F. TAENIASIS F.1 Taenia Solium This worm lives in the human intestinal cavity. Eggs are excreted with feces. Sometimes, under certain conditions, the proglottids can exit through the anus. To find out the species that is infecting the patient can only be done by examining the proglottid or scolex, but because the scolex is small, difficult to find, and is only removed from the intestine after treatment, species identification is mostly done by examining the GRAVID proglottid. While scolex examination is used to determine the success of treatment.The infective forms for humans are cysticercus cellulose and eggs. If humans are infected by cellulose cysticercosis found in pork, they will suffer from taeniasis solium, whereas if for various reasons they are infected by eggs they will suffer from cellulose cysticercosis. Egg - Egg Taenia solium And T. saginata difficult to differentiate. - Rounded shape, measuring 30 – 43 x 29 – 38 µ; egg wall (embryophore)consists of hyaline with radial stripes; contains an oncosphere (hexacan embryo) which has 3 pairs of small hooks ('hooklets'). Adult Worms: - Adult worms, 2 – 4 m long, can reach 7 m - Globular scolex, diameter ± 1 mm, equipped with 4 sucking vanes ('suckers'), The rostellum is equipped with 2 rows of hooks and consists of large and small hooks. - Short neck, width ± ½ the diameter of the head (scolex), the posterior part is an area of proliferation and is connected to a series of immature, mature and gravid proglottids (strobila). - Immature segments (proglottids) are short, the genitals are not yet perfect. - The mature segment is almost square, the genitals are fully developed, the comedial cirrh sac exceeds the lateral/longitudinal excretory duct, the uterus is like a club, two ovaries (bilobi) plus one small lobe so it can be called a trilobi. - Long gravid segment, similar to a rectangle. - The uterus is like a stem, each side has 7 – 12 lateral branches (average9), full of eggs; if found in fresh, non-motile feces. - The total number of segments is less than 1000. F.2 Taenia Saginata LikeT. solium, this worm also lives in the human intestinal cavity. Eggs are excreted with feces. The proglottids of this worm can move actively so they often exit through the anus. Proglottid examination is necessary if species identification is desired. LikeT. solium, scolex examination is used to determine the success of treatment. Adult Worms: - Adult worms are 3.5 – 4.5 m long, can reach 25 m, strobila consists of up to 2000 proglottids (segments). - Piriform scolex, diameter 1.5 – 2 mm, equipped with 4 sucking vanes, has no rostellum, the terminal part is a pigmented disc. - Neck, width less than half the diameter of the head, posterior part as an area of proliferation that is directly related to the immature segment - Immature segments are short, genitals are not yet perfect. - The mature segment is almost square in shape, the comedial cyrus sac does not exceed the lateral/longitudinal excretory duct of the ovary bilobi, the uterus is club-like, the genital porus is monolateral alternating. - Long gravid segment, each side of the uterus has 15 - 30 lateral branches, full of eggs. - If found in new feces the gravid segment can move (motile).
