Extensive flooding had the potential to mobilize microbial contaminants from a variety of sources. Our study evaluated microbial contaminants in surface waters at 40 sites across Eastern North Carolina 1 week after the hurricane made landfall (Phase 1) and one month later (Phase 2). High concentrations of Escherichia coli were detected in flowing channel and floodwater samples across both phases; however, channel samples during Phase 2 had higher concentrations of E. coli compared to Phase 1. Human- and swine-associated fecal markers were detected in 26% and 9% of samples, respectively, with no trends related to phase of sampling. Arcobacter butzleri was previously shown to be recovered from most (73%) samples, and detection of this pathogen was not associated with any source-associated fecal marker. Detection of Listeria spp. was associated with the swine-associated fecal marker. These results suggest that improved swine and human feces management should be explored to prevent microbial contamination in surface water, especially in regions where extreme rainfall may increase due to climate change. Sampling at higher frequency surrounding rainfall events would provide more detailed characterization of the risks posed by floodwater at different time scales and under different antecedent conditions.}, number={9}, journal={ACS ES&T WATER}, publisher={American Chemical Society (ACS)}, author={Harris, Angela R. and Fidan, Emine N. and Nelson, Natalie G. and Emanuel, Ryan E. and Jass, Theo and Kathariou, Sophia and Niedermeyer, Jeffrey and Sharara, Mahmoud and Reyes, Francis Lajara, III and Riveros-Iregui, Diego A. and et al.}, year={2021}, month={Sep}, pages={2012–2019} } @article{parsons_niedermeyer_gould_brown_strules_parsons_bernardo mesa‐cruz_kelly_hooker_chamberlain_et al._2020, title={Listeria monocytogenes at the human–wildlife interface: black bears ( Ursus americanus ) as potential vehicles for Listeria}, volume={13}, ISBN={1751-7915}, ISSN={1751-7915 1751-7915}, url={http://dx.doi.org/10.1111/1751-7915.13509}, DOI={10.1111/1751-7915.13509}, abstractNote={Summary}, number={3}, journal={Microbial Biotechnology}, publisher={Wiley}, author={Parsons, Cameron and Niedermeyer, Jeff and Gould, Nicholas and Brown, Phillip and Strules, Jennifer and Parsons, Arielle W. and Bernardo Mesa‐Cruz, J. and Kelly, Marcella J. and Hooker, Michael J. and Chamberlain, Michael J. and et al.}, editor={Brown, PhillipEditor}, year={2020}, month={May}, pages={706–721} } @article{parsons_chen_niedermeyer_hernandez_kathariou_2019, title={Draft Genome Sequence of Multidrug-Resistant Listeria innocua Strain UAM003-1A, Isolated from a Wild Black Bear (Ursus americanus)}, volume={8}, ISSN={["2576-098X"]}, DOI={10.1128/MRA.01281-19}, abstractNote={ There is currently limited knowledge of the genome sequences of nonpathogenic Listeria species, especially strains from wildlife.

Due to their growth requirements, these Campylobacter spp. may be unable to replicate once excreted by their avian hosts, but their survival in feces and the environment is critical for transmission in the farm ecosystem. Reducing the prevalence of Campylobacter -positive flocks can have major impacts in controlling both contamination of poultry products and environmental dissemination of the pathogens. However, understanding the capacity of these pathogens to survive in transmission-relevant vehicles such as feces and farmhouse water remains poorly understood, and little information is available on species- and strain-associated differences in survival. Here, we employed model conditions to investigate the survival of C. jejuni and C. coli from naturally colonized turkey flocks, and with diverse genotypes and antimicrobial resistance profiles, in turkey feces and in farmhouse water. }, number={22}, journal={APPLIED AND ENVIRONMENTAL MICROBIOLOGY}, author={Good, Lesley and Miller, William G. and Niedermeyer, Jeffrey and Osborne, Jason and Siletzky, Robin M. and Carver, Donna and Kathariou, Sophia}, year={2019}, month={Nov} } @article{niedermeyer_ring_miller_genger_lindsey_osborne_kathariou_2018, title={Proximity to Other Commercial Turkey Farms Affects Colonization Onset, Genotypes, and Antimicrobial Resistance Profiles of Campylobacter spp. in Turkeys: Suggestive Evidence from a Paired-Farm Model}, volume={84}, ISSN={["1098-5336"]}, DOI={10.1128/AEM.01212-18}, abstractNote={ Colonization of poultry with Campylobacter at the farm level is complex, poorly understood, and critically linked to contamination of poultry products, which is known to constitute a leading risk factor for human campylobacteriosis. Here, we investigated the use of a paired-farm design under standard production conditions and in the absence of experimental inoculations to assess potential impacts of farm and host genetics on prevalence, antimicrobial resistance and genotypes of Campylobacter in commercial turkeys of two different breeds. Data suggest impacts of farm proximity to other commercial turkey farms on the onset of colonization, genotypes, and antimicrobial resistance profiles of Campylobacter colonizing the birds. Furthermore, the significant association of a specific multidrug-resistant Campylobacter jejuni strain with turkeys of one breed suggests colonization partnerships at the Campylobacter strain-turkey breed level. The study design avoids potential pitfalls associated with experimental inoculations, providing novel insights into the dynamics of turkey colonization with Campylobacter in actual farm ecosystems. }, number={18}, journal={APPLIED AND ENVIRONMENTAL MICROBIOLOGY}, author={Niedermeyer, Jeffrey A. and Ring, Lynde and Miller, William G. and Genger, Seiche and Lindsey, Christina Parr and Osborne, Jason and Kathariou, Sophia}, year={2018}, month={Sep} }
