesses are also discussed. This book serves as an indispensable reference for public health microbiologists, water utility scientists, research water pollution microbiologists environmental health officers, consultants in communicable disease control and microbial water pollution students. Focuses on the microorganisms of most significance to public health, including E. coli, cryptosporidium, and enterovirus Highlights the basic microbiology, clinical features, survival in the environment, and gives a risk assessment for each pathogen Contains new material on antimicrobial resistance and biofilms Covers drinking water and both marine and freshwater recreational bathing waters

Book Description
There is currently increasing interest concerning the biology and disease caused by Acinetobacter species. Such interest, however, developed relatively slowly because of the necessity to clarify the confusing taxonomy of these organisms. Much work was needed to identify various species as members of this genus, to recognize their epidemiologic profile, their pathogenic role and their increasing importance as multi-antibiotic resistant organisms. In recent years improvement of genetic approaches, recognition of plasmids, integrons and chromosomal sources of resistance mechanisms aroused interest on the role of Acinetobacters in disease by many microbiologists and clinicians, especially internists and infectious disease specialists. In this regard, physicians are frequently confronted with extremely difficult therapeutic approaches for treatment and prevention of severe nosocomial infections due to multi antibiotic resistant Acinetobacter. Moreover, recent observations of community acquired infections have been reported, especially in patients with various risk factors such as immuno-deficiencies. Also, it is now becoming evident that Acinetobacter infections occur frequently in violent situations such as earthquake or war zones. The mechanisms of Acinetobacter virulence are becoming increasingly clear, providing new insights into their pathogenic role in community acquired infections. It is apparent the time is appropriate for detailed review of the increasing knowledge concerning important new information, both clinical and therapeutic, especially information concerning virulence, resistance mechanisms and typing of Acinetobacter spp. Many new findings are accumulating in almost an exponential manner since publication of previous books on this subject in 1991 and 1996.

Book Description
Lasso peptides form a growing family of fascinating ribosomally-synthesized and post-translationally modified peptides produced by bacteria. They contain 15 to 24 residues and share a unique interlocked topology that involves an N-terminal 7 to 9-residue macrolactam ring where the C-terminal tail is threaded and irreversibly trapped. The ring results from the condensation of the N-terminal amino group with a side-chain carboxylate of a glutamate at position 8 or 9, or an aspartate at position 7, 8 or 9. The trapping of the tail involves bulky amino acids located in the tail below and above the ring and/or disulfide bridges connecting the ring and the tail. Lasso peptides are subdivided into three subtypes depending on the absence (class II) or presence of one (class III) or two (class I) disulfide bridges. The lasso topology results in highly compact structures that give to lasso peptides an extraordinary stability towards both protease degradation and denaturing conditions. Lasso peptides are generally receptor antagonists, enzyme inhibitors and/or antibacterial or antiviral (anti-HIV) agents. The lasso scaffold and the associated biological activities shown by lasso peptides on different key targets make them promising molecules with high therapeutic potential. Their application in drug design has been exemplified by the development of an integrin antagonist based on a lasso peptide scaffold. The biosynthesis machinery of lasso peptides is therefore of high biotechnological interest, especially since such highly compact and stable structures have to date revealed inaccessible by peptide synthesis. Lasso peptides are produced from a linear precursor LasA, which undergoes a maturation process involving several steps, in particular cleavage of the leader peptide and cyclization. The post-translational modifications are ensured by a dedicated enzymatic machinery, which is composed of an ATP-dependent cysteine protease (LasB) and a lactam synthetase (LasC) that form an enzymatic complex called lasso synthetase. Microcin J25, produced by Escherichia coli AY25, is the archetype of lasso peptides and the most extensively studied. To date only around forty lasso peptides have been isolated, but genome mining approaches have revealed that they are widely distributed among Proteobacteria and Actinobacteria, particularly in Streptomyces, making available a rich resource of novel lasso peptides and enzyme machineries towards lasso topologies.

Book Description
Although molecular biology is still limited to a small number of laboratories in developing countries such as Lebanon. In our first line of work, we looked at the problems of Shigella spp. identification in Lebanon by exploiting several phenotypic and molecular approaches on a collection of isolates identified as Shigella spp. The heterogeneous results underline the complexity of differentiating Shigella spp. from Escherichia coli and the need for a well-validated approach in which whole-genome sequencing (WGS) is paramount. Second, we have demonstrated the power of WGS to simultaneously decipher most of the mechanisms behind the multidrug resistance to antibiotics observed in a strain of Campylobacter coli isolated from a newborn with severe diarrhea. Finally, we exploited the role of molecular typing to understand the clonal nature of the Acinetobacter baumannii strains resistant to carbapenems, isolated from the intensive care unit of a tertiary care hospital. Typing has helped us on the one hand to validate the presence of a polyclonal outbreak caused by OXA-23 carbapenemase-producing ST2 strains, and on the other hand to set up timely control measures capable to fully eradicate the outbreak. Thus, we can conclude the need for large-scale implementation of molecular techniques for the identification and decoding the antimicrobial resistance mechanisms in all diagnostic laboratories in Lebanon as well as the ultimate need for reference laboratories doing strain typing and surveillance, thus facilitating the smooth and successful integration of WGS. Henceforth, this latest technology certainly will orchestrate all routine workflows in a clinical microbiology laboratory.
