We studied infestation rates and parasite-host associations between streblid flies and phyllostomid bats in an Atlantic Forest area of Rio de Janeiro state, southeastern Brazil. We captured 301 individuals from seven Phyllostomidae bat species. Out of that total, 69 bats had been parasitised by nine Streblidae species; the most frequent species were(More)
We examined Brazilian species of the nectar-feeding bats genus Lonchophylla (Phyllostomidae, Lonchophyllinae) to clarify the identity of Lonchophylla bokermanni and to determine the distribution of this and other species of Lonchophylla in eastern Brazil. As a result, we have found sufficient differences between Cerrado populations (including the type(More)
Acyl sugars are allelochemicals present at high concentrations in leaves of accessions of the wild tomato Solanum pennellii; they confer resistance to a large number of arthropod pests, including the tomato pinworm, Tuta absoluta (Lepidoptera, Gelechiidae). Accession 'LA716', with high contents of acyl sugars in the leaves, was used as a source of(More)
We aimed to determine the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in fecal samples of healthy pigs, and to evaluate their clonality and associated resistance. Forty-nine percent of pigs sampled (n=35/71) in a slaughterhouse in Portugal revealed ESBL-producing E. coli isolates. Most isolates produced CTX-M-1 enzyme(More)
beta-Ionone (BIO) is a degraded (C(13)) sesquiterpenoid compound found in a variety of edible and aromatic plants. BIO and other ionone derivatives have been used in fragrance products and as flavoring food additives. In this study we investigated the mutagenic and antimutagenic activities of BIO using the Salmonella/microsome assay. Mutagenicity was(More)
alpha-Bisabolol (BISA) is a sesquiterpene alcohol found in the oils of chamomile (Matricaria chamomilla) and other plants. BISA has been widely used in dermatological and cosmetic formulations. This study was undertaken to investigate the mutagenicity and antimutagenicity of BISA in the Salmonella/microsome assay. Mutagenicity of BISA was evaluated with(More)
We describe Lonchophyllainexpectata sp. n. from the Caatinga of Brazil. This new species can be distinguished from all known species of Lonchophylla that occur in Brazil by dental traits, cranial size, and fur colour. Specimens of Lonchophyllainexpectata have been misidentified as Lonchophyllamordax; but Lonchophyllainexpectata is a pale-venter species,(More)
INTRODUCTION The purposes of this study were to evaluate and compare the immediate effects of rapid maxillary expansion (RME) in the transverse plane with Haas-type and hyrax-type expanders by using cone-beam computed tomography. METHODS A sample of 33 subjects (mean age, 10.7 years; range, 7.2-14.5 years) with transverse maxillary deficiency were(More)
The wild tomato, Solanum pennellii, is an important source of resistance genes against tomato pests. This resistance is due to the presence of acyl sugars (AS), which are allelochemicals that have negative effects on arthropod pests. There are no commercially available tomato cultivars that exhibit significant levels of resistance to arthropod pests.(More)
