“…In our study, the isolation rate of type F C. perfringens from asari clams heated at 80 °C for 10 min was 9%, which is the same with the results of previous studies showing isolation rates of 8% and 12%, respectively, in scallops and oysters [ 16 , 19 ]. Zhang et al [ 53 ] described that C. perfringens in beach sand showed a slower decay than that in seawater, supporting our results that showed a high isolation rate of asari clams in beach sand, while those of benthic crabs in a sewage-polluted estuary and fish were 1% and 1.4%, respectively [ 54 , 55 ]. These results suggested that the isolation rate of type F C. perfringens spores from bivalves is higher than those from other foods, primarily meat products.…”

Clostridium perfringens is an important pathogen that is responsible for gastroenteritis; the causative agent for the symptoms is C. perfringens enterotoxin (CPE), which is mainly produced by type F C. perfringens. Since shellfishes may gather C. perfringens in the water environment, this study estimated the potential circulation of type F C. perfringens among humans, sewage, and Ruditapes philippinarum (asari clams) as a result of sewage pollution. A comparison of the characteristics among the isolates from 86 sewage influents, 36 effluents, 76 asari clams, and 37 humans was conducted. Serotyping, cpe genotyping, and toxin genotyping showed that C. perfringens with a plasmid IS1151 sequence downstream of cpe was predominant among sewage influents, effluents, humans, and asari clams. Multilocus sequence typing suggested that some isolates from a human, sewage influents, effluents, and asari clams were linked to each other. These results demonstrated that asari clams are the necessary infection sources of C. perfringens responsible for carriers and foodborne diseases, and that these pathogens from humans infected by asari clams can pollute the water environment. It is useful to assess bacteria such as C. perfringens isolates from sewage to estimate the trend of those from the community.

“…typhimurium, Salmonella enterica var. gallinarum and Escherichia coli (La Sala et al 2014), whereas Olrog's Gull prey crabs N. granulata and C. angulatus from some of the FAs identi ed here carried Clostridium perfringens type A in their gastrointestinal tracts (La Sala et al 2015). With this background, our results raise yet another concern about the health risks for Olrog's gulls in the study area, and mostly in FAs near industry e uents and sewage outfalls.…”

Seabird populations worldwide are facing signi cant declines due to various threats, making them valuable bioindicators of marine ecosystem changes. Understanding their foraging behavior and identifying crucial foraging areas is essential for their conservation. In this study, we focused on Olrog's Gull (Larus atlanticus), a near-threatened species endemic to the Atlantic coast of Argentina, Uruguay, and southern Brazil. Our objectives were to assess the distribution of foraging areas (FAs) and home ranges, describe temporal ight patterns, and evaluate FA overlap with protected areas in the Bahía Blanca Estuary (BBE), Argentina. We used GPS tracking with dynamic Brownian bridge movement models (dBBMM) to analyze Olrog's Gull behavior during their breeding season. Our results revealed well-de ned FAs, with 72% of them being located outside protected areas, raising concerns about potential threats to the species. We observed sex-related differences, with females covering longer distances during foraging ights. Additionally, several FAs were situated near industrial sites, posing health risks due to potential pollution. This study contributes novel insights into Olrog's Gull foraging ecology, particularly in the most critical breeding area for the species. We developed a dynamic web application for easy access to conservation-relevant information. Our ndings emphasize the need for enhanced protection of key FAs, especially those outside existing protected areas, to safeguard the species and its ecosystem. These results underscore the importance of informed policy decisions to preserve Olrog's Gull populations and their habitats in the face of growing human-related threats.

“…Today, bacteria of the Clostridium genus are a large and widespread group among anaerobes. They are found in various climatic zones, in a wide variety of soils, in water and bottom sediments of lakes, rivers, seas and oceans (La Sala et al, 2015;Abia et al, 2015;Trubnik et al, 2017;Fedorov et al, 2018). The formation of spores provides them with the possibility of long-term conservation in the habitat until the onset of favorable conditions for vegetation (Bukharin and Litvin, 1997;El-Shorbagy et al, 2012).…”

The paper presents studies on the infection with clostridia of fish with skin lesions and ulcers on the surface of the body. The objects of study were syrman goby from the eastern part of the Taganrog Bay of the Sea of Azov, turbot from the shelf zone of the northeastern Black Sea and carps reared under aquaculture conditions. Using an Autoflex speed III Bruker Daltonics (Germany) mass spectrometer, by the MALDI-TOF mass spectrometry was showed that sulfite-reducing clostridia (Clostridium perfringens, C. sporogenes) have been shown to infect the organs and tissues of syrman goby with vibriosis and turbot with ulcerative skin lesions of unknown etiology. Species such as Clostridium difficile, Clostridium novyi are of clinical importance and were found in the parenchymal organs of carp suffering from chronic aeromonas infection on pond fish farms in the southern Russia. These bacteria are its cosmopolitan distribution ability them to generate heat-resistant spores and cause food poisoning, which makes control and prevention measures needed in the food chain.
