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.

  91. Hi, Neat post. There is a problem together with your web site in internet explorer, may check this?
    IE nonetheless is the marketplace leader and a huge component to other folks will pass over your magnificent writing due
    to this problem.

  102. I do accept as true with all of the concepts you have offered for your post.
    They’re very convincing and will certainly work. Nonetheless,
    the posts are too quick for starters. Could you please prolong them a little
    from subsequent time? Thanks for the post.

  103. I was suggested this web site by my cousin. I’m not sure whether this post is written by him
    as no one else know such detailed about my problem. You’re incredible!
    Thanks!

  105. Normally I do not learn post on blogs, however I wish to say that this write-up
    very compelled me to take a look at and do it! Your writing taste has been surprised
    me. Thank you, quite nice article.

  108. Here’s a quick share of how Jane ended up using Paybis to
    shift her money from her bank into crypto and then straight into her
    trading account, and honestly, her whole story turned out way
    more unexpected than anyone thought.

    Jane isn’t your regular crypto newbie. Random detail: she collects tiny vintage
    globes and has exactly 27 of them lined up behind her desk.
    Another random thing is that she can solve a Rubik’s
    cube in under 40 seconds. So when she discovered Paybis,
    she approached it with the same energy — fast, efficient, and determined.

    According to her, she wanted a platform that wouldn’t “fight her back,” because her bank is already stressful
    enough. Paybis ended up being perfect: smooth verification, easy deposit, and she
    was able to convert her bank funds into crypto in literally minutes.

    She made a joke that it was easier than ordering sushi.

    Once the crypto hit her wallet, she jumped straight into her trading platform — no delays.
    And because she’s Jane, she turned it into a personal speed-challenge.
    She kept notes on each step, and of course, she made a whole spreadsheet about it.

    Another fun fact: she color-codes everything in her life.

    What surprised her most was how Paybis didn’t overwhelm her with complicated
    menus. She likes things simple — after all, she
    once returned a coffee machine because it had “too many buttons.” So
    the clean process from bank → crypto → trading felt like a
    win.

    She mentioned that anyone wanting to try the same flow should check the link inside this comment,
    but she didn’t want to make a big deal of it.
    Just said it might be helpful.

    In the end, Jane’s whole experience using Paybis was fast, surprisingly fun, and very “Jane-style” — structured, quirky, and full
    of little experiments.

    For anyone interested, she said the link in the comment explains everything a bit deeper, but that’s totally optional.

  113. Thanks for another informative web site. Where else could I get that kind
    of info written in such an ideal way? I’ve a venture that I’m simply now operating
    on, and I’ve been at the look out for such information.

  120. Hello! Quick question that’s totally off topic. Do you know how
    to make your site mobile friendly? My website looks weird when browsing from my iphone4.
    I’m trying to find a template or plugin that might be able to fix this issue.
    If you have any recommendations, please share.

    Thanks!
