Paratuberculosis is an infectious-contagious disease caused by the bacterium Mycobacterium avium subspecie paratuberculosis (MAP), which affects the digestive tract of ruminants. MAP is distributed worldwide; however, there are no publications on the seroprevalence of this disease in cattle in Sonora State. Therefore, the objective of this study wa...

Rehabilitating degraded arid lands requires overcoming biotic and abiotic limitations. The objective of this study was to determine if low-cost protective shelters improve the survival and growth of palo verde (Parkinsonia microphylla) plants during the first year of reforestation at degraded sites in the Sonoran Desert. Protective shelters were bu...

En la industria pecuaria es importante mantener al ganado en buen estado de salud para alcanzar niveles adecuados de producción. En la actualidad, el uso de antibióticos para el control de infecciones es limitado, debido a la resistencia de los microorganismos a estos fármacos. Por otro lado, los insecticidas y repelentes de origen sintéticos conti...

Introduction: Giardia lamblia, a protozoan intestinal parasite is able to evade or suppress defense mechanisms, such as innate response. Antigen presenting cells (APC) like dendritic cells may orchestrate an immune response and support a more effective adaptive defense. Conjugated linoleic acid (CLA), a dietary lipid, has shown biological activity...

Antigen-presenting cells (APCs) are strategically placed in all anatomic sites with high antigen exposure such as the respiratory system. The aim of this study was to evaluate phenotypic and functional properties of APCs from the lung (L-Cs), mediastinal lymph node (LN-Cs) and bronchoalveolar lavage cells (BAL-Cs). The APCs were first analyzed base...

A cross-sectional study was conducted to evaluate the transmission of swine influenza through occupational exposure and to assess some risk factors for zoonotic transmission in workers from commercial farms in Mexico. Seroprevalence to swine influenza subtypes was determined by hemagglutinin inhibition assay and was higher in exposed (E), in compar...

A two-year survey was carried out on the occurrence of avian influenza in migrating birds in two estuaries of the Mexican state of Sonora, which is located within the Pacific flyway. Cloacal and oropharyngeal swabs were collected from 1262 birds, including 20 aquatic bird species from the Moroncarit and Tobari estuaries in Sonora, Mexico. Samples w...
