Green tea () extract inhibits biofilm formation in acyl homoserine lactone-producing, antibiotic-resistant isolated from Pasig River, Philippines.

The drastic development of urban districts around the world has caused changes in the environment, specifically on metropolitan waterways such as the Pasig River in the Philippines. These significant changes resulted in diversity of microorganisms and their mechanisms employed such as antibiotic resistance and their communication system or quorum sensing (QS). In this study, four bacterial isolates from Pasig River, identified as , sp.
