Background: The salivary glands of Lucilia sericata are the first organs to express specific endopeptidase enzymes. These enzymes play a central role in wound healing, and they have potential to be used therapeutically. Methods: Rapid amplification of cDNA ends and rapid amplification of genomic ends wer...
Preliminary bioassays with whole cultures (WC) of 124 Bacillus thuringiensis strains were performed with neonate larvae of Anthonomus grandis, a major cotton pest in Argentina and other regions of the Americas. Three exotic and four native strains were selected for causing more than 50% mortality. All of...
A total of 268 Bacillus thuringiensis strains obtained from different sources of Argentina were analyzed to determine the diversity and distribution of the cryl, cry2, cry8, cry9 and vip3A genes encoding for lepidopteran-specific insecticidal proteins. Twin strains were excluded. Ten different profiles w...

A miíase oral é relativamente comum, principalmente nos países tropicais e subdesenvolvidos e, na maioria das vezes, afeta pacientes acamados, idosos, moradores de rua e pacientes com necessidades especiais, embora possa acometer pacientes saudáveis. Esse tipo de infecção caracteriza-se pela infest...
Abstract Entomopathogenic nematodes (EPN) belonging to the Heterorhabditidae family are lethal parasites of soil-dwelling insects. Two species were reported in Argentina: Heterorhabditis argentinensis and Heterorhabditis bacteriophora characterized mainly by morphometric features. In this work a comparat...
