“…L. ivanovii is almost exclusively recovered from ruminant, yet it can rarely infect humans 21 and has not been described to disseminate to the CNS, while Lm is the only one that leads to CNS infection, in humans and in domestic ruminants, 19 , 20 as well as in wild or domestic species such as cervidae (fallow deer 22 ), camelidae (llama 23 ), rodents (chinchilla and squirrels 24 ) and to a lesser extent carnivores: felidae (cat and cougar 25 , 26 ) and canidae (dog, fox and racoon dog 24 , 27 ). Lm -associated CNS infection can manifest as meningitis, meningoencephalitis, brain abscesses and rhombencephalitis, 28 the latter being typically associated with this bacterium.…”

Among bacteria that reach the central nervous system (CNS), Listeria monocytogenes (Lm) is one of deadliest, in human and ruminant. This facultative intracellular bacterium has the particularity to induce meningitis, meningoencephalitis and rhombencephalitis. Mechanisms by which Lm accesses the CNS remain poorly understood, but two major routes of infection have been proposed, based on clinical, in vitro and in vivo observations. A retrograde neural route is likely to occur in ruminants upon crossing of the oral epithelium, and this probably accounts for the observation that Lm induces almost exclusively rhombencephalitis in these animals. In contrast, the hematogenous route is likely the most frequent in human, in whom bacteria circulating in the blood, either free or associated with leukocytes are thought to breach the blood-brain barrier. New animal models that faithfully reproduce the hallmarks of human neurolisterisosis will allow addressing the molecular mechanisms underlying Lm ability to induce CNS disease, and improve our understanding of the pathophysiology of this deadly infection.

“…1 Listeriosis case reports are more extensively written for humans than animals. [5][6][7] There are isolated case reports of dogs contracting listeriosis, [8][9][10] however none of the cases involve osteomyelitis. Osteomyelitis caused by listeriosis has been reported in several human cases.…”

Case description: A young, sexually-intact, male dog was referred for approximately three months duration proliferative, periosteal reaction of multiple bones. Clinical findings: Culture and sensitivity of both bone and blood grew Listeria monocytogenes. Histopathological examination of bone did not find any evidence of neoplasia. Treatment and outcome: The patient was started on parenteral antibiotic based on culture and sensitivity results as well as opioid therapy and continued on intravenous fluids with other supportive care as need. The patient rapidly improved. At week 6 the periosteal reaction was still evident. At week 19 the periosteal reaction in all bones had resolved. Clinical relevance: This case highlights listeriosis as a possible cause of osteomyelitis in dogs. Listeria monocytogenes is a ubiquitous organism within the environment. Certain predisposing factors contribute to the likelihood of developing listeriosis. In our patient, it is likely that there is a deficiency of cell-mediated immunity which allowed clinical disease to occur.

“…IHC for PrP Sc was performed using the mAb T1 [27] or F99/97.6.1 (VMRD, Pullman, WA, U.S.A.) as previously described [22,23,24]. Additionally, formalin-fixed and paraffin-embedded tissue sections were stained with an anti- Listeria monocytogenes (Lm) polyclonal antibody [1] and a secondary Alexa Fluor 546-conjugated antibody for dual immunofluorescence. We used brains of sheep affected with atypical scrapie obtained from the Veterinary Laboratories Agency (currently the Animal and Plant Health Agency, Addlestone, Surrey, U.K.) and sheep with classical scrapie from the NIAH archive as positive controls for the WB and IHC tests.…”

A Corriedale ewe was confirmed as the first atypical scrapie case during an active surveillance program for transmissible spongiform encephalopathies in small ruminants in Japan. The animal was homozygous for the AF141RQ haplotype of PRNP. The animal showed clinical neurological signs possibly due to listeriosis before culling. Western blot analysis showed an unusual multiple banded pattern with a low-molecular fragment at ~7 kDa. Histopathology revealed suppurative meningoencephalitis caused by listeriosis in the brainstem. Fine granular to globular immunostaining of disease-associated prion proteins was mainly detected in the neuropil of the spinal tract of the trigeminal nerve and in the white matter of the spinocerebellar tract. Based on these results, this case was conclusively diagnosed as atypical scrapie with encephalitic listeriosis.
