Pictures of parasitic nematodes in chicken found by students
Here a selection of photo’s are shown of parasitic nematodes that were found in the digestive system of chicken.
Most pronounced morphological characteristics of these nematodes include body length, male and female reproductive organs and there position. Besides, the organ or part of the chicken’s digestive system in which the nematodes are found can be indicative for which nematode species was found.
Ultimate proof on species level can be obtained by sequencing the 18S Short SubUnit (SSU) of the nematode’s ribosomal DNA, or digestion pattern of this DNA fragment with discriminating restriction enzymes.
