In situ delivery of passive immunity by lactobacilli producing single-chain antibodies

In situ gastrointestinal protection against anthrax edema toxin by single-chain antibody fragment producing lactobacilli

BACKGROUND Anthrax is caused by the bacterium Bacillus anthracis and is regarded as one of the most prominent bioterrorism threats. Anthrax toxicity is induced by the tripartite toxin complex, composed of the receptor-binding anthrax protective antigen and the two enzymatic subunits, lethal factor and edema factor. Recombinant lactobacilli have previously been used to deliver antibody fragments...

Lactobacilli-Expressed Single-Chain Variable

Vaginal Protection by H2O2-Producing Lactobacilli

Background: Peroxide-producing lactobacilli provide protection from infection for the female reproductive tract. However, in vitro studies demonstrated that H2O2-produced by Lactobacillus is not the cause of inhibition of pathogens. It is not exactly known how H2O2producing lactobacilli are involved in the protection of the vaginal environment. Objectives: This study aimed to evaluate the impor...

Antibodies testing, Immunity and immunity passport in Covid-19

The global outbreak of coronavirus disease-2019 (COVID-19) has affected most countries in the world. Our knowledge of diagnostic tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is evolving, and it is important to have a clear understanding of the nature of the tests and the interpretation of their findings. In this paper, the purpose is to interpret the results of two typ...
