The Development Of New Molecular Tools To Detect Mycobacterium Avium Subspecies Paratuberculosis From A Bovine Faecal Environment By Real-Time Pcr, Marcel De Kruijf

Theses

The slow-growing intracellular pathogen Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne’s disease in domesticated and wild ruminants. Johne’s disease inflicts severe annual economic losses to the dairy industry worldwide. This thesis is divided into five chapters that consist of a literature review' chapter and four experimental chapters focusing on MAP strain genotyping and the development of novel molecular MAP detection tools using real-time PCR. Chapter 1 describes published information regarding MAP characteristics, Johne’s disease, MAP genomes, available MAP detection methods, MAP epidemiology and genotyping.

To efficiently control and monitor MAP infection, molecular t>ping of MAP strains provides extensive knowledge …

An Investigation Of The Use Of Natural Agents To Control Mycobacteria, Olga Lesniak

Theses

Economic losses that are caused by Mycobacterium avium paratuberculosis (MAP) infections represent a major obstacle for farmers and also for the dairy industry. In order to control the population of MAP, alternative control agents must be investigated. One of the studies described in this thesis focused on using a bacteriophage therapy based approach to assess its efficacy on simulated industrial environments and food models. Another study described in this thesis investigated the antimicrobial effects of parsley and garlic on a range of mycobacteria species. Both studies used conventional microbiological methods such as plaque assays, AlamarBlue assay (MABA) and growth curves, …
