The authors describe the isolation and identification of a virus from bovine fetal kidney cells maintained in culture for 30 to 45 days. The virus was characterized as a herpesvirus of the infectious bovine rhinotracheitis in cell culture by the evidence of cytopathogenic effect in bovine kidney and testis cultures and serologically by a neutralization test using rabbit anti-infectious bovine rhinotracheitis sera.

Unlabelled: Bovine herpesvirus (BoHV) infection poses a significant threat to the healthy development of the cattle industry. BoHV-1 primarily causes infectious bovine rhinotracheitis, while BoHV-5 is associated with bovine necrotic meningoencephalitis. These two pathogens not only exhibit a high correlation in antigenicity and genetic background but, more importantly, can establish latent infections within the bovine ganglion.

Bovine herpesvirus type 1 (BoHV-1) is a widespread respiratory infection that significantly impacts cattle health worldwide. To address this issue in China, we previously developed a novel double gene-deleted vaccine targeting gG and tk. In this study, we further evaluated the efficacy of this vaccine by challenging vaccinated cattle with a prevalent wild-type BoHV-1 strain and comparing its effectiveness against a commercially available inactivated BoHV-1 vaccine.

Regulation (EU) 2016/429 introduces comprehensive guidelines for managing transmissible animal diseases, including zoonoses. The subsequent Commission Implementing Regulation 2018/1882 categorizes these diseases into five groups, each with specific responses, ranging from mandatory eradication to optional eradication or surveillance. Key regulatory priorities include enhanced animal traceability, biosecurity, wildlife pathogen control, sustainable farming practices, and minimizing the impact of diseases on public health, animal health, and the environment.

Two experiments evaluated the effects of an injectable trace mineral (ITM) solution at weaning on trace mineral (TM) status, inflammatory and antioxidant responses, grazing behavior, response to vaccination, and growth of beef calves. Experiment 1 used 86 Nellore calves (40 females and 46 males; body weight [BW] = 198 ± 30.8 kg; 8 ± 1 mo of age) weaned (day 0) and assigned into one of two treatments: saline (0.

Background: Infectious bovine rhinotracheitis (IBR) is a global contagious respiratory disease of ruminants caused by Bovine Herpes virus-1 (BoHV-1). It causes substantial financial losses in the dairy industry worldwide and is considered one of the most important causative agents of abortion and reproductive problems in dairy cattle.
Aim: This study aimed to estimate the seroprevalence of IBR and the related risk factors in the dairy population in Gharbia governorate, Egypt.
