摘　　要：Objective:To communicate the presence of adult females,rabditoid larvae and eggs of Strongyloides stercoralis(S.stercoralis)in the respiratory secretions obtained by tracheal aspirate from a HIV-negative patient who was suffering from polymyositis,and treated with corticoids and amethopterin and assisted by pneumonia.Methods:The respiratory secretions submitted to the Parasitology Laboratory of the Mu(?)iz Hospital were made more concentrated by centrifugation(1 500 r/min for 15 seconds).Wet mount microscopy was performed with the pellet.Results:It revealed adult females,rabditoid larvae and eggs of S.stercoralis.Further parasitological studies performed after the start of the treatment with ivermectin on fresh fecal samples,gastric lavages and tracheal aspirates showed scanty mobile filariform and rabditoid larvae of the same parasite.Conclusions:The presence of adult female S.stercoralis which has never been observed before in the clinical samples submitted to our Laboratory for investigation can be considered as an indirect marker of the severe immunosupression of the patient.Objective:To communicate the presence of adult females,rabditoid larvae and eggs of Strongyloides stercoralis(S.stercoralis)in the respiratory secretions obtained by tracheal aspirate from a HIV-negative patient who was suffering from polymyositis,and treated with corticoids and amethopterin and assisted by pneumonia.Methods:The respiratory secretions submitted to the Parasitology Laboratory of the Mu(?)iz Hospital were made more concentrated by centrifugation(1 500 r/min for 15 seconds).Wet mount microscopy was performed with the pellet.Results:It revealed adult females,rabditoid larvae and eggs of S.stercoralis.Further parasitological studies performed after the start of the treatment with ivermectin on fresh fecal samples,gastric lavages and tracheal aspirates showed scanty mobile filariform and rabditoid larvae of the same parasite.Conclusions:The presence of adult female S.stercoralis which has never been observed before in the clinical samples submitted to our Laboratory for investigation can be considered as an indirect marker of the severe immunosupression of the patient.
