The PvD1 defensin was purified from Phaseolus vulgaris (cv. Pérola) seeds, basically as described by Terras et al. [Terras FRG, Schoofs HME, De Bolle MFC, Van Leuven F, Ress SB, Vanderleyden J, Cammue BPA, Broekaer TWF. Analysis of two novel classes of plant antifungal proteins from radish (Raphanus sativus L.) seeds. J Biol Chem 1992;267(22):15301-9], with(More)
In recent years, studies have demonstrated the function of many antimicrobial peptides against an extensive number of microorganisms that have been isolated from different plant species and that have been used as models for the study of various cellular processes linked to these peptides’ activities. Recently, a new defensin from Phaseolus vulgaris (L.)(More)
A 6,000 Da peptide, named CaTI, was isolated from Capsicum annuum L. seeds and showed potent inhibitory activity against trypsin and chymotrypsin. The aim of this study was to determine the effect of CaTI on Saccharomyces cerevisiae, Candida albicans, Candida tropicalis and Kluyveromyces marxiannus cells. We observed that CaTI inhibited the growth of S.(More)
Forty children with a diagnosis of Visceral Toxocariasis were evaluated prospectively from February 1982 to June 1989. Diagnosis was established by clinical, laboratory and serological (ELISA - ES Toxocara canis antigen) evaluations. A great clinical polymorphism was found in our patients, ranging from unspecific or absent manifestations to an exuberant(More)
Many Fusarium species are able to cause severe infections in plants as well as in animals and humans. Therefore, the discovery of new antifungal agents is of paramount importance. CaThi belongs to the thionins, which are cationic peptides with low molecular weights (∼5 kDa) that have toxic effects against various microorganisms. Herein, we study the(More)
BACKGROUND During the last few years, a growing number of antimicrobial peptides have been isolated from plants and particularly from seeds. Recent results from our laboratory have shown the purification of a new trypsin inhibitor, named CaTI, from chilli pepper (Capsicum annuum L.) seeds. This study aims to evaluate the antifungal activity and mechanism of(More)
