Later observers have found similar occurrences in the cases of small nematodes, rotifers and bacteria.
Orders: Nematodes Lumbricini and Branchiati.
The so-called eelworms (Nematodes) may do immense damage on roots and in the grains of cereals, and every one knows how predatory slugs and snails are.
Nodules due to eel-worms (Nematodes) are produced on numerous classes of plants, and frequently result in great losses-e.g.
The parasitic Nematodes include by far the greatest number of the known genera; they are found in nearly all the orders of the animal kingdom, but more especially among the Vertebrata, and of these the Mammalia are infested by a greater variety than any of the other groups.
