Objective(s): Phage therapy is a potential alternative treatment for infections caused by Acinetobacter baumannii, a significant nosocomial pathogen, which has evolved resistance to almost all conventional antimicrobial drugs in poor hygiene and conflicts areas such as Iraq. Materials and Methods: Bacteriophages were isolated to highly resistant isolates of A. baumannii to form therapeutic phag...

Background and Objective: Phage therapy could be used as an alternative method to antibiotic treatments. The purpose of this study was to evaluate the antibacterial activities of isolated lytic bacteriophage against ciprofloxacin-resistant strain of Salmonella infanits in vitro conditions. Materials and Methods: The standard strain of Salmonella infantis  and its specific bacteriophage was iso...

Members of the marine dinoflagellate genus Alexandrium are known to exude allelochemicals, unrelated to well-known neurotoxins (PSP-toxins, spirolides), with negative effects on other phytoplankton and marine grazers. Physico/chemical characterization of extracellular lytic compounds of A. tamarense, quantified by Rhodomonas salina bioassay, showed that the lytic activity, and hence presumably ...

Trade-offs between life-history variables can be manifested at either the phenotypic or genetic level, with vastly different evolutionary consequences. Here, we examined whether male decorated crickets (Gryllodes sigillatus) from eight inbred lines and the outbred founder population from which they were derived, trade-off immune effort [lytic activity, phenoloxidase (PO) activity or encapsulati...

Decreased peripheral blood natural killer (NK) cell lytic activity may be associated with tumor presence. We evaluated peripheral blood NK lytic activity in 38 patients with bronchogenic carcinoma and compared this to ten normal volunteers of comparable age. The patients with carcinoma had significantly (P less than 0.001) less NK activity (20 +/- 17 lytic units at 25% specific lysis)/10(6) per...

BACKGROUND Accumulating evidence suggests that dysregulated expression of lytic genes plays an important role in KSHV (Kaposi's sarcoma associated herpesvirus) tumorigenesis. However, the molecular events leading to the dysregulation of KSHV lytic gene expression program are incompletely understood. METHODOLOGY/PRINCIPAL FINDINGS We have studied the effect of KSHV-encoded latent protein vFLIP...

in the present study, we aimed to screen indigenous rhizospheric bacillus strains, capable of producing antiphytopathogenic and plant growth promoting traits. isolate cts-b19 and cts-g24 exhibited quite noticeable antagonistic activity initially against fusarium oxysporum f. sp. ciceri and rhizoctonia bataticola, and, later, against a panel of phytopathogens. partial 16s rrna sequence analysis ...
