Infected mice exhibited impaired spatial learning and memory skills. a-d Results of the place navigation test: the moving tracks (a), the latency to reach platform (b), the travelled distance before reaching the platform (c) and the average swimming speed of the mice in different groups during place navigation test) (d). e, f Results of spatial probe test: the number of target location crossings of the mice during the probe trial (e) and the time spent for the mice to reach the platform during probe trial in which platform was removed (f). Values are expressed as means ± SD (n = 6). *P < 0.05, ***P < 0.001
