FIG. 4.

Quantitation of IFN-γ mRNA in spleens (A), renal lymph nodes (LN) (B), and popliteal lymph nodes (C). Gerbils were necropsied at 3 h, 24 h, 3 days, 7 days, and 28 days after i.d. inoculation with B. pahangi L3. mRNA levels were measured by RT-PCR, and values are expressed as mean severalfold changes compared with values from control animals. Superscript letters indicate statistical significance (P < 0.05). Values with the same letter are not statistically different. No statistically significant differences were found in the renal lymph nodes (P = 0.094).
