Principles of Nematology


LNT MAN


I. Methods of collecting nematodes (Cattle)

A. Destroy the animal by shooting or otherwise.

1. Open up abdominal and thoracic cavity.

a. Tie off abomasum at pyloric and cardiac ends.

b. Tie off small intestine at stomach and ileo cecal opening.

c. Tie off large intesting at ileo cecal and rectal ends.

d. Remove entire viscera to a clean tub or other container.

e. Make careful check for any parasites in abdominal cavity. Preserve

and label same if found.

2. Examine the following organs for parasites, preserve and label accord-

ingly.

a. Paunch (rumen), heart, liver, kidneys, lungs and lymph glands

3. Take entire viscera to laboratory.
a. Open abomasum (stomach) in large dish.

b. Empty contents into measured dish, note and record condition.

c. Wash, knead and scrape to remove any adhering parasites.

d. It is important not to use any more water than necessary to thorough-

ly wash organ. Pour washings into container with contents.

e. Add water to contents to the 2000 cc. or 4000 cc. mark or your

preferred factor.

(1) Agitate taking care not to whirl washings and take ten (10)

factor samples.

(2) Identify each sample by proper labels and add an equal volume

of 95% alcohol to each sample for storage, or examine imnedi-






2 -

ately for microscopic parasites.

f. Screen balance of material for macroscopic parasites.

(1) Identify, label and record on chart.

4. Open entire small intestine and work as per abomasum (3a through 3f).

a. Count nodular lesions and record same,

5. Open large intestine using all the water necessary to thoroughly wash

same, screen for macroscopic parasites, identify, label and record on

chart. Count nodular lesions and record same.

6. Record all parasites on proper form.

II. Methods of preserving

A. Nematodes are best killed in steaming hot 70% alcohol or in hot 5% to 10%

formalin. They are preserved in the same solutions. Later, a few drops of

glycerine may be added. If other killing solutions are used they should be

hot (unless the worms are unusually delicate) since the heat causes the

worms to straighten.

1. Preserving solution (Parasite Laboratory)

a. Distilled H O 280 cc.
90% Alcohol 140 cc.
Formalin 42 cc.
Gl. Acetic Acid 7 cc.
Mix

III Life cycles vary greatly. As a rule the embryo or larva molts or sheds its

cuticula four times before it becomes adult. The resulting larvae are called

the 1st, 2nd, 3rd, and 4th-stage larvae. Larvae never reproduce* The second

ecdysis or molt is important because only after this molt are the larvae in-

fective. That is, the 3rd-stage larva is the infective larva. In some cases,

as in hookworm larvae, the second molt is not complete for some time and the

old cuticula loosely surrounds the larva like a sheath. The infective stage may

be reached within the egg as in Ascaris and Enterobius. Usually two molts oc-

cur within the final host. Infection with nematodes may result from ingesting






-3-
infective eggs, by ingesting an intermediate host containing infective larvae,

by skin penetration by larvae from water or soil, or from a biting insect.

The most common means of infection, however, in domestic animals, is for the

animal to consume the infective larvae in or on contaminated food or water.
