Genotyping of Campylobacter spp

Article Abstract:

The various methods of genotyping Campylobacter species are described and their advantages and disadvantages are discussed. Fla typing is best for short-term limited-outbreaks but AFLP is best for global epidemiological studies.

Multilocus sequence typing for comparison of veterinary and human isolates of Campylobacter jejuni

Article Abstract:

Multilocus sequence typing (MLST) is applied to 266 Campylobacter jejuni isolates, mainly from veterinary sources, including cattle, sheep, pigs, pets, poultry and the environment as well as isolates from human cases of campylobacteriosis. The populations of veterinary and human isolates overlap, suggesting that most veterinary sources should be considered reservoirs of pathogenic campylobacter.

Evidence of genomic instability in Campylobacter jejuni isolated from poultry

Article Abstract:

Poultry isolates of Campylobacter jejuni, genotyped using pulsed-field gel electrophoresis (PFGE) of chromosomal DNA, were of clonal origin but had undergone genomic rearrangements. The diversity in PFGE banding patterns is believed to have originated from genomic rearrangements. For instance, there was an interesting variation in PFGE genotypes between isolates derived from one batch of poultry and these isolates were found to have identical fla genotypes and identical or similar Penner serotypes, biotypes and phage types.
