Abstract(s)
Os espaços verdes nas grandes cidades têm ganho uma importância crescente
para a qualidade de vida e saúde da população. Os lagos e fontes
ornamentais presentes nestes espaços são muito atrativos, mas podem
esconder alguns perigos.
Neste estudo foi avaliada mensalmente durante um ano a flora bacteriana
(planctónica e organizada em biofilmes) presente num lago ornamental de
um parque urbano situado em Lisboa (Portugal).
Foram identificadas bactérias pertencentes a 14 Géneros diferentes, mas
apenas as Aeromonas spp. foram identificadas em todas as colheitas na
água e/ou biofilmes sendo consideradas residentes. A suscetibilidade aos
antibióticos e à cloragem foram avaliadas para esta população residente.
Os resultados obtidos permitiram identificar um grupo de bactérias
residentes que não são alvo de pesquisa dedicada de acordo com a
legislação em vigor em Portugal. O nível de eficácia da cloragem na
eliminação de biofilmes destes microrganismos sugere a necessidade de
monitorização e/ou uso de métodos de desinf
Urban parks and other green spaces in large cities have gained increasing importance for the quality of life and health of inhabitants. The lakes and ornamental fountains present in these spaces are very attractive, but can hide some dangers. In this study, the bacterial flora (planktonic and organized in biofilms) present in an ornamental lake in an urban park located in Lisbon (Por tugal) was evaluated monthly for a year. Bacteria from 14 different Genus were identified, but only Aeromonas spp. were identified in all water collections and/or biofilms being considered as residents. Susceptibility to antibiotics and chlorination were assessed for this resident population. The obtained results allowed the identification of a resident bacterial group that are not target of dedicated research in accordance with the legislation in force in Portugal. The level of effectiveness of chlorination in eradicating biofilms of these microorganisms suggests the need for monitoring and/or use of more effective disinfection
