The objective of this study was to compare the effects incorporation microcapsules or nanoemulsions with Opuntiaoligacantha on quality fresh cheese. Three treatments were established: Control, cheese (Micro), and nanoemulsion (Nano). parameters evaluated physicochemical (moisture, ash, fat, proteins, pH), microbiological (mesophilic aerobic bacteria, mold–yeast, total coliforms), functional (total phenols, flavonoids, antioxidant capacity), texture (hardness, elasticity, cohesion, chewiness)...

Cactus acid fruit (Xoconostle) has been studied due its content of bioactive compounds. Traditional Mexican medicine attributes hypoglycemic, hypocholesterolemic, anti-inflammatory, antiulcerogenic and immunostimulant properties among others. The compounds contained in xoconostle have shown their ability to inhibit digestive enzymes such as α-amylase α-glucosidase. Unfortunately, polyphenols antioxidants general are molecules susceptible degradation storage conditions, (temperature, oxygen...

In Mexico, bullfrogs (Lithobates catesbeianus) are produced as gourmet food. However, can be carriers of pathogens because the frogs' preferred living conditions occur in stagnant water. The present study aimed to identify bacteria that cause foodborne diseases or associated with human diseases. For molecular identification, based on sequential analysis by 16S rRNA rpoD was conducted all isolates obtained from bullfrog. A total 91 bacterial were bullfrogs; 14 genera and 23 species...

Parasitic diseases of pigs are a public and veterinary health problem. Helminths influence pork production, whereas backyard can transmit these parasites.

Wild boars (Sus scrofa) were introduced in Mexico for sport hunting and meat trading human consumption, but the available data regarding their role pathogen transmission are limited. This research field work aimed to identify helminths of wild boar produced three units conservation management sustainable use wildlife placed eastern economic region Mexico. Samples feces serum collected from 90 animals that came different ranches. Stool examination antibody determination Fasciola hepatica,...

Aquaculture parasite biodiversity dependents on multiple environmental characteristics, including water quality. The analysis of this relationship aims to support improvements in the production management tilapia. For purpose, a total 100 juvenile fishes (Oreochromis spp.) and 30 samples were collected at Valle del Mezquital Central-Eastern socioeconomical region Mexico. A study was carried out quality parameters determined. Biodiversity habitat measured using Simpson diversity index, which...

Honey has long been used as a food and reported to have potential health benefits. In this work, total phenol content, colour antioxidant hepatoprotective activities of honey samples different floral origins from the State Hidalgo, Mexico were explored using in vitro assays. Hepatoprotective activity was measured by inhibitition β-glucuronidase; gastroprotective determined inhibition urease; evaluated 2,2'-Azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) 2, 2-diphenyl-1-picrylhydrazyl...

Eimeria pileata Soriano-Vargas, Medina, Salgado-Miranda, García-Conejo, Galindo-Sánchez, Janczur, Berto and Lopes, 2015 is a junior homonym of Straneva Kelley, 1979 needs to be replaced. This coccidium was described from rufous-capped brush finch Atlapetes pileatus Wagler in the Nevado de Toluca Natural Protected Area, Mexico. Thus, maintain original intent specific epithet derived scientific name type-host, atlapetesi nom. nov. proposed as replacement name. Additionally, current work...

Abstract Anisakisspp. nematodes are potentially zoonotic parasites; that infects a wide variety of aquatic species worldwide, with marine fish being the paratenic hosts. The aim study was identify presence Anisakidae nematodes, and other parasites in Mugil curema . A total 96 M obtained from local markets Tulancingo, Hidalgo, Mexico, were analyzed by necropsy. Only five present nematode collection epaxial muscle. tissues highest prevalence identified, samples muscle larval migration...

A lo largo de la historia del hombre, los animales han desempeñado un papel fundamental para el desarrollo las poblaciones sin excepción conejos. Durante periodo geológico Pleistoceno y Holoceno, se ha considerado aparición conejo europeo (Oryctolagus cuniculi). Y durante Epipaleolítico, Mesolítico Neolítico en Península Ibérica suroeste Francia, conejos fueron ampliamente explotados. Por otra parte, México, ciudad prehispánica Teotihuacan (1-550d.C.) clásico (200-600d.C:), cuenca existe...

We study the kinetics of eosinophils during development cellular infiltrate surrounding nurse cell Trichinella spiralis (T. spiralis) in experimentally infected mice. Male CD1 mice were with 50 viable muscle larvae MSUS/MEX/91/CM-91 T. strain. Tongues and diaphragms obtained daily from days 13 to 39 post infection. Diaphragms compressed subjected Giemsa stain. histologically sectioned stained erythrosine B or hematoxylin eosin. The cell-larva complex detected by optical microscopy since day...

Objetive. Expose nematodes of the Anisakidae family to different aqueous extracts and identify with nematicidal capacity. Material methods. The concentrations bioactive compounds epazote (Dysphania ambrosioides), onion (Allium cepa), siempre viva (Kalanchoe pinnata) xoconostle (Opuntia oligacantha) were identified. Live parasites obtained from Lisa fish (Mugilidae), be exposed extracts. Results. K. pinnata O. oligocantha presented a higher concentration components polyphenols, flavonoids...

Heat stress and a high metabolic rate of broilers increase the production reactive oxygen species, which must be removed by antioxidants to prevent oxidative stress. Selenium (Se) is potent antioxidant as it structural part glutathione peroxidase (GPx). Dietary supplementation Se can help reduce caused heat-stress conditions. The aim was evaluate effect on performance status under heat stress, using meta-analysis approach, quantify contribution heterogeneity explanatory variables through...

The Cattle Egret (Bubulcus ibis) is an avian species native to Africa that has the ability adapt different habitats, environmental characteristics, and available food sources. We collected a total of 2,400 excreta from four resting colonies during months January March 2020, in region Tulancingo de Bravo, Hidalgo, Mexico; order identify elements make up diet Egret. Samples were placed 70% alcohol, later analysed with stereoscopic microscope. identified 1,677 items 16 taxonomic entities could...

The genus Aeromonas is a group of bacteria that widely distributed in water bodies and belongs to the normal intestinal microbiota aquatic terrestrial animals. In present work, rainbow trout fingerlings were experimentally infected by an immersion bath with different species. Subsequently, behavior groups was observed recorded. Infected evaluated histopathology. highest percentages hyperpigmentation (18.88%) inappetence (47.7%) fish A. salmonicida, while abnormal swimming (83.33%) recorded...

Escherichia coli is an important microorganism as intestinal microbiota of animals and humans, so its presence in food serves indicator possible fecal contamination; some strains can cause disease, mainly due to the consumption water animal contaminated. The objective this study was detemine resistance antimicrobials genetic character E. present carcasses feces bovines killed slaugtherhouses, know epidemiological panorama Mexico. carried out 32 three municipal slaugtherhouses (A, B C)...
