The karyotype of Mastophorus muris (Gmelin, 1790) comprises four pairs of small autosomal chromosomes and two larger sex X chromosomes in females or one X chromosome in males (2n = 8 + XX/XO). All pairs of chromosomes possess rather uniform morphology without distinct primary or secondary constrictions. No heterochromatin bands were found by C-banding analysis. The absolute chromosome length ranges from 4.02 to 2.24 μm. The mean total length of the haploid complement is 14.34 μm. The course of gametogenesis represents a typical pattern common in the order Spirurida. The recently available karyotypes of spirurid nematodes have been reviewed.
Résumé
Le caryotype de Mastophorus muris (Gmelin, 1790) comprend quatre paires de courts chromosomes autosaumaux et deux chromosomes X chez la femelle, ou un X chez le mâle (2n = 8 + XX/XO). Toutes le paires de chromosomes possèdent à peu près la même morphologie, sans constriction primaire ou secondaire. L'analyse par C-banding n'a pas permis de révéler la présence de bande d'hétérochromatine. La longueur totale du chromosome est comprise entre 4,02 et 2,24 μm. La plus grande longueur totale du chromosome haploïde est de 14,34 μm. Le cycle de la gamétogenèse représente un modèle commun dans l'ordre des Spirurida. Le caryotype d'autres spirurid nématodes a été revu.
