The state of Piauí is in a Cerrado/Caatinga transition area, which is known the richness of its fauna and flora. Therefore, this work aims to know the diversity of fruit fly species in cashew orchards and native forest fragments in the south-central region of Piauí. Fruit flies were collected in McPhai...
Abstract Objective: To assess the antibacterial activity of Psidium guajava fractions and their effects on adhesion of a multispecies biofilm consisting of Streptococcus gordonii, Fusobacterium nucleatum, and Porphyromonas gingivalis in vitro. Material and Methods: Guava leaves were obtained from the m...

Abstract Xylella fastidiosa is a plant-pathogenic bacterium that lives inside host xylem vessels, where it forms biofilm which is believed to be responsible for disrupting the passage of water and nutrients. Pectobacterium carotovorum is a Gram-negative plant-specific bacterium that causes not only soft ...
Background: the current research studies why it is effective using Anrederacordifolia, Psidium guajava, and Pogostemon cablin by the local community as a traditional medicine for diarrhea treatment caused by Escherichiacoli bacteria. Objectives: We compared the inhibitor effectiveness...
Las infecciones respiratorias constituyen una importante causa de morbilidad y mortalidad a nivel mundial, incrementándose su relevancia ante la reciente infección por SARS-CoV-2, causante de la pandemia de COVID-19. Las opciones terapéuticas para esta infección respiratoria son escasas y sin eficaci...

La búsqueda de fuentes naturales para controlar los microorganismos es de interés en la producción de alimentos. Este estudio evaluó la composición química y la actividad antimicrobiana del aceite esencial de las hojas de Psidium cattleianum. El aceite esencial se extrajo por hidrodestilación y se...
Abstract Endodontic infections result from oral pathogenic bacteria which reach and infect dental pulp, as well as surrounding tissues, through cracks, unrepaired caries and failed caries restorations. This study aims to determine the chemical composition of essential oil from Psidium cattleianum leaves ...

Abstract This study evaluated the antibacterial and antiproliferative activities of the essential oil of Psidium guajava leaves (PG-EO), traditionally used in folk medicine. The essential oil was obtained from fresh leaves by hydrodistillation, using a modified Clevenger apparatus. The major PG-EO chemi...

This study aimed to evaluate how the surrounding vegetation affects the assemblage of fruit flies. For this, flies were collected in guava orchards with distinct types of surrounding vegetation (exotic pasture, native forest and fruit tree intercropping). The experiment was conducted in Itaporã and Dour...
Using nitrogen (N) to increase plant tolerance to salinity has been tested in many species. However, in addition to controversial results, most studies are conducted with annual species and/or in the initial growth stage and there are almost no studies with perennial fruit crops in the produ...
