ABSTRACT
How clean is Your Water? The Isolation of Salmonella Growth within Chlorinated Biofilms in the Wastewater System
| Even water that looks clear and clean to you may have microorganisms
in it that might be harmful to your health. Salmonellosis is the number
one communicable disease in the U.S. and there are more than 2,000,000
cases reported annually. Salmonellosis is the infection that occurs in
humans and animals from the Salmonella bacteria (formally, Salmonella spp.).
The common symptoms are diarrhea, vomiting, abdominal pain, and nausea.
Salmonella has over 2,300 serotypes, and they all are pathogenic. The purpose
of this study is to understand how salmonella is becoming more resistant
to chlorination in the wastewater system in order for us to reduce salmonella
infections and outbreaks that come from waterborne diseases such as typhoid
fever and Salmonellosis.
In the experiment, samples of biofilms were collected from two chlorinated
stations at Ole Miss Water Treatment plant. After isolation and purification
of the bacteria strain from the Salmonella-Shigella and Tripicase Soy agar,
the result was that growth occurred mostly in the chlorinated stations
where the most chlorine was present.
