Question

BlackTom AI · Accepted Answer

The question asks for statements that are true regarding Giardia lamblia, EXCEPT one.
Option a: 'Watery foul smelling diarrhea is presented in Giardiasis' — This is a classic clinical presentation of giardiasis, caused by Giardia lamblia, characterized by foul-smelling, greasy, stools and chronic diarrhea in many cases. This statement is true.
Option b: 'Exhibits falling leaf motility' — Giardia trophozoites are well known for their distinctive 'falling leaf' motility pattern under microscopic observation, due to their flagellar movement. This statement is true.
Option c: 'Multiplies by binary fission' — Giardia reproduces asexually by binary fission, producing two organisms from a single one, which is typical for many protozoa. This statement is true.
Option d: 'Undulating membrane enhances its motility' — The undulating membrane is a structure associated with Giardia, but the primary drivers of its motility are the multiple flagella; the claim that the undulating membrane enhances motility is not a standard or ascribed function for Giardia movement. This statement is not considered true in the typical descriptive anatomy of Giardia motility, making it the EXCEPT.
In summary, options a, b, and c describe accurate clinical or biological features of Giardia lamblia, while option d is the inaccurate statement and is the correct choice for the EXCEPT.
