LIMA, Carlos Alberto de A.; PASTORE, Gláucia Maria  y  LIMA, Eliza Dorotea Pozzobon de A.. Study of the antibacterial activity of anacardic acids from the cashew Anacardium occidentale nut shell oil of the clone of cashew-midget-precocious CCP-76 and and CCP-09 in five stages of maturation on oral microorganisms. Ciênc. Tecnol. Aliment. [online]. 2000, vol.20, n.3, pp.358-362. ISSN 0101-2061.

The antimicrobial activity of the anacardic acids of the cashew nut shell oil Anacardium occidentale (Anacardiaceae) was studied on the oral microorganisms Streptococcus mutans ATCC 25175, Staphylococcus aureus ATCC 12598, Candida albicans ATCC 10231 and Candida utilis. The anacardic acids obtained from the ethyl extract of the cashew nut shell oil presented activity antibacterial against the mentioned microorganisms, but the most inhibitory activity occurred with the Gram positive bacteria Streptococcus mutans, which is known to be one of the main cause of tooth decay. The tooth decay is one of the most frequent infectious diseases in the countries in development. The elements that influence in the tooth decay include the nutritional state, the ingestion of sugar and the presence of the microflora cariogênica.

Palabras clave : Anacardic acids; cashew nut shell oil; Anacardium occidentale; activity antimicrobial.
