Peptidázy monogeneí čeledi Diplozoidae / Peptidases of monogeneans of the family Diplozoidae

Jedličková, Lucie January 2013 (has links)
The blood processing mechanisms in monogeneans of the subclass Polyopisthocotylea are known from ultrastructural and histochemical analyses only. In contrast to other blood- feeding parasites, just few biochemical and molecular analyses have been done on digestive enzymes in monogeneans. Therefore, we focused on the biochemical and molecular characterization of hydrolytic enzymes (peptidases) in the hematophagous species Paradiplozoon bliccae and Eudiplozoon nipponicum. The presence of the cysteine class peptidases, mainly cathepsin L, in excretory- secretory products and soluble protein extracts of P. bliccae and E. nipponicum we found. Detection was carried out using fluorogenic substrates, specific inhibitors and the labelled probe DCG-04. On the gels / membranes after electrophoresis / blotting we detected bands of approximately size of 35 kDa in the case of both species and 24 kDa for E. nipponicum. Soluble protein extracts of worms were separated by 2D gel electrophoresis and relevant spots around 35 kDa (P. bliccae) and around 25 ˗ 35 kDa (E. nipponicum) were confirmed by mass spectrometry as cathepsins L. Using degenerate primers based on the conserved motifs of cysteine class peptidases, a partial sequence of cathepsin L gene from E. nipponicum was obtained. Furthermore, 3'RACE PCR method...

No. of bitstreams: 1 PDF - Noiana de Paula Noia.pdf: 1156392 bytes, checksum: a6a9764178b9ec1cd59f8dadd9cb363e (MD5) Previous issue date: 2013-12-16 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The Aedes genus is of great epidemiological importance, highlighting the Aedes aegypti Linnaeus, 1762 and Aedes albopictus Skuse, 1894, the main vectors of dengue, yellow fever and other arboviruses. How are spread across the planet, have become a public health risk factors. Aimed to evaluate the effects of temperature on competition and in the life cycle, and the source of blood meal in fecundity and longevity of females of A. aegypti and A. albopictus. The collections of eggs were performed using traps ovitraps type. The experiments were performed at the Laboratory of Entomology, University of Paraíba State - UEPB in Campina Grande, PB. Competition between A. aegypti and A. albopictus was examined at temperatures of 20, 24, 28, 32 and 36 ° C in the proportion of 10:0, 7:3, 5:5, 3:7 and 10:0 (A. aegypti : A. albopictus). The cycle life was examined at the same temperatures. Feeding two treatments with each meal in quail and the other in swiss mice were used. For all experiments we used 12h light and 70% humidity. In interspecific relationship, there was overlap of A. aegypti on A. albopictus from the first generation (F1), independent of temperature and the proportion of species. The long life cycle did not differ significantly among species independent of temperature, but decreased with increasing temperature. The base temperature (Tb) and thermal constant (K) and hence the number of generations was greater for A. albopictus than for A. aegypti. The repast in mice resulted in greater number of eggs and female longevity for both A. aegypti as for A. albopictus. The substrate used for biting that was more appropriate for the two species, the mouse was, since we obtained the highest female fertility and longevity. The temperature and the substrate used for blood feeding interfere with competition, development, longevity and fecundity of the species studied. The number of generations of insects in the laboratory is higher for A. albopictus than for A. aegypti. / O grande importância epidemiológica, destacando o Aedes aegypti Linnaeus, 1762 e Aedes albopictus Skuse, 1894, principais vetores da dengue, febre amarela e outras arboviroses. Como estão distribuídos por todo o planeta, se tornaram fatores de risco à saúde pública. Objetivou-se avaliar os efeitos da temperatura na competição e no ciclo de vida, e da fonte de repasto sanguíneo na fecundidade e longevidade de fêmeas de A. aegypti e A. albopictus. As coletas dos ovos foram realizadas utilizando armadilhas do tipo ovitraps. Os experimentos foram realizados no Laboratório de Entomologia da Universidade Estadual da Paraíba – UEPB, em Campina Grande, PB. A competição entre A. aegypti e A. albopictus foi analisada nas temperaturas de 20, 24, 28, 32 e 36ºC nas proporções de 10:0, 7:3, 5:5, 3:7 e 10:0 (A. aegypti: A. albopictus). O ciclo de vida foi analisado nas mesmas temperaturas. Para nutrição foram utilizados dois tratamentos um com o repasto em codorna e o outro em camundongo swiss. Para todos os experimento utilizou-se fotofase de 12h e umidade de 70%. Na relação interespecífica, constatou-se a sobreposição de A. aegypti sobre A. albopictus a partir da primeira geração (F1), independente da temperatura e da proporção das espécies. O tempo do ciclo de vida não diferiu significativamente entre as espécies, independente da temperatura, porem diminuiu em função do aumento da temperatura. A temperatura base (Tb) e a constante térmica (K) e consequentemente o número de gerações anuais foi maior para A. albopictus do que para A. aegypti. O repasto em camundongos resultou em maior número de ovos e longevidade das fêmeas tanto para A. aegypti como para A. albopictus. O substrato utilizado para hematofagia que se mostrou mais adequado para as duas espécies, foi o camundongo, visto que obteve-se a maior fertilidade e longevidade da fêmea. A temperatura e o substrato utilizado para o repasto sanguíneo interferem na competição, desenvolvimento, longevidade e fecundidade das espécies estudadas. O número de gerações anuais dos insetos em laboratório é maior para A. albopictus do que para A. aegypti.
