to explain it you can see the biologicals cycles of this nematode and for the donkeys. after that you do approximation of these

The epidemiological significance is that there are mixed infections which could either boost and negatively impact the immune system of the donkey. The significance can be better understood depending on the immunomodulatory effect of these worms in donkeys. Howbeit, the public health significance is also very important, since donkeys are often used by humans in those areas. You may want to know if some of these worms are zoonotic. It is also important to know the infective stages of these worms and how they impact the life of the animal in question. It's an interesting finding that could be broadly explained. You may also want to conduct some molecular studies on the worms.

Thank you for the great contribution @Paul Odeniran
