Protostrongylus rufescens: a cytogenetic study.

C Cutillas, D C Guevara, A Valero

    Journal of Helminthology
    |March 1, 1987
    PubMed
    Summary

    The study reveals Protostrongylus rufescens has 2n=11 chromosomes in males and 2n=12 in females, indicating an XO/XX sex determination system. Chromosome behavior during meiosis shows typical configurations and pre-reductional division of sex chromosomes.

    Area of Science:

    • Parasitology
    • Genetics
    • Cell Biology

    Background:

    • Protostrongylus rufescens is an economically significant lungworm.
    • Understanding its genetic makeup is crucial for control strategies.
    • Previous cytogenetic data for this species is limited.

    Purpose of the Study:

    • To determine the diploid chromosome number in Protostrongylus rufescens.
    • To investigate the sex determination mechanism.
    • To analyze the behavior of chromosomes during meiosis.

    Main Methods:

    • Karyotyping of Protostrongylus rufescens.
    • Microscopic examination of diakinesis stage during meiosis.
    • Analysis of chromosome configurations and segregation.

    Main Results:

    • The diploid chromosome number is 2n=11 for males and 2n=12 for females.
    • The sex determination mechanism is XO/XX.
    • Bivalents in diakinesis exhibit cross, phi, and lineal configurations.
    • Sex chromosomes undergo pre-reductional division in meiosis I.

    Conclusions:

    • Protostrongylus rufescens exhibits a distinct chromosome number and XO/XX sex determination.
    • Meiotic behavior provides insights into the genetic system of this parasite.
    • This cytogenetic data is foundational for future genetic studies and parasite management.
