2%) were identified as potential positives by the presence of gross internal tissue nodules and acid-fast bacteria in tissue smears (Fig.
Two Mountain Whitefish samples from the 2009-2010 collection, positive for acid-fast bacteria by tissue smear, were examined by histology at WADDL.
Three Rainbow Trout tested positive for acid-fast bacteria by tissue smear and were examined by histology at WADDL.
Effects of extracts from seaweeds on the growth of some
acid-fast bacteria," Nippon Saikingaku Zasshi, 11, pp.
Second, the finding that the macrophages in these lesions contained large numbers of
acid-fast bacteria supports the conclusion that mycobacterial infection caused the lesion.
Special stains for fungi and
acid-fast bacteria were negative.
Various organs and tissues from seven banded mongooses and a suricate were fixed in 10% buffered Formol-saline, embedded in paraffin wax, cut into 4-[micro]m sections, and stained with hematoxylin and eosin, as well as Kinyoun's method for acid-fast bacteria (AFIP modification) (7).
Acid-fast bacteria were detected on Ziehl-Neelsen-stained impression smears, and Mycobacterium species were isolated from both banded mongooses and the suricate specimens.
They discussed
acid-fast bacteria, nontuberculous mycobacteria, gram-positive bacteria, and fungi as possible causes (3) but more recently concluded that the specific etiologic agent(s) for HP among workers exposed to (MRF) aerosol remain(s) unknown (2).
