Endoparasites live inside the host. The may either be microparasites such as: blood protozoans (Theileria, Babesia, Trypanosomes) or macroparasites like: Helminths (Trematodes, Cestodes, Nematodes).
Several types of nematodes or roundworms can infect cattle. Although there are many species of worm parasites harbored in the gastrointestinal tract of cattle, only a few target species are clinically and economically important. Strongyloides papillosus is found in the small intestine. Cattle become infected by transmammary, transcutaneous, and oral routes of larval acquisition. Adult roundworms do not multiply in the cattle host. The eggs must pass into the environment to continue the parasite life cycle. The adult life span is only a few months. In order to diagnose a roundworm infection fecal samples were analyzed.
Dung samples were collected from cows with the following symptoms: Green diarrhoea. rough coat, dehydration, reduced milk productivity etc. Sedimentation technique was carried out in order to collect the eggs. The protocol is as follows:
The eggs of Strongyloides were observed to be: (figure 1)
