Techniques used to identify parasites, categorized as visual identification and non-visual tests.

Diagnosing parasites by physically examining samples like blood, feces, urine, or tissue sections using stains/procedures like Giemsa or McMaster.

Techniques like fecal antigen tests, PCR, or serology that don't directly visualize the parasite.

Qualitative tests detect the presence or absence of a parasite, while quantitative tests measure the number of parasites present.

A diagnostic test used to identify parasites in fecal matter.

Proper methods for collecting, preserving, and submitting parasite specimens.

Recognition of the risk of infection from parasitological samples.

Fresh samples are ideal for parasite diagnostics but freezing/preservatives are necessary if fresh aren't possible.

Methods to find parasitic protozoa (like Trypanosoma and Babesia) and nematode larvae (microfilariae) in blood samples.

Giemsa stain is commonly used to visually detect parasites in blood samples.

Symptoms like anemia, fever, lethargy, or exposure to ectoparasites can indicate blood parasites.

Methods to identify parasites in fecal samples to diagnose intestinal infections.

Direct mounts, flotation, sedimentation, Baermann, and McMaster techniques help find parasites in feces.

Fecal loops should not be used for parasite detection.

Cytauxzoon felis, a parasite, is transmitted by ticks.

Differentiating between Dirofilaria immitis and Acanthocheilonema reconditum in blood samples.

A method used to identify protozoa, cysts, oocysts, and some larvae in fresh feces.

Separates eggs/cysts by density; a high-specific gravity solution sinks heavier materials.

A solution with high specific gravity for flotation.

Eggs/cysts float by specific gravity, no special procedures.

Separating eggs of trematodes (flukes) by letting solids settle.

Used to recover trematode eggs by allowing them to be washed through a liquid.

Density of a substance compared to water. Used in flotation solutions.

Single-celled organisms, stages of their lifecycle, and other pathogens identified in fecal analysis.

Methods to estimate the level of parasite infection, not just the presence.

A fecal flotation diagnostic method, ideal for horses and ruminants.

More precise parasite level measurement when egg per gram (EPG) counts are high.

Treating only animals that have high parasite counts.

Assessing the success of parasite control measures.

A method to find small ectoparasites (e.g., mites).

Parasite identification methods that don't rely on looking at the parasite's shape.
