Este no ha sido un año más en mi vida, he tenido que pasar por muchas cosas que me han marcado profundamente y hay tantas cosas y tantas personas a las que tengo que agradecer que es difícil saber por dónde empezar. Voy a empezar por agradecerle a mi esposa Noelia por darle luz a mi vida y dos hermosas hijas Julieta y Lucia, esta última por llegar a este mundo en breve. Me resulta difícil pensar que este trabajo me demandó el mismo tiempo que formar una familia. Aun me cuesta creer que hace 5 años recién comenzábamos a conocernos y dábamos el gran paso de irnos a vivir juntos y hoy hemos logrado construir a base de comprensión y sacrificio una hermosa familia. Sin lugar a dudas mis hijas son la mejor recompensa que puedo recibir en esta vida. No puedo dejar de agradecer a mis padres Blanca y Coco por apoyarme en mis decisiones y presionarme lo justo y necesario para que me esfuerce cada día en busca de lograr mis objetivos. No puedo dejar de pensar en lo importante que han sido mis directores Carlos Lange y María Marta Cigliano quienes confiaron en mí y me ayudaron a formarme no solo como profesional, sino también como persona mostrando el camino por el que uno debe transitar más allá de lo crudo y frio del sistema científico argentino. Una vez más me resulta difícil dimensionar el tiempo que ha pasado desde aquel día en el que ingrese por primera vez al laboratorio 1 del CEPAVE, sin saber siquiera bien lo que quería. Allí me esperaban los por aquel entonces Becarios ahora convertidos en investigadores Santiago y Yanina, dos grandes compañeros de trabajo y amigos. A la Dra. María Laura de Wysiecki por su apoyo en el diseño de experiencias y su cálida compañía en el laboratorio. A mis tíos Ricardo, Ana y Rubén quienes siempre estaban dispuestos a recibirme en el campo con un rico asado. A los chicos del ciber por las largas charlas acompañadas de mates que hicieron más ameno el trabajo de gabinete. A la Dra. Mariana Grossi, por su compañía incondicional y la realización de los mapas de esta tesis. A Santiago y Ale por las constantes visitas y por ofrecerse a ayudar en los momentos más difíciles. Al padrino ausente Fernando por apoyar a la distancia. A Nela y Gisel por su colaboración en las tareas de campo. A todo el equipo médico que intervino de manera brillante para que hoy pueda escribir estas palabras. A todos los mencionados y a aquellos que seguramente estoy olvidando. Gracias! ii Biología y biocontrol de Dichroplus elongatus, acridio plaga del agro en Argentina Los acridios, comúnmente denominados tucuras o langostas, pertenecen a la superfamilia Acridoidea. En Argentina, de las 203 especies conocidas al menos 15 han sido mencionadas como responsables de causar pérdidas al agro, destacándose entre ellas Dichroplus elongatus Giglio-Tos. Su amplia distribución y aparente plasticidad respecto de su tolerancia a diferentes ambientes parecen haber contribuido a que dicha especie resulte “beneficiada” con el desarrollo de ambientes disturbados asociados a los agroecosistemas. Dichroplus elongatus además suele ser tanto en situaciones de explosiones demográficas o de recesión poblacional de acridios, la especie dominante en los hábitats de pastizal. Dada su importancia como plaga y su dominancia numérica en las comunidades de acridios, se torna fundamental profundizar el estudio de la biología de D. elongatus y sus patógenos asociados. El objetivo central de este trabajo fue el de llevar a cabo estudios que permitan conocer algunos aspectos biológicos fundamentales de D. elongatus y de algunos de sus entomopatógenos asociados como potenciales agentes de biocontrol con el fin de poder regular sus poblaciones. En este contexto, se contempló corroborar el estatus como plaga agrícola de D. elongatus, esclarecer un aspecto fundamental

Box 1346 Ann Arbor, Ml 48106-1346 ABSTRACT A study on the cell biology of motility inEimeria tenella sporozoites Eimeria tenella is an obligate intracellular parasite within the phylum Apicomplexa. It is the causative agent of coccidiosis in domesticated chickens and under modem farming conditions can have a considerable economic impact. Motility is employed by the sporozoite to effect release from the sporocyst and enable invasion of appropriate host cells and occurs at an average speed of 16.7 ± 6 pms'\ Frame by frame video analysis of gliding motility shows it to be an erratic non­ substrate specific process and this observation was confirmed by studies of bead translocation across the cell surface occurring at an average speed of 16.9 ± 7.6 pms'^ Incubation with cytochalasin D, 2,3-butanedione monoxime and colchicine, known inhibitors of the motility associated proteins actin, myosin and tubulin respectively, indicated that it is an actomyosin complex which generates the force to power sporozoite motility.

Graham Clark Urosporids (Apicomplexa: Urosporidae) are eugregarines that parasitise marine invertebrates, such as annelids, molluscs, nemerteans and echinoderms, inhabiting their coelom and intestine. Urosporids exhibit considerable morphological plasticity, which correlates with their different modes of motil- ity and variations in structure of their cortical zone, according to the localisation within the host. The gregarines Urospora ovalis and U. travisiae from the marine polychaete Travisia forbesii were investigated with an emphasis on their general morphology and phylogenetic position. Solitary ovoid trophozoites and syzygies of U. ovalis were located free in the host coelom and showed metabolic activity, a non-progressive movement with periodic changes of the cell shape.

LEANDER Canadian Institute for Advanced Research, Program in Integrated Microbial Biodiversity, Departments of Botany and Zoology, University of British Columbia, #3529 6270 University Boulevard, Vancouver, BC, Canada V6T 1Z4 ABSTRACT. The trophozoites of two novel archigregarines, Selenidium pisinnus n. sp. and Filipodium phascolosomae n. sp., were described from the sipunculid Phascolosoma agassizii. The trophozoites of S. pisinnus n. sp. were relatively small (64–100 mm long and 9–25 mm wide), had rounded ends, and had about 21 epicytic folds per side. The trophozoites of F. phascolosomae n. sp. were highly irreg- ular in shape and possessed hair-like surface projections. The trophozoites of this species were 85–142 mm long and 40–72 mmwideand possessed a distinct longitudinal ridge that extended from the mucron to the posterior end of the cell. In addition to the small subunit (SSU) rDNA sequences of these two species, we also characterized the surface morphology and SSU rDNA sequence of Selenidium orientale,isolated from the sipunculid Themiste pyroides. Molecular phylogenetic analyses demonstrated that S. pisinnus n. sp. and S. orientale formed a strongly supported clade within other Selenidium and archigregarine-like environmental sequences. Filipodium phascolosomae n. sp. formed the nearest sister lineage to the dynamic, tape-like gregarine Selenidium vivax.

We employed an expressed sequence tag strategy in order to dissect the molecular processes of sexual or gametocyst development of gregarines. Expressed sequence tags provide a rapid way to identify genes, particularly in organisms for which we have very little molecular information. Analysis of w1800 expressed sequence tags from the gametocyst stage revealed highly expressed genes related to cell division and differentiation. Evidence was found for the role of degradation and recycling in gametocyst development. Numerous additional genes uncovered by expressed sequence tag sequencing should provide valuable tools to investigate gametocyst development as well as for molecular phylogenetics, and comparative genomics in this important group of parasites. q 2004 Australian Society for Parasitology Inc.

  • Where Gliding Motility Originates? Valigurová Et Al
    The enigma of eugregarine epicytic folds: where gliding motility originates? Valigurová et al. Valigurová et al. Frontiers in Zoology 2013, 10:57 http://www.frontiersinzoology.com/content/10/1/57 Valigurová et al. Frontiers in Zoology 2013, 10:57 http://www.frontiersinzoology.com/content/10/1/57 RESEARCH Open Access The enigma of eugregarine epicytic folds: where gliding motility originates? Andrea Valigurová1*, Naděžda Vaškovicová2,Naďa Musilová1 and Joseph Schrével3 Abstract Background: In the past decades, many studies focused on the cell motility of apicomplexan invasive stages as they represent a potential target for chemotherapeutic intervention. Gregarines (Conoidasida, Gregarinasina) are a heterogeneous group that parasitize invertebrates and urochordates, and are thought to be an early branching lineage of Apicomplexa. As characteristic of apicomplexan zoites, gregarines are covered by a complicated pellicle, consisting of the plasma membrane and the closely apposed inner membrane complex, which is associated with a number of cytoskeletal elements. The cell cortex of eugregarines, the epicyte, is more complicated than that of other apicomplexans, as it forms various superficial structures. Results: The epicyte of the eugregarines, Gregarina cuneata, G. polymorpha and G. steini, analysed in the present study is organised in longitudinal folds covering the entire cell. In mature trophozoites and gamonts, each epicytic fold exhibits similar ectoplasmic structures and is built up from the plasma membrane, inner membrane complex, 12-nm filaments, rippled dense structures and basal lamina. In addition, rib-like myonemes and an ectoplasmic network are frequently observed. Under experimental conditions, eugregarines showed varied speeds and paths of simple linear gliding. In all three species, actin and myosin were associated with the pellicle, and this actomyosin complex appeared to be restricted to the lateral parts of the epicytic folds.
