Leptospira Vaccine

Fort Dodge Animal Health announces its introduction of LeptoVaxTM 4, the newest member of the Duramune' line of Leptospira vaccines. Providing a unique standard of protection against canine leptospirosis, LeptoVax 4 includes the most relevant Leptospira serovars grippotyphosa, pomona, icterohaemorrhagiae and canicola, the company says.

Leptospirosis is a potentially life-threatening disease and is reported to be the number one infectious cause of acute renal failure in dogs. The primary reservoir for these newly recognized serovars are commonly encountered wildlife, such as raccoons, opossums, skunks and rodents. This means virtually all dogs are at risk of being exposed—whether they live in a rural environment or in a suburban neighborhood.

"The number of canine leptospirosis cases has risen dramatically in recent years, with most cases caused by emerging serovars grippotyphosa and pomona," says Mike LaRosh, DVM, director of Companion Animal Professional Services for Fort Dodge Animal Health. "LeptoVax 4 and other Duramune Leptospira vaccines are the only vaccines proven effective against the two emerging serovar threats, as well as the traditional serovars."

To minimize the safety concerns historically associated with the use of vaccines containing the entire Leptospira bacteria, Fort Dodge uses an innovative process to manufacture its Leptopsira vaccines. This process, known as subunit technology, results in a product proven to be both safe and effective under field conditions, the company says.

"The final result of this process is a purified vaccine containing the majority of surface Leptospira immunogens necessary for protection," LaRosh says.
