Engineering Adhesion of the Probiotic Strain Nissle to the Fungal Pathogen .

Engineering live biotherapeutic products against fungal pathogens such as has been suggested as a means to tackle the increasing threat of fungal infections and the development of resistance to classical antifungal treatments. One important challenge in the design of live therapeutics is to control their localization inside the human body. The specific binding capability to target organisms or tissues would greatly increase their effectiveness by increasing the local concentration of effector molecules at the site of infection.

Drosophila melanogaster establishes a species-specific mutualistic interaction with stable gut-colonizing bacteria.

Animals live together with diverse bacteria that can impact their biology. In Drosophila melanogaster, gut-associated bacterial communities are relatively simple in composition but also have a strong impact on host development and physiology. It is generally assumed that gut bacteria in D.

Modification of membrane cholesterol and its impact on frozen-thawed chicken sperm characteristics.

This study was conducted to determine the changes in chicken sperm plasma membranes fluidity and polarity as lipid packing arrangement induced by cholesterol-loaded cyclodextrin (CLC) and 2-hydroxypropyl-β-cyclodextrin (HBCD) and how sperm cryopreservation outcomes are improved by these changes. Treatment with 2 mg HBCD supported the highest (P < 0.01) percentage of viable spermatozoa compared with the control and CLCs groups after cryopreservation.
