| comparative study between immunohistochemical grading and giardia genotyping among symptomatic and asymptomatic humans. | in the last years, multiple studies indicated the potential effectiveness of the polymerase chain reaction (pcr) for detection of giardia in pathological specimens. by using the difference at the triose phosphate isomerase (tpi) gene locus, we investigated the genotype groups of giardia lamblia isolated directly from fecal specimens collected from humans living in dakahlia governorate, egypt. immunohistochemical staining for detection of giardia local antigenic and cellular immune-determinants f ... | 2007 | 20306658 |
