Come si trasmette la toxoplasmosi

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.

  8. Thank you for highlighting the importance of personalized routines in memory care. Consistency can reduce anxiety and improve engagement. For anyone looking for more resources and support, check out assisted living .

  9. I think the admin of this web site is in fact working hard
    in favor of his site, because here every material is quality based data.

  10. Hi there, just became alert to your blog through Google,
    and found that it’s really informative. I am going to watch out for brussels.
    I’ll be grateful if you continue this in future. Many people will be benefited from your writing.

  13. Vlastně musím říct, i to že vidět tenhle rychlý vývoj v online automatech v rámci ČR je
    fakt zajímavým dojmem. Všiml jsem si, i to že v
    současnosti vlastně už nejde jen o nějaké
    obyčejné sázení, leč zejména o komfort
    i o určitou úroveň grafiky. Osobně si
    myslím je stále nejbezpečnější prověřit si spinmama česká,
    dříve než se do nějakého nového webu skutečně registruje, jelikož uvedená bezpečnost představuje
    prostě stěžejní bod. Zdá se mi, že hodně lidí přehlíží význam regulace a následně se bohužel diví,
    v momentě kdy systém vypadává takovým způsobem, jak by má.

    Navíc sleduji, i to že se česká komunita ukazuje
    být čím dál zkušenější a nenechá si si věšet rozum na hlavu.
    Docela jsem v očekávání, zda nás brzy čeká velký nástup AI prvků,
    nebo spíše jestli setrváme věrní především standardním smartphonům.
    Jaký parametr je pro vaše hraní během výběru
    čerstvého kasina vlastně tou hlavní podmínkou?
    Hoďte vědět, jakým způsobem hodnotíte ostatní
    členové!
