Enteroparasitosis en dos poblaciones periurbanas de La Plata, Argentina / Intestinal parasitosis in 2 periurban populations at La Plata, Argentina

The prevalence of intestinal parasites was studied in two urban neighborhoods with different socioecnomic conditions in La Plata, Argentina. Age, sex and enviroment factors were considered. One hundred and one hundred one children up to 14 years old were examinated by coproparasitologic analysis. Giardia lamblia was the most frequent species. Overall prevalences (73,0 and 54,4 percent), frequencies of polyparasitism (45,0 and 14,8 percent), and prevalences of helmithic infection (48,0 and 12,7 percent) were highest in the population having significantly inferior sanitary and enviromental conditions. A correlation with age was observed. It is necessary to apply management practices for the control of enteroparasitoses, in accordance with the corresponding characteristics of the enviromental and sociocultural ecosystem

Estudio de las infecciones por enteroparásitos en una comunidad periurbana de la provincia de Buenos Aires en Argentina / Study of enteroparasite infections in a periurban community at Buenos Aires, Argentina

A survey for intestinal parasites was performed on 38 individuals within the urban area of La Plata city (province of Buenos Aires, Argentina). This community is composed of brick-factory workers who also live in the factory premises. An analysis for intestinal parasites was done on fecal samples collected serially and by means of anal swabs and there after preserved in formol solution. At the same time, the ocurrence of the parasites under study as well as that of commensal organisms was investigated in water and soil samples within the factory environs. Information was also obtained from the members of this community as their age, sex, birthplace and recent travels, either abroad or to the interior of Argentina. The prevalence of the pathogens and commensal parasites was 89,5 percent. The frecuency of protozoans and helminths was: G. lamblia 26,3 percent; B. hominis 65,8 percent; A. lumbricoides 7,9 percent; H. nana 2,6 percent; uncinaria sp. 7,9 percent; S. stercoralis 2,6 percent and E. vermicularis 42,1 percent. None of these parasite or commensal organisms were present in the water samples investigated. Four out of 20 soil samples analyzed contained parasitic elements T. canis eggs (one); G. liamblia cysts (two) and A. lumbricoides eggs (one). These results indicated that most important factors causing such a high prevalence of coproparasites were the poor conditions of personal and community hygiene in combination with the frequent travels to the north and the northeast of the country, regions which are endemic parasitic areas. The implementation of programs on health education and communal sanitation would contribute in the control of this health problem
