A key goal in the control of canine visceral leishmaniosis (CVL) has been the development of vaccines with a highly protective capability to interrupt the parasite transmission cycle. However, in addition to promising vaccine searches, researchers have sought to develop new drugs capable of eliminating parasites in humans and dogs. With that in mind, this study analyzed an immunotherapeutic approach in dogs naturally infected with Leishmania infantum. Fourteen dogs were divided into two groups and ...

Melon cultivation is frequently heavily reliant on synthetic fungicides, including products used to control gummy stem blight caused by Stagonosporopsis cucurbitacearum. The essential oils used in controlling plant pathogens may offer an alternative to chemical pesticides. This study evaluated the effectiveness of essential oils to control the gummy stem blight in melon plants. In vitro tests were carried out using essential oils obtained from ripe noni fruit (Morinda citrifolia) and dehydrated leaves ...

Plant essential oils are promising tools for the management of insect infestations in stored beans. However, how these biorational products exert their insecticidal actions remains unknow. Here, we evaluated the insecticidal and repellent potential of Bursera graveolens essential oil against the bean weevil species Acanthoscelides obtectus and Zabrotes subfasciatus. By using chemical and in silico analyses, we evaluated the molecular interactions of the essential oil constituents with two potential ...

Due to the production facilities and great functionalities, the starch extracted from Cassava plants' (Manihot esculenta Crantz) roots is one of the most abundant and inexpensive raw materials used in food- and non-food industries. The utilization of starches to encapsulate plant essential oils is a relevant advance in the control of insect pests, including mosquitoes that transmit human diseases. The starch-based microencapsulation of essential oils reduces the degradation and volatilization of ...

Abstract Biorational insecticides are composed of natural products, including animals, plants, microbes, and minerals, or are their derivates. The use of biorational products for the management of insect pests has grown intensively in recent years, which has increased their popularity and share on the insecticide global market. Much of these recent increases in the use of biorational insecticides has been derived from the generalized perception that conventional insecticides have undesirable ecological ...

The plant-based biopesticides have been proposed as insect pest control tools that seem to be safer for the environment and human health when compared to synthetic conventional molecules. However, such assumptions are generally made without considering the absence of detrimental effects on sublethally-exposed non-target organisms or showing the physiological basis of the selective action of such botanical products. Thus, by using in silico-based and in vivo toxicological approaches, the present ...

The increasing prevalence of resistance to conventional antibiotics in pathogenic bacteria has demanded faster development of novel sources of antibacterial agents. In this context, biological activities shown by natural compounds have received particular attention. One of the alleged backslashes for these alternative bactericidal tools is the current knowledge gap regarding their action mechanisms. Here, we evaluated the activity of essential oil extracted of Negramina, Siparuna guianensis, plants ...

Fumonisins are mycotoxins (MTs) produced mainly by the fungus Fusarium verticillioides, the main pathogens of maize which cause ear rot. The aim of this work was to evaluate some factors that may lead to high fumonisin production by F. verticillioides in maize grains, correlating the pathogen inoculation method with different genotypes grown in four Brazilian states. Experiments were conducted in 2015-2016 in maize crops from experimental maize fields located in four distinct states of Brazil. Results ...

Abstract Although the cultivation of transgenic plants expressing toxins of Bacillus thuringiensis ( Bt ) represents a successful pest management strategy, the rapid evolution of resistance to Bt plants in several lepidopteran pests has threatened the sustainability of this practice. By exhibiting a favorable safety profile and allowing integration with pest management initiatives, plant essential oils have become relevant pest control alternatives. Here, we assessed the potential of essential oils ...

Phytase plays a prominent role in monogastric animal nutrition due to its ability to improve phytic acid digestion in the gastrointestinal tract, releasing phosphorus and other micronutrients that are important for animal development. Moreover, phytase decreases the amounts of phytic acid and phosphate excreted in feces. Bioinformatics approaches can contribute to the understanding of the catalytic structure of phytase. Analysis of the catalytic structure can reveal enzymatic stability and the polarization ...
