Parasitological and pathological study for Parasitic cysts in animals and Human of Iraq

Abstract

There are  some  parasitic  cysts  occur  in  animals  and human , one of  the most  important  is  the  hydatid  cysts   .  More  than  thirty  years  hydatidosis  was  followed  in Mosul  , Baghdad ,  Al- Qa-disyia , Babylon and  Najaf  .  Hydatid  Cysts were  collected  from  animals  of  slaughter  houses  of  these  provinces  , while  Human  cases  were  followed  in  surgical  rooms of  main hospitals .  Sheep  hydatidosis  was the  highest  percent  ( 45% )more  than  other  animals , while  the  lowest  was  in buffalo  5% .

Fertile  hydatid cysts  and  sterile  cysts  were  identified  by  eosin  stain , so  the  highest  percent  of  fertile  cysts  were   in  sheep  74%  while  the  lowest   was  in cattle  22% , while  sterile  cysts  were  highest  in  cattle  .Viability of  theprotoscolices were examined by  eosin stain .

Beside hydatid  cysts two  other  cysts were  recorded  depend  on morphologic  and  pathologic   Characterizations  , therefore  hydatid cyst  of  Echinococcusgranulosus was  the  highest  percent   , but  there are other  cysts  were  diagnosed  as Cysticercustenuicollis( Larval  stage  of  Taeniahydatigena )  .  Coenuruscerebralis(Larval  stage  of  Multicepsmulticeps ).
