This sum excluded common taxa such as gregarines, ciliates, nematodes, cestodes
and prokaryotic inclusions.
In young birds, heavy infections of cestodes
can result in reduced efficiency and slower growth.
Oochoristica crotalicola, a new anoplocephalid cestode
from California rattlesnakes.
Reduction of egg size in natural populations of threespine stickleback infected with a cestode
, Distoichometra bufonis, and two species of nematodes, Rhabdias ranae and larvae of Physaloptera sp.
We observed six taxa of nematodes, one cestode
, one protozoan, and one mite (Table 2).
Quantitative scores were used for parasites that could be tallied individually, including prokaryotic inclusion bodies, nematodes, and cestodes
bufonis is unknown but Joyeux (1927) regards the life history of nematotaeniid cestodes
to be direct, that is, without an intermediate host; infection of a new host occurs through ingestion of cestode
in the caudal fin; larval cestodes
were relaxed in cold tap water overnight, transferred to 70% ethanol for fixation, stained with acetocarmine, and mounted entire in Canada balsam.
Guide to identification of diphyllobothriid cestodes
were fully invaginated and had a typical deep invagination canal (Fig.
The carriage of larval Echinococcus multilocularis and other cestodes
by the musk rat (Ondatra zibethicus) along the Ourthe River and its tributaries (Belgium).
multilocularis intensity (number of cestodes
per host) ranged from 1 to 1,400 (median 20.
However, with the exception of the blood fluke Schistosoma mekongi, infection with trematodes or cestodes
has seldom been reported (8).
