Pathological and Molecular Studies of Neospora caninum Infection in Aborted Bovine Foetuses in Khorasan Razavi Province, Iran

open access: yesVeterinary Medicine and Science, Volume 11, Issue 3, May 2025.
Aborted bovine foetuses were collected from dairy cattle in Khorasan Razavi province. Brain samples of aborted foetuses were tested to detect N.caninum infection using nested PCR and histopathological examination. In addition, blood samples were collected from dairy cattle that had aborted PCR‐positive foetuses and were analysed using ELISA .

Ribonucleotides in Infectious Bovine Rhinotracheitis Virus DNA

open access: yesJournal of General Virology, 1976
Infectious bovine rhinotracheitis (IBR) virus was grown in the presence of 5-3H-uridine in a continuous line of bovine kidney cells. 5-3H-uridine was found to be associated with viral nucleocapsids. Furthermore, purification of the viral nucleic acid present in nucleocapsids illustrated that 5-3H-uridine was part of the viral nucleic acid. Purification
