Use of wild vertebrates for consumption and bushmeat trade in Brazil: a review.

Background: Bushmeat is a resource exploited by thousands of people around the world, especially in tropical and neotropical regions, constituting an important source of protein and income. But what is known, so far, about the consumption and trade of wild vertebrate meat (hereinafter "bushmeat") in a megadiverse country like Brazil? This question was answered through a systematic survey of publications on the consumption and trade of wild vertebrate meat made in Brazil between 2011 and 2021.

Methods: We selected 63 scientific articles available on "Google Scholar," "Science Direct," "Scopus," " Web of Science" and "Portal de Periódico da CAPES.

Food taboos and animal conservation: a systematic review on how cultural expressions influence interaction with wildlife species.

Background: Human societies have food taboos as social rules that restrict access to a particular animal. Taboos are pointed out as tools for the conservation of animals, considering that the presence of this social rule prevents the consumption of animals. This work consists of a systematic review that aimed to verify how food taboos vary between different animal species, and how this relationship has influenced their conservation.

Molecular junction by tunneling in 1D and quasi-1D systems.

We have investigated electron tunneling through two one-dimensional (1D) molecular junctions based on first-principles simulations using the density functional theory combined with the non-equilibrium Green's functions methodology. The first junction, composed of left and right carbyne wire electrodes with a sodium atom in between, is atomically thin. The second one is quasi-one-dimensional (quasi-1D) and consists of two single-wall carbon nanotube electrodes, closed on the tips and again a sodium atom in the scattering region.

GC-MS analysis of the fixed oil from Sus scrofa domesticus Linneaus (1758) and antimicrobial activity against bacteria with veterinary interest.

The bioprospection of zootherapeutic products can be a source of new drugs and to the creation of new strategies of natural resources conservation and management of endangered species. This fact is supported by ethnobiological studies indicating that the usage of zootherapeutic products can be replaced by the use of natural products isolated from plants and domestic animals. The emergence of antibiotic-resistant bacteria has increased the need for research for new active principles.

Antibacterial and antibiotic modifying activity evaluation of ruminants' body fat used as zootherapeutics in ethnoveterinary practices in Northeast Brazil.

Ethnopharmacological Relevance: Northeast Brazilian ethnoveterinary studies associated with the medicinal use of zootherapies have shown that ruminants' body fat such as sheep (Ovis aries), goats (Capra hircus) and cows (Bos taurus) are used in diseases affecting domestic animals.

Aim Of The Study: The objective of this study was to evaluate the antibacterial activity of the fixed oils from these ruminants in isolation and in association with antibiotics.

Results: Ovis aries (OFOA), Capra hircus (OFCH) and Bos taurus (OFBT) fixed oils were extracted using a Soxhlet apparatus with hexane as the solvent.

Body fat modulated activity of Gallus gallus domesticus Linnaeus (1758) and Meleagris gallopavo Linnaeus (1758) in association with antibiotics against bacteria of veterinary interest.

In the Northeast of Brazil, ethnoveterinary studies have shown that the body fat from Gallus gallus domesticus and Meleagris gallopavo are used for diseases that affect domestic animals. The objective of this study was to identify the chemical composition and to evaluate the antibacterial activity of the Gallus gallus domesticus (OFGG) and Meleagris gallopavo (OFMG) fixed oils in isolation and in association with antibiotics. The OFGG and OFMG from the poultry's body fat were extracted using hexane as a solvent in Soxhlet.

Antibacterial, modulatory activity of antibiotics and toxicity from Rhinella jimi (Stevaux, 2002) (Anura: Bufonidae) glandular secretions.

The increase in microorganisms with resistance to medications has caused a strong preoccupation within the medical and scientific community. Animal toxins studies, such as parotoid glandular secretions from amphibians, possesses a great potential in the development of drugs, such as antimicrobials, as these possess bioactive compounds. It was evaluated Rhinella jimi (Stevaux, 2002) glandular secretions against standard and multi-resistant bacterial strains; the effect of secretions combined with drugs; and determined the toxicity using two biologic in vivo models, and a in vitro model with mice livers.

Chemical identification and evaluation of the antimicrobial activity of fixed oil extracted from Rhinella jimi.

Context: The toad Rhinella jimi (Stevaux, 2002) (Bufonidae) is used in traditional medicine to treat a number of illnesses (inflammation, infections, and wounds) in humans as well as animals.

Objectives: The present work examined the antimicrobial actions of the extracted oils from the body fat of R. jimi (ORJ) against fungi and standard and multi-resistant lines of bacteria, as well as their effects when combined with aminoglycosides.

The trade in medicinal animals in northeastern Brazil.

Over the centuries, a significant part of the Brazilian fauna is widely sold, more specifically in retail stores or street markets. The objective was to characterize the sale of medicinal animals in five large northeast cities. Information about the sale of zootherapeutic items was obtained in the cities of Aracaju-SE, Fortaleza-CE, Maceio-AL, Recife-PE, and Salvador-BA.
