Human infection by the vector-borne protozoan Leishmania is responsible for substantial worldwide morbidity and mortality. The surface-metalloprotease (leishmanolysin) of Leishmania is a virulence factor which contributes to a variety of functions including evasion of complement-mediated parasite-killing and host intramacrophage survival. We tested the(More)
We investigated the effect of topical temporin A in the management of methicillin-resistant strain of Staphylococcus aureus (MRSA)-infected experimental surgical wounds in mice. The wound, cut through the panniculus carnosus of BALB/c mice, was inoculated with 5x10(7) colony-forming units of MRSA. Mice were treated with Allevyn, temporin A-soaked Allevyn,(More)
We investigated cytotoxic activity of antimicrobial peptides of different origin (both naturally occurring and synthetic), structure and known mechanisms of action against human histiocytic lymphoma cell line U937. The strongest cytotoxic activity against U937 cell line was shown by Pexiganan MSI-78, followed by Citropin 1.1, Protegrin 1 and a synthetic(More)
Aim of our study was to investigate the in vitro effects of Tachyplesin III (TP), a potent disulfide-linked peptide, in dermatophytes infections, with respect to or in combination with terbinafine (TERB), against 20 clinical isolates of dermatophytes belonging to four species. A broth microdilution method following the CLSI recommendations (M38-A) was used(More)
We investigated the efficacy of Tachyplesin III alone or combined with piperacillin-tazobactam (TZP) to prevent biofilm formation in vitro and in a rat model of Pseudomonas aeruginosa ureteral stent infection. We have observed that in vitro TZP, in presence of Tachyplesin III, showed minimal inhibitory concentrations (MIC)s twofold and minimal bactericidal(More)
Staphylococcal infections are often associated with the use of implantable medical devices. Such infections are difficult to treat because of biofilm resistance to antibiotics and are common causes of morbidity and mortality. Graft infections were established in the back subcutaneous tissue of adult male Wistar rats by implantation of Dacron prostheses(More)
Like other endogenous enkephalinase inhibitors, human opiorphin peptide (QRFSR) attenuates catabolism of enkephalins and appears to be a promising therapeutic, displaying antinociceptive action in several pain models. However, its opioid-like side-effect profile is insufficiently characterized. In the present set of experiments, acute intraperitoneal(More)
The aim of our study was to evaluate the in vitro activity of IB-367 and its bactericidal effect for Pseudomonas aeruginosa and Escherichia coli, associated to a synergic study to test the antibiotic combinations between the peptide and colistin or imipenem. Minimum inhibitory concentrations (MICs), the minimum bactericidal concentrations (MBCs), the(More)
The in vitro activity of the lipopeptide PAL-Lys-Lys-NH(2) (PAL), alone or combined with either fluconazole (FLU) or amphotericin B (AMB), was investigated against 14 Cryptococcus neoformans isolates. PAL MICs ranged from 1.0 to 4.0 microg/ml. Fungicidal activity was observed. Synergy, defined as a fractional inhibitory concentration (FIC) index of < or(More)
OBJECTIVES An experimental study was performed to evaluate both in vitro and in vivo the kind of interaction between the Laur-CKK-NH2 dimer and daptomycin using two Enterococcus faecalis strains with different patterns of susceptibilities. METHODS We evaluated whether selection for daptomycin-resistant E. faecalis could be prevented in vitro by combining(More)
