Listeria monocytogenes meningoencephalitis against the background of the new coronavirus infection: a clinical case

Abstract

Background: Among the bacteria that affect the central nervous system, Listeria monocytogenes (facultative intracellular bacterium) is one of the most lethal to humans and animals. Listeriosis affects domestic and farm animals (pigs, small and large cattle, horses, rabbits, less often cats and dogs), as well as domestic and ornamental birds (geese, chickens, ducks, turkeys, pigeons, parrots and canaries). L. monocytogenes can be detected in fish and seafood (shrimp). The source of L. monocytogenes infection are animals in which the disease may manifest itself or occur in erased and asymptomatic forms followed by the transition to a long-term carriage. This pathogen is found throughout the world in foodstuffs, and most cases of infection occur through the ingestion of contaminated food. Particularly susceptible to the disease are embryos, newborns, the elderly and individuals with immunodeficiencies and chronic diseases. L. monocytogenes can cause intracranial hemorrhage, meningitis, meningoencephalitis, and rhombencephalitis. Clinical case description: This paper presents our own clinical observation of the development of severe listeriosis meningoencephalitis in a 47 year-old patient against the background of the new coronavirus infection (COVID-19). We describe the details of the clinical presentation, the treatment and the favorable outcome in our patient. Conclusion: Invasive listeriosis is a rare disease. The knowledge about the clinical manifestations of this disease is needed not only for epidemiologists and infectious disease specialists, but also for physicians of other specialties. Untimely diagnosis and inadequate antibacterial therapy are dangerous leading to severe somatic and neurological complications with a lethal outcome or disability both in children and adult persons.
