Contaminação ambiental de áreas de lazer e recreação por parasitos de importância médica

ENVIRONMENTAL CONTAMINATION OF LEISURE AND RECREATION AREAS BY PARASITES OF MEDICAL IMPORTANCE

Abstract

Enteroparasitoses represent a public health problem, affecting a large part of the world population. Leisure or recreation areas with sand or can shelter different parasitic forms contaminating humans, animals and the environment. The objective was to evaluate the presence of parasites in stool and soil samples collected in different areas in the municipality of Ituiutaba-MG. 17 squares were visited and a total of 85 stool samples were collected, analyzed by parasitological flotation techniques, formaldehyde-ether and spontaneous sedimentation. Soil samples were collected at 20 locations between squares and clubs, with five samples at each location. The samples were conditioned in bags forming a “pool of the place”, and identified with date and soil temperature, sent for parasitological analysis. Of the total stool samples collected, 23.5% (20/85) were positive, with 68.18% (15/20) presenting evolutionary forms of Ancylostoma caninum and 9.09% of the samples (2/20) presenting eggs. Dipylidium caninum and / or Toxocara spp. regarding the presence of protozoa, 9.09% (2/20) of the samples contained cysts and / or trophozoites from Giardia lamblia and 4.55% (1/20) presented coccidia oocysts. Of the total soil samples collected, 70% (14/20) of the sites were positive for parasitic forms of helminths, with 85.7% (12/14) showing evolutionary forms of A. caninum, 64.3% (9/14) of Toxocara spp., 14.3% (2/14) Strongyloides stercolaris, 7.14% (1/14) D. caninum or Hymenolepis nana or Spirometra mansonoides. The encounter of parasitic forms in these places highlights the need for health promotion actions, putting the concept of Unique Health into practice.
