13. Organic acids and/or compound with defined microorganisms to control Salmonella enterica serovar Enteritidis experimental infection in chickens
The association of human foodborne salmonellosis with poultry products enhanced the efforts to control Salmonella Enteritidis in poultry farms. Dietary organic acid supplementation is one of the measures currently used to reduce the presence of undesirable microorganisms. Another method to control enteric Salmonella in poultry is competitive exclusion using

14. Isolamento e identificação de bactérias do trato entérico de avestruzes e a sua aplicação na exclusão competitiva de patógenos entéricos / Isolation and identification of ostrich enteric bacteria and its application on competitive exclusion of enteric pathogen
Bactérias da microbiota entérica de avestruzes foram isoladas e fermentadas (produto experimental denominado de ECOS). Em seguida, foram utilizadas na exclusão competitiva de Salmonella Typhimurium em pintinhos ("Gallus gallus") e em avestruzes recém nascidas ("Struthio camelus"). Os pintinhos e as avestruzes foram desafiados por via oral com a concentra

16. Study of immune response, colonization, and invasion by Salmonella enterica subsp. enterica serotype Typhimurium (1796NR) Nalr, in broiler chickens, treated with glucans, probiotics, and competitive exclusion products / Estudo da resposta imune, da colonização e invasão por Salmonella enterica subsp enterica sorotipo Typhimurium Nalr em frangos de corte, tratados com glucano, probióticos e produtos de exclusão competitiva
O efeito de sete tratamentos, contendo β-glucano, um probiótico experimental, e um produto de exclusão competitiva assim como suas associações, foram avaliados frente a um desafio com Salmonella Typhimurium Nalr e na resposta imune, em frangos de corte. Dois experimentos foram realizados; o primeiro experimento apresentou seis tratamentos que consis

17. Influência do jejum alimentar, probióticos e antibiótico na população de enterobactérias, bactérias ácido lácticas, Bacillus e Salmonella sp. em cecos e papos de frangos de corte / Influence of feed withdrawal, probiotics and antibiotic on the enterobacteria, lactic acid bacteria, Salmonella and Bacillus populations in the crop and caeca of broiler chickens
This study analyzed the population of enterobacteria and Salmonella in the crop and caeca of broiler chickens submitted to 3, 6, 9, 12, 15 and 18 hours of feed withdrawal, and raised without reutilization of the litter, in low density. The same bacteria were analyzed, plus Bacillus subtilis spores and lactic acid bacteria, in the crop and caeca of broiler ch

20. Time required to protect the intestinal tract of chicks against Salmonella enterica serovar enteritidis using competitive exclusion
Competitive exclusion (CE) has been designed to accelerate the colonization of the alimentary tract of young commercial birds and it has been also used to repopulate the digestive tract after antibiotic therapy. The method has been successfully adopted as a means to prevent enteric salmonellosis. The present study was carried out to evaluate if CE is able to

23. The molluscicidal activity of the latex of Euphorbia splendens var. hislopii on Melanoides tuberculata (Thiaridae), a snail associated with habitats of Biomphalaria glabrata (Planorbidae)
The use of the latex of Euphorbia splendens var. hislopii was considered as an effective control method for Biomphalaria glabrata in Sumidouro, Rio de Janeiro. However, the appearance and expansion of the snail Melanoides tuberculata since August 1997, with the concomitant reduction of the population of B. glabrata suggest that competitive exclusion might be

24. Complete Genome Sequence of Lactobacillus johnsonii FI9785, a Competitive Exclusion Agent against Pathogens in Poultry▿
Lactobacillus johnsonii is a member of the acidophilus group of lactobacilli. Because of their probiotic properties, including attachment to epithelial cells, immunomodulation, and competitive exclusion of pathogens, representatives of this group are being intensively studied. Here we report the complete annotated genome sequence of Lactobacillus johnsonii F
