AI Article Synopsis

  • Mycobacterium avium subsp. paratuberculosis causes Johne's disease in cattle and was found in dust samples from Dutch dairy farms.
  • It was detected in both the dairy barn and areas for young cattle.
  • The study suggests that bioaerosols could contribute to spreading this bacteria within farms.

Article Abstract

Mycobacterium avium subsp. paratuberculosis, the causative agent of Johne's disease in cattle, was identified in settled-dust samples of Dutch commercial dairy farms, both in the dairy barn and in the young stock housing. Bioaerosols may play a role in within-farm M. avium subsp. paratuberculosis transmission.

Studies have noted the connection between Mycobacterium avium subspecies paratuberculosis (MAP) and autoimmunity. MAP is an intracellular pathogen that infects and multiplies in macrophages. To overcome the hostile environment elicited by the macrophage, MAP secretes a battery of virulence factors to neutralize the toxic effects of the macrophage.

Paratuberculosis is an infectious disease caused by subspecies (MAP). Typically, ruminant animals including cattle, buffalo, goats, and sheep are infected with MAP. Animals get infected with MAP in a number of ways, such as by eating or drinking contaminated food or water, or by nursing from an infected mother who may have contaminated teats or directly shed the organism in milk or colostrum.

Mycobacteria infections are caused by species of the Mycobacterium tuberculosis complex (MTB) and other species called Non-Tuberculosis Mycobacteria (NTM). Identification of mycobacteria species is very important to define treatment and it can be achieved by direct culture. However, the lack of clear protocols regarding the use of culture or molecular tests on specimens diagnosed with granulomatous lesions causes delays in the diagnosis of the etiological agents and, consequently, the definition of the right treatment.

The factors that determine the appearance of the different pathologic forms associated with bovine paratuberculosis are not fully understood, but new research suggests a critical role of innate immunity. Toll-like receptors (TLRs) trigger the recognition of invading pathogens by innate immune cells and the onset of specific immune responses. The aim of this work was to assess, immunohistochemically, the expression of TLR1, TLR2, TLR4, and TLR9 in intestinal samples of 20 cows showing different types of paratuberculous lesions: uninfected controls, focal lesions, paucibacillary, and multibacillary diffuse forms.

Free-living amoebae (FLA) are described as environmental reservoirs for some bacteria able to resist their phagocytosis. In the environment, the fate of Mycobacterium bovis (Mbo) and Mycobacterium avium subsp. paratuberculosis (Map), responsible for bovine tuberculosis and paratuberculosis respectively, remains poorly understood and is considered potentially problematic in the eradication and control of these diseases.
