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.

  47. Wow that was odd. I just wrote an very long comment but after I clicked submit my comment didn’t show
    up. Grrrr… well I’m not writing all that over again.
    Regardless, just wanted to say fantastic blog!

  48. Excellent blog you have here but I was curious if you
    knew of any message boards that cover the same topics talked about here?
    I’d really love to be a part of online community where I can get feed-back from other
    knowledgeable people that share the same interest.
    If you have any suggestions, please let me know.
    Thanks a lot!

  59. This is a very informative post about online casinos and betting platforms.
    I especially liked how it explains the importance of choosing a licensed
    site before signing up.

    Many players often ask where they can find reliable gaming platforms with
    fair odds and smooth payouts. From what I’ve seen, checking platforms like vn22vip helps users compare features,
    bonuses, and overall experience.

    Thanks for sharing these insights — they’re helpful for both beginners and
    experienced bettors.

  68. Καλησπέρα στην παρέα, ένιωσα την ανάγκη να επικοινωνήσω μερικές εντυπώσεις από την προσωπική μου πορεία αναφορικά με τον κόσμο του διαδικτυακού
    στοιχήματος. Στοιχηματίζω για μεγάλο διάστημα
    και έχω δει πως η ποιότητα μιας πλατφόρμας φαίνεται
    πάνω από όλα από τον χρόνο απόκρισης των αναλήψεων.
    Πριν λίγο καιρό χρησιμοποίησα το playjonny καζίνο και οφείλω να ομολογήσω ότι εντυπωσιάστηκα
    από την γκάμα των τίτλων. Αποτελεί όντως ένα ποιοτικό play-jonny gr
    για όποιον θέλουν κάτι σταθερό και το
    σημαντικότερο νόμιμο στην ελληνική αγορά.
    Παράλληλα, πιστεύω ότι οι προσφορές loyalty πρέπει να
    είναι πιο απλά για τον καθένα μας, μακριά
    από περίπλοκους περιορισμούς.
    Ένα άλλο ουσιώδες σημείο είναι η εξυπηρέτηση, που στη γλώσσα μας δημιουργεί τεράστια άνεση στην επαφή.
    Θα ήθελα να μάθω, εσείς τι επιλέγετε; Εστιάζετε σε τα μεγάλα τζακπότ είτε
    σας ενδιαφέρει περισσότερο η χαμηλή μεταβλητότητα
    για να μένει περισσότερο
    η διασκέδαση; Ελπίζω ότι
    θα δούμε μια εποικοδομητική συζήτηση στο φόρουμ!
