Full textPreliminary studies aiming the identification of possible viral agents associated with the postweaning multisystemic wasting syndrome (PMWS) revealed a possible negative association between TTSuV1 and occurrence of PMWS. Based on this finding was hypothesized that TTSuV1 might be able to inhibit the PCV2 multiplication, preventing the development of PMWS. To better clarify this, would be require an efficient system of replication for this virus, which has not been reported in the literature. In view of this, a method for detection of TTSuV infections in cell culture was developed to assess possible cell lineages to be potentially used for virus isolation and multiplication. TTSuV genomes were detected in cell lineages of porcine and nonporcine origin as well as a batch of trypsin. Sera used as media supplement was not found to contain TTSuV genomes. Thus, the contaminated batch of trypsin can be considered an important source of contamination, especially in cells of non-porcine origin. In order to evaluate a possible association between the TTSuVs and the occurrence of PMWS, the frequency of detection and quantification of TTSuV1 and TTSuV2 genomes in tissues and sera from pigs with and without PMWS were determined. The analysis in the different tissues of pigs reveal an apparent inverse correlation between the frequency of detection of TTSuV1 genomes and the occurrence of PMWS. Regarding TTSuV2 in tissues of PMWS and non-PMWS-affected animals no significant differences was observed. The distribution of TTSuV1 and TTSuV2 genomes in tissues did not reveal any particular target organ. The frequency of detection and viral load of TTSuV1 and TTSuV2 in sera samples were no significant statistically among animals PMWS-affected and healthy pig. The mean of TTSuV2 viral load was significantly highest than TTSuV1 in sera of all groups studied. These results indicate a high frequency of detection of both TTSuV species in tissues and sera samples from PMWS-affected and healthy pig.

Full textAn in vitro method useful to estimate mineral bioavailability in legumes was set up and validated. The method include a gastrointestinal digestion and a cell culture (Caco-2 cells) to evaluate the uptake and transport of calcium, iron and zinc. It has been applied applied to beans, chickpeas and lentils (raw and cooked products).The Caco- 2 cell line was characterized as a model for mineral uptake and/or transport. To evaluate the cell culture state the following parameters were used: growing curves, dome formation and size, total and brush border protein content, and alkaline phosphatase and sucrase-isomaltase activities. To evaluate the cell monolayer integrity the values of transepithelial electrical resistance (TEER) and red phenol transport from the apical to the basolateral compartment were used.The cooking effect on calcium, iron and zinc uptake depends on the type of legume. In beans traditional cooking increase uptake percentages when compared to raw product, these were for Ca 21,87 and 0.57 %, Fe 29.37 and 1.66 % and Zn 15.51 and 2.12 %, for cooked and raw product, respectively. In chickpeas the contrary effect was found the higher uptake percentages correspond to raw product, Ca: 8.45 and 2.76 %, Fe: 1.83 and 1.42 % and Zn: 5.81 and 2.75 %, for raw and cooked product, respectively. Finally, in lentils the high iron uptake of ready-to-eat lentils (11.12 %) when compare to raw product (12.42 %) stand out.In raw products, the mineral classification according to the value of mineral transport depended on the legume. In beans and lentils the higher transport percentage corresponded to iron, with values of 16.3 and 42.6 %, respectively, whereas in chickpeas similar transport percentages (20 %) were found for the three elements. In lentils traditionally or industrially cooked no transported iron was detected, while the following values were found for Ca and Zn: raw products (10.10 and 12.40 %), traditionally cooked products (8 and 14,20 %) and ready-to-eat products 17 and 13 %.

Full textNeosporosis is a parasitic disease of wide distribution and great importance to the cattle industry, mainly due to its associated reproductive losses. The life cycle of Neospora caninum typified by the tree know infectious stages: tachyzoites, tissue cysts with bradyzoites, and oocysts. Transmission routes can be horizontal and/or vertical. The vertical transmission or transplacentally is the most frequent form of infection, and an important form of maintain the agent in herds. With aim of to determine the occurrence of anti-Neospora caninum antibodies in serum samples of 260 bovine fetuses, collected in a slaughter in the municipality of Santa Maria, in Rio Grande do Sul, Brazil. For detection antibodies anti-N. caninum indirect fluorescent antibody test was used and immunoglobulin G and M were detected, using a cut-off 1:25. Of the 260 serum samples tested, 15% (39/260) were positive for the presence of anti-N. caninum. Of these, in 38 the presence of IgG where detected (97.4%) and in six IgM were present (10.3%). Five samples (15.4%) tested were positive for both IgG and IgM. The results reaffirming the ability of N. caninum in determine fetal infection. The results presented on the first chapter indicated that the search of IgM anti-N. caninum is of very limited help in the detection of the transplacental infection in cattle. In second chapter, was evaluated the susceptibility to infection by N. caninum in different cell cultures, for the purpose of observe the ability in vitro multiplication this agent. For this, eight cell cultures were tested, among the cell cultures tested, four presented good susceptibility to agent: cell lines VERO (yield of 21.2 tachyzoites/cell) and MA-104 (17.1); primary bovine testicle (16.3) and lung cells (13.6). Primary bovine kidney (8.2 tachyzoites/cell), MDBK (5.1) and RK-13 cell lines (0.4) presented moderate to low sensitivity. No viable tachyzoites were detected in the culture of MDCK cells. These results demonstrate that MA-104 cells present adequate susceptibility to N. caninum compared to VERO cells, which have been largely used to multiply the parasite in vitro. Due to the easy manipulation, quick multiplication and relatively low nutritional equirements, these results indicate that MA-104 cells are adequate for multiplication of N. caninum in vitro.
A neosporose é uma doença parasitária de ampla distribuição e com grande importância para a bovinocultura, principalmente pelas perdas reprodutivas que determina. O ciclo do Neospora caninum caracteriza-se por apresentar três estágios infecciosos: os taquizoítos, os cistos teciduais contendo bradizoítos e os oocistos. Suas rotas de transmissão podem ser horizontal e/ou vertical. A infecção vertical ou transplacentária é a forma mais freqüente de infecção, sendo uma importante forma de manutenção do agente nos rebanhos. Com o objetivo de determinar a ocorrência de anticorpos anti-N. caninum em fetos bovinos, foram coletadas 260 amostras de soro em abatedouro localizado no município de Santa Maria, Rio Grande do Sul, Brasil. Para detecção de anticorpos anti-N. caninum, utilizou-se a técnica de imunofluorescência indireta com a presença de imunoglobulinas G e M (IgG e IgM), sendo analisada com ponto de corte de 1:25. Do número total de amostras testadas, 15% (39/260) foram positivas para anticorpos anti-N. caninum. Destas, em 38 (97,4%) foi detectada a presença de IgG anti-N. caninum e em seis (15,4%) de IgM. Em cinco amostras (12,8%) detectaram-se ambos, IgG e IgM. Os resultados reafirmam a capacidade do N. caninum determinar infecção fetal. Os resultados obtidos no primeiro capítulo desta dissertação permitiram demonstrar que a pesquisa de IgM foi de limitada importância na detecção da infecção via transplacentária em soro fetal bovino. No segundo capítulo, foi avaliada a susceptibilidade à infecção pelo N. caninum em diferentes cultivos celulares, com a finalidade de observar a capacidade de multiplicação deste agente in vitro. Para isto, foram testados oito cultivos, sendo que quatro apresentaram boa susceptibilidade a multiplicação pelo N. caninum: células VERO (produção de 21,2 taquizoítos/célula), MA-104 (17,1), cultivo primário de testículo (16,3) e pulmão bovino (13,6). O cultivo primário de rim bovino (8,2), células MDBK (5,1) e RK-13 (0,4) apresentaram baixa sensibilidade, enquanto células MDCK não produziram taquizoítos viáveis. Os resultados obtidos demonstram que as células MA-104 apresentaram susceptibilidade semelhante a das células VERO linhagem tradicionalmente utilizada para o cultivo deste protozoário. Pela facilidade de cultivo e rápida multiplicação, menor exigência nutricional e produção de taquizoítos em níveis semelhantes às células VERO, as células MA-104 demonstraram ser adequadas para a manutenção e multiplicação do N. caninum in vitro.

Full textLa contaminación de los cultivos celulares por Mycoplasma spp. dificulta tanto la investigación básica como el desarrollo y producción de productos biológicos. Los efectos de esta bacteria en las células cultivadas son cambios en el metabolismo, propiedades inmunológicas y bioquímicas, crecimiento, viabilidad, etc. La infección de cultivos celulares con Mycoplasma spp. puede no ser detectada por inspección visual o microscopía común, por lo tanto, es importante realizar evaluaciones periódicas de rutina con un método rápido, altamente sensible y específico. En consideración a lo anterior, esta memoria de título se basó en el diagnóstico molecular de Mycoplasma spp., mediante la detección del gen 16S rRNA utilizando la técnica de Reacción en Cadena de la Polimerasa convencional, en muestras procedentes de cultivos celulares de distintos laboratorios de la Universidad de Chile y del Instituto de Salud Pública de Chile. Los resultados obtenidos tanto en los controles positivos como en los controles negativos, permitieron validar este método en la Facultad de Ciencias Veterinarias y Pecuarias y al aplicarlo en muestras sospechosas, se logró la detección positiva en una muestra procedente del Instituto de Ciencias Biomédicas de la Universidad de Chile. Este hallazgo, fue confirmado por alineamiento de secuencias nucleotídicas respecto de datos oficiales del GenBank®, utilizando los programas Clustal W y BLAST, ambos de acceso gratuito on line que entregaron un 97% de porcentaje de identidad nucleotídica respecto de Mycoplasma spp

Full textAnimal cells have been under research as a platform for the expression of recombinant proteins, ranging from veterinary vaccines to blood coagulation factors for treating hemophilia. Examples include insect Drosophila melanogaster S2 and hamster BHK-21 cells, currently being studied for the production of rabies virus glycoprotein. Regardless of the cultivation strategy, high cell concentrations are usually associated to a higher protein production. Thus, the aim of this research was to investigate animal cell cultivation strategies that would allow higher cell concentrations than those previously reported. Cells of Drosophila melanogaster S2 expressing the rabies virus glycoprotein (S2AcGPV) were cultivated in shake flasks at 100 rpm and 28 , in SF 900 II serum-free medium supplemented with the following amino acids: asparagine, cysteine, proline, and serine. The addition of the four amino acids to the medium increased the maximum cell concentration (XV MAX) in 16%. When only cysteine was added to the medium, the maximum specific growth rate (ÊMAX) was 56% higher. In this condition, the cell yield on glucose (YX/GLC) was 47% higher, indicating a more efficient glucose metabolism. These results show that cysteine is likely a limiting substrate of S2AcGPV cells growing in SF 900 II medium. In turn, baby hamster kidney cells (BHK-21/C13), adapted to growth in suspension culture, were cultivated in perfusion, a continuous process with cell retention that allows higher cell concentration than batch or continuous cultures without cell retention. A stirred tank bioreactor with a working volume of 1.5 L was used, with an internal spin-filter with 10 µm diameter pores attached to the impeller shaft. Temperature was controlled at 37 , pH at 7.2, agitation at 80 rpm and dissolved oxygen at 50% of air saturation. The maximum cell concentration reached 15.7 x 106 cells mL-1, much higher than the cell concentration achieved in a standard batch cultivation (5 x 106 cells mL-1). Cell viability was above 90% during the 48-day cultivation period. During the batch phase of the perfusion cultivation, specific rates of glucose (qGLC) and glutamine (qGLN) consumption were 84% and 32% higher, respectively, when compared to the batch cultivation. Similarly, the specific rates of lactate (qLAC) and ammonium (qNH4) formation were 78% and 102% higher, respectively. During perfusion, the cell maintenance coefficient was not negligible and represented 83% of total glucose consumption. These data indicate that the presence of an internal spin-filter may be associated to cell stress. In perfusion, cell concentration was about 3 times higher than that in continuous culture without cell recycle. In conclusion, it was proved that suspension-adapted BHK-21 cells can be cultivated in a laboratory-scale bioreactor with an internal spin-filter, in order to achieve high cell concentrations.

Full textThe aim of this thesis is to enhance our knowledge about the mechanisms of the cell line Nicotiana tabacum BY-2 to the stress conditions, in particular, to high salinity stress. Under these conditions, the adaptation at the subcellular level implies ultrastructural modifications that allow the cells to grow. To identify the factors that may affect this adaptation process to the salinity stress and the possible modifications that may take place in the cell, electronic and light microscopy has been implemented. Additionally, potential new mechanims for subcellular uptake and accumulation of sodium have been investigated by analysing membranes vesicle trafficking (endocytosis). In this work, laser confocal in vivo techniques have been applied. Transcriptomic, proteomic and ionomic tools have been successfully used to complement these studies. Since gibberellins (GAs) are involved in the growth and elongation of plant cells, and recent studies show evidence of the association between GAs and plant tolerance to salinity conditions, the influence of GAs on the plant cells adaptation to salinity stress has also been investigated. This study has also examined, the putative changes in the GAs metabolism under the salinity stress conditions and how these changes may affect the plant cells adaptation. We are also look at the structural changes that may occur in the cell wall during the adaptation process to the salinity conditions, since this may play a major role in the control of the cell size. For this purpose, we have analyzed extensins and arabinogalactan-proteins (AGPs) by identifying their presence and distribution at the subcellular level using specific antibodies raised against epitopes of these molecules. To carry out all these objectives, several biochemical, cellular and molecular tools have been implemented to obtain an integrated view of the possible mechanisms that underlie the structural and compositional changes that occur during the adaptation process of plant cells to salinity stress and, of the regulation and effects of hormones on those changes.

Full textBPV metastatic action remains unclear. This study evaluated the BPV action on epithelial-mesenchymal transmition (EMT), using cell lines form papilloma (P), fibropapilloma (FB) and esophageal carcinoma (EC). Results showed the productive infection presence and the proliferative potential increase in these cells. However, it was verified the mitochondrial membrane potential loss in relation to normal skin (control) and the oxidative stress increase as result of E6 oncoprotein, justifying the clastogenicity and stem-cell phenotype acquisition described in P, FB and EC cells. This cell lines showed a migratory capability as result of cytoplasmic sequester of E-cadherin, and the increase levels of vimentin, vinculin and N-cadherin as consequence of STAT3 and SLUG factors activation, suggest the virus action on EMT. These results were also verified in tissue samples, reinforcing the BPV action on EMT, as well as demonstrating the potential of these cell lines as model to study the metastasis.

Full textLa apoptosis o muerte celular programada es la eliminación de células que ya no son necesarias o que están dañadas genéticamente. Es controlada por una variedad de genes, muchos de los cuales presentan mutación y/o disfuncionalidad en su regulación, asociada a cáncer. Cuando esto ocurre, los pacientes presentan tumores más agresivos. La medición morfológica cuantitativa del índice apoptótico, especialmente por microscopía de luz, es difícil ya que los cambios celulares asociados son de corta duración. En la apoptosis ocurre fragmentación del ADN, la que puede ser detectada y marcada enzimáticamente mediante la técnica denominada TUNEL (terminal transferense mediaded dUTP-biotin nick end labelling). Permite detectar estados tempranos de apoptosis, incluso antes que el núcleo experimente los primeros cambios morfológicos. El Tumor Venéreo Transmisible (T.V.T), se caracteriza por presentar una fase de crecimiento progresivo muy acelerado con gran destrucción tisular local. Sin embargo, el tratamiento con sulfato de Vincristina, a diferencia de lo que ocurre en otras neoplasias, induce la regresión de la masa tumoral hasta su completa desaparición En este trabajo se seleccionaron 10 caninos adultos con TVT de ubicación genital en fase progresiva de crecimiento para inducirles regresión tumoral con Sulfato de Vincristina en dosis única de 0.03mg/Kg. Se obtuvieron muestras histológicas para estudiar el comportamiento apoptótico del tumor después del tratamiento, mediante la técnica de inmunotinción TUNEL. Se digitalizaron imágenes que fueron analizadas con un software morfométrico (Image Pro-Plus, Media Cybernetics, USA). Se observó una intensa inmunomarcación para apoptosis en tejidos de TVT en fase regresiva, involucrando muchas células que no presentaban aún cambios morfológicos asociados a apoptosis, contrastando con una inmunomarcación ocasional, de células aisladas, en la fase progresiva de crecimiento. El área promedio de células apoptóticas fue de 51.3±37.9m2 y 1396±828.6m2, por campo de 200X, para fase progresiva y regresiva, respectivamente, indicando una diferencia significativa entre ambas fases (p<0.0001). El tipo celular principal dentro de la población apoptótica, en ambas fases, correspondió a células tumorales con un 80.7% para fase progresiva y 89.4% para fase regresiva. Mientras, que los linfocitos representaban un 16.1% y 8.4%, en las fase progresiva y regresiva, respectivamente. Las epiteliales constituían sólo un 3.2% en fase progresiva y 2.2% en fase regresiva. Dentro de la población apoptótica, las células de T.V.T. mostraron un aumento significativo en fase regresiva (p<0.001). Los linfocitos disminuyeron en forma significativa en regresión (p<0.001). En cambio, la disminución registrada en las células epiteliales en fase regresiva no fue estadísticamente significativa (p ≥0.05). Este estudio indica que la Vincristina induce regresión en T.V.T. a través de apoptosis, llevando al colapso de la masa tumoral. El mecanismo por el cual la Vincristina induciría apoptosis en T.V.T. permanece aún por aclarar, sin embargo se ha demostrado, en otras neoplasias, activación de caspasas 9 y 3, sugiriendo que este tratamiento induce apoptosis por la vía mitocondrial, involucrando mecanismos asociados a la generación de radicales derivados del oxígeno y sobre expresión de gen Bcl-2
