Infection of Neurosecretory Hypothalamic Neurons by SB after i.v. Inoculation.

<p>The panels show the hypothalamic paraventricular (PVN; panel A, D and F), arcuate (ARC; panel B) and supraoptic (SO; panel C, E and G) nuclei of mice inoculated i.v. with 10⁷ SB four days before euthanasia. The sections were stained immunohistochemically against RV only (panel A–C) or co-stained against RV and antidiuretic hormone (ADH; panel D and E) or oxytocin (Oxy; panel F and G). Abbreviation: 3^rd V, third ventricle. Black or white bars represent 20 (panel D–G), 25 (panel B, C) or 75 µm (panel A). Arrowheads point to neurons and fibers containing both RV and ADH, or Oxy respectively.
