Article Abstract

Non-suppurative encephalitis occurs sporadically in beef cattle in western Canada, leading to loss of animals. This retrospective study investigated the presence of viral, bacterial, and protozoal antigens or DNA in 37 western Canadian feedlot cattle with non-suppurative encephalitis for which a cause had not been identified. Cases were selected based on the age of the animal (> 7 months), and clinical history of recumbency and depression. The identification of rabies in 1 case stresses the importance of including this viral disease in the list of differential diagnoses. Because there was variation in the severity, distribution, and type of lesions, it is possible that there may be more than 1 cause, but failure to identify an infectious agent might also suggest that non-infectious agents could play a role.

Introduction: Herpes zoster (HZ) is a viral disease with a global health burden which significantly impacts on the quality of life. HZ is caused by reactivation of the varicella-zoster virus and its complications are dependent on multiple factors like immune suppression, psychological stress, malnutrition, co-morbidities, duration of HZ infection and old age. Some of the complications include secondary bacterial infection, post-herpetic neuralgia, scarring, nerve palsy, and viral encephalitis.

As a significant zoonotic disease, rabies poses substantial economic challenges for the livestock sector, highlighting the need for effective wildlife monitoring as part of a One Health approach. This study documents the first case of paralytic rabies in a lowland tapir () at the Guaycolec Wildlife Station in Formosa, Argentina. The 12-year-old male tapir exhibited neurological symptoms, including limb paralysis and dysphagia, leading to its death.

Although laboratory methods have advanced, the cause of many encephalitides is still unknown. Molecular methods like multiplex PCR and microarrays are considered to be often less sensitive than Next Generation Sequencing, whereas the latter is time-consuming and costly. These analyses require appropriate tissue preparations and are more difficult to perform on formalin-fixed, paraffin-embedded (FFPE) tissues.

To determine the occurrence of microsporidiosis in domestic pigeons in Iran, privately-owned pigeons presenting weight loss and diarrhea were tested through molecular and histopathological methods. Multiplex-PCR findings showed 57%, 30%, and 14% positivity for , , and mixed infection in the fecal samples, respectively. A novel genotype, named IrnEb1, falling into zoonotic group 1 of , and a novel genotype of , named Irn2E, clustering as a sister taxon to genotype 2B were identified in pigeons for the first time using Sanger sequencing and phylogenetic analyses.

Article Synopsis
  • Neurological diseases linked to astroviruses have been identified in various animals, including pigs and humans, with significant findings from 2017 and 2020 studies.
  • In 2017, the neuro-invasive porcine astrovirus (Ni-PAstV) 3 was found in pigs with brain inflammation in Hungary and the USA.
  • A recent study in South Korea detected multiple genotypes of porcine astrovirus in brains of affected pigs, marking the first reported case of Ni-PAstV in the country.
