Disease Information
Protect Against the Most Threatening Diseases
Vira Shield® protects your cattle against these common viral and bacterial challenges:
| Diseases Covered | Disease Description |
| Bovine Viral Diarrhea (BVD) Type 1 & 2 | BVD virus is associated with Bovine Respiratory Disease (BRD) and several other disease syndromes. BVD infection causes different outcomes depending on when the cow is infected, including fetal death or PI calves. |
| Infectious Bovine Rhinotracheitis (IBR) | IBR or "red nose" causes upper respiratory tract infections. In addition to causing respiratory disease, IBR can affect reproductive performance leading to abortion or neonatal disease. |
| Bovine Respiratory Syncyntial Virus (BRSV) | BRSV invades the cell lining of the trachea and lungs and is commonly found in BRD cases, alone or with other agents. |
| Parainfluenza Type 3 (PI3) | PI3 virus alone causes only a mild respiratory disease, but it is frequently isolated with other pathogens in severe cases. |
| Histophilus somni | Histophilus somni is a bacteria that causes pneumonia and is more prevalent in stress situations where cattle are closely grouped, such as in feedlots or sale barns. |
| Vibriosis | Vibriosis – or genital campylobacteriosis – is a venereal disease that is spread from cow to bull and bull to cow during breeding. The disease often destroys the embryo at its earliest stages. |
| Leptospirosis (Lepto hardjo-bovis) |
Leptospirosis is shed in the urine and/or bodily fluids of infected animals. Research shows that Lepto hardjo-bovis is the most common cause of bovine leptospirosis in the United States and is frequently associated with reproductive losses, although an infected animal may not show clinical signs. |
