Assistant Laboratory Animal Technician (ALAT) Practice Exam

Which of the following are signs that an animal may have parasites?

1. Increased appetite and weight gain

2. Diarrhea, vomiting, and anemia

3. Excessive grooming and playfulness

4. Fever and lethargy

The correct answer is: Diarrhea, vomiting, and anemia

Diarrhea, vomiting, and anemia are common signs indicating that an animal may have parasites. Parasitic infections often disrupt the host's normal digestive processes, leading to gastrointestinal issues such as diarrhea and vomiting. Additionally, parasites can consume the nutrients intended for the animal, resulting in anemia due to blood loss or malnutrition. These clinical signs serve as red flags for harboring parasites, making them critical indicators for diagnosis and further veterinary evaluation. While increased appetite and weight gain, excessive grooming and playfulness, and fever and lethargy might be associated with various health issues, they are not as directly correlated with parasitic infections as the signs listed in the correct option.
