Lack of evidence for vertical transmission of Campylobacter spp. in chickens
Article Abstract:
A major cause of bacterial food-borne infection, 'Campylobacter jejuni' (C. jejuni) is present in eggs and hatchery fluff and it is possible that the bacteria could vertically transmit from hens to progeny. A study to verify this was conducted in Iceland where only eggs imported from grandparent flocks in Sweden are used to establish breeding stocks minimizing the chances of horizontal transmission of isolates and the results supported the possibility of vertical transmission.

Role of Campylobacter jejuni flagella as colonization factors for three-day-old chicks: analysis with flagellar mutants
Article Abstract:
The role of Campylobacter jejuni flagella on the ability of the bacterium to colonize the chicken gastrointestinal tract was studied. The flagellar genes of C. jejuni IN9 was disrupted to produce mutants either lacking flagella or with altered flagella. These mutants were then tested for the ability to colonize the 3-day-old chick by oral challenge with different doses. The results show that Campylobacter flagella are important colonization factors in chickens.

Competitive exclusion of heterologous Campylobacter spp. in chicks
Article Abstract:
Campylobacter jejuni strains from chickens can outcompete human strains when given orally to young chicks. This indicates that the use of genetically modified C. jejuni strains could be used as probiotics to prevent the colonization of chickens with human strains.
