Genetic Profiles of Bovine Herpesvirus 1 Strains Isolated from Cattle in Poland
نویسندگان
چکیده
The purpose of the study was to determine subtypes of BHV1 strains isolated from cattle in Poland. In total five different strains of BHV1 were isolated during the last years. All isolates as well as four archival and two reference BHV1 strains were analysed by PCR and restriction enzyme analysis. Specificity of the strains was confirmed by PCR with primers complementary to the nucleotide sequence of gD gene. Subsequently, genomic DNA of the tested strains was digested with endonucleases Hind III and Hpa I. Restriction enzyme analysis revealed that all recently isolated BHV1 strains belonged to the BHV1.1 subtype. Among archival viruses, two strains had restriction pattern similar to the subtype BHV1.1 and two others to the subtype BHV1.2a. The presented study showed that currently subtype BHV1.1 is dominant in cattle population in Poland.

Antibiotic Susceptibility and Plasmid Profiles of Staphylococcus aureus Strains Isolated from Bovine Subclinical Mastitis in Tabriz, Iran
ABSTRACT Background and Objectives: Mastitis caused by Staphylococcus aureus is a widely distributed disease in cattle, goats and sheep. The infection is often subclinical in cattle, leading to reduced milk production and quality, but acute catarrhal or even gangrenous inflammation may also occur. The aim of this study was to investigate resistance of S. au...
متن کاملIsolation of Bovine Herpesvirus-1 (BoHV-1) From Latently Infected/Carrier Cattle in Ahvaz
Bovine herpesvirus 1 (BoHV-1) is one of the most important infectious viruses of cattle which is considered as the causative agent of several clinical conditions in this species. Hence, we tried to isolate a local strain of the virus from carrier cattle in Ahvaz based on a strategy for reactivation of the latent infection in hosts having antibodies against the virus. Thus, 20 cattle were examin...

Bovine herpesvirus-1 (BoHV-1) causes significant disease in cattle including respiratory, fetal diseases, and reproductive tract infections. Control programs usually include vaccination with a modified live viral (MLV) vaccine. On occasion BoHV-1 strains are isolated from diseased animals or fetuses postvaccination. Currently there are no markers for differentiating MLV strains from field strai...

Bovine herpesvirus type-1 (BoHV-1) is a DNA virus that is classified in the family Herpesviridae, subfamily Alphaherpesvirinae and genus Varicellovirus. This virus causes the respiratory disease, abortion, conjunctivitis, infectious pustular vulvovaginitis or balanoposthitis and other clinical forms of the complex diseases. The aim of this study was to evaluate the seroprevalence and ri...
