Aim: The quality of tuberculosis diagnosis service is indispensable for early infection control and preventing unnecessary anti-tubercular therapy use. TB in Sudan mainly relies on detecting tubercule bacilli using the Ziehl-Neelsen (ZN) staining technique. Thus, current study aimed to compare ZN microscopy with GeneXpert diagnosing pulmonary (PTB) laboratories center Khartoum state, Sudan. Met...

The aim of this study was to compare Fluorescent(auraminO rhodamine,AO)method ,Ziehl-Neelsen (ZN hot method)and kinyoun(cold method) staining techniques for the diagnosis of Mycobacterium tuberculosis. Materials And Methods: 186(on 3 consecutive days) sputum samples were collected from 62 suspected pulmonary tuberculosis patients, processed by petroffs method, and subjected to direct microscopy...

BACKGROUND To report a rare presentation of culture-positive Mycobacterium chelonae corneal ulcer and its management. FINDINGS We report a rare case of a patient with a history of chronic pain and blurriness of vision. Examination revealed a chronic nonhealing paracentral corneal ulcer inferiorly at the 5-7 o'clock meridian with anterior chamber reaction unresponsive to routine antibiotic and...

A 60-year-old woman presented with a painful lump of 4 months duration in her right breast. She denied any history of breast trauma or family history of breast cancer. Physical examination detected a firm, tender mass in the upper inner quadrant of her right breast without an associated sinus tract. Cytology from fine-needle aspiration of the swelling showed epithelioid cells, lymphohistocytic ...

Interstitial pneumonia (2/3 of the lungs were affected) and diffusely enlarged bronchial and mediastinal lymph nodes were diagnosed by gross examination of a dead 16-year-old mare. Based on histopathological examination and the detection of acid-fast rods after staining by the Ziehl-Neelsen technique, tuberculosis was suspected. Mycobacterium avium subsp. avium of serotype 2 and IS901+/IS1245+ ...

Background. Tuberculosis lymphadenitis is one of the most common forms of all extrapulmonary tuberculosis. Objective. To evaluate the magnitude of M. tuberculosis from lymph node biopsy paraffin-embedded sections among suspected patients visiting the Jimma University Specialized Hospital. Method. A cross-sectional study design of histological examination among lymph node biopsy paraffin-embedde...

We report two immigrants with tuberculosis of the skull base and a review of the literature. A Somalian man presented with bilateral otitis media, hearing loss, and facial and abducens palsy. Imaging showed involvement of both mastoid and petrous bones, extending via the skull base to the nasopharynx, suggesting tuberculosis which was confirmed by characteristic histology and positive auramine ...

Acid fast bacteria (AFB) are cell walls containing complex lipids so that in Ziehl-Neelsen staining they can bind dyes because not washed off by 3% HCl Alcohol (Alcoholic Acid). One of the host factors pulmonary tuberculosis is smoking habits and exposure. Smoking will damage defense mechanism lungs, which causes lungs to be more easily infected with germs. The purpose this study was determine ...
