Chronic form of experimental rabies in mice

Acta Virologica
M A SelimovM B Korolev


The L-28 strain of street rabies virus isolated from the salivary gland of a red fox caused chronic infection in mice. After intracerebral (i.e.) infection with virus-containing fox salivary gland suspension, 13.9% of mice showed clinical signs of disease for 11--52 days. Clear-cut stages of irritation and paralysis were distinguished in the course of infection of mice. The diagnosis of chronic rabies in mice was confirmed by immunofluorescence and isolation of virus by i.c. inoculation of mice. Electron microscopic examination of the Ammon's horn of mice revealed a slow development of morphological changes connected with the formation of virus-specific structures. The gradual increase in the number and size of aggregates of viral ribonucleoprotein was followed by the appearance of membranous and tubular structures. Along with the latter, typical bullet-shaped particles of rabies virus were found in some neurons on the 43rd day of infection.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
