TORRES LINDARTE, Giovanny; ZAPATA TAMAYO, Mario; RESTREPO ISAZA, Marcos  and  RIOS OSORIO, Leonardo. Scientific research about genotyping and distribution of Giardia intestinalis in humans and dogs from America. Salud, Barranquilla [online]. 2011, vol.27, n.1, pp.49-62. ISSN 0120-5552.

Objetive: To describe America geographical distribution of A, B, C and D Giardia intestinalis genotypes founded in humans and dogs, and molecular markers and techniques used to detect them, accordingly to scientific literature. Materials and methods: Systematic revision was made it and 19 scientific articles were selected in which Giardia intestinales human isolates were characterized; 10 of this articles reported dog isolates. Results: 31,6% of the studies were made in Mexico. A genotype in 89,5% and B genotype in 52,3% were reported in studies that analyzed human isolates, in front of, A genotype in 60%, B genotype in 20%, C genotype in 30% and D genotype in 20% that were reported in analyzed dog studies. PCR-RFLP was the most used molecular technique, and fi-Giardin gen was the most used molecular marker. Conclusions: A genotype was responsible of both humans and dogs Giardia intestinalis infections in America; and B, C and D genotype were identified in infections, too. Findings of infected dogs with zoonotic genotypes support their role as a potential source for human infection with G. intestinalis.
