taenia Solium Common name:- Pork tapeworm, the armed tapeworm of man. The rostellumresembles convential figure of sun hence name solium.Geographical distribution:-World wide the infection is common amongst those eating raw orinsufficiently cooked "Measly pork".Habitat:- Adult worm lives in upper jejunum of man.Morphology:- Adult worm and egg-Adult worm:-Size-length -2-3ma) The scolex:- 1 mm in diameter. It is globular in outline and has 4 circularsuckers.Head is provided with rostellum, armed with double row ofalternating large and small hooklets.> The rostellar hooklets are shaped like daggers or Arabian poniards.b) Neck:- The neck is short, about 5-10 mm in length.c) Proglottides:- Total no. 800-900▸ A gravid segment measures 12 mm X 6 mm. The common genitalpore is marginal, thick-lipped and is situated near the middle of thelateral margin of each segment, alternately irregular between theright and left margins.>The vaginal opening is not guarded by a muscular sphincter.> The gravid uterus consists of a median longitudinal stem with 5-10compound lateral branches on each side. The gravid segments areexpelled passively in chains of 5-6 at a time and not singly.Life span - 25 years.Eggs:- (same as in T. Saginata)The eggs are infective to pig as well as men.Parasitology (HSC)
Pathogenecity of tapeworm:-Mode of infection:- By ingestion of under cooked meat of the intermediatehost.a) In T. saginata:- Beef containing cysticercus bovis.b) T. Solium - pork containing cysticercus celluloseAs Occasionally they may be responsible for vague abdominalForanddiscomfort, chronic indigestion, anaemia and intestinal disorderssuch as diarrhoea alternating with constipation.1> Adult worm while living in the intestine usually do not give rise toany symptoms.Loreal for>It is possible for the patient to detect the segments of the tapewormin the feaces or on his own body or his clothing.> Larval worm of T. saginata are not found in man but those of Tsolium may occasionally be found.
Diagnosis of Tapeworm infection:-A) By an examination of stool:-➤ At first a naked eye examination of the specimen should be made forsegments.The whitish segments can easily be recognized against dark yellow massof the feaces.B) A microscopical examination of the stool for the eggs of adult worm iscarried out by-a. A direct smear preparation of sample of feaces:-A smear preparation made from the sample after concentrating inone of the low density solutions.A perianal swab (NIH) for the demonstration of eggs, as inenterobiasis may sometimes be helpful in diagnosis of T. saginatainfection.Diagnosis of cysticercosis: Biopsy examination of a subcutaneous nodulecontaining cysticerci.T/t of tapeworn infectiom :- Antihelminthic drugs.Prophylaxis:-1) Individual prophylaxis consists of avoidance of cating raw orundercooked meat of intermediate hosts.2) Adequate meat inspection in slaughterhouse.3) Proper sanitary control of sewage disposal and effective treatment ofinfected individual to prevent infection of the intermediate host.T.
