Species not Established in the U.S.

The following species of concern represent examples of why we must increase our efforts in early detection and rapid response and prevention of new introductions. See Manager's Tool Kit - Early Detection and Rapid Response: Species not Established in the U.S. for general resources and other species information.

This information is provided as an educational tool and is not inclusive of all invasive microbial species not yet established in the U.S.

Alder dieback - Invasive.org

Scientific name: Phytophthora alni Brasier and Kirk

Common name: Alder dieback

Native To: Europe (Cree 2006)

Date of U.S. Introduction: n/a

Images:

Means of Introduction: Nursery stock, i.e., rooted plants, and contaminated soil are the most likely means of long-distance transport of the pathogen (Cree 2006)

Impact: Infects and kills alder trees (trees of the genus Alnus) (Gibbs et al. 1999)

Chrysanthemum white rust - Invasive.org

Scientific name: Puccinia horiana Henn.

Common name: Chrysanthemum white rust

Native To: Asia (Hernández 2004)

Date of U.S. Introduction: There have been several outbreaks in the U.S., but the disease has been eradicated each time. (Hernández 2004)

Images:

Means of Introduction: Potential of this organism to be transported with prohibited articles of chrysanthemum. (APHIS 2008)

Impact: Has become established throughout most of the world. If established in the U.S., chrysanthemum white rust could have significant impact on both greenhouse and outdoor chrysanthemum plants. (Hernández 2004)

Healthy hogs - ARS photo gallery

Scientific name: Family Flaviviridae, genus Pestivirus

Common name: Classical swine fever, hog cholera

Native To: Origin unknown; may be native to the U.S. (ARS 2008)

Date of U.S. Introduction: Ohio reported in 1833. Eradicated in the U.S. in 1978 (APHIS 2008)

Images:

Means of Introduction: The virus is most often transmitted through the ingestion of contaminated feed or garbage. (APHIS 2008)

Impact: Highly contagious, viral disease of pigs that is usually fatal. The disease is still present in many countries, so there is a risk that it could become established in this country once again. While classical swine fever does not cause foodborne illness in people, economic losses to pork producers would be severe if the disease were to become established again in this country. (APHIS 2008)

Research personnel examing animal for foot and mouth disease - USDA

Scientific name: Family Picornaviridae, genus Aphthovirus

Common name: Foot and mouth disease, hoof-and-mouth disease

Native To: First observed in 1514 in Italy (AVMA 2007)

Date of U.S. Introduction: Nine Outbreaks of foot and mouth disease occured in the U.S. between 1905 and 1929. It is widespread through the world, but it was eradicated from the U.S. in 1929. (Segarra and Rawson 2001)

Means of Introduction: Contact with infected animals (CFSPH 2007); eating infected meat (Segarra and Rawson 2001)

Impact: Contagious disease of cattle, swine, sheep, goats, deer, and other cloven-hoofed animals. Foot and mouth disease is considered to be the most economically devastating livestock disease in the world, and represents a worst-case scenario for livestock diseases because of the variety of species involved, rapid spread, and difficulty in controlling outbreaks. The 2001 FMD outbreak in Great Britain resulted in the slaughter of more than 6 million animals and an estimated economic loss of 20 billion dollars. (AVMA 2007)
