Article Synopsis
- Despite various methods available for detecting Cryptosporidium and Isospora belli in fecal samples, there are concerns about their accuracy in practice.
- The study analyzed 27 positive stool samples for Cryptosporidium and 15 for I. belli using two concentration methods and three staining techniques, finding no major differences in detecting Cryptosporidium but significantly better detection of I. belli using centrifugation.
- The results highlight that different methods have specific strengths and weaknesses, and the detection of these intestinal parasites can vary significantly depending on the concentration and staining techniques used.
To compare the efficacy of stool examination for the detection of Strongyloides stercoralis and hookworm, a total of 634 stool samples from the routine laboratory service of the Pharmacia Faculty, Federal University of Bahia, Brazil, were examined by agar plate culture (APC), Baermann-Moraes and spontaneous sedimentation. The sensitivity of agar plate culture, calculated by combining results of all 3 methods, was 95% for S. stercoralis and 77.

Patients with systemic lupus erythematosus (SLE) as well as carriers of infectious diseases such as Kala-azar, syphilis and leptospirosis were studied. Particular interest was given to the presence of clinical complications related to APS.
