Abstract: A method of rapidly evaluating the susceptibility of a strain of bacteria to a cell wall synthesis inhibiting antibiotic based on an assessment of cell enlargement in response to doses of the cell wall synthesis inhibiting antibiotic which are correlated to breakpoints of bacterial susceptibility.

Abstract: The present invention refers to a method for the production of live attenuated bacterial strains, suitable as vaccine candidates, comprising the steps of: A. providing a bacterial strain capable of expressing glutamate racemase and possibly D-amino acid transaminase and comprising a peptidoglycan cell wall, and B. inactivating the gene or genes encoding for the glutamate racemase enzyme and, if needed, the gene or genes encoding for the enzyme D-amino acid transaminase in such way that the bacterial strain is no longer capable of expressing a functional glutamate racemase and/or a functional D-amino acid transaminase; wherein the inactivation of said genes causes said bacterial strain to be auxotrophic for D-glutamate.

Abstract: The present invention relates to a method for the rapid evaluation of bacterial susceptibility or non-susceptibility of bacteria to antibiotics that inhibit protein synthesis. The rationale is to identify bacterial responses that depend or are influenced by protein synthesis. If this response is prevented or reduced by the antibiotic that inhibits the protein synthesis, the bacteria are susceptible to this antibiotic. Otherwise, if the response keeps similar despite the incubation with the antibiotic, the bacteria are not susceptible or resistant to this antibiotic. These responses could be determined at the DNA lev-el, cell wall level, morphological level or any other experimental approach, including metabolic, bio-chemical, physiological or genetic processes.

Abstract: The present invention relates to a method for evaluating the integrity of the cell wall of the bacteria present in a culture in the presence of an antibiotic acting on the bacterial cell wall which, from a practical point of view, allows quickly determining if a bacterium is sensitive or resistant to an antibiotic acting on the bacterial cell wall. Likewise, the present invention also relates to a lysis solution applicable in the preceding method, specifically affecting bacteria having the cell wall damaged by the action of an antibiotic acting on the bacterial cell wall, which allows distinguishing bacteria sensitive to said antibiotic from those resistant to said antibiotic.
