Mycobacterium avium subsp. paratuberculosis: pathogen, pathogenesis and diagnosis.
Johne's disease, or paratuberculosis, is a chronic intestinal infection caused by Mycobacterium avium subsp. paratuberculosis. The usually fatal disease is characterised by cachexia, and in some species diarrhoea, after a long pre-clinical phase. Treatment is ineffective and economically impracticable. The infection primarily affects domestic and free-ranging ruminants, but has also been report...
متن کاملFatal mycobacteriosis with hepatosplenomegaly in a young dog due to Mycobacterium avium.
Cases of disseminated Mycobacterium avium infections in dogs are rare because it appears that the species is innately resistant to infection. A 2-year-old, castrated, 5 kg Shih Tzu-Poodle-cross developed anemia, abdominal pain, lethargy, and splenomegaly. Histological examination of surgically removed spleen indicated marked granulomatous splenitis with myriad intracytoplasmic acid-fast bacteri...
متن کاملMycobacterium avium avium and Mycobacterium avium hominissuis give different cytokine responses after in vitro stimulation of human blood mononuclear cells
Background: Mycobacterium avium is the principal etiologic agent of non-tuberculous lymphadenitis in children. It is also a known pathogen for birds and other animals. Genetic typing of M. avium isolates has led to a proposal to expand the set of subspecies to include M. avium subsp. hominissuis. Isolates associated with disease in humans belong to this subspecies. Methodology/Principal Finding...
متن کاملDifferential responses of bovine macrophages to Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium.
Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium are antigenically and genetically similar organisms; however, they differ in their virulence for cattle. M. avium subsp. paratuberculosis causes a chronic intestinal infection leading to a chronic wasting disease termed paratuberculosis or Johne's disease, whereas M. avium subsp. avium causes only a transient infec...
متن کاملMycobacterium Avium Complex
These two species are difficult to differentiate and therefore they are also referred to collectively as Mycobacterium avium-intracellulare (MAI) . Although it might more logically be termed the Mycobacterium avium-intracellulare complex such nomenclature has not been adopted. They are both opportunistic pathogens that affect the immunocompromised, particularly HIV-positive individuals. They ca...
