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.

  111. À mon humble avis, je remarque que le monde des paris
    possède vraiment progressé dernièrement. Un détail qui m’interpelle, reste
    la qualité des actuelles plateformes mobiles, donnant le moyen de parier sans aucun problème quel que soit l’endroit.
    Personnellement, je crois que la fiabilité concernant les paiements
    représente le point le vraiment important, et quand on consulte une
    sérieuse spinogambino avis détaillant le portail actuel,
    tout semble beaucoup plus rassurant. En outre, je suis souvent étonné par la diversité des machines en temps réel qui sortent chaque mois, car ces derniers apportent
    une ambiance incroyable directement. Mais, je me demande : selon vous, quel genre de système de promotion représente réellement le détour afin de débuter sans
    trop prendre de danger ? Il serait utile d’échanger nos méthodes avec tout le monde
    pour que le groupe puissent éviter les soucis classiques, qu’en pensez-vous ?

  138. Z mojego doświadczenia wynika, niedawno sektor e-gamblingu pędzi naprzód zaskakująco sprawnie. Odnotowałem, że sporo użytkowników poszukuje rzetelne platformy, gdzie kluczową rolę gra nie tylko nagroda, ale też dobra zabawa. Czytając liczne opinie, natknąłem się na wyjątkowo obiektywny tekst, którym jest https://classifieds.ocala-news.com/author/louisacarri, jaki pokazuje szereg kluczowych kwestii rozważnego obstawiania. Z mojego punktu widzenia, kluczowa jest zawsze chłodna głowa, ponieważ bez tych zasad szybko roztrwonić umiar w kwestii portfelem. Jestem ciekaw, w jaki sposób wy dobieracie swoje ulubione sloty a także lub czy patrzycie na wskaźnik zwrotu przed zrealizujecie wpłatę? Moim zdaniem dobrze jest wymieniać się takimi wnioskami, żeby wszyscy mogli grać z większym sukcesem oraz rozważnie. A jak tam u was, posiadacie pewne metody na utrzymanie balansu między grą a bezpieczeństwem?
