UrduScientists at Children’s Hospital of Philadelphia (CHOP) have identified two proteins that could be used for a potential vaccine against nontypeable Haemophilus influenzae (NTHi). Working in a mouse model, the investigators found that administering two bacterial adhesive proteins that play a key role in helping the bacteria to latch on to respiratory cells and initiate respiratory tract infection stimulated protective immunity against diverse NTHi strains, highlighting the vaccine potential.

Using nanobodies to block a tick-borne bacterial infection
Tiny molecules called nanobodies, which can be designed to mimic antibody structures and functions, may be the key to blocking a tick-borne bacterial infection that remains out of reach of almost all antibiotics, new research suggests.
Escape Artists: How Vibrio Bacteria Break Out of Cells
DALLAS – Aug. 18, 2020 – As soon as the foodborne pathogen Vibrio parahaemolyticus infects a human intestinal cell, the bacteria are already planning their escape. After all, once it is in and multiplies, the bacterium must find a way out to infect new cells.
A wound dressing that kills bacteria
In order to combat bacterial wound infections, Empa researchers have developed cellulose membranes equipped with antimicrobial peptides. Initial results show: The skin-friendly membranes made of plant-based materials kill bacteria very efficiently.
Targeting the cancer microenvironment
The recognition of bacterial infections or foreign substances is mediated and controlled by the human immune system. This innate and adaptive immune system comprises the most important metabolic and cellulare processes to fight against infections and other diseases.
Color-changing bandages sense and treat bacterial infections
Researchers reporting in ACS Central Science have developed color-changing bandages that can sense drug-resistant and drug-sensitive bacteria in wounds and treat them accordingly.
