CHARACTERISTICS: G. lamblia is a flagellated enteric protozoan parasite 1. There are two stages in the lifecycle, a motile vegetative form (trophozoite) which reside in the small intestine and is responsible for disease manifestations and an infective resistant form (cyst) responsible for transmission Giardia lamblia PATOGENIA •A Giardia provoca diarréia e má-absorção intestinal •Adere-se às microvilosidades do intestino delgado através de seu disco ventral suctorial e impede a absorção de nutrientes - tapete •Possui enzimas (proteases) que poderiam agir sobre glicoproteínas de superfície e lesar as microvilosidades •Desencadeia resposta inflamatória e imune com produção de IgA e IgE que ativa mastócitos e libera histamina - edema - aumento de motilidade→ diarréi La mayor parte de los aislamientos de Giardia de ambos genotipos son susceptibles a la infección por los GLV. Sin embargo, no se conoce el papel de estos endosimbiontes en la patogenia de la infección por Giardia.
