Ascaris
Ascaris is a genus of parasitic nematode worms known as the "small intestinal roundworms", which is a type of helminth. One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis. Another species, Ascaris suum, typically infects pigs. Parascaris equorum, the equine roundworm, is also commonly called an "Ascarid".
Their eggs are deposited in feces and soil. Plants with the eggs on them infect any organism that consumes them.A. lumbricoides is the largest intestinal roundworm and is the most common helminth infection of humans worldwide. Infestation can cause morbidity by compromising nutritional status, affecting cognitive processes, inducing tissue reactions such as granuloma to larval stages, and by causing intestinal obstruction, which can be fatal.

Au Secours
by: Celine DionDans les journaux
Tous les pays du monde
Semblent en guerre
¨¤ la radio
On en reparle ¨¤ toutes les heures
En disant qu'il n'y a rien ¨¤ faire
(In the papers
All the countries of the world
Seem in war
On the radio
We hear about it hour after hour
Saying that there's nothing to do)
Moi dans cette vie
O¨´ je dois faire ma place au soleil
Le soir j'ai du mal
Seule ¨¤ trouver enfin le sommeil
Et souvent j'ai tr¨¨s peur
(Me in this life
Where I have to make my spot under the sun
The night I have troubles
Alone falling finally asleep
And I'm often very afraid)
Au secours
Il me faut beaucoup d'amour
Pour comprendre ce qui se passe tout autour de moi
Au secours
Dites-moi au moins qu'un jour
Les gens feront la paix entre eux et pour toujours
(Help
I need lots of love
To understand what's happening around me
Help
Tell me that at least someday
People will make peace with each other and for ever)
Plus de distance
Entre les pays du monde
Plus de fronti¨¨res, plus de m¨¦fiance
Plus de douleur
Un seul but dans le coeur
Entre amis, entre fr¨¨res
(No more distance
Between countries of the world
No more borders, no more distrust
No more pain
One single goal in the heart
Between friends, between brothers)
Il me faut beaucoup d'amour
Pour comprendre ce qui se passe tout autour de moi
Au secours
Dites-moi au moins qu'un jour
Les gens feront la paix entre eux et pour toujours
(Help
I need lots of love
To understand what's happening around me
Help
Tell me that at least someday
People will make peace with each other and for ever)
