Insertion sequence fingerprinting and transpositonal activity in mycobacteria by N"Dingsa G. Fomukong Download PDF EPUB FB2
Mycobacteria differ so strongly from other bacteria in their cell wall architecture and metabolism that they require specific diagnostic tests, i.e.
stains, culture media, identification methods. Tuberculosis and leprosy are well-known diseases of mankind, but Buruli ulcer disease and nontuberculous mycobacterial diseases are gaining recognition as important diseases in specific settings.
The sequence of three independent copies have been determined and these were virtually identical, differing in only a few base pairs.

Dec; (24)– [PMC free article] Collins DM, Stephens DM. Identification of an insertion sequence, IS, in Mycobacterium bovis. FEMS Microbiol Lett. Sep 15; 67 (1)–Cited by: An insertion sequence-like element, IS, was isolated from a Mycobacterium tuberculosis cosmid library as a repetitive sequence.
IS shows similarities with elements of the IS3 family. This insertion sequence was found to be specific to mycobacteria belonging to the M. tuberculosis by: V 57 12 tinental flight. Non-tuberculous mycobacteria can be transmitted in raw milk or insufficiently heat-treated meat.
Water and soil are frequent sources of mycobacterial infections either in the form of direct contacts for aquarists or gardeners or by means of aerosols in showers or indoor swimming by: For rapidly growing mycobacteria (RGM), the KDa heat shock protein and RNA polymerase Beta subunit genes are more variable than the 16S rRNA gene, making these targets useful in the discrimiation of closely related species such as M.
abscessus, M. Isolation of mycobacteria and their identification based on phenotypical manifestations, particular-ly culture, has been constantly used as a “golden standard” (Taylor et al., ). Due to the fact that these methods are much more time consuming, their use is on the decline.
They have been replaced by methods based on DNA detection. In tuberculosis, it is often important to establish the source of infection and to determine whether disease is due to a new strain of Mycobacterium tuberculosis or to relapse.
To cope with the resurgence of tuberculosis and atypical mycobacterioses in AIDS patients, on the one hand, and to overcome the limitations of classical bacteriological procedures on the other, the development of rapid Cited by: Semi, H., Bottger, E C, and VilJanen, M K () Identification of mycobacteria by PCR-based sequence determination of a kilodalton protein gene J Clin Mxrob – Google Scholar by: Summary.
An insertion sequence, IS, in the genome of Mycobacterium bovis has been identified and sequenced. It is bp long with 15 bp inverted repeat ends and contains a large ORF.
There are six copies of IS in the genome of M. bovis and the element is also present in Mycobacterium is not closely related to other DNA elements described in Cited by: Katoch V M. DNA fingerprinting of Mycobacterium tuberculosis isolates from Agra region by is probe.
Indian J Med Microbiol [serial online] [cited Oct 7 ]; Mycobacterium is a genus of Actinobacteria, given its own family, the species are recognized in this genus. This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis (Mycobacterium tuberculosis) and leprosy (Mycobacterium leprae) in humans.
The Greek prefix myco-means "fungus," alluding to the way mycobacteria have been Domain: Bacteria. “Molecular Genetics of Mycobacteria is an extraordinary book. It includes chapters from virtually every major scientific contributor to the genetic understanding of mycobacteria.
For anyone entering the field or seeking to learn about fundamental genetic and molecular aspects of mycobacteria, this book 5/5(2).
The Ziehl-Neelsen staining for the direct detection of mycobacteria by microscopy is used to identify acid fast bacilli. The lipid rich cell wall of mycobacteria makes it resistant to Gram stain. It can also be used to stain few other bacteria like Nocardia. The reagents used for the staining are carbolfuchsin, acid-alcohol and methylene blue.
Different subtypes of Mycobacterium tuberculosis (MTB) may induce diverse severe human infections, and some of their symptoms are similar to other pathogenes, e.g. Nontuberculosis mycobacteria (NTM). So determination of mycobacterium subtypes facilitates the effective control of MTB infection and proliferation.
This study exploits a novel DNA barcoding visualization method for Cited by: 2. INTRODUCTION. Mycobacterial species other than Mycobacterium tuberculosis and Mycobacterium leprae are generally free-living organisms that are ubiquitous in the environment.

The prevalence of lung disease due to infections with nontuberculous mycobacteria (NTM) has been increasing and surpassed tuberculosis (TB) in some countries. Treatment outcomes are often unsatisfactory, highlighting an urgent need for new anti-NTM medications.

The goal of this module is to discuss the classical and emerging methods for identification of mycobacteria, advantages and limitations of the different methods, importance of quality, accurate identification results, clinical significance of mycobacteria, turnaround times and reporting considerations,File Size: 2MB.
This technique is particularly useful to identify mycobacteria species for which nucleic acid probes are unavailable, including rapid-growing mycobacteria species of the M. fortuitum-chelonae group.
