b. Schistosoma Haematobium
It is fluke that infect venules of the bladder.
Appearance of the egg
- It is found in the urine sediment.
- Has pale yellow brown color.
- Large and oval in shape.
- Has characteristic small spine at one end (terminal spine).
- Measure about 145 x 55 μm.
- The egg contains a full-developed miracedium. Sometimes the
miracedium hatch from the egg and can be seen swimming in the
urine. The miracedium swim in the urine by the help of ciliates that
are surrounding it.
High excretion of S. haematobium egg can be seen usual between 10.00
a.m. and 2 p.m. It is also important to remember that even when persons
are highly infected, eggs may not be present in the urine. Therefore that
is important to examine several specimens collected on different days
and examine carefully, that is due to the irregular pattern of egg
excretion.
c. Wuchereria Bancroftie
• It is tissue nematode that invades lymph vessels. It is usually attack
lower limb.
• In chronic bancroftie filariasis, a condition called chyluria can occur
i.e. passing of chyle in the urine. It occurs when the urogenital
lymphatic vessels, which are linked to those, that transport chyle
from the intestine became blocked and rupture.
• Chile consists of lymph and particles of digested fat (soluble in
ether).
• Urine containing chyle appears creamy white. When blood is also
present, the urine appears pinkish-white.
