\"Diferen\u00e7a<\/p>\n

\n

Principal diferen\u00e7a<\/h2>\n

As exotoxinas s\u00e3o subst\u00e2ncias t\u00f3xicas secretadas por bact\u00e9rias e liberadas fora da c\u00e9lula. Enquanto as endotoxinas s\u00e3o toxinas bacterianas que consistem em lip\u00eddios encontrados dentro de uma c\u00e9lula.<\/p>\n

O que s\u00e3o exotoxinas?<\/h2>\n

As toxinas que s\u00e3o liberadas extracelularmente \u00e0 medida que o organismo cresce s\u00e3o chamadas de exotoxinas. As exotoxinas podem viajar de um foco de infec\u00e7\u00e3o para uma parte distante do corpo e causar danos. Por exemplo, neurotoxina (toxina botul\u00ednica, toxina tet\u00e2nica), enterotoxina (toxina da c\u00f3lera), citotoxina. Uma exotoxina \u00e9 uma toxina secretada por bact\u00e9rias. Uma exotoxina pode prejudicar o hospedeiro destruindo c\u00e9lulas ou interrompendo o metabolismo celular normal. Eles s\u00e3o muito poderosos e podem causar danos significativos ao hospedeiro. As exotoxinas podem ser secretadas ou, como as endotoxinas, podem ser liberadas durante a lise celular.<\/p>\n

O que s\u00e3o endotoxinas?<\/h2>\n

As endotoxinas s\u00e3o toxinas lipopolissacar\u00eddicas produzidas por bact\u00e9rias Gram Negativas. O nome endotoxina \u00e9 derivado do fato de que essas toxinas geralmente se ligam \u00e0s c\u00e9lulas e s\u00e3o liberadas apenas quando a c\u00e9lula sofre lise. uma toxina est\u00e1vel ao calor associada \u00e0s membranas externas de certas bact\u00e9rias gram-negativas, incluindo as esp\u00e9cies Brucella, Neisseria e Vibrio. As endotoxinas n\u00e3o s\u00e3o secretadas, mas s\u00e3o liberadas apenas quando as c\u00e9lulas se rompem; s\u00e3o menos potentes e menos espec\u00edficas que as exotoxinas; e n\u00e3o formam tox\u00f3ides. Em grandes quantidades produzem choque hemorr\u00e1gico e diarreia grave; quantidades menores causam febre, diminui\u00e7\u00e3o da resist\u00eancia \u00e0 infec\u00e7\u00e3o bacteriana, leucopenia seguida de leucocitose e muitos outros efeitos biol\u00f3gicos.<\/p>\n

Principais diferen\u00e7as<\/h2>\n
    \n
  1. As exotoxinas s\u00e3o geralmente prote\u00ednas l\u00e1beis ao calor secretadas por certas esp\u00e9cies de bact\u00e9rias que se difundem no meio circundante. morte de bact\u00e9rias.<\/li>\n
  2. As exotoxinas s\u00e3o excretadas por organismos, c\u00e9lulas vivas, as endotoxinas s\u00e3o parte integrante da parede celular.<\/li>\n
  3. As exotoxinas s\u00e3o encontradas em bact\u00e9rias Gram positivas e Gram negativas. As endotoxinas s\u00e3o encontradas principalmente em bact\u00e9rias gram-negativas.<\/li>\n
  4. As exotoxinas s\u00e3o detectadas por muitos testes (neutraliza\u00e7\u00e3o, precipita\u00e7\u00e3o, etc. As endotoxinas s\u00e3o detectadas pelo ensaio do lisado de Limulus).<\/li>\n
  5. As exotoxinas n\u00e3o t\u00eam atividade enzim\u00e1tica em compara\u00e7\u00e3o com as endotoxinas.<\/li>\n
  6. As exotoxinas podem ser filtradas em compara\u00e7\u00e3o com as endotoxinas.<\/li>\n
  7. As exotoxinas s\u00e3o altamente antig\u00eanicas. As endotoxinas s\u00e3o fracamente imunog\u00eanicas.<\/li>\n
  8. Exotoxinas de composi\u00e7\u00e3o qu\u00edmica: prote\u00edna, Endotoxinas de composi\u00e7\u00e3o qu\u00edmica.<\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
