Multi-resistant microorganisms such as Escherichia coli
, Staphylococcus aureus
, Pseudomonas aeruginosa
, Candida tropicalis
e Candida krusei
are the main causes of microbial infections. Padina sanctae-crucis
is a seaweed often used to check the contamination of ecosystems by materials such as heavy metals, but studies of the antimicrobial activity of the same seaweed were not found.
The tests for the minimum inhibitory concentration and modulation of microbial resistance, with the use of ethanolic and methanolic extracts of Padina Sanctae-cruces
combined with drugs of the class of aminoglycosides and antifungal were used to evaluate the activity against the cited microorganisms.
Was observed a modulation of antibiotic activity between the natural products and the E. col
and S. aureus strains
, indicating a synergism and antagonism respectively.
The results showed a moderate modulatory effect against some microorganisms studied.
