bacteriapathogenimage analysisFor more than a century, blood agar plates have been the only test for beta-hemolysis. Although blood agar cultures are highly predictive for bacterial pathogens, they are too slow to yield actionable information. Here, we show that beta-hemolytic pathogens are able ...
Nocardia is catalase-positive and grows as yellow-white to orange colonies on Sabouraud’s agar. Biochemical testing is necessary to differentiate among Nocardia spp. There are no reports of successful treatment of nocardiosis in nonhuman primates. Anaerobic Bacteria Actinomyces Organisms of t...
Occasionally, the bacteria are rod-shaped or pleomorphic. (C) Colonies of S. sanguinis incubated on blood BHI agar plate. (D) Smooth colonies of S. sanguinis incubated on MS agar plate. (E) α-hemolytic zone of S. sanguinis incubated on blood BHI agar plate (stereomicroscope). S. ...
The Gram-positive bacteria S. mutans (ATCC 35668) and S. sobrinus (ATCC 27607) purchased from the Persian Type Culture Collection (PTCC, Tehran, Iran). The strains were grown on blood agar (Biolife, Italy) containing 7 % fresh horse blood and maintained at 37 °C for 48 h. Antibacteria...
