Background: Tuberculosis (TB) is a health problem worldwide. Cutaneous TB comprises a small fraction of all clinical forms of TB. Objective: The purpose of this study was to assess the disease pattern of cutaneous TB in an Asian country. Materials and Methods: Totally, 50 cases of cutaneous TB were diagnosed on histopathology in a tertiary care hospital over a period of 7 years. Relevant clinic...

Due to increasing numbers of patients with documented infections with Cryptosporidium and other coccidia, it is important for the physician and clinical laboratory to be aware of the appropriate diagnostic techniques necessary for organism recovery and identification. Although Cryptosporidium is found in the gastrointestinal tract, tissue biopsies may be insufficient for organism recovery; the ...

Some techniques available at our laboratory were tested for their ability to aid in the morphological diagnosis of hydatid elements (Echinococcus granulosus ["Taenia echinococcus"]) isolated from cysts in humans and sheep. Unstained, methanol-fixed hooklets were fluorescent, most starkly so under violet light (excitation filter wavelength, 405 nm; long-pass filter wavelength, 495 nm). Auramine-...

UNLABELLED The resurgence of Mycobacterium tuberculosis in association with HIV infection has focussed much attention in the rapid diagnosis of high risk cases. Infection with HIV is known to alter the presentation of pulmonary tuberculosis. The present study was under taken to compare the efficacy of fluorochrome stain (Fl) with conventional Ziehl Neelsen (ZN) stain in the diagnosis of pulmona...

Method: Three hundred and twenty-nine patients were included in this study during the period from October 2004 to January 2006. The patients were examined for the presence of acid-fast bacilli. Thin bacterial smears were prepared and stained by Ziehl Neelsen (ZN) stain. Two tubes of the Lowenstein-Jensen (LJ) medium were inoculated with 20 μl of the neutralized sputum sample that was obtained f...
