Lactobacillus fermentum MCC2760 attenuates neurobehavioral alterations induced by oxidized oils in rats.

The common practice of reusing deep-fried oil may derange the ability of the brain to counter free radicals and inflammatory responses and can adversely alter neurobehavioral changes. In this study, we elucidated the modulatory potentials of Lactobacillus fermentum MCC2760 (LF) on neurobehavioral changes induced by dietary intake of oxidized oils. Female Wistar rats were fed with AIN-76 diets containing native sunflower oil (N-SFO), native canola oil (N-CNO), heated sunflower oil (H-SFO), heated canola oil (H-CNO), heated sunflower oil with probiotic (H-SFO + LF) or heated canola oil with probiotic (H-CNO + LF} for 60 days.

The Occurrence of Colistin Resistance in Potential Lactic Acid Bacteria of Food-Producing Animals in India.

The overuse of colistin, the last-resort antibiotic, has led to the emergence of colistin-resistant bacteria, which is a major concern. Lactic acid bacteria which are generally regarded as safe are known to be reservoirs of antibiotic resistance that possibly pose a threat to human and animal health. Therefore, this study assessed the prevalence of colistin antimicrobial resistance in livestock in India, that is lactic acid bacteria in healthy chickens, sheep, beef, and swine of Mysore.

Dark chocolate: delivery medium for probiotic NCIM 5671.

fermentation of glycosaminoglycans from mackerel fish waste and its role in modulating the antioxidant status and gut microbiota of high fat diet-fed C57BL/6 mice.

Bioactive polysaccharides such as glycosaminoglycans (GAGs) exhibit potential health benefits for several health complications including obesity. The gut microbiota plays a key role in regulating host metabolism, nutrition and immunity. The present work assessed the potential of extracted GAGs (e-GAGs) in maintaining the gut microbiota and ameliorating the effects of high fat diet in and models.

Lactobacillus fermentum MCC2760 abrogate high-fat induced perturbations in the enterohepatic circulation of bile acids in rats.

Aim: This study in hyperlipidemic rats elucidated the effect of Lactobacillus fermentum MCC2760 on intestinal bile acid (BA) uptake, hepatic BA synthesis, and enterohepatic BA transporters.

Main Methods: Diets rich in saturated fatty acids [coconut oil (CO)] and omega-6 fatty acids [sunflower oil (SFO)] at 25 g fat/100 g diet were fed to rats with or without MCC2760 (10 cells/kg body weight).

A machine learning-based approach to determine infection status in recipients of BBV152 (Covaxin) whole-virion inactivated SARS-CoV-2 vaccine for serological surveys.

Data science has been an invaluable part of the COVID-19 pandemic response with multiple applications, ranging from tracking viral evolution to understanding the vaccine effectiveness. Asymptomatic breakthrough infections have been a major problem in assessing vaccine effectiveness in populations globally. Serological discrimination of vaccine response from infection has so far been limited to Spike protein vaccines since whole virion vaccines generate antibodies against all the viral proteins.

Prevalence of polymyxin resistance through the food chain, the global crisis.

Antimicrobial resistance is one of the vital challenges facing global health today. Multi-drug resistant (MDR) infections are often treated with the narrow-spectrum drugs, colistin (polymyxin E) or polymyxin B, which are last-resort antibiotics for human therapeutics that are effective against Gram-negative bacteria. Unfortunately, resistance to these polymyxins has occurred because of selective pressure caused by the inappropriate use of those antibiotics, especially in farming.
