Is Giardia Gram Negative

It has a broad spectrum of antimicrobial activity, including gram positive and gram negative aerobic bacteria. In Giardia, the drug is reduced and activated in the trophozoite, possibly via NADH oxidase. The toxicity of the metabolites is mediated via DNA binding and destruction.

What cell type is Giardia?

Giardia lamblia belongs to the earliest diverging eukaryotic lineage known [1]. Although it is a true eukaryotic cell, it displays several ‘prokaryotic properties’, e.g. lack of mitochondria and peroxisomes, prokaryotic-size SSU rRNA and bacterial-like metabolic enzymes [1,2].

Is protozoa Gram positive or negative?

Despite the fact that Gram-negative bacteria and parasitic protozoa are phylogenetically distant organisms, they express glycoconjugates, namely bacterial LPS and protozoan GPI-anchored glycolipids, which share many structural and functional similarities.
