The infection of honey bees, Apis mellifera L. (Hymenoptera: Apidae), by the microsporidian Nosema ceranae is one of the factors related to the increase in colony losses and the decrease in honey production observed in r...

Background: Management of the coronavirus disease 2019 (COVID-19) pandemic caused by a novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) requires rapid and simple methods to detect COVID-19 patients and ...

Adhesion of symbiotic bacteria to host plants is an essential early step of the infection process that leads to the beneficial interaction. In the Bradyrhizobium diazoefficiens-soybean symbiosis few molecular determinant...

Kinetoplastid parasites, included Trypanosoma cruzi, the causal agent of Chagas disease, present a unique genome organization and gene expression. Although they control gene expression mainly post-transcriptionally, chro...

The capsid domain (CA) of the lentiviral Gag polyproteins has two distinct roles during virion morphogenesis. As a domain of Gag, it mediates the Gag–Gag interactions that drive immature particle assembly, whereas as a...

The aim of the present work was to determine the in vitro effect of Mentha piperita and Mentha pulegium essential oils against Echinococcus granulosus and to compare the effectiveness of both oils according to the exposu...

Autophagy is a well-conserved process of self-digestion of intracellular components. T. cruzi is a protozoan parasite with a complex life-cycle that involves insect vectors and mammalian hosts. Like other eukaryotic orga...

Vitamin D is an essential immune-modulator with receptors widely distributed throughout the body, and its serum levels fluctuate significantly among individuals between winter and summer months (from 30 to 50%). This stu...

Arbuscular mycorrhizal (AM) fungi and phosphate solubilizing bacteria (PSB) have a positive effect on plant productivity primarily through increasing phosphate availability. In order to study the interaction between AM f...

Water resources contaminated with wastewater are an important source for the dissemination of enteric viruses with an impact on the health of the population. The aim of the study was to assess the viral contamination of ...

The corn leafhopper, Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae), was considered a secondary pest in Brazilian corn crops. However, from 2015 onwards, there was a significant increase in its population a...

Abstract Felines are definitive hosts of Toxoplasma gondii and can shed oocysts in their feces, contaminating the environment. Sporulated oocysts are highly resistant to the environment and have higher infectivity, which...

El presente trabajo analiza económicamente las actividades tambo y agricultura en el sur de la provincia de Santa Fe. El período de análisis comprende los ciclos agrícolas de la serie 1993/94-2004/05. El modelo agrí...

Abstract Purpureocillium lilacinum is a nematophagous fungus used in biological control against some parasites, including Toxocara canis. This study researched the infectivity of embryonated T. canis eggs after exposure ...

Sistemas em aléias podem consistir numa solução para o uso da terra em regiões do Trópico Úmido. A relação dessa forma de manejo com a dinâmica dos fungos micorrízicos arbusculares (FMA) ainda é pouco compreen...

ABSTRACT Cutaneous leishmaniasis is a disease caused by protozoa of the genus Leishmania and, currently, the treatment of first choice is meglumine antimoniate. However, due to its limited effectiveness and high toxicity...

Zoonotic canine leishmaniosis, caused by Leishmania infantum, is a fatal disease worldwide in both humans and the reservoir host, dogs. The primary route of transmission is via sand fly bite. Vertical, transplacental, tr...

We evaluated the effect of carbendazim on non-target organisms using the parasite Chordodes nobilii as a test organism. The Gordiida act as a link between freshwater and terrestrial ecosystems; and C. nobilii, a neotropi...

Colombian isolate Bacillus sphaericus OT4b25 was tested for toxicity and pathology on rabbits and mice as mammalian models. After a high single dose of microorganism (10(8)-10(9) spores/ml) in four different tests that i...

Abstract The oocyst, a resistant form of Toxoplasma gondii, plays an important role in the transmission of this protozoan. The objective of this review was to report the methods capable of inactivating oocysts through a ...

This study evaluates the efficacy of the commercial product, Steinernema feltiae (NEMAPOM, e-nema GmbH, Germany), in controlling diapausing Cydia pomonella (Linneaus) (Lepidoptera: Tortricidae) (codling moth; CM) larvae ...

Baculoviruses are insect pathogens that are characterized by assembling the viral dsDNA into two different enveloped virions during an infective cycle: occluded virions (ODVs; immersed in a protein matrix known as occlus...

The innate immune response to West Nile virus (WNV) infection involves recognition through toll-like receptors (TLRs) and RIG-I-like receptors (RLRs), leading to establishment of an antiviral state. MiRNAs (miRNAs) have ...
