Histopathology in study of congenital tularemia with neuroinvasive disease, Utah, USA. Histopathological evaluation revealed the presence of subacute suppurative salpingitis with serositis. A) Hematoxylin and eosin–stained tissue showing abundant necroinflammatory debris in the lumen of the left fallopian tube. The endosalpinx was edematous, and infiltrating neutrophils and mononuclear cells were seen in the lamina propria and tubal epithelium. Original magnification ×200. B) Higher-power microphotograph highlights immunostaining within intracellular coccobacilli (arrows). Original magnification ×630. C) Francisella tularensis immunohistochemistry showing immunoreactive granular forms of bacterial antigens (arrows) within areas of the luminal necroinflammatory infiltrate. Original magnification ×200.
