“…Resistance of bacteria occurring in marine ecosystems to different antibiotics was recorded in seawater, sediments and beach sand (Schwartz et al 2003, Mudryk 2005, Mudryk et al 2010, Oliveira et al 2010, Manivasagan et al 2011. The rapid increase in the number of resistant and multiresistant aquatic bacteria is partly due to their ability to transfer antibiotic resistance agents (plasmids, transposons and integrons) among bacterial populations by cell to cell contact (Oliveira et al 2010).…”

“…Bacteria occurring in wet sand (seawater, the shoreline zone and the middle part of the beach) were more antibiotic-resistant than bacteria isolated from dry sand (dune). Also Mudryk (2005), Mudryk et al (2010) and Oliveira et al (2010) in their research documented a difference in the distribution of bacteria with varied antibiotic resistance, which occurred in wet and dry sand of coastal beaches.…”

“…The study carried out by Mudryk (2005) at the coastal sandy beach in Sopot (the southern Baltic Sea) showed that bacteria isolated from the surface sand layers were more resistant to nearly all tested antibiotics compared to bacteria from the subsurface layers. In the present study, no difference was found in antibiotic resistance of Staphylococcus-like organisms inhabiting the surface and subsurface sand layers, which corresponds to the results presented by Mudryk et al (2010) from a non-recreational beach in Czołpino (southern Baltic Sea).…”

Antibiotic resistance of Staphylococcus-like organisms (STLO) isolated from a recreational sea beach located on the southern coast of the Baltic Sea was studied. The results of the present study showed that STLO inhabiting sand and seawater of the beach strongly differed in the resistance level to tested antibiotics. These microorganisms were most resistant to ampicillin, penicillin, oxytetracycline and susceptible to gentamicin, neomycin and streptomycin. Moreover, the level of antibiotic resistance among bacteria isolated from different parts of the beach also differed. Bacteria inhabiting the seawater, shoreline and the middle part of the beach were more antibioticresistant than bacteria isolated from the dune. The majority of bacteria inhabiting the seawater and sand were resistant to 3-8 antibiotics out of 12 tested in this study. Generally, there was no difference in antibiotic resistance between Staphylococcus-like

“…항생제에 대한 의존도는 지난 수 십 년간 의학, 수의학, 농 업, 수산업 등의 분야에서 꾸준히 증가되어 왔으나, 그 결과 얼마 나 많은 양의 항생제가 자연계로 유입되었는지에 대해서는 파악 된 바가 없다. 항생제 사용 범위는 곧 바로 세균들에 가해지는 선 택압력의 지표가 되며 (Schwartz et al, 2003), 그로 인해 많은 세 균들이 항생제를 무력하게 하는 다양한 효과적인 기작들을 획득 하게 되었다 (Mudryk, 2005). 특히 항생제가 많이 사용되는 병원 같은 곳에서 다제 내성균들이 많이 출현하게 되었고, 양식장에 서 질병 예방이나 치료를 위해 사료에 항생제를 첨가하게 되면 서 수계에서도 많은 항생제 내성균들이 발견되고 있다 (Schwartz et al, 2003;Kumar et al, 2009).…”

Vibrio parahaemolyticus is one of the major agents responsible for food poisoning during summer in Korea, which is transmitted via seawater or seafoods. Recently, distribution of the bacteria in the marine environment has been increased due to global warming. Great concern also has been raised regarding public hygiene as well as marine culture by the emergence of pathogens with antibiotic resistance. Therefore, distribution of V. parahaemolyticus and antibiotic resistance of the isolates were monitored in 7 coastal areas of Kyonggi Province and Incheon by sampling seawater, fishes and clams monthly. V. parahaemolyticus was detected from 47.7% of 966 samples (seawater 61.9%, seafoods 41.8%) analyzed using CHROMagar TM and TCBS agar plates as well as multiplex PCR. Among 13 antibiotics tested, resistance to vancomycin and ampicillin was observed in 97.3% and 87.3% of the isolates, respectively, and the ratios of them resistant to cephalothin (48.8%) and rifampin (46.1%) were also high. The isolates were most highly sensitive to chloramphenicol (91.7%) and trimethoprim-sulfamethoxazole (91.8%). The ratio of sensitivity for other antibiotics was also high in the descending order of gentamycin (82.3%), tobramycin (74.8%), nalidixic acid (71.6%), tetracyclin (69.4%), cefotaxime (63.0%). About 69% of the isolates showed multiple drug resistance toward 3 antibiotics including vancomycin and ampicillin. Two of them exhibited resistance for 11 antibiotics used in this study. Plasmid profile analysis of the isolates with antibiotic resistance revealed that 55.1% of them retained plasmids of 24 different types. However, no clear inter-relationship between the resistance and the plasmid profile has been observed.

“…Além de serem fontes potenciais de contaminação de humanos por patógenos, as águas marinhas que recebem esgotos domésticos podem contribuir também para o estabelecimento de rotas de disseminação de microrganismos portadores de genes de resistência a antimicrobianos 70,71 . Recentemente, muitos estudos têm mostrado a existência de bactérias resistentes a antibióticos em águas doces, estuários, águas marinhas costeiras e em esgotos 70,72,73,74,75,76,77 . Assim, a poluição de águas marinhas pelo despejo de efluentes provenientes de ambientes fortemente seletivos para cepas bacterianas resistentes, tais como hospitais, indústrias, entre outras, dependendo de sua sobrevivência e/ou declínio no ambiente, pode levar a um aumento da distribuição e da frequência de genes bacterianos de resistência 78 .…”

ResumoOs sistemas de disposição oceânica de esgotos domésticos, ou emissários submarinos, têm sido historicamente utilizados em todo o mundo como solução para destinação final de efluentes urbanos, principalmente devido aos aspectos econômi-cos. Porém, o descarte no oceano, seja em águas rasas ou mais profundas, pode induzir uma série de impactos ambientais negativos, dos quais se destacam a eutrofização, a floração de algas tóxicas, a introdução de microrganismos patogênicos e a contaminação por substâncias químicas capazes de produzir efeitos tóxicos sobre a biota e bioacumulação. Desse modo, o lançamento de esgoto não tratado no mar não constitui uma prática ambientalmente adequada, sendo necessário o tratamento dos efluentes de forma a remover nutrientes, contaminantes e organismos patogênicos e evitar a degradação ambiental. Palavras-chave:Esgotos. Emissário Submarino. Poluição. Saúde Pública. AbstractOceanic disposal systems of domestic sewage, or submarine sewage outfalls, have been historically used around the world as a solution for urban effluents, in special due to economic aspects. However, release into the ocean, in shallow or deep waters, may induce a set of negative environmental impacts, as eutrophication, toxic algal blooms, pathogenic microorganisms introduction and contamination by chemical substances which are capable of causing toxic effects to the biota and bioaccumulation. Thus, the release of untreated sewage into the sea does not constitute an adequate environmental practice; then, urban effluents should be treated in order to remove nutrients, contaminants and pathogenic organisms and avoid environmental degradation.
