Résumé :
The mixotrophic ciliate Mesodinium rubrum is an ambush feeder relying on cryptophyte prey motility for prey encounter and perception; therefore, cryptophyte species-specific swimming behaviors affect M. rubrum’s prey preference. Here, a high-speed microscale imaging system was used to quantify the swimming behaviors of 3 cryptophyte species (Teleaulax amphioxeia, Storeatula major, and Guillardia theta) and to conduct quantitative microvideography of M. rubrum-T. amphioxeia predator-prey interaction. T. amphioxeia, a preferred prey of M. rubrum, swam at path-averaged speeds of 155 ± 73 µm s-1 along rather straight paths. In contrast, S. major regularly tumbled slowly downward or upward at 64 ± 16 µm s-1, while G. theta moved slowly in looped/curved trajectories at 57 ± 15 µm s-1; neither supports M. rubrum growth. Only while motionlessly sinking passively did M. rubrum detect and initiate an attack on swimming T. amphioxeia at reaction distances of 8.2 ± 8.2 µm. It seemed that M. rubrum needed to use oral tentacles to initially poke T. amphioxeia’s ventral posterior part and subsequently poke the prey multiple times in a short duration to compromise the prey’s escape ability, presumably by discharging extrusomes into the prey. T. amphioxeia also responded to nearby predators by switching to tumbling similar to S. major in normal swimming, suggesting an effective anti-predator defense behavior that prevents M. rubrum from accurately poking the prey’s ventral posterior part. T. amphioxeia swimming at significantly higher speeds leads to sufficiently high prey encounters and hydrodynamic signals for M. rubrum, thereby partially explaining M. rubrum’s ability to select T. amphioxeia prey.

Résumé :
Trichophyton rubrum, an anthropophilic and cosmopolitan fungus, is the most common agent of superficial mycoses. In this study, T. rubrum infection was modelled by adding human skin sections to a limited medium containing glucose and cDNA microarrays were used to monitor T. rubrum gene expression patterns on a global level. We observed that exposure to human skin resulted in upregulation of the expression levels of T. rubrum genes related to many cellular and biological processes, including transcription and translation, metabolism and secondary transport, the stress response, and signalling pathways. These results provide a reference set of T. rubrum genes whose expression patterns change upon infection and reveal previously unknown genes that most likely correspond to proteins that should be considered as virulence factor candidates and potential new drug targets for T. rubrum infection.

Résumé :
Neutrophils are the first leukocytes recruited to the site of infection and are thought to be responsible for fungal elimination from the skin such as dermatophytes. Neutrophils are able to secrete reactive oxygen species (ROS) and neutrophil extracellular traps (NETs) that can kill different fungi, including Aspergillus, spp., Candida albicans, and Phialophora verrucosa. However, NET production in response to Trichophyton rubrum, the main etiologic agent of dermatophytosis, has yet to be studied. We demonstrated that human neutrophils produce NETs against different morphotypes of T. rubrum in a dose-dependent manner and NET formation is dependent on ROS production. In addition, ROS production by human neutrophils in response to T. rubrum is dependent on NADPH oxidase, but not on fungal viability. NETs mediated killing of T. rubrum. Collectively, these results demonstrate that T. rubrum was able to trigger the production of NETs, suggesting that these extracellular structures may represent an important innate immune effector mechanism controlling physiological response to T. rubrum infection.

Cataloged from PDF version of thesis.
Includes bibliographical references (p. 22-24).
Sedimentary rocks of all ages abound with geostable lipids of microbial origin, but many biomarkers lack known organismal sources and clear environmental contexts. Here we used Rhodospirillum rubrum, a metabolically versatile, genetically tractable c-Proteobacterium, to explore the diversity of its non-polar terpenoids as a function of growth condition and growth phase. We analyzed the nonpolar fraction of lipids extracted from R. rubrum grown under aerobic, anaerobic, heterotrophic and phototrophic conditions and detected a variety of bicyclic, tricyclic, tetracyclic and pentacyclic triterpenoids, derived from the enzymatic cyclization of squalene and produced in amounts comparable to diploptene. Identified compounds included bicyclic polypodatetraenes, malabaricatriene, euphadiene, adianane, and fernene. Prior to this work, malabaricatriene was an "orphan" biomarker suspected to have a microbial origin, yet it lacked a proven source. We observed similar patterns of polycyclic terpenoids in other hopanoid-producing c-proteobacteria, including Zymomonas mobilis, Rhodopseudomonas palustris, and Rhodomicrobium vannielii. The presence and relative abundance of polycyclic triterpenoids in R. rubrum varied with the growth stage (exponential versus early stationary phase) and growth condition (photoheterotrophic versus photoautotrophic growth). Since R. rubrum's genome contains a single squalene-hopene cyclase gene, the array of triterpenoids produced by it and other c-proteobacteria likely evolves from this enzyme performing low-fidelity cyclization. The observed diversity of sedimentary triterpenoids might therefore result from a select few squalene-hopene cyclase enzymes operating with varying specificity under a range of physiological and environmental conditions, rather than reflecting a great diversity of squalene-hopene cyclases.

Résumé :
Dermatofitoses são comumente causadas por fungos que parasitam pele e unha de humanos, cuja propagação depende do contato entre os hospedeiros infectados e não infectados. Muitos fatores contribuem para a patogenicidade dos dermatófitos, dentre eles, a capacidade de se instalar no ambiente ácido da pele se reveste de importância. Sendo assim, para ser bem sucedido, o dermatófito precisa ter capacidade aderente, germinação e penetração rápida das hifas e, portanto, dispor de uma maquinaria metabólica que atue de forma eficiente em pH ácido. A fim de identificar genes supostamente expressos nos passos iniciais da infecção, submetemos a linhagem H6 do dermatófito T. rubrum ao pH ácido por 30 minutos e 1 hora e isolamos dessas condições experimentais os transcritos com elevada expressão, empregando a metodologia de Biblioteca Subtrativa Supressiva (SSH). Obtivemos um total de 234 unigenes cujos transcritos revelaram ampla diversidade funcional. Esses transcritos estão envolvidos em 13 processos celulares diferentes, tais como, metabolismo, defesa e virulência, síntese de proteínas e transporte celular. Desses, confirmamos por Northern blotting, os genes que expressam as proteínas carboxipeptidase S1, acetoamidase, aconitase, dessaturase, a proteína TINA, transportador de aminoácidos, fator de alongamento alfa 1, proteína ribossomal L10, e uma proteína hipotética. Nesses experimentos também foi utilizada a linhagem de T. rubrum pacC-1, que tem o seu gene pacC rompido, com o objetivo de verificar se estes genes isolados seriam regulados pela proteína PacC. O gene pacC codifica uma proteína homóloga ao regulador transcricional PacC/Rim101p da conservada via de sinalização do pH. Verificamos que o gene pacC se expressa preferencialmente em pH 8.0 e que embora o padrão de processamento da proteína PacC seja dependente do pH a forma íntegra da proteína PacC foi identificada tanto em pH ácido como alcalino. Por outro lado, o mutante pacC-1 apresentou diminuida capacidade infectiva em fragmentos de unha humana quando comparado com a linhagem selvagem. Além disto, a atividade queratínolitica do mutante também se mostrou diminuída quando comparada ao controle, confirmando o papel da proteína PacC na capacidade infectiva do T. rubrum.
Dermatophytosis is commonly caused by fungi that parasite human skin and nail, whose propagation depends on the contact between infected and noninfected hosts. Many factors contribute to the pathogenicity of the dermatophytes. Among them, the capacity to install in the skin´s acid ambient bears great importance. Thus, in order to be successful, the dermatophyte needs to have adhering capacity, fast germination and penetration of hyphae and, therefore, needs to afford a metabolic machinery which acts efficiently in acid pH. In order to identify genes supposedly expressed in the initial steps of infection, we submitted the strain H6 of the dermatophyte T. rubrum to the acid pH for 30 minutes and 1 hour and isolated, from this experimental conditions, the transcripts with high expression, employing the suppression subtractive hybridization (SSH). We obtained a total of 234 unigenes whose transcripts revealed a wide functional diversity. These transcripts are involved in 13 different cell processes, such as metabolism, defense and virulence, protein synthesis and cell transport. Among these, we confirmed through Northern blotting the genes which express the proteins carboxipeptidase S1, acetamidase, aconitase, fatty acid desaturase, NIMA interactive protein (TINA), amino acid permease, elongation factor 1-alpha, 60S ribosomal protein L10 and a hypothetical protein. In these experiments, we also used the T. rubrum pacC- 1 strain, which has its pacC gene disrupted, aiming at verifying whether these isolated genes would be regulated by the PacC protein. The pacC gene encodes a protein homologous to the PacC/Rim101p transcriptional regulator of the conserved route of pH signaling. We verified that the pacC gene is expressed preferentially in both pH, and that although the processing pattern of the PacC protein is dependent on the pH, the full form of the PacC was identified as alkaline. On the other hand, the pacC-1 mutant presented diminished infecting capacity in human nail fragments when compared to the wild strain. Moreover, the keratinolytic activity of the mutant also seemed diminished when compared to the control, confirming the role of the PacC protein in the infecting capacity of T. rubrum.

Résumé :
A regulação da expressão gênica é essencial para os fungos se adaptarem às adversidades ambientais, como alterações no pH extracelular, escassez de nutrientes, força iônica e oscilações de temperatura. A resposta adaptativa ao pH ambiente é bem caracterizada em fungos modelo como Aspergillus nidulans, e envolve a via de transdução de sinal constituída pelos produtos dos genes pal e pacC. No dermatófito Trichophyton rubrum, o gene pacC foi inativado, e a linhagem mutante apresentou uma diminuição na atividade das queratinases, indicando que, de alguma forma, este gene está envolvido na regulação da atividade queratinolítica deste dermatófito, e consequentemente na sua virulência e patogenicidade. Além disto, a glicosilação protéica é uma importante forma de regulação pós traducional, estruturando e estabilizando glicoproteínas que podem ser da via secretória, da parede ou da membrana celular. O processo de glicosilação protéica sofre influência do pH extracelular e da fonte nutricional. Foi ainda relatado que este tipo de regulação pós traducional também sofre influência dos genes palB e pacC, indicando que estes genes tenham um papel na glicosilação de enzimas secretadas. O objetivo deste trabalho foi analisar a influência do pH e da fonte nutricional na expressão de genes que codificam enzimas de N- e O-manosilação, e sua possível modulação pela proteína PacC no dermatófito T. rubrum. Para tanto, foi analisado, por PCR em tempo real, o perfil transcricional destes genes nas linhagens H6 (controle) e pacC-1, utilizando-se como fonte de carbono glicose, glicose e glicina ou queratina em vários tempos de cultivo, em pH 5,0 ou 8,0. A análise da expressão gênica revelou que quando a linhagem controle é cultivada em queratina em pH 5,0 ocorre um aumento da expressão da O-manosiltransferase, comparado com o cultivo em glicina com glicose e glicose. Porém, nestas mesmas condições o gene da N-manosiltransferase da linhagem mutante apresenta maiores níveis de expressão que os da linhagem controle. Em pH 8,0 pode-se notar grande semelhança entre os perfis de expressão apresentados por estes dois genes. Os resultados obtidos indicam que o gene pacC tem um papel importante no sensoriamento de nutrientes em meio ácido, modulando a expressão destas transferases, nas condições avaliadas. Estas enzimas podem ativar proteínas que atuam na hidrólise da queratina, ou mesmo formar glicoproteínas de parede celular que são essenciais na adesão do fungo à célula do hospedeiro, sugerindo um papel das manosiltransferases no processo infeccioso.
Gene expression regulation is essential for fungi to adapt to environmental adversities, such as changes in the extracellular pH, nutrient starvation, ionic strength, and temperature. The adaptive response to ambient pH is well characterized in model fungi such as Aspergillus nidulans, and involves the signal transduction pathway consisting of the products of the pal and pacC genes. In the dermatophyte Trichophyton rubrum, the pacC gene was inactivated and the mutant strain showed a decreased activity of keratinases, indicating that, somehow, this gene is involved in the regulation of the keratonolytic activity of this dermatophyte, and consequently in its virulence and pathogenicity. Moreover, protein glycosylation is an important form of post-translational regulation, playing a role in protein folding and stability of glycoproteins of the secretory pathway, cell wall or membrane. The process of protein glycosylation is influenced by extracellular pH and nutritional source. It has also been reported that this type of post-translational regulation is also influenced by the palB and pacC genes, indicating that these genes have a role in glycosylation of secreted enzymes. The objective of this study was to analyze the influence of the pH and nutritional source in the expression of the genes coding for the N-and O-manosylation enzymes, and their possible modulation by PacC in the dermatophyte T. rubrum. To this end, the transcriptional profile of these genes was analyzed, by Real Time PCR, in the H6 (control) and pacC-1 strains, using glucose, glucose with glycine, or keratin as the carbon source, in several culture times, at pH 5.0 or 8.0. Gene expression analysis showed that when the control strain is grown in keratin at pH 5.0 there is an increased expression of the O-manosyltransferase encoding gene, compared to the cultivation in glucose and glucose with glycine. However, at the same conditions the gene coding for the N-manosyltransferase presented higher levels of expression in the mutant strain in relation to the control strain. At pH 8.0 there is a great similarity between the expression profile of these two genes. The obtained results indicate that pacC gene plays an important role in nutrient sensing at acidic pH by modulating the expression of these transferases in the conditions evaluated. These enzymes can activate proteins that play roles in the hydrolysis of keratin, or even forming cell wall glycoproteins that are essential for the adhesion of the fungus to the host cell, suggesting a role of the manosyltransferases in the infectious process.

Résumé :
La presente tesis está enmarcada en el desarrollo de los sistemas de soporte de vida biológicos, de especial aplicación para los viajes espaciales tripulados de larga duración.
Concretamente, este trabajo se centra en el estudio, análisis, modelización y escalado de uno de los cinco compartimentos que integran el bucle MELiSSA, el compartimento fotoheterotrófico.
Los experimentos han sido encaminados a determinar la influencia de la naturaleza de la radiación, de la irradiancia incidente y de la naturaleza y concentración de la fuente de carbono sobre la velocidad de crecimiento de las células de R. rubrum.
También se ha analizado las consecuencias del cambio de escala del fotobiorreactor, observando la particular influencia de las condiciones ambientales en la composición y en el crecimiento de las células de R. rubrum.
La información experimental obtenida ha servido para la construcción de un modelo que predice el crecimiento de las células en función de la concentración de fuente de carbono y de la cantidad de radiación subministrada. En una primera fase se calcula el perfil de irradiancia en el interior del cultivo en función de la irradiancia incidente, de la concentración de células y de las dimensiones del fotobiorreactor, y después este perfil es utilizado para determinar la velocidad de crecimiento de las células teniendo también en consideración las condiciones de cultivo.
Asimismo, el modelo se ha utilizado como una herramienta para el dimensionado del fotobiorreactor piloto a una escala suficiente para conseguir los objetivos de demostración fijados en el Proyecto MELiSSA.
Finalmente, se ha diseñado el fotobiorreactor a escala piloto, así como todos los equipos auxiliares necesarios (depósitos pulmones, válvulas, sondas, circuito de esterilización, lazos de control, caudalímetros, etc.) para la operación del compartimento en condiciones estériles durante largos periodos de tiempo.
The present thesis is developed in the mark of the development of biological support systems for the long-term space manned missions.
Specifically, this study is centred in the analysis and scale-up of one of the five compartments that integrate the MELiSSA loop, the photoheterotrophic compartment.
The experiments have been designed to determine the influence of the nature of the radiation, the incident irradiance and the nature and concentration of the carbon source on the growth rate of R. rubrum cells. Moreover, it has been studied the consequences of the scale-up of the photobiorreactor and it has been observed that the influence of the environmental conditions in the composition and the growth rate of R. rubrum cells is a key factor.
The experimental data obtained has been used for the construction of a model, which is developed, calibrated and validated in this thesis. The model predicts the growth of the cells based on two parameters: the concentration of carbon source in the culture and the amount of radiation supplied. In a first step, the profile of irradiance inside the culture is calculated, which depends on the concentration of cells and the dimensions of the fotobiorreactor. Then, in a second step, the profile of irradiance is used to determine the cells growth rate.
Moreover, the model has been used as a tool for the sizing of the fotobiorreactor at pilot scale. And, finally, the pilot fotobiorreactor has been designed, as well as all of the auxiliary equipment that is needed (buffer tanks, valves, sensors, circuit of sterilization, control loops, mass flowmeters, etc.) for the operation of the photobiorreactor in sterile conditions during long periods of time.

Résumé :
ABSTRACT Background: Trichophyton rubrum is an infectious dermatophyte fungus which is the most common cause of dermatophytosis. Fungal resistance and the side effects of therapy are problems of antifungal agents. Phytochemical test of brotowali stem extract (Tinospora crispa) consist of flavonoids, phenols and triterpenoids which have antifungal effects. This study aimed to examine the effectiveness of brotowali stem extract (Tinospora crispa) as antifungal agent towards the growth of Trichophyton rubrum in vitro using agar well diffusion method. Subjects and Method: This was an experimental study using brotowali stem extract with concentration of 10%, 12,5%, 25%, 30%, 40%, 50%, 60%, 75%, and 100%. The dependent variable was Trichophyton rubrum growth. The independent variable was brotowali stem extract (Tinospora crispa). The data were obtained from the inhibition zone showed in agar well diffusion method in Sabouraud Dextrose Agar media. The data were analyzed using Kruskal-Wallis test. Results: The average diameter of inhibition zone of each variance (10%, 12,5%, 25%, 30%, 40%, 50%, 60%, 75%, and 100%) were 2.167 mm, 6.367 mm, 7.0 mm, 10.67 mm, 119 mm, 13.07 mm, 15.8 mm, 17.96 mm dan 17.13 mm, respectively, and they were statistically significant (p= 0.001). Conclusion: Brotowali stem extract has weak antifungal effectiveness at concentration 10%, 12,5%, 25%, intermediate antifungal effectiveness at concentration 30% and strong antifungal effectiveness at concentration 40%, 50%, 60%, 75% and 100%.

Résumé :
Tinea pedis is the most common type of fungal infection in human. The samples have been taken from fifty patients (26 female, 24 male) their ages ranged from 11 to over 60 years diagnosed as having Tinea pedis in Baghdad Teaching Hospital. All samples were examined directly after the addition of a drop of 10% KOH solution and then cultured on selective fungal culture media. The results showed that the rate of infection was more in females, and more in patients with age ranging from (30-39) years old, followed by those between (40-49) years old, and the causative fungi agents of fungal infection of T. pedis were mainly Trichophyton rubrum (72%) followed by Trichophyton mentagrophyte (32%) then Epidermophyton floccosum (12%) respectively. The inhibitory effect of alcoholic extract of Anchusa strigosa was tested in vitro on some causative fungi of Tenia pedis and the result were Compared with that of Antifungal Tolnaftate, and the result of it showed that Trichophyton mentagrophyte was affected by the extract more than Trichophyton rubrum and the percentage of growth inhibition by the extract for Trichophyton mentagrophyte at a concentration of (500) and (1000) P.P.M. were (65.11% and 100%) respectively, while that for Trichophyton rubrum were (53.68%, 87.36% and 100%) at a concentration of (500, 1000 and 1500) P.P.M. respectively. This extract was shown to be a promising antifungal agent in the future. Key words: Anchusa Strigosa, Tinea Pedis, Alcoholic Extract, Dermatophytes, Tolnaftate.
