“…The OR exhibited significant antimicrobial activity (minimum inhibitory concentrations [MIC] ≤100 μg/mL) against samples of Staphylococcus coagulase-positive, Staphylococcus coagulase-negative, and Streptococcus but were inactive and weak to inactive, respectively, against E. coli . This demonstrates that this raw plant material is promising for the development of phytotherapeutic drugs against bovine mastitis [ 35 ].…”

Efficacy of novel antiseptic product containing essential oil of Lippia origanoides to reduce intramammary infections in cows

et al. 2020

Background and Aim: The use of antimicrobials in the control of mastitis is of concern in public health due to their inefficiency in targeting microorganisms. Studies with medicinal plants have risen as an alternative to the use of conventional products. The objective of this study was to evaluate the efficacy of an experimental disinfectant based on the essential oil (EO) from Lippia origanoides in preventing the development of new intramammary infections (IMI) in Holstein cows. Materials and Methods: The conventional protocol of pre- and post-milking was used and the control (Conventional treatment [CNV]) and experimental (Experimental treatment [PEX]) products containing EO at 120 μL/mL were applied by immersion. Individual milk samples were analyzed using sheep blood agar methodologies and biochemical tests. The efficiency of the treatment was defined by the presence or absence of Staphylococcus aureus, coagulase-negative Staphylococcus, and Streptococcus spp. Results: There were no clinical and subclinical mastitis cases, no lesions in the mucosal of teats, nor dirt score between groups in this study. Both treatments did not influence the occurrence of IMI. Conclusion: The results revealed that PEX acts efficiently against microorganisms compared to the disinfection by the conventional product demonstrating the efficacy of the alternative product on the prevention of new IMIs in dairy cows.

“…Tal fato requer atenção, uma vez que as bactérias vêm adquirindo cada vez mais resistência às drogas introduzidas na medicina humana e veterinária de modo usual, o que exige medidas urgentes no combate ao surgimento de novas cepas bacterianas multirresistentes, inclusive aos medicamentos antimicrobianos recentemente comercializados, levando à consequências importantes, com efeitos diretos na problemática das infecções hospitalares (6) . Além disso, torna-se necessário maiores investimentos das indústrias farmacêuticas em pesquisas sobre o desenvolvimento de drogas utilizando princípios ativos naturais, em particular metabólitos de plantas medicinais, recentemente, demonstrado na literatura uma boa atividade frente a cepas de Staphylococcus isolados de leite de vacas com mastitite (31) .…”

SUSCEPTIBILIDADE DE Staphylococcus aureus ISOLADOS DE LEITE CRU A ANTIBIÓTICOS COMERCIAIS

et al. 2018

Resumo O leite possui extremo valor na dieta humana e constitui um excelente substrato para o crescimento de grande diversidade de microrganismos, dentre eles o Staphylococcus aureus, frequentemente encontrado no leite cru, e que se destaca como um dos microrganismos mais prevalentes em casos de mastite bovina no mundo. Objetivou-se avaliar a sensibilidade de cepas de S. aureus isoladas de leite cru à antimicrobianos comerciais. Para isso, selecionaram-se antibióticos com base em pesquisas junto a estabelecimentos comerciais de medicamentos veterinários no município de Zé Doca, Estado do Maranhão, Brasil. Esses antibióticos foram identificados por associação à base de penicilina, estreptomicina, isoniazida e prednisolona (BPC), oxitetraciclina base (TOR), associação à base de penicilina e estreptomicina (MPP) e cloridrato de tetraciclina (TCA). Posteriormente, realizou-se contagem de Staphylococcus spp., com isolamento e identificação bioquímica das cepas de S. aureus as quais, em seguida, foram submetidas à antibiogramas com identificação de ce,pas produtoras de beta-lactamase. Os resultados demonstraram contaminação em todas as amostras por Staphylococcus spp., com contagens de 1,9 x 103 a 5,24 x 106 UFC/mL. Dentre os antibióticos testados, o TOR apresentou maior eficiência na eliminação ou redução de todas as cepas de S. aureus. Verificou-se que 50% das cepas de S. aureus isoladas produziram enzima beta-lactamase. Torna-se necessário a criação de medidas de combate ao surgimento de novas cepas bacterianas e atuação das autoridades públicas, fiscalizando a comercialização de medicamentos veterinários.

“…The choice of Copaifera spp. (Copaíba) is due to its antimicrobial action in previous studies that used plants of the same genus (Faria et al, 2017;Vieira et al, 2018 Bacterial strains were plated on Sodium Thioglycolate (BBL) broth supplemented with Hemina + Vitamin K (5μg / ml) (LABORCLIN, Brazil). The plates containing bacterial strains were incubated overnight at 37°C and subsequently stored at 4°C.…”

Endodontic infections are polymicrobial and predominantly caused by anaerobic bacteria and some facultative bacteria. The list of microorganisms involved in endodontic infections keeps expanding and has the potential to become increasingly more accurate during the next few years. Copaiba oil is an important Amazonian herbal medicine commercialized worldwide. In this study, we evaluated the antimicrobial activity and minimum inhibitory concentration (MIC) of copaiba oil and substances used in the treatment of endodontic infections against anaerobic microorganisms such as Prevotella melaninogenica; Prevotella intermedia; and Clostridium acetobutylicum. The MIC was determined by thioglycollate broth dilution. The data were statistically analyzed by Tukey's parametric and nonparametric methods of Cochran and Kruskal-Wallis test with a confidence level of 99%. The analysis of the antimicrobial activity showed that the samples of Copaíba oil, Sodium Hypochlorite, Otosporin, Tricresol formalin, Chlorhexidine and PMCC showed high antimicrobial activity (p <0.01). However, different copaiba samples presented different activities. The results reveal Copaíba l sample was the most effective against anaerobic bacteria.
