Vibrio vulnificus and V. parahaemolyticus in the estuarine-marine environment are of human health significance may be increasing pathogenicity abundance. illness originating from dermal contact with laden waters or through ingestion seafood such can cause deleterious effects, particularly if strains involved resistant to clinically important antibiotics. The purpose this study was evaluate antimicrobial susceptibility among these pathogens. Surface-water samples were collected three sites...
The incidence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections is increasing in the United States, and it possible that municipal wastewater could be a reservoir this microorganism. To date, no U.S. studies have evaluated occurrence MRSA wastewater.We examined methicillin-susceptible S. (MSSA) at treatment plants.We collected samples from two Mid-Atlantic Midwest plants between October 2009 2010. Samples were analyzed for MSSA using membrane filtration....
Reclaimed water has emerged as a potential irrigation solution to freshwater shortages. However, limited data exist on the persistence of antibiotics in reclaimed used for irrigation. Therefore, we examined fate nine commonly-used (ampicillin, azithromycin, ciprofloxacin, linezolid, oxacillin, oxolinic acid, penicillin G, pipemidic and tetracycline) differentially treated wastewater from two U.S. regions. We collected 72 samples Mid-Atlantic Midwest treatment plants, well one spray site....
Self-medication with antibiotics is an important factor contributing to the development of bacterial antibiotic resistance. The purpose this study was evaluate prevalence self-medication for treatment menstrual symptoms among university women in Southwest Nigeria. A cross-sectional survey administered female undergraduate and graduate students (n = 706) at four universities Nigeria 2008. were selected by convenience samples within each randomly cluster samples. self-administered included...
The COVID-19 pandemic impacted mental health. Growing research has identified the health benefits of nature contact, including gardening. We used a cross-sectional survey to investigate association between gardening and other outdoor activities with anxiety among U.S. adults. RANG (Reducing Anxiety Nature Gardening) was distributed online from June–September 2020 through social media (Twitter Facebook) national Master Gardeners listserv. Survey questions captured demographics, experiences,...
Water reuse, the beneficial use of highly treated municipal wastewater (reclaimed water), is expanding throughout United States (U.S.); however, there are currently no federal reclaimed water regulations, only guidelines. As a result, state policies on vary widely, emphasizing need for comprehensive understanding to facilitate coordinated national planning. Our systematic literature review, utilizing an online legal research database, presents updated overview U.S. from 2004 2023. A novel...
As reclaimed water use expands, it is important to evaluate potential occupational health risks from exposure this alternative source. We compared odds of colonization with methicillin-resistant Staphylococcus aureus (MRSA), methicillin-susceptible S. (MSSA), vancomycin-resistant enterococci (VRE), and vancomycin-susceptible (VSE) between spray irrigation workers using office worker controls. Nasal dermal swabs 19 24 controls were collected analyzed for MRSA, MSSA, VRE, VSE. Isolates...
Campylobacter is a leading cause of foodborne illness in the United States. infections have been associated with individual risk factors, such as consumption poultry and raw milk. Recently, Maryland-based study identified community socioeconomic environmental factors that are also campylobacteriosis rates. However, no previous studies evaluated association between rates across multiple U.S. states.We obtained case data (2004-2010; n = 40,768) from Foodborne Diseases Active Surveillance...
In the last several decades, Maryland’s Eastern Shore has seen significant declines in groundwater levels. While this area is not currently experiencing drought conditions or water scarcity, research represents a proactive approach.
Although many U.S. homes rely on private wells, few studies have investigated the quality of these water sources. This cross-sectional study evaluated well in Maryland, and explored possible environmental sources that could impact quality. Well samples (n = 118) were collected four Maryland counties analyzed for microbiological chemical contaminants. Data from Census Agriculture used to evaluate associations between presence animal feeding operations at zip code level using logistic...
Enteric bacterial pathogen levels can influence the suitability of irrigation water sources for fruits and vegetables. We hypothesize that stable spatial patterns Salmonella enterica Listeria monocytogenes may exist across surface in Mid-Atlantic U.S. Water samples were collected at four streams two pond sites mid-Atlantic over 2 years, biweekly during fruit vegetable growing seasons, once a month nongrowing seasons. Two stream one site had significantly different mean concentrations Stable...
ABSTRACT Alternative irrigation waters (rivers, ponds, and reclaimed water) can harbor bacterial foodborne pathogens like Salmonella enterica Listeria monocytogenes , potentially contaminating fruit vegetable commodities. Detecting using qPCR-based methods may accelerate testing procedures compared to culture-based methods. This study detection of S. L. by qPCR (real-time PCR) culture in determine the influence water type (river, pond, water), season (winter, spring, summer, fall), or volume...
We evaluated the combined impact of community-level environmental and socioeconomic factors on risk campylobacteriosis.We obtained Campylobacter case data (2002-2010; n = 3694) from Maryland Foodborne Diseases Active Surveillance Network. 2000 US Census 2007 Agriculture. linked by zip code. derived incidence rate ratios Poisson regressions. mapped a subset code-level characteristics.In codes that were 100% rural, (IRRs) campylobacteriosis 6 times (IRR 6.18; 95% confidence interval [CI] 3.19,...
