- Eggs in Medical parasitology.

- when we asked about diagnosis of parasites

we may say that the diagnostic material is eggs

then we must say the characters of eggs

for example :-

Q laboratory diagnosis of fasciola gigantica ?

Answer:- examination of the stool for the characteristic

egg which has the following characters....?....

- when we talk about any egg of helminthes you must

comment on 6 items

4 s ...- size -shell - shape

- special characters

2c ....-content (contain embryo or not)

- sexually transmitted parasites.

1- Trichomonas vaginalis.

- Cause Trichomoniasis.

- T. vaginalis infection is limited in men due to trichomonocidal activity of prostatic secretion and flushing out of the parasites from the urethra during micturition, although it may cause mild urethritis or occasionally prostatitis.

- In women, it is oftenasymptomatic,but if infections persist with vaginitis with frothy vaginal discharge of offensive odour and associated with itching.

2-Human Lice

a-Pediculus humanus.

- Pediculus humanus capitis (head louse),

- Pediculus humanus corporis (body louse) human lice cause : Epidemic typhus , Trench fever, Epidemic relapsing fever and Pediculosis.

b-Phthirus pubis : which causes Pediculosis and Blepharitis .

3-Sarcoptes scabiei : which is the causative parasite of scabies.

- Blood parasites.

- Parasites transmitted through blood transfusion.

= parasites which have apart of its life cycle in the blood

1- Leishmania donovani .

which causes visceral Leishmaniasis either old world or new world

2- Plasmodia species .

3- Babesia species .

4-Toxoplasma gondii .

5-Trypanosoma species :-

a-Trypanosoma brucei complex

-Trypanosoma brucei gambiense .

-Trypanosoma brucei rhodesiense.

b-Trypanosoma cruzi.

==============================

- Transplacental (congenital ) transmitted Parasites.

=1- All transmitted by blood except Babesia species.

2- Ancylostoma duodenale ( rare).
==============================
- Parasites Detected in peripheral blood.

1. Plasmodia species inside RBCs.
2. Babesia species inside RBCs.
3. Leishmania donovani inside WBCs ( macrophage).
4. Toxoplasma gondii inside WBCs ( macrophage).
5. Trypanosoma species Intercellular (between blood cells) .
6. Microfilariae except onchocerca volvulus Intercellular (between blood cells) .

==============================
- Parasites which cause anaemia :-

1. Leishmania donovani ...Aplastic anaemia.
2. Plasmodia species....Haemolytic anaemia.
3. Shistosoma species..iron deficiency anaemia.
4. Hookworms............iron deficiency anaemia.
5. Diphyllobothrium latum...Perniciuos anaemia.
