18. Adenovirus molecular detection and seasonal monitoring in bodies of water in the municipality of Goiânia, Goiás-Brazil: correlation with physical-chemical and bacteriological parameters and meta-analysis to evaluate methodologies / Detecção molecular e monitoramento sazonal de adenovírus em águas fluviais no município de Goiânia, Goiás-Brasil: correlação com parâmetros físico-químicos, bacteriológicos e Metanálise avaliativa de metodologias
Although water is of vital importance for living beings, due to antropic action it becomes a way of dissemination of several microorganisms, which reach aquatic environments through the faeces of man and other animals and can cause several illnesses, especially for immunocompromised individuals. During routine environmental monitoring, coliform bacteria are
