The study was designed to compare the efficacy of cetylpyridinium chloride (CPC) and sodium chloride (NaCl) decontamination method with N-acetyl L-Cystine (NALC) and sodium hydroxide (NaOH) decontamination (the reference method) method for the recovery of Mycobacterium tuberculosis (MTB) from clinically suspected cases of pulmonary tuberculosis. To evaluate CPC-NaCl and NALC-NaOH decontamination methods, sputum specimens (n = 100) were studied (culturing on Lowenstein-Jensen medium), and the performances were compared. The CPC-NaCl decontamination method demonstrated a sensitivity,...

A total of 500 stool samples were subjected to examination with the help of direct microscopy and concentration methods . Of these, fifty two (10.4%) specimens were positive for Cryptosporidium parvum. Among direct microscopy methods - direct wet mount, negative staining and modified Ziehl - Neelsen staining showed a positivity of 22 (4.4%), 14 (2.8%) and 39 (7.8%) respectively. After the Formol - ether Concentration (FEC) technique, wet mount, negative staining and modified Ziehl - Neelsen stain were positive in 32 (6.4%), 37 ( 7.4%) and 52 (10.4%) cases respectively. Wet mount after...
