Public Policies and One Health in Brazil: The Challenge of the Disarticulation.

Working the One health strategy in developing countries is a challenge, due to structural weaknesses or deprivation of financial, human, and material resources. Brazil has policies and programs that would allow continuous and systematic monitoring of human, animal, and environmental health, recommending strategies for control and prevention. For animals, there are components of the Epidemiological Surveillance of zoonosis and Animal Health Programs.

Increased production of biofilms by Escherichia coli in the presence of enrofloxacin.

The literature has demonstrated that subinhibitory concentrations of some antimicrobials are able to induce biofilm formation by certain bacterial species. Biofilms present in the mammary glands of cattle contribute to antimicrobial resistance, resulting in the appearance of persistent mastitis and consequent great losses to the dairy sector worldwide. The present study aimed to investigate the induction of biofilm formation by enrofloxacin in Escherichia coli isolates obtained from bovine mastitis.
