Evolução dos esporocistos de Schistosoma mansoni Sambon, 1907 em Biomphalaria glabrata (Say, 1818) e Biomphalaria tenagophila (D'Orbigny, 1835)

Abstract: Estudou-se a evolução dos esporocistos de Shistosoma mansoni das linhagens BH e SJ respectivamente em Biomphalaria glabrata e Biomphalaria tenagophila. Utilizando-se cortes histológicos foram avaliados o aspecto e número de esporocistos primários desde a primeira até a oitava semana de infecção, a contar do dia em que cada molusco foi exposto a 100 miracídios. No decorrer da primeira semana constataram-se diferenças significativas entre as linhagens estudadas quanto ao número e aspecto dos esporocistos primári… Show more

“…Guaraldo et al (1981) in B. tenagophila, Maldonado and Acosta-Matienzo (1947) and Olivier and Mao (1949) in B. glabrata also observed larvae with degenerative processes at greater frequency in the anterior area of the body of mollusks. Guaraldo et al (1981) also observed, with more than 49 days of infection, cellular reactions in sporocysts I and also in sporocysts II, in the location occupied by the same sporocysts I that originated sporocysts II.…”

“…The absence of the fibro-muscular deposition in the sporocysts I justifies that these larvae do not move about (Guaraldo et al 1981), with development taking places where the penetration of the miracidia occurred.…”

“…Newton 17 (1952); Kassim e Richards 8 (1979); Guaraldo e col. 7 25: 359-66, 1991. The possible influence of the immune mechanisms of the molluscs on the developmente of the sporocysts and the resultant behavior of the adult worm in the vertebrate host were studied.…”

“…Os valores observados na atração miraxonal, utilizando-se SCW ou B. tenagophila selecionados frente à miracídios selecionados ou não selecionados, foram muito semelhantes, fazendo crer que a seleção genética do molusco, quanto ao caráter susceptibilidade, não só facilita o desenvolvimento das larvas intra-molusco (Guaraldo e col. 5 1991. The attraction of Schistosoma mansoni miracidea by snails genetically selected for susceptibility to infection is considered.…”
