Survival Of Mycobacterium Avium Subspecies Paratuberculosis In The Pol
Mycobacterium avium subspecies paratuberculosis (map) is an intracellular pathogen that is known to parasitize macrophages and monocytes. Map infiltrates gastrointestinal tract host tissue where it is the known etiological agent of johne's disease in ruminants and implicated in the etiology of …

Survival strategies of Mycobacterium avium subsp. paratuberculosis in a variety of microenvironments.
… specifically Mycobacterium avium subsp. paratuberculosis (MAP), are extreme strategists and as a rule live by deception. Mycobacteria represent a group of closely related acid-fast bacilli that encompass a wide-range of host tropisms and diseases. Mycobacteria can be divided into two …

Evaluation of a Paratuberculosis Quantitative Polymerase Chain Reaction Assay with Microscopic Correlation
Paratuberculosis is an intestinal condition in ruminants infected with Mycobacterium avium subspecies paratuberculosis (MAP) and precedes Johne's disease, a chronic enteric disorder in ruminants caused by MAP infection. Necropsy with histopathology provides definitive diagnosis of Johne's disease …

Transmission Dynamics Of Mycobacterium Avium Subspecies Paratuberculosis In Closed Dairy Herds In The Us
… farm dynamics of Mycobacterium avium subsp paratuberculosis (MAP) infection on commercial US dairies. We focused on using deterministic mathematical models informed by molecular epidemiology and analysis of longitudinal data to evaluate current assumptions of MAP transmission. In vitro …

Age and Dose Dependent Susceptibility to Mycobacterium avium subspecies paratuberculosis Infection in Dairy Calves
Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne’s disease (JD), a chronic enteritis in ruminants. Control programs focus on prevention of infection of susceptible individuals: calves < 6 months of age. However, this age-cut-off for susceptibility is not well supported …

Phylogenetic Analysis of the Mycobacteria and Diagnosis of Paratuberculosis by 16SrRNA Amplification and Probing
… and M. intracellulare, the identification of M. paratuberculosis as a variant of M. avium, and could not distinguish the mycobacterium isolated from a Crohn's patient from the M. avium group. The 16S rRNA database served for the design of a series of group- and species-specific oligonucleotide …

A Hybrid Modeling Approach to Assess the Efficacy of Control Measures on Paratuberculosis on U.S. Dairy Farms
Paratuberculosis, also known as Johne's disease or JD, is a chronic contagious infection, caused by Mycobaterium avium paratuberculosis (MAP). This fatal disease is incurable and causes considerable economic losses to the industry. Each year, the U.S. dairy industry loses over 200 million dollars …

Creating a Marked Mycobacterium avium subsp. paratuberculosis Vaccine Strain and Detecting Marker-Specific Immune Responses in Calves
Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of Johne’s disease, a chronic, contagious granulomatous enteritis with a high global prevalence in dairy cattle. This disease causes significant economic loss in the dairy industry and has been challenging to control due to …

Establishment of a Long Term Cell Culture Model for Testing Anti-Infectives against Mycobacterium avium subsp. paratuberculosis
Mycobacterium avium subsp. paratuberculosis (MAP) is a very slow growing bacterium that is the causative agent of Johne's disease (JD) in ruminants and has long been suggested to be associated with complications of Crohn's disease (CD) in humans. Although there is no direct evidence that MAP is the …

Identification and validation of biomarkers for early diagnosis and resilience to bovine paratuberculosis using proteomics and immunohistochemical approaches
La Paratuberculosis bovina (PTB) es una enteritis granulomatosa crónica, causada por Mycobacterium avium subsp. paratuberculosis (Map), que afecta principalmente a los rumiantes. Esta enfermedad es especialmente relevante en regiones ganaderas, como Asturias (norte de España), debido a su impacto …

Isolamento e detecção molecular de Mycobacterium avium subespécie paratuberculosis (MAP) em rebanhos bovinos leiteiros na região de Viçosa - MG
… causada pelo Mycobacterium avium subespécie paratuberculosis (MAP), que acomete todos os ruminantes, caracterizada por síndrome de má absorção, diarréia e perda de peso. A doença tem grande importância econômica pela redução na produtividade, descarte prematuro de animais e aumento dos custos …

A FR 13 microbiological global risk model: demonstrated for pasteurization of raw milk with viable Mycobacterium avium subsp. paratuberculosis
… reduction of viable Mycobacterium avium subsp. paratuberculosis (MAP), a common bacterial contaminant and pathogen, is selected as an indicator of efficacy of process, and an inactivation model is then synthesized (Chandrakash and Davey, 2017 a). Results showed that for a design Regulatory …

Isolation, Characterization, And Application Of Novel Bacteriophages For Preventing Experimental Infection With Mycobacterium avium subspecies paratuberculosis (MAP) Of Dairy Calves
… disease is caused by Mycobacterium avium subsp. paratuberculosis (MAP) and primarily spreads to youngstock through the ingestion of contaminated feed and water. Due to JD's prolonged subclinical phase and the absence of a cure, conventional test-based culling has proven ineffective in curbing its …

Brucella abortus RB51 vaccine: Testing its Spectrum of Protective and Curative Characteristics
… BA infections. Mycobacterium avium subspecies paratuberculosis (MAP) causes paratuberculosis in ruminants. It is a slow growing intracellular parasite that requires CMI for its control, belongs to the genus Mycobacterium, and is closely related to M. avium avium (MA). Using RB51 as a vector …

Real Time RT-PCR for Direct Detection of Viable Mycobacterium Avium Subspecies paratuberculosis in Chron's Disease Patients and Association of Map Infection with Downregulation in Interferon-Gamma Receptor (INFG1) Gene in Crohn's Disease Patients
Association of Mycobacterium avium subspecies paratuberculosis (MAP) with Crohn's disease (CD) and not with ulcerative colitis (UC), two forms of inflammatory bowel disease (IBD), has been vigorously debated in recent years. This theory has been strengthened by recent culture of MAP from breast …
