Figure Lengend Snippet: Mice were inoculated with acetic acid through the nostril, and 1 hr later, infected intranasally (i.n.) with 05ZYH33. ( A ) Sagittal views of the olfactory system. Sections of the distal nasal cavity and olfactory epithelium from uninfected (a, c, and e) and 05ZYH33-infected (b, d, and f) mice. Red or orange, 05ZYH33; green, the neuronal marker β-tubulin III; blue, DNA. NC, nasal cavity; OE, olfactory epithelium; LP, lamina propria; CP, cribriform plate; OB, olfactory bulb. ( B ) A schematic drawing of the sagittal plane of the rodent nose elucidates the compartments of the olfactory bulb (OB), olfactory epithelium (OE), nasal cavity (NC), and brain. This panel is redrawn from ‘Mouse Olfactory System’ ( inspiredpencil.com ). The dotted line indicates the anteroposterior localization of the coronal sections in C. ( C ) One hour or nine days after 05ZYH33 infection, coronal brain sections were prepared and stained with hematoxylin and eosin (H&E). The sections display the regions of the ventral striatum and basal forebrain located behind the anterior olfactory nucleus. Arrows indicate infiltrated inflammatory cells in the lower areas of the ventral striatum or basal forebrain. ( D, E ) Mice were inoculated with acetic acid or phosphate-buffered saline (PBS), and 1 hr later infected i.n. with 05ZYH33 or ∆2BSS2. ( D ) Colony-forming units (CFUs) of 05ZYH33 or ( E ) ∆2BSS2 in nasal-associated lymphoid tissue (NALT), the cerebrospinal fluid (CSF), and blood were determined 1 hr after infection.
Article Snippet: Immunostaining was conducted using a primary rabbit anti- S. suis antibody (1:100) and a mouse anti-tubulin beta III antibody (Merck Millipore, Darmstadt, Germany catalog no. mab5564, 1:300) to detect neuronal structures, and then appropriate fluorophore-conjugated secondary antibodies: donkey anti-rabbit Cy3 (Jackson ImmunoResearch Laboratories, Ely, UK, catalog no. 711-166-152, 1:1000), donkey anti-mouse FITC (Jackson ImmunoResearch Laboratories, Ely, UK, catalog no. 715-096-150, 1:500).
