Mycobacterium avium subspecies paratuberculosis and Crohn’s disease: a systemic review and meta-analysis. M. Feller et al. The Lancet Infectious Diseases 7(9):607-613, September, 2007. Abstract: This systematic review assesses the evidence for an association between Mycobacterium avium subspecies paratuberculosis (MAP) and Crohn's disease. We analysed 28 case-control studies comparing MAP in patients with Crohn's disease with individuals free of inflammatory bowel disease (IBD) or patients with ulcerative colitis. Compared with individuals free of IBD, the pooled odds ratio (OR) from studies using PCR in tissue samples was 7·01 (95% CI 3·95–12·4) and was 1·72 (1·02–2·90) in studies using ELISA in serum. ORs were similar for comparisons with ulcerative colitis patients (PCR, 4·13 [1·57–10·9]; ELISA, 1·88 [1·26–2·81]). The association of MAP with Crohn's disease seems to be specific, but its role in the aetiology of Crohn's disease remains to be defined.

Online education: something for everyone. Wisconsin Department of Agriculture, Trade and Consumer Protection in partnership with the University of Wisconsin, School of Veterinary Medicine and WisTREC provide multiple online Johne’s disease educational opportunities. These easy-to-use narrated modules focus on Johne’s disease control issues for dairy, beef and goat producers. Additional modules addressing Johne’s disease in sheep, deer, llamas and bison will be posted on-line in the near future. A 2 minute introduction can be seen here (requires Flash player). All of the online training programs can be found at: http://www.vetmedce.org/index.pl?op=show;id=133363 The producer modules are also found on the Presentations page of this website: http://johnes.org/presentations.shtml |

U.S National Advisory Committee on Microbiological Criteria for Foods to consider the importance of M. paratuberculosis. The NACMCF is a large committee that brings together representatives from FDA, USDA, CDC, academia and multiple food industries. It meets March 21-24, 2006 in Arlington, VA. On the agenda for March 23, 8:30 AM to 5:00 PM is work of the Subcommittee on Assessment of the Food Safety Importance of Mycobacterium avium subspecies paratuberculosis, David Acheson, Chair. For more information, visit the USDA-FSIS website. http://www.fsis.usda.gov/News_&_Events/Agenda_NACMCF_Mar2006/index.asp For background information about the NACMCF visit this website. http://www.fsis.usda.gov/About_FSIS/NACMCF/index.asp |

| Culture of Mycobacterium avium subspecies paratuberculosis from the blood of patients with Crohn's disease. The following study concerning MAP and Crohn's disease was reported in the Lancet recently. Summary: Crohn's disease, a form of inflammatory bowel disease, resembles some aspects of tuberculosis, leprosy, and paratuberculosis. The role of Mycobacterium avium subspecies paratuberculosis (MAP) in Crohn's disease is controversial. Tested for MAP was completed by PCR and culture in buffy coat preparations from 28 individuals with Crohn's disease, nine with ulcerative colitis, and 15 without inflammatory bowel disease. MAP DNA in uncultured buffy coats was identified by PCR in 13 (46%) individuals with Crohn's disease, four (45%) with ulcerative colitis, and three (20%) without inflammatory bowel disease. Viable MAP was cultured from the blood of 14 (50%) patients with Crohn's disease, two (22%) with ulcerative colitis, and none of the individuals without inflammatory bowel disease. Current use of immunosuppressive medication did not correlate with a positive MAP culture. Sequencing of PCR products from MAP cultures confirmed the presence of the MAP specific IS900 fragment. |

M. paratuberculosis found in U.S. milk.
Viable (living) M. paratuberculosis organisms (the mycobacterium that causes Johne's disease), were found in low numbers in commercially pasteurized milk purchased from stores in California, Minnesota and Wisconsin according to research conducted by Dr. Jay Ellingson, Marshfield Clinic Laboratories, Marshfield, WI, USA . Of 702 samples tested, 2.8 percent contained viable M. paratuberculosis organisms. This study's results agree with previous research conducted in Great Britain and were presented recently at the International Association for Food Protection conference. The full study will be presented at the International Colloquium on Paratuberculosis, Aug. 14 - 18, Copenhagen, Denmark ( http://www.8icp.dk/ ). |

OJD found in Western Australia. Ovine Johne's disease, a chronic, incurable bacterial disease of sheep, was detected in Western Australia this week, but should not affect its "free zone" status.Victorian ministerial OJD advisory committee chairman Frank Tobin said while low levels of infection may exist, it could take years to detect. Tobin added that the industry should not overreact after a West Australian property was quarantined following the discovery of several sheep suffering from OJD. "It's very easy to lose producer support if you overreact and we shouldn't presume this is any more than it is," he said. "It won't alter Victoria's view of Western Australia and that is, that they have a low level of infection. What we'll be keen to see is the follow-up and the flow-on effects." The WA Department of Agriculture chief veterinary officer Peter Buckman said the outbreak in the state's central region would be investigated. Western Australia is the only state recognized under national rules as an OJD "free zone" and is expected to maintain that status. |

Surgery, VMAC Bronx, Bronx NY USA, in the Personal View section titled: "Is Crohn's disease caused by a mycobacterium? Comparisons with leprosy, tuberculosis, and Johne's disease." The article is in the form of a review but also presented as a professional opinion. It is a useful compilation of many research publications and has 148 references. The abstract of the article can be viewed on the Lancet web site.
A reprint of the full article can be obtained from the publisher as a pdf file for US$30, after registering on The Lancet website: http://infection.thelancet.com/home |
