Madslien found a high prevalence of bacteria of the genus Bartonella spp. both in the moose's blood and in the keds themselves.
Whereas moose outside the distribution range of the ked were infected with only one type of Bartonella bacterium moose inside the distribution range were infected with two different Bartonella bacteria.
These findings indicate that moose are a reservoir for Bartonella spp . and that deer keds act as vectors for Bartonella bacteria infections.
However it is not yet clear to what degree these bacteria can cause disease. Measuring the stress hormone cortisol in the moose's coat was used as a method for appraising the long-term effect of the deer ked on the health
The findings show how a simple mechanism allows an insect the pea aphid to regulate the manufacturing of essential nutrients supplied by its symbiotic bacteria called Buchnera aphidicola.
To help answer this question the researchers looked at amino acids that are fundamental to the pea aphid-Buchnera symbiotic function.
which is made in Buchnera and it's deficient in the pea aphid's diet. Glutamine is ferried across a membrane that surrounds the cells where the bacteria lives by an amino acid transporter named Apglnt1.
