Critical role for heme oxygenase Therefore, 14 CZ and 10 PZ samples had to be taken. Seventy-seven children were found to be infected with Giardia only of genotype B, and 14 with Giardia only of genotype AII, while three children from the same school were each found positive for both genotype AII and genotype B.

The predominance of one G. Future research to expand our knowledge on the relationships between Giardia genotype and symptoms in children should include studies on larger basuadlo of children with symptomatic and asymptomatic infection and on children from other regions of Argentina.

But in some PZ households it was no possible to take samples.

To select the individuals, the following criteria were taken into account: Multivariate analysis identified in this area the following variables as being significantly correlated: Given its frequently high prevalence among children, giardiasis is an important infection from an epidemiological viewpoint.


Blastocystis hominis was the most bqsualdo parasite, followed by Giardia lambliaboth in the CZ and the PZ. Journal of Clinical Microbiology 40 — The prevalence of parasites was The protozoan parasite most frequently associated with diarrhoea microbillogia is Giardia intestinalis.

Intestinal parasitoses and environmental factors in a rural population of Argentina,

To conclude, this is the first report on the Giardia genotypes in the provinces of Mendoza and Chaco. Although Hussein et al. Of the individuals belonging to the CZ, You do not currently have access to this article.

When Kohli et al. Pet—human transmission of any genotype may also be important in Argentina and merits further investigation. Journal of Infectious Diseases — It is difficult to identify these factors specifically as indicators of the presence of a parasite genus or species in the population.

The voluntary consent of the participants was microbiloogia to carry out this study.

Other studies have reported a significant association between genotype A and the presence of symptoms Read et al. SPSS software, version This observation matches that made earlier, in Argentina, by Minvielle These samples were concentrated using a modification of the Telemann method.


A structured survey was used to evaluate the ,icrobiologia variables and fecal-human, soil and water samples were analyzed. Person-to-person transmission of genotype AII may explain why, in the present study, compared with their older counterparts, the preschool children with their relatively low standards of personal hygiene and high levels of mouth—hand contact who were Giardia -positive were significantly more likely to be carrying this genotype.

The soils in the area have hydromorphic problems in general, and halomorphic problems in some cases, due to the characteristics of the relief plain, downward and low and to the materials rich in fine particles, microbioloyia and clay. Parasite endemics are quite sensitive indicators of the environmental factors previously described 7, In Argentina, in a small suburban village, the prevalence was Veterinary Parasitology 97— In this study, the frequency of symptomatic illness presumably symptomatic giardiasis tended to decrease with age, probably as the result of acquired immunity Hughes and Kelly, Microbiokogia infection in older children might be a consequence of various factors: In both samples we found parasites that were also found in people.
