Abstract The karyotype of glirid tapeworm Rodentolepismyoxi (Rudolphi, 1819) (Cestoda: Hymenolepididae) comprises six pairs of small bi-armed chromosomes (2n = 12). All pairs of chromosomes possess uniform morphology, i.e. metacentric, submetacentric or meta-submetacentric types of structures. The formula of the karyotype structure is n = 2m + 1m-sm + 3sm. The absolute chromosome length ranges from 3.78 to 2.00 μm. The mean total length of the haploid complement is 15.98 μm. The first pair… 

Cytogenetics and chromosomes of tapeworms (Platyhelminthes, Cestoda).

The chromosomes of Rodentolepis nana (Siebold, 1852) Spasskii, 1954 obtained from naturally infected mice conventionally maintained in a Braziuan laboratory animal house.

The studied species differed in chromosome morphology when compared to previous description by Mutafova and Gergova (1994) in Bulgaria, suggesting an intraspecific variation.



Karyometrical analysis of Microsomacanthus spasskii and M. spiralibursata

Analysis of Giemsa-stained mitotic metaphase plates of Microsomacanthus spasskii and M. spiralibursata revealed the diploid chromosome numbers for both species to be 2n=6.0 μm, suggesting possible pathways of the karyotypic evolution within the family Hymenolepididae.

Mitotic chromosomes of Sphaerostomum bramae (Müller, 1776) Szidat, 1944

Close karyological affinity was noted between S. bramae, the representative of the family Opecoelidae, and other karyologically studied species of some families in the order PlagIORchiiformes: Troglotrematidae, Plagiorchiidae, Prosthogonimidae, Lecithodendriidae and Telorchiidae.

Karyotypes and chromosome morphologies of Megalodiscus temperatus and Philophthalmus gralli

Abstract The karyotypes of two hermaphroditic trematodes, Megalodiscus temperatus and Philophthalmus gralli, were described and compared as to chromosomal morphology and constitutive heterochromatin

Keys to the cestode parasites of vertebrates.

This book provides keys to enable specialists and non-specialists to identify cestodes to generic level and is a standard work on tapeworm identification and will be indispensable for parasitologists.


The karyotype of Hymenolepis citelli (McLeod, 1933) has been studied using early cleavage embryos isolated from 9-day-old worms that had been pretreated for 4 h at 37.5 °C in culture medium

“Animal Cytology and Evolution”

WE were surprised at the content, and still more at the tone, of the review by Prof. C. D. Darlington of M. J. D. White's “Animal Cytology and Evolution”1. In our opinion, it would be unfortunate if

Cytological studies on three hymenolepidid species

The examined species differed in the morphology of some chromosomes in the karyotypes and had one arm which was proved by the terminal localization of the constitutive heterochromatin in Vampirolepis erinacei.
