Microbiological contamination and antimicrobial resistance in seawater samples from three beaches in Trujillo, Peru.

Abstract

Beaches worldwide are popular tourist destinations that attract both local and international tourists and the increase in population density in the summer season generates an increase in domestic and industrial waste dumped into the seas and oceans, the present work of The objective of the research is to determine the antibacterial sensitivity of bacteria isolated in seawater; For which the three most popular beaches of La Libertad were sampled during October and November of 2023. The results obtained showed that the beaches of Salaverry have good microbiological quality, while the microbiological quality of the beaches of Las Delicias and Huanchaco is poor; E coli being the bacteria that is isolated most frequently and presents resistance to Ampicillin (AMP) and Ciprofloxaxin (CIP): this research concludes that due to the dumping of wastewater in coastal areas, microbiological contamination of the beaches is produced, which is a danger. latent for bathers who come during the summer.
