Understanding the risks of co-exposures in a changing world: A case study of dual monitoring of the biotoxin domoic acid and Vibrio spp. in Pacific oyster
<div> <p><span>Assessing the co-occurrence of multiple health risk factors in coastal ecosystems is challenging due to the complexity of multi-factor interactions and limited availability simultaneously collected data. Understanding co-occurrence is particularly important for risk factors that may be associated with or occur in similar environmental conditions. In marine ecosystems, the co-occurrence of harmful algal bloom toxins and bacterial pathogens within the genus <em>Vibrio </em>may impact both ecosystem and human health. This study examined the co-occurrence of <em>Vibrio</em> spp. and domoic acid (DA) produced by the harmful algae <em>Pseudonitzschia</em> by 1) analyzing existing California Department of Public Health monitoring data for <em>V. parahaemolyticus</em> and DA in oysters; 2) and conducting a one-year seasonal monitoring of these risk factors across two Southern California embayments. Existing public health monitoring efforts in the state were robust for individual risk factors; however, it was difficult to evaluate the co-occurrence of these risk factors in oysters due to low number of co-monitoring instances between 2015 and 2020. Seasonal co-monitoring of that DA and <em>Vibrio</em> spp. (<em>V. vulnificus</em> or <em>V. parahaemolyticus</em>) at two embayments revealed the co-occurrence of these health risk factors in 35% of sampled oysters in most seasons. Interestingly, both the overall detection frequency and co-occurrence of these risk factors was considerably less frequent in water samples. These findings may in part suggest the slow depuration of <em>Vibrio </em>spp. and DA in oysters as residual levels may be retained. This study expanded our understanding of the simultaneous presence of DA and <em>Vibrio</em> spp. in bivalves and demonstrate the feasibility of co-monitoring different risk factors from the same sample. Individual programs monitoring for different risk factors from the same sample matrix may consider combining efforts to reduce cost, streamline the process, and better understand the prevalence of co-occurring health risk factors.</span></p> </div>

Variable freshwater influences on the abundance of vibrio vulnificus in a tropical urban estuary
<p>Our data illustrate that, in the absence of strong seasonal variation in water temperature in the tropics, variation in salinity driven by rainfall becomes a primary controlling variable on V. vulnificus abundance. There is thus a tendency for a rainfall-driven seasonal cycle in V. vulnificus abundance which is inverted from the temperature-driven seasonal cycle at higher latitudes.</p>
