Abstract

There are several infectious agents of domestic cattle that can also be present in free-living ruminant populations. These include bovine herpesvirus 1 (BoHV-1) and bovine viral diarrhea virus (BVDV) which are the causative agents of infectious bovine rhinotracheitis and bovine viral diarrhea, respectively. The study was conducted on serum samples from 59 red deer, 24 roe deer, and 3 fallow deer (86 in total), originating from two geographically separate areas of Poland. The samples were tested with commercially available ELISA tests for BoHV-1 and BVDV. The overall seroprevalence was 5.8% and 3.5%, respectively. All positive samples originated exclusively from red deer. Because of BoHV-1 ELISA cross reactivity with cervid herpesvirus 1 and 2 (CvHV-1 and -2) the nature of alphaherpesviruses infecting the sampled animals could not be assessed.

Abstract

In the present study on Bubalus bubalis of the Campania Region (Italy) the serum levels of derivatives of reactive oxygen metabolites (d-ROMs), anti-ROM and oxidative stress index (Osi) were evaluated. These data were then related to the seropositive status of the animals against alpha-herpesviruses, precisely Bubaline herpesvirus 1 (BuHV-1) and Bovine herpesvirus 1 (BoHV-1). Clinically healthy Mediterranean buffaloes were selected for this study. The serum samples of these animals were taken, and d-ROMs, anti-ROM and Osi were measured using commercially available tests. The preliminary data demonstrated that animals seropositive to both BuHV-1 and BoHV-1 present more oxidative stress than seronegative animals, as revealed by a significant increase in d-ROMs. Our results provide, for the first time, insight into the reac- tive oxygen species (ROS) modulation induced by the herpesvirus in Bubalus bubalis.
