Question

Fecal samples collected from small animals using the ______ collecting method should be used for direct examination only because of the amount collected this way.

1) Fecal loop
2) Gloved-finger
3) Owner-bagged
4) Jarred

Answer 1

The fecal loop is the correct method for collecting small samples of feces, used solely for direct examination due to the limited amount collected.

Step-by-step explanation:

The correct answer to the question is 1) Fecal loop. The fecal loop collecting method gathers a small amount of fecal material for direct microscopic examination. Due to the minimal quantity collected using this technique, it is only suitable for direct examination rather than more complex analysis methods that require larger sample sizes.

Direct examination of fecal specimens is an essential diagnostic tool for various intestinal parasites and infections. Although microscopic analysis is helpful, additional testing methods such as immunoassay and molecular approaches like PCR (Polymerase Chain Reaction) offer more specific diagnoses. For certain parasites, multiple samples collected over several days are recommended for accurate detection.
