Question

What is unique about giardia and trichomonas how are they changing taxonomy?

Answer 1

he taxonomy, life cycle patterns and zoonotic potential of Giardia infecting mammals and birds have been poorly understood and controversial for many years. The development of molecular tools for characterising isolates of Giardia directly from faeces or environmental samples has made an enormous contribution to resolving these issues. It is now clear that the G. duodenalis morphological group is a species complex comprising a series of what appear to be largely host-adapted species, and at least two zoonotic species for which humans are the major host, but which are also capable of infecting other mammals. It is proposed that this new information be reflected in the redesignation of several species of Giardia described previously. The molecular epidemiological tools that are now available need to be applied in different endemic foci of Giardia transmission, as well as in outbreak situations, in order to understand better the frequency of zoonotic transmission as well as to develop more effective approaches to controlling giardiasis.

Answer 2

They lack mitochondria (anaerobic metabolism), lack a golgi apparatus. And possess at least one flagellum for at least part of their life cycle. They live in anoxic environments and some have undulating membranes.

They both are flagellated protozoan parasite.

Trichonomas vaginalis is the causative agent of trichomoniasis and it is sexually transmitted infection of urogenital tract and Giardia lamblia which colonise and reproduces in the small intestine and cause giardiasis and transmission occur through ingestion of dormant microbial cyst in contaminated water or food, or by the fecal-oral route.
