1. Presence of hyphae in chromoblastomycosis examinations: an enigma to be solved
Abstract The detection of muriform cells in direct mycological or anatomopathological examination is considered pathognomonic for chromoblastomycosis. The morphological aspect that these fungal structures acquire were called “Borelli spiders”, when associated with hyphae. Reports of this association have been described for decades, initially related to m

2. Chromoblastomycosis caused by Rhinocladiella aquaspersa: first case report in Guatemala
Abstract The authors report a case of 40-year-old male patient with a five-year history of chromoblastomycosis on his right leg. Diagnosis was performed by direct 40% KOH exam of skin scales, culture with micro- and macromorphologic analysis, and genotypic characterization (sequencing of a fragment of the ITS region and phylogenetic analysis) of the isolated

3. Alien spiders: First record of Loxosceles gaucho Gertsch, 1967 (Araneae: Sicariidae) in the Amazon region, Brazil
Abstract We present the first record for Loxosceles gaucho Gertsch, 1967 in the Amazonian region of Brazil. Four males, fifteen females and forty-nine immatures were collected in different places in Manaus, Amazonas, Brazil. This is the third species of Loxosceles reported in the Amazon region along with L. amazonica Gertsch, 1967, and L. similis Moenkhaus,

5. Esculent coating of spider silk enhanced the preservation and shelf life of apricot
Resumo Segundo a Organização para Alimentação e Agricultura (FAO), cerca de um terço do total de alimentos produzidos é perdido globalmente. A principal causa deste desperdício é a perecibilidade das frutas e legumes. Portanto, os pesquisadores têm se esforçado para desenvolver uma técnica de preservação eficaz. Nosso estudo explorou a potencial

6. Effects of copaiba oil on dermonecrosis induced by Loxosceles intermedia venom
ABSTRACT Background: Accidents caused by spiders of the genus Loxosceles constitute an important public health problem in Brazil. The venom of Loxosceles sp induces dermonecrosis at the bite site and systemic disease in severe cases. Traditional medicine based on plant-derived products has been proven to reduce the local effects of envenomation. The present

7. Diversity of soil spiders in land use and management systems in Santa Catarina, Brazil
Resumo: A capacidade de dispersão das aranhas em áreas contíguas (Arachnida, Araneae) está ligada diretamente às condições de manejo do solo. Objetivou-se com o presente trabalho estudar o efeito do sistema de uso do solo (SUS) sobre a abundância e diversidade das famílias de aranhas edáficas, bem como a relação dessas com os atributos físicos e

8. On the habitat use of the Neotropical whip spider Charinus asturius (Arachnida: Amblypygi)
ABSTRACT The non-random occupation of habitats is termed habitat selection. Some species of whip spiders select trees with burrows at their base, while others use substrates such as rocks. Here, we investigated the habitat use by Charinus asturius Pinto-da-Rocha, Machado & Weygoldt, 2002, an endemic species of Ilhabela Island in Brazil. We found that C. astu

9. The breeding biology and nest success of the Short-tailed Antthrush Chamaeza campanisona (Aves: Formicariidae) in the Atlantic rainforest of northeastern Brazil
ABSTRACT We present the results of a 26-year study on the breeding biology of the Short-tailed Antthrush, Chamaeza campanisona (Lichtenstein, 1823) in an Atlantic rainforest remnant of northeastern Brazil (Alagoas/Pernambuco). We followed the fate of 38 nests, of which 19 failed, 11 succeeded and 8 had an unknown fate. The presence of most nests coincided wi

10. Does urbanization have positive or negative effects on Crab spider (Araneae: Thomisidae) diversity?
ABSTRACT Urbanization has a great impact on the diversity of living organisms. Spiders, for example, have been shown to respond negatively (some orb weaving species) and positively (ground dwelling species) to urbanization. The effects of urbanization on crab spiders (Thomisidae) (sit-and-wait predators that generally ambush their prey on flowers and leaves)

11. Highlights in the knowledge of brown spider toxins
Abstract Brown spiders are venomous arthropods that use their venom for predation and defense. In humans, bites of these animals provoke injuries including dermonecrosis with gravitational spread of lesions, hematological abnormalities and impaired renal function. The signs and symptoms observed following a brown spider bite are called loxoscelism. Brown spi

12. Infrared thermography to diagnose and manage venomous animal bites and stings
Abstract INTRODUCTION Infrared imaging (IR) is a noninvasive technique that quantifies body surface temperature, producing a digital color image. IR has been used to study diseases in which skin temperature can reflect the presence of inflammation. METHODS This was an observational pilot study of eight patients envenomed by snakes, spiders, and scorpions
