Enhancing Probiotic Performance in Food Matrices: From Strain Selection to Bioengineering

Journal of Food Science, Volume 91, Issue 8, August 2026.
ABSTRACT Probiotics are central to functional food innovation, but their application is limited by viability loss during processing, storage, and gastrointestinal (GI) transit. A key insight is that viability and functionality are distinct attributes; maintaining high cell counts does not guarantee that probiotics retain their beneficial properties ...

The Impact of the Vaginal Microbiome and Microbial Metabolites on HIV Transmission at the Female Reproductive Tract Epithelial Barrier

American Journal of Reproductive Immunology, Volume 96, Issue 2, August 2026.
ABSTRACT Despite major advances in biomedical HIV prevention strategies, almost 50% of the 1.3 million new HIV infections in 2024 occurred in women and girls through heterosexual transmission. Choice in HIV prevention modalities is needed throughout a women's lifespan to increase pre‐exposure prophylaxis uptake; however, there is a paucity of topical ...

Elucidating the Staphylococcus aureus TSST‐1 Regulatory Network as a Response to Vaginal pH

Molecular Microbiology, Volume 126, Issue 2, Page 220-235, August 2026.
Toxic shock syndrome toxin‐1 (TSST‐1) is a potent Staphylococcus aureus superantigen responsible for menstrual toxic shock syndrome (mTSS). Regulation of TSST‐1 is controlled by multiple systems including the stand‐alone transcriptional regulators CcpA and SarA and two‐component systems including the redox sensor SrrAB, the membrane stress sensor SaeRS,

Genetic Toolbox Expansion Enables Constitutively Fluorescent Lacticaseibacillus rhamnosus for Functional Microbiome Research

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
We expanded the genetic toolkit for Lacticaseibacillus rhamnosus by enabling direct cloning, and leveraging five constitutive promoters and a repressor system. Fluorescent L. rhamnosus strains with different fluorochromes engineered with the high‐performing PtlpA promoter demonstrated functionality in microbial competition assays, supporting microbiome

Milk and Dairy Consumption and Its Relationship With Abundance of Lactobacillus crispatus in the Vaginal Microbiota: Milk Intake and Vaginal Lactobacillus

, 2023
Objectives Diet habits, such as low milk and dairy intake, have been associated with bacterial vaginosis. Thus, the authors compared vaginal Lactobacillus crispatus abundances in women with different molecularly defined community state types (CSTs ...

HIV Transmission and Immunology of the Male Reproductive Tract

American Journal of Reproductive Immunology, Volume 96, Issue 1, July 2026.
ABSTRACT The penile epithelium, encompassing multiple anatomical sites, is the primary location of human immunodeficiency virus (HIV) acquisition in heterosexual men. Although the per‐contact risk of penile HIV acquisition is generally low, substantial global discrepancies in HIV prevalence still exist, particularly in low‐income regions.
