FIG. 7.
Severity of oviduct pathology is proportional to the amount of Nigg in the inoculum. The figure panels show representative oviduct histologic sections from a mouse sacrificed for histopathology on day 14 after infection with the following inocula: (A) 105 Nigg; (B) 104 Nigg plus 105 CM972 (Nigg ratio, 1:10); (C) 103 Nigg plus 105 CM972 (Nigg ratio, 1:100); (D) 105 CM972. Each section is shown at ×100 magnification. Data represent the means ± standard deviations of the results obtained for the individually scored oviducts from each group of 5 mice in a single experiment.
