|
|
|
General Information: |
| Species: |
|
Swine |
| Disease: |
|
Ileitis |
| Contact Agency: |
|
USDA, APHIS, VS, CEAH, National Animal Health Monitoring System (NAHMS) |
| Overview: |
|
The Collaboration in Animal Health and Food Safety Epidemiology (CAHFSE) is a joint effort among three agencies of the United States Department of Agriculture: the Animal and Plant Health Inspection Service (APHIS), the Agricultural Research Service (ARS), and the Food Safety and Inspection Service (FSIS). The mission of this important surveillance effort is to enhance overall understanding of bacteria that pose a food-safety risk by monitoring these bacteria on farm over time and to provide a means to routinely monitor critical diseases in food-animal production. A particular emphasis of CAHFSE is to address issues related to bacteria that are resistant to antibiotics. Swine is the first commodity to be studied by the CAHFSE program. Ileitis, Porcine Reproductive and Respiratory Syndrome (PRRS), and trends in prevalence of Salmonella, Campylobacter, generic E. coli, and Enterococcus species are included in the program. This report presents the ileitis component. The program has been suspended pending the identification of funding sources. Final samples were collected in April-June 2006. |

Disease Information: |
| Disease Information: |
|
Ileitis in swine is caused by the bacterium Lawsonia intracellularis and has a worldwide distribution. Rodents may be a source for infection as Lawsonia intracellularis has been isolated in mice. The more common, non-hemorrhagic form of the disease affects 40-80 pound pigs and is characterized by the sudden onset of watery to pasty, brownish or faintly blood-stained diarrhea. There is also a hemorrhagic form of ileitis that is characterized by cutaneous pallor, weakness, and passage of black, tarry feces. Ileitis can also cause pregnant gilts to abort. Treatment consists of administration of various antibacterials parenterally to acutely affected pigs and by feed or water to the remainder of the group to reduce the severity of the enteritis. |

Details about the Surveillance Program or Study: |
| Population: |
|
Together, the farms in the CAHFSE program have included between 110,000 and 130,000 market hogs per quarter . |
| Coverage: |
|
The CAHFSE program has been conducted in 5 states-- Iowa, Minnesota, Missouri, North Carolina, and Texas. |
Data collection
location(s): |
|
Data are collected on farm for the ileitis component of CAHFSE. |
| Samples Collected: |
|
Blood samples are collected for the ileitis component of CAHFSE. Questionnaires are also completed by CAHFSE participants. |
| Data Collected: |
|
Animal, herd, and premises data are collected for CAHFSE. |
| Frequency: |
|
Questionnaire data, blood, and fecal samples are collected quarterly for CAHFSE. The program has been suspended pending the identification of funding sources. Final samples were collected in April-June 2006. |
| Reporting / Information Distribution Process: |
|
Quarterly, the NAHMS staff produces a report of antimicrobial resistance, summary ileitis test results, and a clinical report of ileitis in the herd. An annual report of summarized results is also produced. These reports are available on the internet. |
| Scope: |
|
In the first year of the CAHFSE (July 2003 through July 2004), 39 sites were enrolled in the project. |
