The use of antimicrobials as growth promoters and disease prevention is being constantly reduced in several animal production systems, including in the swine industry. Therefore, this study aimed to evaluate the effectiveness of using acidifiers to control Salmonella Typhimurium in 65-day-old pigs by det...

Objectives: The purpose of this study was to evaluate the mutagenic potential of fluoxetine and fluoxetine-galactomannan. Methods: Chromosomal aberration test and Salmonella typhimurium/microsome mutagenicity assay. Results: The results showed that fluoxetine (250 μg/mL) can cause chromosomal breaks of ...
Biosecurity, cleaning and disinfection of swine and poultry facilities are fundamental for the reduction of pathogenic microorganisms of importance for public and animal health. The objective of this work was to compare the levels of active ingredient described on the label and the real levels detected i...

BACKGROUND: Salmonella Typhimurium is a Gram negative pathogen that causes a systemic disease in mice resembling typhoid fever. During its infective cycle, S. Typhimurium is phagocytized by macrophages and proliferates inside a Salmonella containing vacuole where Salmonella is exposed and survives oxidat...
Resumen:
Introducción. La variante monofásica (1,4,[5],12:i:-) de Salmonella Typhimurium ocupa los primeros lugares en los programas de vigilancia de Salmonella a nivel mundial. En Colombia, Salmonella enterica variante monofásica alcanza el cuarto lugar en cuanto a los aislamientos clínicos recuper...
Synthetic preservatives are widely present in processed foods, but most of them have carcinogenic potential, requiring the development of new natural alternatives such as fruit extracts, for microbial control. The objective of the study was to evaluate the chemical characterization, antioxidant, and anti...

Origanum vulgare L. (OVEO) essential oil has been considered a candidate antimicrobial for use in food conservation systems. However, studies on the influence of concomitant variations of different food components or physicochemical parameters on the antibacterial properties of OVEO are scarce. This stud...

The 4-Hydroxycoumarin derivatives are known to show a broad spectrum of pharmacological applications. In this paper we are reporting the synthesis of a new series of 4-Hydroxycoumarin derivatives synthesized through Knovenegal condensation; they were characterized by using UV-Vis, FT-IR, NMR spectroscopi...
Resumen Introducción. La función inmunológica de las células dendríticas plasmacitoides durante las infecciones bacterianas, como la de Salmonella spp., es poco conocida. En ese contexto, se analizó su función efectora para presentar antígenos de Salmonella Typhimurium ante linfocitos T citotóx...
