Correlation between the presence of symptoms and the Giardia duodenalis genotype
(Citations: 26)
Clinical manifestations of Giardia duodenalis infection vary from asymptomatic infection to chronic diarrhoea. We study the correlation between the presence of symptoms
and the G. duodenalis genotype in 108 patients with giardiasis. Patient age ranged from 2 to 72 years old. We found a correlation between assemblage
AII and symptomatic infections, and between assemblage B and asymptomatic infections in the overall patient group and in patients
less than five years of age. Nevertheless, if only patients of more than five years of age were considered, no statistically
significant relationship between assemblage and symptomatic or asymptomatic Giardia infections was found. In these patients, host factors may affect the presence of clinical manifestations more than Giardia assemblage.
