Prevalence of antibodies to four bovine rotavirus strains in different age groups of cattle.

Prevalence of Bovine Viral Diarrhoea Virus antibodies and antigen among the aborted cows in industrial dairy cattle herds in Mashhad area of Iran

The measurement of antibody responses of animals exposed to BVDV either through a natural exposure or an immunization protocol is still a standard procedure. For BVDV, the test formats have been largely limited to ELISA which is a valuable diagnostic test to measure the level of BVDV specific antibodies as well as antigen in blood samples. In the present study, 120 blood samples were collected ...

Seroepidemological Survey for Antibodies against Infectious Bovine Rhinotracheitis and Bovine Herpes 4 Viruses among Cattle in Different Provinces of Iran.

Comparative prevalence of Bovine Viral Diarrhea Virus antibodies among native and imported cattle in north of Sistan and Baluchistan- Iran

Background and Aims: Sistan is a major pole in dairy production and genetic resource for the unique sistanian breed in the southeast of Iran. This region has a wide border with Afghanistan and cattle imports are done through this border.  The   main aim of this study was to compare the seroprevalence of Bovine Viral Diarrhea Virus (BVDV) infection rate using direct Enzyme-linked ...

Cattle develop neutralizing antibodies to rotavirus serotypes which could not be isolated from faeces of symptomatic calves.

Neutralizing antibodies against 10 serotypes of rotavirus were measured in sera from different age groups of German cattle. Only five of 143 sera did not neutralize heterologous serotypes. Sera from 64 of 76 calves younger than 1 year neutralized bovine rotavirus NCDV (serotype 6). From these calves, sera 54, 26, 51, 24, 12, 10 and 37, in neutralized addition, the heterologous serotypes 1, 2, 3...

Prevalence of Neospora caninum and Toxoplasma gondii Antibodies in Bulk Milk of Dairy Cattle, Mashhad, Iran

Neospora caninum (N. caninum) and Toxoplasma gondii (T. gondii) are both obligate intracellular protozoan parasites, which have gained considerable attention because of their role in bovine abortion. This study aimed to detect anti-N. caninum and -T. gondii in bulk milk of dairy cattle, Mashhad, Iran. The bulk milk samples were collected from July 2014 to June 2015 and analyzed for anti-N. cani...
