Unlocking Probiotic Potential: Genomic Insights into Weissella paramesenteroides UFTM 2.6.1.

Weissella, a genus of lactic acid bacteria, has diverse beneficial attributes including probiotic activity and biotechnological applications. Therefore, the investigation of the Weissella genus has garnered growing interest. In this study, we sequenced the complete genome of Weissella paramesenteroides UFTM 2.

Microbiology of street food: understanding risks to improve safety.

Street foods play important socioeconomic and cultural roles and are popular worldwide. In addition to providing convenient and low-cost meals for urban populations, street food offers an essential source of income for vendors, especially women, and it can reflect traditional local culture, which is an important attraction for tourists. Despite these benefits, the microbiological safety of street food has become a worldwide concern because it is often prepared and sold under inadequate safety conditions, without legal control and sanitary surveillance.

Clinical isolates of E. faecalis and E. faecium harboring virulence genes show the concomitant presence of CRISPR loci and antibiotic resistance determinants.

In this study, we evaluated the antimicrobial susceptibility, the presence of gene-encoding virulence factors and CRISPR systems, as well as the ability to produce lytic enzymes among clinical E. faecalis and E. faecium isolates (n = 44).

Influence of Human Eating Habits on Antimicrobial Resistance Phenomenon: Aspects of Clinical Resistome of Gut Microbiota in Omnivores, Ovolactovegetarians, and Strict Vegetarians.

The use of xenobiotics in food production and how food intake is carried out in different cultures, along with different eating habits (omnivorism (ON), ovolactovegetarianism (VT), and strict vegetarianism (VG)) seem to have implications for antimicrobial resistance, especially in the human gut microbiota. Thus, the aim of this study was to evaluate aspects of the clinical resistome of the human gut microbiota among healthy individuals with different eating habits. Volunteers were divided into 3 groups: = 19 omnivores (ON), = 20 ovolactovegetarians (VT), and = 19 strict vegetarians (VG), and nutritional and anthropometric parameters were measured.

Assessment of vaginal microbiota in Brazilian women with and without bacterial vaginosis and comparison with Nugent score.

Introduction: Bacterial vaginosis (BV) is characterized by the depletion of Lactobacillus spp. population and increase of other species, especially Gardnerella vaginalis and Atopobium vaginae. This study aimed to investigate the vaginal microbiota structure of Brazilian women with and without BV according to Nugent Score and to assess the correlation among Nugent score and the quantification of BV-associated bacteria.

Kefir reduces insulin resistance and inflammatory cytokine expression in an animal model of metabolic syndrome.

There is growing evidence that kefir can be a promising tool in decreasing the risk of many diseases, including metabolic syndrome (MetS). The aim of the present study was to evaluate the effect of kefir supplementation in the diet of Spontaneously Hypertensive Rats (SHR) in which MetS was induced with monosodium glutamate (MSG), and to determine its effect on metabolic parameters, inflammatory and oxidation marker expression and glycemic index control. Thirty animals were used in this experiment.
