AVENDANO, LETICIA et al. Strongyloides stercoralis INFECTION IN ALCOHOLIC PATIENTS. Parasitol. día [online]. 1999, vol.23, n.3-4, pp.91-94. ISSN 0716-0720.  http://dx.doi.org/10.4067/S0716-07201999000300005.

The infection with Strongyloides stercoralis in 106 chronic alcoholic patients W8S evaluated, using agar plate culture (APC),Baermann method, and microscopic observation of direct smear of feces. Baermann method detected 6 (5.7%) cases: whereas by APC one case W8S not diagnosed (sensitivity of 83.3%), and only 2 were visualized by direct smear (sensitivity of 33.3%). Other intestinal parasites diagnosed were Endolimax nana (16%), Giardia 1amblia (7.3), Entamoeba coli (6.6%), Entamoeba histolytica (4.7%), hookworm (0.9%), Hymenolepis nana (0.9%), and Entamoeba hartmanni (0.9%). The overall prevalence of intestinal parasites in the patients studied was 30%. This value is relatively low. but it is in accordance with the national prevalence of 21% or less than 5% if only helminths are considerd. lt is important the comparison of hookworm and S. stercoralis infection in alcoholic patients, since both parasites have similar infection mechanisms, and our data showed a higher prevalence for the latter, that denote possible increasing risk for this infection.
