RESUMO No Nordeste brasileiro, cuja vegetação predominante é Caatinga, muitas plantas nativas ou exóticas são potencialmente ricas em propriedades curativas, porém pouco exploradas ainda pela ciência. O trabalho foi realizado durante agosto de 2011 a junho de 2012, onde foram coletadas amostras bacterianas dos tetos dos animais através de swabs estéreis. Isolados e devidamente identificados, os microrganismos foram sujeitos a antibiogramas com os meios alternativos, controles positivos e negativo através da técnica de difusão em Ágar de poço. O objetivo do trabalho foi avaliar a ação dos extratos de Favela (Cnidoscolus phyllacanthus), Catingueira (Caesalpinia pyramidalis) e Nim (Azadiracta indica) sobre bactérias isoladas de tetos de cabras no assentamento de Cordão de Sombra no Município de Mossoró-RN.   ABSTRACT In Northeast Brazil, whose predominant vegetation is Caatinga, many native or exotic plants are potentially rich in healing properties, but little explored yet by science. The work was conducted during August 2011 to June 2012, where bacterial samples were collected from the teats of animals through sterile swabs. Once isolated and properly identified, the microorganisms were subjected to antibiograms with alternative means, positive and negative controls through the well agar diffusion technique. The objective of the work was to evaluate the action of extracts of Favela (Cnidoscolus phyllacanthus), Catingueira (Caesalpinia pyramidalis) and Neem (Azadiracta indica) on bacteria isolated from teats of goats in the settlement Cordão de Sombra in the Municipality of Mossoró-RN.

A comparative study of an old and fresh ATCC strain of Staphylococcus aureus was carried out to determine the mechanism of antibiotic resistance of the old one, which had been preserved in lyophilized condition. Five different antibiotics having five different modes of action were used. They included amoxicillin, azithromycin, neomycin, ciprofloxacin and polymixin B. Agar diffusion technique was followed to determine the antibiotic sensitivity. It was observed that the old strain showed the highest resistance against amoxicillin, whereas no remarkable changes in the sensitivity pattern were observed against polymixin B and neomycin. In case of azithromycin and ciprofloxacin, the old strain showed resistance up to some extent. From these results it was clearly evident that in the controlled preserved conditions, cell wall-mediated resistance was predominating, while the cell membrane- and 30S ribosome-mediated resistance were the least likely ones. The nucleic acid synthesis inhibitors and the 50S ribosomal protein synthesis inhibitor lied in between these two extremes showing variations up to some extent in the sensitivity pattern between the old and fresh ATCC strain of S. aureus.
