“…The postmortem examination revealed that necrotic foci in congested liver, highly congested kidney, cloudiness of the cerebrospinal fluid, thickened and congested meninges, congested brain and congestion of blood vessels of brain stem and cerebellum (Fig. 5) and the obtained results were in agreement with that obtained by (Seaman et al, 1990;El-Sawalhy et al, 1999). These results disagreed with that observed by (Al-Dughaym et al, 2001) who observed that the postmortem picture of listeriosis of sheep was bilateral keratoconjunctivitis, lung showed multiple areas of hemorrhage, marked congestion and turbid and edematous meninges.…”

“…In the terminal stage, animals become recumbent and may show convulsions. Rare cases have been described, in which limb paralysis occurred due to affection of the spinal cord alone (myelitis) without involvement of the brain [134, 163, 164]. The course of infection in small ruminants (sheep and goats) is generally acute and animals die within 1–3 days after clinical signs became apparent.…”

“…However, the neuropathological pattern of the natural disease and the observation of intraaxonal and intraneuronal bacteria (Figures 5 and 6) strongly suggest that foodborne LM cells invade the brainstem by axonal migration along various cranial nerves [87, 131, 136, 165, 254]. Correspondingly, in an outbreak of listeric myelitis in sheep ascending infection via the sensory nerves following dermatitis was suspected and subcutaneous injection of LM in the lumbar and thoracic regions may cause lumbar and thoracic myelitis in mice [163, 255]. These observations indicate that the site of bacterial invasion determines the topography of CNS lesions.…”

“…1,3,4,7 In ruminants and humans, L. monocytogenes likely reaches the CNS by centripetal axonal migration not only through the trigeminal nerve but also other cranial and spinal nerves, and spreads further rostrally and caudally within the CNS. 1,7,17 In the cat described here, the particular pattern of lesions including the presence of microabscesses in the cervical nerve roots, their maximal severity in the cervical intumescence, and gradual decrease from the spinal cord to the midbrain indicates that the bacterium may have entered the CNS via nerve roots from the brachial plexus. However, the source of infection could not be identified because the cat was a stray cat and no anamnestic information was available.…”
