Mosquitos carrying a greater number of malaria-causing parasites may be more likely to cause infection in the people they bite, according to a new study published in PLOS Pathogens.
More than 100 years have passed since scientists first discovered that infectious mosquitos inject malaria-caus... Read More
Vincent, Michael, and Michele explain the use of an electrochemical gradient to eliminate bacterial biofilms, and how phage susceptibility can be transferred by exchange of receptor proteins.
Greetings TWiM Team
Thinking about the revised estimates for the number of bacterial and human cells in the body from 10:1 to about 1:1, I was wondering what the microbiome cell to self cells ratio is for different species.
I pr... Read More
