Abstract
Giardia intestinalis is a parasite of worldwide distribution, causing acute non-bacterial diarrhea. Parasite transmission is fecal-oral and it can get between humans, humans-animals and animals-animals, being waterborne transmission main, so it is generally considered that this disease is an important health problem.. This protozoan parasite has a high genetic variability, because it has a diverse range of host. This protozoan has eight genotypes identified, with a host-specific relationship; but some of them could be non-specific, which allows zoonotic transmission. There are some techniques conventionally used for the diagnosis of infection with G. intestinalis, however these have low sensitivity due to intermittent elimination of cysts; but to investigate this area, many new techniques are available, such as Polymerase Chain Reaction(PCR), Restriction fragment lenght polymorphism (RFLP), Sequencing. It’s not clear the role of pets in zoonotic transmission, genotype distribution in our environment and impact in health population. The aim of this paper is showing particular characteristics of G. intestinalis, health problems that this parasite represent to population, the molecular tools available and its potentiality to resolve some questions about this important protozoan.References
