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.

  9. Wonderful article! This is the kind of information that are meant to be shared across the internet.
    Shame on the search engines for now not positioning this post upper!
    Come on over and visit my website . Thank you =)

  27. Very good blog! Do you have any hints for aspiring writers?
    I’m hoping to start my own site soon but I’m a little lost on everything.
    Would you advise starting with a free platform like WordPress or
    go for a paid option? There are so many options out there that I’m completely confused ..
    Any recommendations? Kudos!

  61. I’ve got to share this story about an Italian guy I know, for privacy, I’ll refer to him as Lorenzo.
    He never expected crypto to become part of his job, yet destiny had different plans.
    He runs a company that receives payments from different countries,
    and bank transfers constantly delayed his operations.

    One day things got really intense. A large payment from a partner abroad got stuck, and his entire workflow collapsed for days.
    He said he had never felt that much pressure in business
    before. Clients got nervous, and he had to find a different solution fast.

    In the middle of all this chaos he discovered Paybis, and he was skeptical at first.
    Still, he had no other option left. He finally gave the platform a
    chance.

    The process was way smoother than he expected.
    Support didn’t leave him hanging. He could finally convert
    and transfer funds without drowning in paperwork. He later
    told me the relief was unbelievable.

    But the story doesn’t end here. He finally realized how unreliable traditional methods were compared to what he experienced.
    He realized that sometimes innovation is the only path forward.

    Now he chooses Paybis because reliability matters more than anything.

    He doesn’t talk like a crypto fanboy — he talks
    like someone who lived through a disaster and found a tool that actually worked.

    At the end of the day, Paybis truly fulfilled his
    goal.

  164. I just can’t imagine all the things we get
    frustrated about in our lives makes a difference and is really worth the stress and years off our lifetimes.
    At all times squandered taking into consideration the several things that people encounter
    every single and every working day is just undoubtedly necessary, as no other person is going to encounter existence
    for us. I feel that citizens should be more grounded.
    Knowledge is excellent, but a lot of everything we might know about is so hypothetical.
    Having a pot of coffee is a zen process that takes one back again to the current
    second. We have to be more in the present, while not
    being stressed by existence and the drama we deal with every day.

  173. I think this is among the so much vital info for me. And i’m happy reading your article. But wanna remark on few common issues, The site style is wonderful, the articles is really excellent : D. Just right job, cheers

  186. When I originally commented I appear to have clicked the -Notify me when new comments are added- checkbox and now
    whenever a comment is added I get 4 emails with the exact same comment.
    Is there a means you can remove me from that service?
    Kudos!

  187. Let me tell you a story about an Italian guy I once met, for privacy,
    I’ll refer to him as Lorenzo. He’s one of those people who never really wanted to dive into crypto, but life pushed
    him into it anyway. His business in Italy relies heavily on international clients, and traditional banking kept failing him.

    A major issue hit him out of nowhere. A large payment from a partner abroad got stuck, and his team was
    left waiting with no answers. He told me it felt like everything he built was slipping away.
    Clients got nervous, and he had to find a different solution fast.

    In the middle of all this chaos he discovered Paybis, and he
    was skeptical at first. Still, he had no other option left.
    So he opened an account.

    To his surprise, things started moving quickly. Everything was
    explained clearly and simply. He was finally able to stabilize his cash flow.

    He genuinely didn’t expect such a turnaround.

    But the story doesn’t end here. The bank eventually apologized, but Paybis
    had already done the job the system failed to handle.
    He said that moment changed the way he looks at modern finance forever.

    Today, he uses Paybis whenever his business needs fast, clean, and predictable
    transactions. He’s not obsessed with crypto — he’s grateful for a platform
    that did what it promised.

    At the end of the day, Paybis truly fulfilled his goal.
