Hello, my name is Maria King.
I am an associate professor
at the Department
of Biological and
Agricultural Engineering
at Texas A&M University
in College Station, Texas.
We are here with my doctoral
student, Brooke Smith,
to present our
studies focusing on
environmental
factors that trigger
antibiotic resistance
in bacteria.

In this presentation,
we will first define
bioaerosols and explain
their importance.
Then, go through cellular
stress responses
to the environment,
including responses
in gene expression,
protein activity, and
cellular metabolism.
Followed by antibiotic and
antimicrobial resistance,
and the significance
and future of our work.

First, we will
define bioaerosols.

Bioaerosols are small
airborne particles,
usually less than 100
micrometers in size,
that can come from various
biological sources,
such as plants,
animals, and microbes.
These sources can release
plant matter such as pollen,
or animal matter such as dander,
and microorganisms
themselves, or
toxins they produce,
or genetic materials.
In this presentation,
we will be focusing
primarily on bioaerosols
from microorganisms.
Bioaerosols can be
living or non-living,
but they originate
from living sources.
We can also find
bioaerosols everywhere,
inside of our homes, hospitals,
classrooms, or outside
on farms, over oceans.
Anywhere where there is air,
there will be aerosols
and bioaerosols.
They are not restricted
to a location.
The aerosols can
travel as little as
a few micrometers to kilometers.
One of the main reasons
we are conducting
our research is because
bioaerosols can cause infections,
respiratory diseases,
allergies, and cancer.
