Desempenho, rendimento de carcaça e excreção de cálcio de frangos de corte alimentados com diferentes níveis de aminoácidos e cálcio no período de 22 a 42 dias de idade

Um experimento foi conduzido com o objetivo de avaliar diferentes níveis de aminoácidos e de cálcio para frangos de corte no período de 22 a 42 dias de idade. Avaliou-se o desempenho, o rendimento de carcaça e a excreção de cálcio. Foram utilizadas 540 aves, machos, da marca comercial Cobb, distribuídas em delineamento inteiramente casualizado, em esquema fatorial 3x2, ou seja, 3 níveis de aminoácidos (metionina, metionina+cistina, lisina e treonina - 100%, 125% e 150% NRC,1994) e 2 níveis de cálcio (75% e 100% NRC,1994), com 3 repetições de 30 aves cada. Os aminoácidos estudados foram metionina, metionina+cistina, lisina e treonina. O desempenho das aves foi avaliado pelo peso vivo, ganho de peso, consumo de ração e conversão alimentar. O rendimento de carcaça e a percentagem de cada parte foram avaliados de 2 aves de cada repetição, escolhidas ao acaso, perfazendo um total de 6 animais por tratamento. O rendimento de carcaça foi realizado após o abate levando-se em consideração a percentagem de peito, pernas (coxa+sobrecoxa), asas, dorso, cabeça+pescoço e pés em relação à carcaça eviscerada. Além disso, analisou-se o cálcio excretado pelas aves. Para tanto, utilizou-se 72 aves, alojadas em gaiolas, seguindo o mesmo delineamento descrito anteriormente. Não houve interação entre os fatores estudados para as características avaliadas. As que consumiram dietas com 125% e 150% de aminoácidos apresentaram melhor conversão alimentar. O rendimento de peito foi afetado pelos níveis de cálcio.

Utilização de subprodutos de origem animal em dietas formuladas com base em proteína bruta e proteína ideal para frangos de corte de 22 a 42 dias de idade

Foi conduzido um experimento para avaliar a utilização de subprodutos de origem animal em dietas para frangos de corte de 22 a 42 dias de idade, formuladas com base nos conceitos de proteína bruta e proteína ideal. O delineamento foi inteiramente casualizado em esquema fatorial 2x2+1, ou seja, duas fontes de proteína de origem animal (farinha de vísceras de aves e farinha de sangue bovino), dois conceitos de formulação (proteína bruta e proteína ideal) e uma dieta controle à base de milho e farelo de soja, com quatro repetições. As características avaliadas foram ganho de peso, consumo de ração, conversão alimentar, rendimentos de carcaça e de peito e gordura abdominal. O ganho de peso, consumo de ração e conversão alimentar não foram afetados pelas fontes de proteína e conceitos de formulação, no entanto, o teor de gordura abdominal foi menor nas aves alimentadas com farinha de vísceras que naquelas alimentadas com dieta contendo farinha de sangue.

Influence of Yersinia pseudotuberculosis outer proteins (Yops) on interleukin-12, tumor necrosis factor alpha and nitric oxide production by peritoneal macrophages

An essential key to pathogenicity in Yersinia is the presence of a 70 kb plasmid (pYV) which encodes a type-III secretion system and several virulence outer proteins whose main function is to enable the bacteria to survive in the host. Thus, a specific immune response is needed in which cytokines are engaged. The aim of this study was to assess the influence of Yersinia outer proteins (Yops) released by Yersinia pseudotuberculosis on the production of the proinflammatory cytokines, interleukin-12 (IL-12), and tumor necrosis factor alpha (TNF-alpha), and nitric oxide (NO) by murine peritoneal macrophages. To this end, female Swiss mice were infected intravenously with wild-type Y pseudotuberculosis or with mutant strains unable to secrete specific Yops (YopE, YopH, YopJ, YopM, and YpkA). on the 7th, 14th, 21st, and 28th days after infection, the animals were sacrificed and the cytokines and NO were assayed in the peritoneal macrophages culture supernatants. A fall in NO production was observed during the course of infection with all the strains tested, though during the infection with the strains that did not secrete YopE and YopH, the suppression occurred later. There was, in general, an unchanged or sometimes increased production of TNF-alpha between the 7th and the 21st day after infection, compared to the control group, followed by an abrupt decrease on the last day of infection. The IL-12 production was also suppressed during the infection, with most of the strains tested, except with those that did not secrete YopJ and YopE. The results suggest that Yops may suppress IL-12, TNF-alpha, and NO production and that the most important proteins involved in this suppression are YopE and YopH. (C) 2004 Elsevier B.V.

Interleukin-15 increases Paracoccidioides brasiliensis killing by human neutrophils

Interleukin-15 is a pro-inflammatory cytokine produced by a wide range of different cell types, especially monocytes and macrophages, in response to infective agents, playing a crucial and modulatory role in innate and adaptive immune response. Infections by intracellular microorganisms such as some bacteria, protozoa and fungi point out the role of IL-15 in the activation of monocytes/macrophages and neutrophils, a process that represents an important defense mechanism in early periods of infection during the development of innate immune response. The aims of the present study were to evaluate the effects of IL-15 on human neutrophil fungicidal activity against a high virulent Paracoccidioides brasiliensis strain ( Pb18) and to verify whether this activity was mediated by oxidative metabolism such as the production of superoxide anion and H2O2 and if it was associated with an alteration of cytokine ( IL-8 and TNF-alpha) levels. Neutrophils from peripheral blood of healthy individuals were incubated in the presence and absence of IL-15 ( 12.5 - 250ng/ml) for 18h, at 37 degrees C, under tension of 5% CO2, then infected with Pb18 for 4h and evaluated for fungicidal activity, production of superoxide anion and H2O2, and quantification of cytokines IL-8 and TNF-a in the supernatant. Preincubation of neutrophils with IL-15 induced a significant increase in the fungicidal activity of such cells in a dose-dependent manner. After activation, there was an increase in the production of superoxide anion and H2O2 by these cells, suggesting participation of such metabolites in fungicidal activity. Catalase inhibits fungicidal activity, confirming the role of H2O2 in fungus killing. However, the levels of TNF-alpha and IL-8 were not modified after incubation with IL-15, which suggests that its role is not mediated by those cytokines. Taken together, results showed that IL-15 had a modulatory effect on human neutrophils infected in vitro with a high virulent strain of P. brasiliensis, which was characterized by an increased fungicidal activity mediated by a dependent mechanism of oxidative metabolism.

Genetic, epidemiological and biological analysis of interleukin-10 promoter single-nucleotide polymorphisms suggests a definitive role for-819C/T in leprosy susceptibility

Leprosy is a complex infectious disease influenced by genetic and environmental factors. The genetic contributing factors are considered heterogeneous and several genes have been consistently associated with susceptibility like PARK2, tumor necrosis factor (TNF), lymphotoxin-alpha (LTA) and vitamin-D receptor (VDR). Here, we combined a case-control study (374 patients and 380 controls), with meta-analysis (5 studies; 2702 individuals) and biological study to test the epidemiological and physiological relevance of the interleukin-10 (IL-10) genetic markers in leprosy. We observed that the -819T allele is associated with leprosy susceptibility either in the case-control or in the meta-analysis studies. Haplotypes combining promoter single-nucleotide polymorphisms also implicated a haplotype carrying the -819T allele in leprosy susceptibility (odds ratio (OR) = 1.40; P = 0.01). Finally, we tested IL-10 production in peripheral blood mononuclear cells stimulated with Mycobacterium leprae antigens and found that -819T carriers produced lower levels of IL-10 when compared with noncarriers. Taken together, these data suggest that low levels of IL-10 during the disease outcome can drive patients to a chronic and unprotective response that culminates with leprosy.
