Mycobacterium tuberculosis, the causative agent of tuberculosis, has two distinguishing characteristics: its ability to stain acid-fast and its ability to cause long-term latent infections in humans. Although this distinctive staining characteristic has often been attributed to its lipid-rich cell wall, the specific dye-retaining components were not known. Here we report that targeted deletion ...
The Ziehl–Neelsen (ZN) stain, also known as the acidfast stain, has been reported to be helpful in detection and identification of Schistosoma eggs. In histological sections, Schistosoma mansoni egg shells appear as ZN positive and Schistosoma haematobium shells as ZN negative. The staining target of the responsible ZN component (carbolfuchsin) in the shell is unknown. Because carbolfuchsin is ...
Modified acid fast staining: a better diagnostic tool in chronic diarrhoea due to cryptosporidiosis.
BACKGROUND Cryptosporidium parvum is an emerging pathogen responsible for chronic diarrhoea in children and immuno-compromised individuals, especially AIDS patients. Currently, there is no effective therapeutic strategy for treating cryptosporidiosis, therefore control and supportive treatment of cryptosporidiosis depends upon rapid and accurate diagnosis of this infection. METHODOLOGY A desc...
Neuro-Sweet disease (NSD) is Sweet disease with central nervous system (CNS) involvement. To the best of our knowledge, the present case report is the first to describe NSD complicated by endogenous infection with Mycobacterium tuberculosis. The present case report describes a male patient who developed NSD-induced meningitis, which initially manifested as a fever, headache and neck stiffness. ...
Tuberculosis is a disease of great importance in developing countries, such as India, where it has caused considerable morbidity and mortality. Sputum smear microscopy is the cornerstone in diagnosis of pulmonary tuberculosis, which is usually done using Ziehl–Neelsen (ZN) method (Vasanthakumari et al., 1986; Gupta et al., 2009; Chandrasekaran et al., 1991). The use of ZN Method in remote areas...
