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.

    I’d genuinely appreciate it.

  25. You’re so interesting! I do not suppose I
    have read through a single thing like that before.

    So great to find another person with original thoughts on this subject.
    Seriously.. many thanks for starting this up. This web site is one thing that’s needed on the internet, someone with
    some originality!

    blog that’s both equally educative and interesting, and let me tell you,
    you have hit the nail on the head. The problem is an issue that not enough folks are speaking intelligently about.
    I am very happy I found this during my hunt for something regarding this.

  57. Когда требуется нарколог на дом, обычно речь идёт не о «консультации на будущее», а о ситуации, которая уже мешает жить здесь и сейчас: затяжной запой, тяжёлая абстиненция, сильная тревога и бессонница, тремор, скачки давления, рвота, выраженная слабость, паника или состояние, при котором человек не готов ехать в клинику. В Пушкино выездная помощь востребована ещё и потому, что многим важно сохранить приватность и не вовлекать лишних людей: дома проще согласиться на осмотр, не тратить силы на дорогу и избежать стрессовой смены обстановки. В наркологической клинике «Стабильный Выбор» выезд врача строится по принципу «быстро, но безопасно»: сначала оценка состояния и рисков, затем индивидуальная тактика стабилизации и понятный план на ближайшие часы и сутки.

  59. Отдельная причина, по которой люди тянут до последнего, — страх огласки и лишних последствий. В небольших городах это особенно чувствуется: «все друг друга знают», страшно, что увидят знакомые, начнутся разговоры. Из-за этого человек часто выбирает опасный компромисс: продолжает пить «чтобы не ломало», смешивает алкоголь со снотворными или успокоительными, пытается пережить бессонные ночи и панические качели. Но зависимость не ждёт, пока станет удобно. Поэтому важно, чтобы клиника могла организовать помощь быстро и без лишнего стресса, при этом сохраняя медицинскую точность и безопасность.

  68. Hey fantastic website! Does running a blog similar to this require a large
    amount of work? I have virtually no knowledge of coding however
    I had been hoping to start my own blog soon. Anyways, if you have any
    suggestions or tips for new blog owners please
    share. I understand this is off topic but I just had to ask.
    Appreciate it!

  123. Зависимость редко начинается как «всё плохо». Чаще это выглядит как способ справиться с напряжением: расслабиться после тяжёлого дня, быстрее уснуть, пережить стресс или конфликт. Постепенно употребление становится регулярным, дозы растут, а трезвость даётся всё тяжелее. При попытке остановиться появляются бессонница, тревога, внутренний тремор, потливость, тошнота, скачки давления, раздражительность. В этот момент человек пьёт уже не ради удовольствия, а чтобы не столкнуться с ухудшением. Наркологическая клиника в Клину нужна, чтобы перевести ситуацию в понятный медицинский процесс: сначала оценка состояния и рисков, затем безопасная стабилизация, после — лечение зависимости и профилактика повторения.

  188. Для жителей Воронежа выезд нарколога на дом — это быстрый и удобный способ получить экстренную помощь. Когда человек переживает запой, а его физическое и эмоциональное состояние быстро ухудшается, наркологическая помощь на дому становится оптимальным решением. Врач приезжает и немедленно оценивает состояние пациента: проверяет его пульс, давление, частоту дыхания, уровень сознания и другие важные показатели. Это помогает составить точный план лечения, который будет направлен на восстановление организма, снятие токсинов и стабилизацию состояния пациента.
