PREVALENCE OF INTESTINAL PARASITES IN child day care centers: EPIDEMIOLOGICAL SIGNIFICANCE

摘要

Intestinal parasites are among the most commonly found pathogens in humans and are?considered a public health problem. The frequency of intestinal parasites was evaluated in?children and staff at two day care centers in the city of Ituiutaba, Brazil and health encouragementactivities were developed. For parasite detection in stool samples the Ritchie’s technique and?the Hoffman-Pons-Janer, Baermann-Moraes, Willis and Ziehl-Neelsen methods were applied.Of 140 children, 88 (62.9%) were positive, where Giardia intestinalis cysts were present in 65?children (51.1%), Entamoeba coli in 22 (17.3%), Endolimax nana in 12 (9.4%), Entamoeba?histolytica/E. dispar in 9 (7%), Hymenolepis nana eggs were found in 5 (4%), hookworms in?4 (3.1%), Ascaris lumbricoides and Enterobius vermicularis in 3 (2.3%) and Strongyloides?stercoralis, Trichuris trichiura, Cryptosporidium spp. and Iodamoeba butschlii in one child?(0.8%). Among the 41 employees examined, 10 (24.3%) were positive, E. coli cysts were?found in 6 samples (35.2%) and E. nana in 5 (29.4%), followed by E. histolytica/E. disparin 4 (23.6%) and G. intestinalis and E. vermicularis eggs in (5.9%). The data show the high?frequency of intestinal parasites in fecal samples analyzed and demonstrate the importance of?adopting preventive measures such as health and education involving the community.
