Description
Marcela Calciolari Branquinho and co-authors put two plant oils, from tea tree and copaiba, against bacteria that cause udder infection in cows and resist many drugs. The panel mixed standard laboratory strains with bacteria taken from real mastitis cases, including a methicillin-resistant Staphylococcus aureus. Strength needed to stop or kill each germ was measured by standard dilution methods.
Tea tree oil worked across more germs, halting Escherichia coli outright and slowing two streptococcus species from clinical cases, though it did not kill the streptococci at the doses tried. Copaiba oil was narrower, slowing only the same two streptococci and killing none. Neither oil touched Klebsiella or the resistant staphylococcus in range. The authors rate tea tree oil as the stronger candidate for further work as a helper or alternative treatment.
