Mycobacterium avium subspecies paratuberculosis (MAP) is an obligate pathogenic bacterium in the genus Mycobacterium. It is often abbreviated M. paratuberculosis or M. avium ssp. paratuberculosis.
It is the causative agent of Johne's disease, which affects ruminants such as cattle, and also perhaps the human disease Crohn's disease. The type strain is ATCC 19698 (equivalent to CIP 103963 or DSM 44133). Pathophysiology MAP causes Johne's disease in cattle and other ruminants, and it has long been suspected as a causative agent in Crohn's disease in humans; this connection is controversial. Recent studies have shown that MAP present in milk can survive pasteurization, which has raised human health concerns due to the widespread nature of MAP in modern dairy herds. MAP is a slow growing organism and is difficult to culture.
NSW DERPARMENT OF PRIMARY INDUSTRIES - Ovine Johne's Disease. The National OJD Management Plan The new national five year management plan developed by the SheepMeat Council of Australia and WoolProducers Australia for Ovine Johne’s disease will commence on 1 July 2013.
There are no movement restrictions into or within NSW on account of OJD. All sheep entering NSW must be accompanied by a completed National Sheep Health Statement which is required as a vendor declaration for footrot.

O exame anatomopatológico revelou a presença de bacilos álcool ácido resistentes na coloração de Ziehl-Neelsen, e o diagnostico definitivo foi feito pelo método PRA (PCR Restriction Analysis) a partir de tecidos emblocados em parafina. Este estudo visa alertar o possível potencial zoonótico deste agente em aves mantidas domiciliadas. Palavras-chave: Mycobacterium avium; Psitacídeos, Patologia, Aves. The genus Mycobacterium involves a group of ubiquitous organisms with more than 80 species. Each of them may be classified as saprophytic, potentially pathogenic for men and other animals, or strictly pathogenic. For a long time, Mycobacterium avium and M. intracelullare were considered to be the same agent, but nowadays they are classified as different species (4).
PARA Report/ Press Release 13/08/04 New milk research finds infectious bacteria survives pasteurization. JOHNE'S INFORMATION CENTER. APHIS USDA 12/03/09 Johne's Disease in Sheep. Irish Veterinary Journal 2009, 62:526-532 (1 August 2009) Direct and indirect effects of johne's disease on farm and animal prod. Study design This retrospective case study was undertaken on a single commercial dairy herd (the 'case herd') located in the province of Munster in Ireland.
The case study is an investigation of the effect of Johne's disease on production in the herd confirmed. The Munster region in the south west of Ireland is the country's premier dairy area: in 2006, 61% of dairy calves in Ireland were born in this province . The study was conducted over 11 years (the 'study period') from 1994 (the year prior to the first JD clinical case on the farm) to 2004. Health and production data from all cows in milk during this period (the 'study animals') were considered. Study farm On the study farm, there were an average of 71 cows in milk during the study period, with an annual average milk production of 5550.3 kg/year (SD = 431.2). Eventually, the farmer requested that the three animals that were currently very 'poorly' in the herd be tested for Johne's disease in 2000.

VOXY 27/11/09 New Johne's Disease Website Launched. A new website has been launched to link farmers with the latest information on the animal wasting Johne's disease.
"The website (www.jdrc.co.nz) is the public face of the Johne's Disease Research Consortium which is developing tools to help farmers control the disease," says Consortium Chairman Dr Andrew MacPherson. "Each year the impact of Johne's disease on animal health and production is estimated to cost up to $88 million in New Zealand. "Our website provides farmers with up-to-date information about Johne's disease, and management practices for controlling the disease in New Zealand cattle, sheep and deer farming systems.
" The website also tells farmers about the Consortium's research programme which aims to reduce the number of herds, and animals within herds, that are infected with Johne's disease. "Because it is a complex disease, there are several areas of work," says Dr MacPherson. Clin. Microbiol. Rev. July 2001 Mycobacterium avium subsp. paratuberculosisin Veterinary Medicine. Interaction of Survival within macrophages is a hallmark of .
Recent evidence indicates that simultaneous intracellular multiplication and killing of occurs, reflecting an initial T-helper 1 (Th1) cellular immune response of the host ( 331 ). The nutritional and hormonal status of an animal may also influence its susceptibility to infections. Reduced dietary calcium (Ca 2+ ) protects beige mice from infections ( 276 ), but a corresponding increase in endogenous 1,25-(OH) 2 D 3 (vitamin D) levels reverses the beneficial effects of low Ca 2+ levels ( 276 , 278 ).
Additionally, transient exposure of monocytes to growth hormone or prolactin enhances intracellular multiplication of in primary bovine monocytes ( 109 ). Because the levels of these hormones also fluctuate during parturition and lactation, it is possible that similar alterations in the hormonal milieu might also influence the intracellular multiplication of in bovine mononuclear phagocytes in vivo.
