Both in the soil samples and in the water samples analyzed, protozoa and helminths potentially parasitic for humans were found. The name “commensal amoebae” was given to the protozoa belonging to the order of Microbiolovia, considered as human non-pathogenic 12Entamoeba coli was excluded, since it was registered separately due to its frequency.

The percentage of intestinal protozoa found in water samples was The protozoan parasite most frequently associated with diarrhoea worldwide is Giardia intestinalis. The objective of the present study was to evaluate the prevalence of intestinal parasites and the degree of association between environmental variables and the intestinal parasites found in the population, in the soil and in the water, in the town of General Mansilla, Province of Buenos Aires, Argentina Don’t already have an Oxford Academic account?

It is, however, unclear how immigration from areas where genotype B predominates could explain the apparent absence of genotype AII from the rural children investigated in the present study. 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.

Elsewhere in Latin America, however, in Cuba Pelayo et al. Journal of Parasitology 88 — Given that most immigrants who settled in Argentina during the 19th and 20th Centuries were European and most giardial infections found in Europeans are now of genotype B, it is perhaps not surprising that genotype B is now so common in Argentina.

Acta Tropica 10— Intestinal parasite infections produced by protozoa and helminths constitute one of the main worldwide causes of human morbidity and mortality 1.

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

Giardia genotyping All faecal samples found smear-positive for Giardia cysts were processed further, microbbiologia concentrate and clean the cysts and extract their DNA, so that the genotype could be identified Molina et al. In this study we have found deficient sanitary conditions associated with presence of parasites in population and we have evidenced that contaminated soil and water were the source of these parasites.

Blastocystis hominis was the most frequent parasite, followed by Giardia lambliaboth in the CZ and the PZ.

Some of the inhabitants in the CZ have sewer facilities while the rest, like the total population, pour their waste in individual latrines or cesspools, some of them built with a septic chamber.

The transmissible stages eggs, larvae, cysts and oocysts can be found in the environment, either in soil, water or food, as a consequence of direct or indirect contamination with human or animal feces 4,7.

Veterinary Parasitology — The supernatant was discarded and the pellet was observed at light microscopy. You do not currently have access to this article. This observation matches that made earlier, in Argentina, by Minvielle Abstract The protozoan parasite most frequently associated with diarrhoea worldwide is Giardia intestinalis.

The prevalence of parasites was Both Giardia genotypes detected in the present study B and AII were found in each of the three provinces under study Fig. The environmental conditions of the population are detailed in Table 2. Other environmental and socio—cultural conditions had no apparent effect on the infecting genotype of Giardia.

A positive correlation between the presence of “commensal amoebae” in soil samples and human feces was demonstrated, as well as between “commensal amoebae” and E.
