Lower power H & E photomicrographs illustrating the implanted (a) and contralateral control (b) cochleae of a rat 32 hours following IP inoculation of 4 x 106 CFU S. pneumoniae. This animal exhibited clinical and histological (CNS) evidence of meningitis. However the scalae of both cochleae were devoid of gross infection. Higher power photomicrograph of Gram stain from basal turn of the contralateral cochlea (c), the lateral wall of the scala media of the contralateral cochlea (d), the modiolus of the ipsilateral cochlea (e) and the internal acoustic meatus of the contralateral cochlea (f), illustrates the presence of bacteria (arrows). The approximate location of the higher power micrographs (e,f) are illustrated in (a) and (b). sv: stria vascularis. Scale bar: (a) & (b) 200 μm; (c) 100 μm; (d-f) 10 μm.
