The introduction and dissemination of pathogenic bacteria in the coastal waters of southern California and Mexico
Abstract
[Author's Abstract] I investigated the introduction and dispersion of potentially disease-causing bacteria in
the coastal waters of southern California and Mexico between March 16th and March 27th, 2012.
These bacteria can be transported into coastal waters via a number of pollution sources, and
studying their presence and abundance can be useful for assessing the safety of water for
recreational and fisheries uses. I found E. coli present in coastal waters near San Diego and
Cabo San Lucas, Mexico, and Staphylococcus aureus and methicillin resistant Staphylococcus
aureus (MRSA) present near Manzanillo, Mexico. The presence of S. aureus and MRSA could
pose health risks to recreational swimmers, especially individuals who are immunosuppressed or
individuals who have open cuts or abrasions.
