The acid-fast stain
and culture examinations should be considered together to assess active TB in HIV patients.
Gram stain (Figure, C) and a modified acid-fast stain
(Figure, D) revealed gram-positive, partially acid-fast filamentous organisms branching at right angles within the eosinophilic material consistent with Nocardia organisms.
The bug was considered a rare and exotic pathogen until the mid-1980s when a modified acid-fast stain
was employed to look for Cryptosporidium in stool specimens, especially from people with impaired immune systems who suffered from HIV disease. A much larger organism was frequently associated with enteritis and was variously described in subsequent reports as a large Cryptosporidium, a fungal spore, a member of the Blastocystis species, a cyanobacterium-like body (CLB, or blue-green algae), and coccidian-like.[6-9] These organisms probably were Cyclospora and have become associated with travel or residence in developing countries.
for acidfast bacilli are usually negative.
All cases fulfilled the clinical criteria according to Chinese Society of Gastroenterology :[sup] (1) histological biopsy showed epithelioid granuloma with caseous necrosis in intestinal tissue or mesenteric lymph nodes; (2) intestinal tissue biopsy was positive for MTB on culture or acid-fast stain
; (3) patients showed a good response to anti-TB therapy with clinical manifestation consistent with active TB.
All state laboratories began routine testing with a modified acid-fast stain
As in many developing countries, the acid-fast stain
is the only bacteriologic basis for diagnosing tuberculosis (TB) in primary health care institutions in China, where facilities are limited for M.
In paraffin sections, the organism can be visualized by silver stains, tissue Gram stains, or Fite-Ferraco acid-fast stain
Eight patients had no sputum specimens submitted for acid-fast stain
Lesions can be screened for mycobacteria using an acid-fast stain
. If acid-fast bacilli are seen, M.
However, direct and acid-fast stain
microscopic examination of stool specimens from nine of the house staff physicians and one of the other employees revealed the presence of CLB.
A direct acid-fast stain
showed many acid-fast bacilli.
They were stained with Kinyoun's carbol fuchsin modified acid-fast stain
and examined by oil immersion microscopy.
