paratuberculosis/hypoxia

Mycobacterium avium subsp. paratuberculosis is an important pathogen that causes Johne's disease in animals and has been implicated in Crohn's disease in man yet few data exist on its physiological adaptation in either the host or the environment. In this study, the proteomic responses of the two

The aim of this study was to assess the immunogenicity of recombinant stress-associated proteins of Mycobacterium avium subsp. paratuberculosis in sheep infected with the organism compared to control sheep. Five proteins - MAP2411, ClpP, Ppa, MAP0593c and GreA - which were identified previously in

The growth pattern and protein expression profiles of sheep (S) and cattle (C) strains of Mycobacterium avium subsp. paratuberculosis (MAP) under oxidative and nitrosative stress were characterised. Oxidative stress was induced using 0.05% (v/v) H(2)O(2) in BACTEC medium, and was lethal for an

Mycobacteria are able to enter into a state of non-replication or dormancy, which may result in their chronic persistence in soil, aquatic environments, and permissive hosts. Stresses such as nutrient deprivation and hypoxia provide environmental cues to enter a persistent state; however, a clear

Mycobacterium avium subspecies paratuberculosis (MAP) is the causative pathogen of Johne's disease in ruminants, characterized by chronic granulomatous enteritis; it also has zoonotic potential and is associated with Crohn's disease in humans. A better understanding of the mycobacterial antigens and
