Epithelial Cells (urine)

Young baby stage of fleas have a long body with tons of hairy legs. At this stage looks like hair.

Flea Larvae (Genus Ctenocephalides)

Defined circles tightly packed together

Flea Tapeworm Egg (Genus Dipylidium)

- tapeworm, segments full of egg capsules are shed through the animal's feces.

- egg capsules are ingested by flea larvae, where the eggs hatch and begin to mature inside the larvae

- the infested flea is ingested by the animal.

- tapeworm develops into an adult in the animal's intestines, as the flea is ingested it attaches to the intestinal lining and feeds on the animal's tissue.

- when the tapeworm fully matures, it begins to shed segments of its body off, which end up in the animal species repeating the cycle

Flea tapeworm segment (Genus Dipylidium)

Long worm with defined segments, the segments will be circular, and the skullex or head will look like it has a little ball of hair on top.And will have two big circles.

Flea Tapewor. (Genus Dipylidium)

-Large body with long legs for jumping from animal to animal

-brown in color.

Fleas (Genus Ctenocephalides)

-Infectious protozoa that swims in the small intestine

-looks like a teardrop with the face in long flagella

Giardia (Genus Giardia)

Angel hair pasta very long and thin.

Heartworm Adult (Genus Dirofilaria)

- immature, heartworm found in blood smears.

- thin long worm in blood, often blue or purple because of the stain

- will only be seen under a microscope.

Heartworm Microfilaria (Genus Dirofilaria)

- the size of a staple and thin

- under a microscope, you can see the esophagus the mouth will have little fangs or hooks

- Can look like a small staples when not under a microscope

Hookworm Adult

Defined cell membrane, inside the cell is blobby with no defined shapes, can look like 4 big blobs smushed together.

Hookworm Egg

- Found attached to horse hair

- bots are small and have defined ridges of the bones.

- The eggs are laid towards the end of the hair with only one egg per hair.

- Adults will look like a wasp or a bee

Horse Bots (Genus Gasterophilus)

- type of hookworm

- have a red and purple hue.Due to ingesting horse blood

- the sides of a staple in the mouth looks like a fishbowl the tail comes to a small whip.

- when looking at an egg, look at the space between the inside matter and the cell membrane

- they can be seen in fecal matter

Horse Strongylss (Family Strongylidae: Genus Strongylus)

- Mouthpiece is large in square for biting

- Eggs are found on hair and will attach to the bottom of the egg

Lice- Biting

- Mouthpiece forms a point or spear to reach small blood vessels in the skin

- Eggs attach the length of the egg to the hair

Lice- sucking

- Flat parasite that attaches to the liver

- eggs are oval and will have only one cap

Liver Fluke

Its a mosquito

Mosquito Adult

- Large head and eyes, long hair and body

- can be found in areas of water with little or no flow.

Mosquito larva

- Nucleus has many lobes, often five cytoplasm has a neutral color

- the nucleus is significantly darker than the rest

Neutrophils

- small, colorless cell fragments in the blood that help stop bleeding. And form clots.

- typically relatively round in shape

Platelets

Type of blood cell that transport oxygen and nutrients throughout the body

Red blood cell (Erythocyte)

Rod shaped bacteria are called bacilli, and they have been found in many groups

Rod (bacteria)

- Can sometimes be observed in a dog's feces or vomit

- mouthpiece has three parts and “wings” on the side of the head

Roundworm adult

- infected dog shed through their stool

- larvae, develop inside the eggs, 2-4 weeks later, making them infectious to another dog

- after ingesting larvae migrate through the walls of the intestines liver and lungs

- egg is round with distinct inside and lighter shell and can only be seen under a microscope

Roundworm egg

- also called scabies is an itchy disease in dogs caused by a mite

- small and not visible to the naked eye

- burrow into the skin and cause itching redness and skin crust.At the tip of the ear's elbows, hawks, chest and belly

- legs are shorter than the body

Sarcopotic Mite

- Also known as triple phosphate or magnesium ammonium phosphate

- a common cause urinary track stones in dogs and cats

Struvite Crystals (Triple magnesium phosphate)

- tiny round egg with a thick shell that comes from a type of tapeworm found in animals like cows and pigs.

- animals can swallow these eggs which then grow into larvae and can grow into adult tapeworms in their intestines.

Taenia Tapeworm Egg (Family Taeniidae: Genus Taenia)

- a rectangular shaped segment of the tapeworm.

- segment is wider often it's long

Taenia tapeworm segment

- parasitic worms that affect animals as hosts

- they use animals to complete their life.Cycle often causing diseases like taniasis or cystucercpsis

Taenia Tapeworm (Family Taeniideae; Genus Taenia)

Short mouthpiece scutum has very distinct patterns

Tick- American dog

Long mouthpiece scutum has legs and will be darker than the body

Tick- Black legged Deer

Short mouthpiece, long body scutum will be pure brown

Tick- brown dog

Long mouthpiece, scutum of the female will have a defined white dot, males will have a pattern similar to American dog just black rather than white

Tick- lonestar

- oval shaped with a thick shell and have a distinct caps or plug like structures at both ends

- typically, light browned in very resilient, capable of surviving in the environment for extended periods until ingested by a host where they hatch and develop into adults

Whipworm egg (Genus Trichuris)

- reside in the large intestine of animals

- named for their whip, like shape with a long slender anterior and a thicker prosterior end

- adults tend to be white or reddish brown.

- the anterior end embeds into the intestinal lining to feed on blood and tissue fluids, while the thicker tail end remains free

Whipworm (Genus Truchuris)

- single cell fungi that can be commonly associated with conditions like infections or skin issues in the animal

- thrive in warm, moist environments and are extremely small in microscopes

Yeast (cytology)
