بعض الملاحظات من كتاب سامي الشيخ ركز عليها الدكتور قوي

dipylidium caninum is the dog tape worm

diphyllobotherium latum is the broad tape worm or the fish tape worm

11_ eggs of both Taenia saginata and solium are characterized by radially striated shell

12 bladder worm is the name for larva of Taenia saginata ( the cysticercus bovis ) but the bladder like worm is the name for larva of hymenolepis Nana (cysticercoid )

13_ egg of Taenia saginata is stained by ziehl neelsen stain but egg of Taenia solium is not stained

14 the durg of choice for the Taenia solium is the atebrine ( 10 tablets )

infection by hymenolepis Nana and Enterobius vermicularis

18 the worm that has rosette shape uterus is the diphyllobotherium latum

19 the diagnostic stage of the dipylidium caninum is the egg capsules

21 the worm that associated with pernicious anemia is the diphyllobotherium latum

22 in diphyllobotherium latum the first intermediate host is fresh water crustacean called cyclops or diaptomus harboring the procercoid larva but the second is fresh water fish as salmon harboring the plerocercoid larva

23 the eggs of diphyllobotherium latum are opperculted wit thick sell

24 only calcified cysts are detected by the X Ray but both calcified and uncalcified are detected by C.T and MRI and ultra sound

25 cysticercosis is cused by the cysticercus cellulose (the larva of Taenia solium)

26 hydatid disease or hydatidosis is cused by the hydatid cyst (larva stage of Echinoccocus granulosus)

27 hydatid fluid conain toxins and salts and enzymes

28 the smallest type worm is the Echinoccocus granulosus

29 the itradermal test of Echinoccocus granulosus is called casoni test
