Abstract

Drug resistance is the major cause of increase in morbidity and mortality in neonates. The emergence of antibiotic-resistant bacterial strains requires the exploration of alternative antibacterial therapies and the concern that human kind in re-entering the 'pre-antibiotic era' has become very real and the development of alternative anti-infection modalities has become one of the highest priorities of modern medicine and biotechnology. This has spurred biomedical researchers to expand their efforts to identify new technologies and products that employ novel mechanism of action against the "super-bugs". One of such alternatives stems up from an old idea is the bacteriophage therapy, which led our group to study the ability of bacterial viruses (bacteriophages or phages) to rescue septicemic mice with multidrug resistant (MDR) Klebsiella pneumoniae isolated from neonatal septicemia. The phage strain used in this study had lytic activity against a wide range of clinical isolates of MDR Klebsiella pneumoniae. One of these MDR Klebsiella strain was used to induce septicemia in mice by intraperitoneal (i.p.) injection of 10(9) CFU. The resulting bacteremia was fatal within 48 h. A single i.p. injection of 3x10(8) PFU of the phage str...Continue Reading
