Potentially Probiotic Limosilactobacillus fermentum Fruit-Derived Strains Alleviate Cardiometabolic Disorders and Gut Microbiota Impairment in Male Rats Fed a High-Fat Diet.

High-fat diet (HFD) consumption is a risk factor for dyslipidemias, insulin resistance, and arterial hypertension linked with gut dysbiosis. Probiotic administration has been suggested as a safe therapeutic strategy for gut microbiota modulation and treatment and/or prevention of cardiometabolic disorders. Here, we assessed the effects of a potentially probiotic formulation containing strains of the Limosilactobacillus (L.

Live and ultrasound-inactivated modulate the intestinal microbiota and improve biochemical and cardiovascular parameters in male rats fed a high-fat diet.

This study aimed to evaluate the effects of ingestion of live (9 log CFU mL-1) and ultrasound-inactivated (paraprobiotic, 20 kHz, 40 min) Lacticaseibacillus casei 01 cells for 28 days on healthy parameters (biochemical and cardiovascular) and intestinal microbiota (amplicon sequencing of 16S ribosomal RNA) of rats fed a high-fat diet. Twenty-four male Wistar rats were divided into four groups of six animals: CTL (standard diet), HFD (high-fat diet), HFD-LC (high-fat diet and live L. casei), and HFD-ILC (high-fat diet and inactivated L.

WJL administration during pregnancy and lactation improves lipid profile, insulin sensitivity and gut microbiota diversity in dyslipidemic dams and protects male offspring against cardiovascular dysfunction in later life.

Background And Aim: Maternal dyslipidemia is recognized as a risk factor for the development of arterial hypertension (AH) and cardiovascular dysfunction in offspring. Here we evaluated the effects of probiotic administration of a specific strain of Lactiplantibacillus plantarum (WJL) during pregnancy and lactation on gut microbiota and metabolic profile in dams fed with a high-fat and high-cholesterol (HFHC) diet and its long-term effects on the cardiovascular function in male rat offspring.

Methods And Results: Pregnant Wistar rats were allocated into three groups: dams fed a control diet (CTL = 5), dams fed a HFHC diet (DLP = 5) and dams fed a HFHC diet and receiving L.

Survival of Lactobacillus acidophilus LA-5 and Escherichia coli O157:H7 in Minas Frescal cheese made with oregano and rosemary essential oils.

The effects of the incorporation of the essential oils from Origanum vulgare L. (OVEO; 0.07 μL/g) and Rosmarinus officinalis L.

Qualification of tropical fruit-derived Lactobacillus plantarum strains as potential probiotics acting on blood glucose and total cholesterol levels in Wistar rats.

Tropical fruit and their industrial processing byproducts have been considered sources of probiotic Lactobacillus. Sixteen tropical fruit-derived Lactobacillus strains were assessed for growth-promoting effects using a host-commensal nutrient scarcity model with Drosophila melanogaster (Dm). Two Lactobacillus strains (L.

Exploiting antagonistic activity of fruit-derived Lactobacillus to control pathogenic bacteria in fresh cheese and chicken meat.

This study assessed the antagonistic activity of fruit-derived lactic acid bacteria (LAB) strains against food-related bacteria and the effects of the highest organic acids LAB producers on the survival of Listeria monocytogenes and Salmonella Enteritidis PT4 in cheese and chicken meat, respectively. The production of organic acids by the Lactobacillus strains in the tested food matrices was also monitored. All tested LAB strains showed antagonistic activity in vitro on the growth of pathogenic or spoiling food-related bacteria, particularly on L.
