RIESGO DE CONTRAER ENFERMEDADES PARASITARIAS EN LOS PARQUES PÚBLICOS DE LIMA Y CALLAO
The objective of this paper was to determine the contamination with Toxocara sp. in public parks ofMetropolitan Lima and Callao. Turf samples were collected from 558 out ofthe 1,964 parks existing in Lima and Callao (108, 98, 151and123 from the northern, southern, eastern and western part ofLima and 78 from Callao) during December 1998 and August 199 using the double "W" method. Samples were processed by the flotation method using ClNa saturated solution. A sample was considered positive when presented at least one egg of Toxocara sp. The eggs were incubated and orally inoculated to mice and quails to verify the viability of eggs. Parks were grouped according to the level of conservation as good (well covered with grass), moderate (around 50% covered with grass) and poor conserved (without grass); and according to the social economic level as high, middle-high, middle, middle-low and low. The prevalence rate was 34 ± 9% (mean ± confidence interval), 30±9,41±8, 63 ± 9 and 37±11 % forparks innorthern, southern, · eastern and western part ofLima and Callao, respectively. Contamination level was 73, 49 and 16% in parks with good, moderate and poor level of conservation, whereas according to the social economic level was 73, 62, 47, 29 and 30% in parks with high, middle-high, middle, middle-low and low social economic levels, respectively. Abundant green material and high humidity in good conserved parks would favour conservation of Toxocara sp. eggs. On the other hand, the absence of Toxocara sp. eggs in poorly conserved parks would be dueto direct solar radiation on the eggs. Finally, inoculated mice and quails developed migrant larva, which is indicative of the infective capacity of the eggs.

El objetivo del trabajo fue determinar la contaminación con huevos de Toxocara sp. de los parques públicos de Lima Metropolitana y Callao. Muestras de tierra y césped de 558 de los 1964 parques existentes en los distritos ubicados en Lima Metropolitana y el Callao (108 del cono norte, 98 del cono sur, 151 del cono este, 123 del cono oeste y 78 del Callao) fueron colectadas durante los meses de diciembre de 1998 hasta agosto de 1999, empleando el método de doble "W" y procesadas mediante el método de flotación con solución sobresaturada de ClNa. Los huevos recolectados fueron incubados e inoculadas vía oral a ratones y codornices para verificar la viabilidad a los huevos. Los parques fueron categorizados según su estado de conservación en parques bien conservados (césped en toda su área), medianamente conservados (césped en cerca del 50% del área) y mal conservados (sin césped); y según el estrato socioeconómico de la población circundante en estratos de poder adquisitivo alto, medio alto, medio, medio bajo y bajo. Se encontró una prevalencia de 34±9% (promedio±intervalo de confianza), 30±9%, 41±8%, 63±9% y 37±11%, para los distritos de los conos norte, sur, este, oeste y el Callao, respectivamente. El porcentaje de parques contaminados según el estado de conservación fue de 73, 49 y 16% para parques bien, medianamente y mal conservados, respectivamente, en tanto que según el nivel socioeconómico fue de 73, 62, 47, 29 y 30% para parques de nivel económico alto, medio alto, medio, medio-bajo y bajo, respectivamente. La vegetación y humedad existente en los parques bien conservados favorece la sobrevivencia de los huevos de Toxocara sp, en tanto que su escaso número en los parques mal conservados se debería a su destrucción por los rayos solares. Por último, los huevos larvados que fueron inoculados en ratones y codornices desarrollaron larvas migrantes viscerales indicando su alto grado de patogenicidad. Se concluye que los parques mejor conservados tienden a presentar una mayor presencia de huevos de Toxocara sp. por lo que se deberían realizar campañas de educación sanitaria, desparasitaciones periódicas de las mascotas, reglamentar la circulación de perros en los parques públicos, e incentivar el uso de bolsas plásticas para recolectar las deyecciones de los perros que visiten los parques o implementar letrinas públicas para mascotas.
