Notes
Roman’s Sign cause by American trypanosoma
-Mega syndrome Sign cause by American trypanosoma
-Plasmodium falciparm cause malignant malaria and it’s
commonest in Africa
-Malaria caused by bite of female mosquito anterior
station
-Malaria attack(paroxysm) caused by rupture of schizont
in RBCs and release of merozoites and pigment ,this
occur in erythrocytic cycle
-Relapse of malaria caused by reactivation of
hypnozoites in liver this occur with P.ovale and P.vivax
in pre or exoerythrocytic cycle
-Recrudescence of malaria caused by presence of
dormant parasite in RBCs this occur in P.malariae and
P.falciparum
-Black water fever caused by P.falciparum
Notes
Toxoplasma gondii transmetes by transpaltation
-retroinfection caused by Entrobius vermicularis
-Atrophy of crypt caused by capillaria phillepeniasis
-Trichomonas vaginalis transmited by sexual
intercourse
-alvular hydrates cyst cause esophageal varieces
-hemiplagia causes by paragonimus westermani
-Bile duct carcinoma (cholangiosarcoma) caused by
clonorchis sinesis
Notes
Gardia Lamblia cause atrophy of intestinal villi
-strawberry cervix in Trichomonus vaginalis
-In Leishmania promastigote inter through regurgitation
-In Leishmania infective stage promastigote and
diagnostic stage Amastigote
-Leishmania maxicana maxicana cause chiclero ulcer
-Kala azar is an Indian name , mana is only host
African trypanosoma cause by bite of infectes Glossina
anterior station
-winter buttom’s sign cause by African trypanosoma
-American trypanosoma caused by Bed bug (Reduvid
bug) or Triatoma megistus posterior station
-Chagoma caused by American trypanosoma
Some treatments:
African trypanosoma ttt by suramin
