TITLE:

Silver nanoparticles in the fight against bovine mastitis caused by Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli.

SUMMARY:

Mastitis is the disease with the greatest impact on milk production, an infection that affects the mammary glands and can be caused by fungi, algae and bacteria. Bacterial infection is responsible for 90% of cases, with S. aureus, K. pneumoniae and E. coli being the most prevalent. The aim of the present study was to test in vitro nanoparticulate silver against the agents S. aureus, K. pneumoniae and E. coli for the treatment of bovine mastitis. 9 concentrations were tested for the susceptibility test, and for the quantification tests of planktonic cells, viable cells in biofilm, biomass and toxicity by the chorioallantoic membrane, 4 concentrations were tested. The silver nanoparticles proved effective in combating and reducing the 3 agents tested. From the results obtained in this work, the silver nanoparticle proved to be a promising alternative, especially for S. aureus and E. coli.
