“…Animal trials have also demonstrated the promising effects of EOs against the colonisation and proliferation of Clostridium perfringens (Mitsch et al, 2004;Di Pasqua et al, 2007). The mechanism by which the essential oils exert their antimicrobial activity is poorly understood but the main target appears to be the cell membrane of bacterial cells (Burt, 2004;Di Pasqua et al, 2007).…”

ABSTRACT:The use of antimicrobial growth promoters has been banned in the EU. This has created an interest in alternative strategies to prevent an imbalance in the intestinal microbiota and the potential development of intestinal disorders in livestock. Essential oils (EOs) have been known to exhibit antimicrobial activity against specific microbial species and could therefore be considered one such alternative in controlling the intestinal microbial population. Under anaerobic conditions, the tested Clostridium perfringens strains were found to be sensitive (P < 0.05) to carvacrol, cinnamaldehyde, citral, limonene, thymol, particularly at the higher concentration tested (500 mg/l) and to oregano oil, rosemary oil and thyme oil. Streptococcus epidermis was sensitive (P < 0.05) to most EO's tested, also mainly at the higher concentration. The tested Salmonella serovars were found to be sensitive (P < 0.05) only to high (500 mg/l) concentrations of the tested EOs. Escherichia coli was sensitive (P < 0.05) to most of the tested EOs, also at lower concentrations (5 and 50 mg/l). Bifidobacterium longum, Bifidobacterium breve and Lactobacillus reuteri were less sensitive (P < 0.05) to most of the tested EOs, while Bifidobacterium animalis ssp. lactis and L. fermentum were relatively sensitive also at lower concentrations (5 and 50 mg/l), although growth reduction by EOs of these bacterial species was less then with the antimicrobial growth promoter avilamycin. With the exception of Salmonella and E. coli, all tested microbes were sensitive to avilamycin. Selected EOs seem to have the advantage of inhibiting the growth of potential pathogens while only moderately influencing beneficial members of the intestinal microbiota. This difference in sensitivity may strengthen the microbiota and contribute to improved animal health.

“…Segundo Mitsch et al (2004), a mistura dos princípios ativos eugenol, timol e carvacrol, constituintes do óleo essencial de orégano, tem efeito na estimulação das enzimas digestivas, estabilização da microbiota intestinal e inativação de toxinas de algumas bactérias. Dessa maneira, pode-se justificar a semelhança entre o desempenho das aves submetidas aos tratamentos T1 e T3.…”

ResumoO presente trabalho teve como objetivo avaliar dietas com óleo essencial de orégano, associado ou não com salinomicina, como alternativa à bacitracina de zinco sobre o desempenho zootécnico de frangos de corte. Foram utilizados 600 pintos de um dia de idade, machos, da linhagem Cobb® 500, criados até 42 dias de idade em boxes com cama de casca de arroz providos de comedouros tubulares e bebedouros nipple. O delineamento foi inteiramente casualizado, com seis dietas e 10 repetições de 10 aves cada. As dietas experimentais à base de milho e farelo de soja foram: controle positivo -antibiótico (bacitracina de zinco) + 0,05% de anticoccidiano (salinomicina), controle negativo -dieta basal (DB) sem aditivos, DB + 0,05% de salinomicina e 0,03% de óleo essencial de orégano (Orego-Stim®), DB + 0,03% de óleo essencial de orégano, DB + 0,05% de salinomicina e 0,05% de óleo essencial de orégano, DB + 0,05% de óleo essencial de orégano. Não foi encontrado efeito da utilização do óleo de orégano até 21 dias no desempenho das aves. Nos demais períodos, aos 35 e 42 dias, o desempenho das aves tratadas com 0,03% de óleo essencial de orégano + salinomicina apresentou resultados semelhantes ao controle positivo, levando à conclusão de que a dose de 0,03% de óleo essencial de orégano + salinomicina pode substituir a bacitracina de zinco + salinomicina em dietas para frangos de corte.

AbstractThe inclusion of oregano essential oil, alone or associated with salinomycin, was evaluated as an alternative to zinc bacitracin on the performance of broiler chickens. This study used 600 male Cobb 500® day-old chicks, raised 42 days in boxes with rice hulls, provided with tubular feeders and nipple drinkers. The experimental design was completely randomized with six diets and 10 replications with 10 birds per experimental unit. The diets were based on corn and soybean meal: positive control -antibiotic (zinc bacitracin) + 0.05% anticoccidial (salinomycin), negative control -basal diet (BD) without additives, DB + 0.05% of salinomycin and 0.03% of oregano essential oil (Orego-Stim®), DB + 0.03% of oregano essential oil, DB + 0.05% of salinomycin and 0.05% of oregano essential oil, DB + 0.05% of oregano essential oil. There were no treatment effects on broiler performance until 21 days of age. In the other periods, at 35 and 42 days, the oregano essential oil at 0.03% combined with salinomycin presented similar effects as the positive control, leading to the conclusion that 0.03% of oregano essential oil associated with the salinomycin can replace zinc bacitracin + salinomycin in broiler chicken diets.

“…C. difficile is a known potential resident of the livestock intestinal tract and has been identified in up to 12% of sampled retail ground beef and ground pork in a Canadian study [34]. Clostridium perfringens, the leading cause of necrotic enteritis, can also become a human health issue and has been isolated as a portion of the natural microflora of the jejunum, cecum, and cloaca of poultry [35]. Listeria monocytogenes is a pathogen most commonly associated with dairy products [36].…”

Probiotics and Prebiotics in Human Nutrition and Health

Human health is a broad category that encompasses the entirety of the food production system. Livestock production practices have important effects on human health because livestock not only are a primary food source but also can be the source of pathogenic bacteria that may enter the food chain indirectly. As government regulation and public scrutiny restrict the prophylactic use of antibiotic and antimicrobial interventions, other techniques must be used to reduce the burden of animal-borne pathogenic bacteria entering the food system. Prebiotics (isolated compounds that enhance natural microflora and thereby decrease pathogens) and probiotics (live microbes that are administered to livestock to enhance microbial diversity and crowd out pathogens) represent two unique opportunities for alternative measures in pathogen reduction. This review addresses the link between animal production and human health, the agricultural sources of pathogenic organisms, and the probiotic and prebiotic approaches that have been evaluated in an effort to reduce carriage of foodborne pathogenic bacteria by livestock.Keywords: food safety, livestock, prebiotic, preharvest intervention, probiotic 1 Proprietary brand names are necessary to report factually on available data; however, the USDA neither guarantees nor warrants the standard of the product, and the use of the name by the USDA implies no approval of the product and/or exclusion of others that may be suitable.
