Come si trasmette la toxoplasmosi

di
gatto

La toxoplasmosi è una malattia causata da un protozoo parassita, il Toxoplasma gondii. E’ un parassita molto comune nel mondo, ed in alcuni paesi la toxoplasmosi raggiunge percentuali di contagio elevatissime, soprattutto nei climi caldi ed umidi. In molti casi il sistema immunitario è in grado di neutralizzare la presenza del parassita, che quindi resta nel corpo ma non procura danni. Ma ci sono alcune categorie a rischio, in particolare le donne in gravidanza e le persone immunodepresse.

Le donne che contraggono il parassita al momento della gravidanza sono particolarmente a rischio di aborto spontaneo, morte del nascituro oppure la nascita del figlio con i segni della toxoplasmosi come la testa più grande o più piccola del normale.

Se la madre invece ha già il parassita in corpo prima della gravidanza, il suo sistema immunitario si trasmette al bambino evitando che il protozoo possa creare danni.

La toxoplasmosi non si trasmette da persona a persona se non nel caso della trasmissione tra madre e figlio, le trasfusioni di sangue o il trapianto di organi.

Le principali vie di trasmissione del parassita sono invece:

Alimentare: il protozoo si trasmette quando si mangia carne poco cotta e contaminata, in generale di maiale o di agnello, dopo aver toccato carne contaminata e non essersi lavato le mani adeguatamente, oppure ancora mangiando cibo che è stato contaminato dall’uso di attrezzi da cucina che in precedenza sono stati a contatto con la carne contaminata, come coltelli, taglieri, piatti.

Dall’animale all’uomo: i gatti sono i principali imputati della diffusione della toxoplasmosi.

Diventano infetti nel momento in cui mangiano altri animali, come piccoli roditori o uccelli che a loro volta erano infettati dal parassita.

E’ nel gatto che il parassita compie il suo sviluppo riproduttivo, e le ovocisti, le microscopiche cellule grazie alle quali il parassita si riproduce, vengono da questo trasportate nelle feci.

Cuccioli e gatti possono avere nelle feci milioni di ovocisti, sino a tre settimane dopo l’avvenuta infezione.
Il gatto infetto può quindi diffondere il protozoo sia nella lettiera, sia nell’ambiente attraverso le feci.

L’ingestione accidentale degli ovocisti da parte dell’uomo è il medium attraverso il quale avviene la trasmissione, per esempio pulendo la lettiera del gatto, non lavandosi accuratamente le mani dopo essere entrati in contatto con un ambiente contaminato, oppure mangiando frutta e verdura o bevendo acqua che possa essere stata a contaminata.

Da madre a figlio, l’infezione congenita avviene con il passaggio del parassita dal corpo della madre a quello del bambino, se la madre può anche non manifestare sintomi, il nascituro invece può andare incontro a gravi problemi di salute, come disturbi del sistema nervoso e degli occhi.

Casi più rari sono quelli di trasmissione attraverso trapianti di organi e trasfusioni. Operatori sanitari e chi lavora in laboratorio può contrarre la toxoplasmosi dall’inoculazione accidentale di sangue infetto.

  2. Hello just wanted to give you a quick heads up. The text in your post seem to be running off the screen in Internet explorer.

    I’m not sure if this is a formatting issue or something to do with web browser compatibility
    but I thought I’d post to let you know. The design look
    great though! Hope you get the problem resolved soon.
    Cheers

  7. Upon reflection, I actually felt your post was timely and relevant.
    Thank you exceedingly for writing this article; if More
    authors wrote intelligent and time-worthy prose, I gander we’d all understand life better.
    I, personally, think we might place our attention more on staying fit and eating well and free from being perpetually on the computer or cell phone
    screen. Go outside!! (and not being glued to the cell
    phone all the while, either) and living a life in full appreciation of the
    natural world, keeps people feeling sane and feeling joyous.
    Thinking about key subjects is likewise an experience that can assist us to make the discovery of self understanding.

    look into a spinogambino before depositing real
    money simply in order to ensure the spinogambino is active.
