During 2012-2016, we identified 179 proglottid
samples (161 diphyllobothriids and 18 taeniids) using molecular methods (Table); restriction fragment length polymorphism analysis with PCR-amplified cytochrome c oxidase subunit 1 (cox1) gene fragment (249-bp long corresponding to base pairs 880-1128) was introduced to confirm diphyllobothriid species (18-20) and PCR-amplified cox1 sequencing (145-bp long corresponding to base pairs 641-785) was used for identification of taeniid species (20).
What you may see are tiny pieces of debris that look like grains of rice around your cat's rectum and tail or white, wiggly sacs of eggs called proglottids
on the feces or around the rectal area.
(or segments) have been described as resembling cucumber seeds, pumpkin seeds, or watermelon seeds when moist, and rice grains when dried (Figure 1).
Dipylidium caninum, although infrequently found in infants, may be improperly diagnosed unless proglottids
, or egg packets, are visualized and identified.
solium eggs and proglottids
are consistently diagnosed when present.
B) Gravid proglottid

shedding rate and log-transformed Eimeria spp.
Strobila A complete tapeworm consisting of scolex, neck, and all proglottid
Morphologic differentiation by either scolex or gravid proglottid
of these 2 species is practically impossible (1,3).
Of the 4 adult worm specimens (strobila fragments) available for analysis, the largest fragment was 900 mm long by 7 mm wide with an average proglottid
length of 2.5 mm.
Cysticerci are released, attach to the small intestine by b) a hookless head and grow unto adult worms up to 10 meters long in 3 months, c) Each segment of the worm (proglottid
) has male and female sexual organs and is capable of producing over 1,000 eggs.
In both, live and dead birds, the presence of adults and larvae of third and fourth stage of the nematode Contracaecum pelagicum (Johnston & Mawson, 1942), adult stages of the nematode Cosmocephalus obvelatus (Creplin, 1825), complete specimens and gravid proglottids
(fragments) of the tapeworm Tetrabothrius eudyptidis (Lonnberg, 1896), and adult and juvenile specimens of the trematode Cardiocephaloides physalis (Lutz, 1926), were identified.
