About This Project

Antibiotic resistance, a global concern, is a significant health issue of animals and humans. Resistant bacteria, a growing presence in marine life, are derived from land via humans, animals, and agriculture. This is particularly troubling. Are resistant bacteria present in marine mammals of an urban ecosystem, the Salish Sea, in Washington State? We will sample dead locally stranded harbor seals and porpoises to detect resistant bacteria and their possible linkages to land sources.

Join The Discussion

What is the context of this research?

Antibiotic resistant bacteria are documented in various marine species, though most wild animals have never been exposed to antibiotics. Resistance may be created when wastewater discharge, that carries antibiotics and resistant bacteria into terrestrial waterways, finds its way to the marine coastline where it can cause infectious disease in marine organisms. This is important from a "One Health" perspective which recognizes that the health of animals, humans, and the environment linked together. When resistant bacteria are introduced to animals or their environment, the animals may themselves become sick, develop further resistance, or they may become a reservoir and transfer the bacteria and resistance to humans and the environment.

What is the significance of this project?

Information on antibiotic resistance in marine species in Washington state's inland waters, also known as the Salish Sea is limited. Preliminary work reported resistance in young stranded harbor seals in rehabilitation (Lockwood et al. 2006) and in local endangered southern resident killer whale (orca) breath (Raverty et al. 2017). A larger dataset with multiple species, age classes, and locales is needed to determine if resistant bacteria exhibit patterns within this urban marine ecosystem and if they might pose a threat to marine mammal health, including that of the orcas NOAA Fisheries West Coast Region - Killer whale information page. Study results will inform local human and veterinary health officials, as well as raise public awareness of drug resistance.

What are the goals of the project?

The objective of this study is to evaluate the presence and distribution of antibiotic-resistant bacteria in Salish Sea marine mammals. Specifically we will:

1) describe the presence and extent of antibiotic-resistant bacteria

2) determine differences in resistance between seals and porpoises

3) determine geographic patterns

We will collect fresh dead-stranded harbor seals and harbor porpoises (69 each species; total =138), perform autopsies, and swabs of the inside of the large intestine and any noted lesions during autopsy. Bacterial colonies that grow in the lab will be tested for susceptibility (or resistance) to a suite of commonly used antibiotics in veterinary and human medicine. Read more details about our antibiotic sensitivity testing protocol under the Methods section.

Budget

Please wait...

The majority of this funding ($5800) is allocated towards the actual cost of running the bacterial cultures and antibiotic sensitivities analyses for approximately 138 samples ($42/sample) to be collected over a year in roughly equal numbers of seals and porpoises as well as between northern and southern sampling regions. The culture swabs and transport costs are included in the per-sample cost.

$1000 in funding will be allocated time towards analyzing the culture and sensitivity data.

To support an educational and public outreach component, we will allocate $100 to produce an informational hand-out to be distributed at scientific and stakeholder meetings, as well as at local venues and events focused on the environment. An electronic version will be post on Orca Network's website to help share our findings and increase awareness about the problem of antibiotic resistance in the marine environment.

An additional $100 will be allocated to cover any unforeseen small supply needs.

This is a fantastic project to undertake and I fully support it and the abilities of Dr Norman having worked with her via the MARVET programme. It is essential we continue to research and undertand the links between animal, environment and human health which we refer to as “one health, one medicine" and investigate these species as suggested in this study as bio-indicators concerning current or potential negative impacts ultimately affecting human and animal health.
As a practicing small animal/exotics/wildlife veterinarian, I feel this project is of great worth. Antibiotic resistance is a huge problem in all aspects of medicine and I feel that this project, with its relatively low tech but brilliant approach is very worth funding.

Flag iconProject Timeline

The project plan for Year 1 is to collect the samples from stranded harbor seals and harbor porpoises within the Salish Sea of Washington state over a year's time beginning in early October 2018. During Year 2 we will compile, analyze, and summarize the results of the culture and antibiotic sensitivity testing. The study results will be written up for submission to a peer-reviewed journal. The informational hand-out will also be completed during Year 2.

Team Bio

The team members combined have more than 30 years' experience with marine species and diseases. They are very passionate about marine ecosystem health and have worked collaboratively on a number of projects related to marine mammal health. Various skills such as veterinary medicine, biology, statistical, data analyst, and project management come together in this project. As a team, we are intimately familiar with the targeted species in this project, as well as the geographical landscape.

Stephanie Norman

I am a wildlife epidemiologist and veterinarian in the Pacific Northwest. I received veterinary degree from Texas A&M University, a Master of Science in epidemiology from the University of Washington, Seattle, and a PhD in wildlife epidemiology from the University of California, Davis. Since 1999, I have been involved in the investigation of health and diseases of marine animals for various organizations and agencies. An admirer of all ocean life, my research and epidemiologic work covers marine life of all sizes, from corals to top level predators. My areas of interest include understanding and interpreting aspects of ocean health, including pathogen transmission in the marine environment, as well as those of concern to human/public health. I am also interested in quantifying inherent differences in species susceptibility as well as the effects of natural and human-related stressors on outcomes of marine diseases. The basis of my research efforts is to be able to provide the knowledge needed to help mitigate human impact on marine species and raise awareness of ocean health and the connection to human health.

You can view more about my work and publications on my website at www.marine-med.com, follow me on Facebook @MarineMed1 and on Twitter @whaledocsteph.

Sandra M. Dubpernell

Sandra Dubpernell, MS

After recovering from a massive infection from a ruptured appendix as a small child, I became intrigued by diseases and their causes.

I pursued this interest in college (Gettysburg) and grad school (Fairleigh Dickinson University) and received a Masters of Science degree. After spending 30 years in a laboratory testing for viruses, I relocated to Whidbey, volunteered for investigating dead marine mammals and joined the Central Puget Sound Marine Mammal Stranding Network in 2002. Since then I have assisted Dr. Stephanie Norman in hundreds of necropsies on seals, sea lions, porpoises and gray whales by collecting samples and recording the necropsy findings via written and photographic reports. I have been included on scientific papers published by Dr. Stephanie Norman but have not been principal author on any.

I do maintain an archive of the thousands of documents and images that the CPSMMSN has created during the past 16 years.
