RESUMEN

contiene información e imágenes de parásitos obtenidas de las mismas preparaciones que observan enlas clases prácticas. Con ella pueden repasar y autoevaluar los conocimientos adquiridos. Para evaluarel proyecto, se ha permitido el acceso ilimitado a la aplicación a 74 alumnos, durante los 9 días en querealizaron sus prácticas. Las calificaciones obtenidas han sido comparadas con un grupo control de 75alumnos que realizó las prácticas el curso anterior en fechas coincidentes con las del grupo de estetrabajo y con los mismos profesores. La comparación de las calificaciones arroja un incremento mediode 0,7 puntos (sobre 10). Estudiando estos datos según rangos de puntuación, se observa que el grupoexperimental ha disminuido el porcentaje de suspensos (2,50%), incrementándose 9,95% los alumnoscon calificación ≥9,0 (sobre 10). Estos alumnos han contestado una encuesta anónima en la que nosdan su opinión acerca de la usabilidad, organización, diseño y calidad de la aplicación, suficiencia dela información aportada, utilidad de la autoevaluación, mejora del aprendizaje y resultados obtenidosen la autoevalución de la aplicación, así como su opinión sobre posibles mejoras de la misma,valorando entre 1 (pésimo) y 5 (óptimo). La encuesta, respondida por 50 alumnos de 74, arrojó unamedia global de 4,28 sobre 5. El alumnado expresó su satisfacción por contar con esta herramienta deapoyo a las prácticas(AU)

A computer application for students in "Parasitology (2nd year of Pharmacy) that contains informationand pictures of the parasites obtained from the same preparations that observed in practical classes hasbeen developed. With this computer tool, the students can review and self-evaluation their learning.For the evaluation of the project, a 74 students group was allowed unlimited access to the computerapplication during the 9 days that did their practices. The scores obtained have been compared with acontrol group of 75 students who did the practice the previous year on dates coinciding with the groupof this study and with the same teachers. The comparison of the ratings shows an average increase of0.7 points (on 10). Studying these data according to score ranges, it appears that the experimentalgroup decreased the failure rate (2.50%), increasing 9.95% rating students with ≥ 9.0 (on 10). Thesestudents have answered an anonymous survey in which they give their opinion about the usability,organization, design and quality of implementation, fitness of provided information, the utility of selfevaluation,improvement of learning and evaluation their results in the implementation as well as theirviews on possible improvements to it, from 1 (very poor) to 5 (excellent). The survey was answeredby 50 students from 74, giving an overall average of 4.28 points on 5. The students expressed theirsatisfaction with this computer tool available to support practices(AU)

RESUMEN

The authors characterize in females of Bovicola bovis the total proteins of this species by means of SDS-page determining the R(mb), Rx, Rf and mW of each protein in particular and studying finally the number of protein bands in function with their mW.

RESUMEN

The larval development of Wohlfahrtia magnifica (the most important dipteran causing sheep myiasis in the Palearctic region) has been studied by means of scanning electron microscopy. The ultrastructure of mouth-hooks, oral ridges, labial lobes, body spines and anterior and posterior peritremes is described for the first time. Their possible adaptations to a parasitic lifeway are also discussed. Thus, the use of new structures in the Sarcophagidae taxonomy is proposed from the point of view of their ultrastructure and adaptative morphology.

RESUMEN

A description of the larval development of Wohlfahrtia magnifica (Schiner, 1862) is given. An interpretation of the morphological development correlated with functional and adaptive aspects of myiasis-causing flies is also included. A detailed analysis of morphological changes that occurred in W. magnifica larvae during postembryonic development is carried out. These changes happen in 2 larval interinstars, I-II and II-III, in which several structures such as anterior and posterior peritremes and cephalopharyngeal skeleton play an important role. The possible functions of these structures are considered. We also describe the first instar in W. magnifica to differentiate it from that belonging to Sarcophaga species, paying special attention to disposition of the cephalopharyngeal skeleton, anterior peritremes, and spinulation on the last 3 segments. Several structures, not described previously in Sarcophagidae, were observed: modified spines of the buccal and peritremal cavities, peritremal tubercles, and modified spines on the ventral surface. Changes occurring in these structures during larval development are described. Their probable role in the taxonomy of the genus Wohlfahrtia and their application to Nearctic species belonging to this genus, Wohlfahrtia vigil and Wohlfahrtia opaca, are also discussed.

RESUMEN

48 bacterial isolates were gained from Bovicola spp. of Capra hircus. The distribution of the isolates among males, females and larvae suggests first conclusions on the specificity of the microflora.

RESUMEN

Bovicola limbata Gervais, 1844 has been cultured in vitro at 35 +/- 1.5 degrees and 75 +/- 5% R.H. using scrapings from goatskin and host hair as food. In these conditions its complete life cycle has been obtained. New data are given on the biology of this species: maximum, minimum and average number of eggs laid per female; reabsorbed, embryonal, hatched and unhatched eggs; percentage of specimens that reached the second, third and adult instars; mortality percentage in the first, second and third instars.
