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

The protozoa and helminths found are shown in Table 1. Please review our privacy policy. Genotype-B infection in older children might be a consequence of various factors: The potential contamination of the environment depends on several factors, such basualdl the number of infected hosts, number of transmissible stages eliminated into the environment, agricultural practices, contact with animals, activity and behavior of the host, migrations of human populations, social, cultural and ethnical differences of the individuals; drinking water quality, source of food supply, body-waste disposal, home garbage disposal, geographical distribution, climate and hydrogeology of the area 2,4,9.

We evaluate the prevalence of intestinal parasites in people and the degree of association between environmental variables and parasites found in population, soil and water in a rural area of Argentina during In CZ there were households and in PZ there were Future research to expand our knowledge on the relationships between Giardia genotype and symptoms in children should include studies on larger groups of children with symptomatic and asymptomatic infection and on children from other regions of Argentina.

The prevalence of intestinal parasites in the studied population was Similar values to those found in this study were reported in Chile 11 and, in Argentina, two studies report Despite the geographical differences, the predominant genotype in the present study was the same in each study province, perhaps indicating that historical immigration and other mass movements of humans Ponce—Macotela et al.


The environmental conditions of the population are detailed in Table 2. The fact that the three attended the same school may indicate that they were exposed to the same source of infection. 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.

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, Sign In Forgot password? Your comment will be reviewed and published at the journal’s discretion. Diarrhoea was not, however, found to be significantly associated with genotype-AII or genotype-B infection.

Other studies have reported a significant association between genotype A and the presence of symptoms Read et al. The protozoan parasite that causes most cases of diarrhoea worldwide is Giardia intestinalis G.

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

Therefore, 35 CZ and 25 PZ samples had to be taken. Household setting rural v. Odds ratios ORS were calculated for statistically significant associations.

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, slime and clay. The main aims of the present study were to identify the genotypes of G. To select the individuals, the following criteria were taken into account: Both Giardia genotypes detected in the present study B and AII were found in each baskaldo the three provinces under study Fig.


As regards garbage disposal, house collection predominated in the CZ, unlike in the rural population, where burning was mictobiologia most frequent way of disposal.

Pet—human transmission of any genotype may also be important in Argentina and merits further investigation. They also want to acknowledge Translator Laura Cipolla for her translation of the manuscript.

According to the municipal census ofthe people inhabit in a central zone CZ with a population micrrobiologia of 20 inhabitants per square km and in the peripheral zone PZ with six inhabitants per square km. Microbiologi 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 This article is also microbillogia for rental through DeepDyve.

Parasite Immunology 28 — There was a statistically significant association between genotype-B infection and abdominal pain. The study area was the rural town of General Mansilla, located at 96 km from the City of Buenos Aires. Buenos Aires province, in central—eastern Argentina, has a humid and moderate climate, with a mean annual rainfall of mm.
