Inactivation of Streptococcus mutans genes lytST and dltAD impairs its pathogenicity in vivo

Journal of Oral Microbiology, 2019
Background: Streptococcus mutans orchestrates the development of a biofilm that causes dental caries in the presence of dietary sucrose, and, in the bloodstream, S. mutans can cause systemic infections.

Antibacterial activity of camel colostrum against pathogenic strain of Escherichia coli F17-associated with calf diarrhea

Open Veterinary Journal
Background: Many protective proteins, including lactoferrin and heavy chain antibodies, are present in camel colostrum, giving it a distinctive composition. Beyond a broad spectrum of pathogens, these proteins demonstrate antibacterial properties. Aim:

Environmental DNA profiling for detecting plant-insect interactions in endangered and native flora

Folia Oecologica
Environmental DNA (eDNA) is an established technique for studying plant-insect interactions, that has so far had very limited use in exploring flower-visiting insect communities.

Identification of Bicarbonate as a Trigger and Genes Involved with Extracellular DNA Export in Mycobacterial Biofilms

mBio, 2016
Extracellular DNA (eDNA) is an integral biofilm matrix component of numerous pathogens, including nontuberculous mycobacteria (NTM). Cell lysis is the source of eDNA in certain bacteria, but the source of eDNA remains unidentified for NTM, as well as for

Estimating shedding and decay rates of environmental nuclear DNA with relation to water temperature and biomass

Environmental DNA, 2020
Background  Environmental DNA (eDNA) analysis has been recently applied to the surveillance of species distribution and composition in aquatic ecosystems. However, most eDNA studies have used mitochondrial DNA markers, and those using nuclear DNA markers
