NEW parasitology exam flashcards 1,2,3

The reason for why we study parasitology

To promote public health, food safety, environmental health, prevent disease in animals, prevent and control zoonotic disease, and human animal bond.

The reason for why we use the Linnaean classification system

We use it so we are all talking about the same thing

Veterinary client patient relationship (VCPR) definition

The veterinarian-client-patient relationship (VCPR) is the basis for interaction between veterinarians, their clients, and their
patients and is critical to the health of the animal.

Important things in the VCPR

The vet and client are in agreement, The vet has seen the patient in the last year, The vet is readily available for follow up evaluation, and records are maintained.

The 5 kingdoms

Plantae, Animalia, Protista, Monera (Eubacteria and Archaebacteria), Fungi

The 2 kingdoms of interest in vet medicine

Animalia, and Protista

The phylum of interest in the Kingdom of Animalia

Platyhelminths (Flatworms), Nematoda (Roundworms), and Arthropoda.

Helminths

The worms- the platyhelminths and the nematodes

Nematodes are known as what

Roundworms

The amount of developmental stages larvae have

5

Nematode identification

Based on their type of egg or larval stage

Oviparous eggs

Ascaroid or ascarid, Trichinelloid or trichuroid, Trichostrongyle(Morula)

Ovoviviparous egg name

Spiruroid or spiruria

Larviparous (Larvel stages)

Microfilariae(pre larval), Lungworm(Kinked tail), Dracunculoid(long-tailed larvae)

Rule for larval stage

The 3rd larval stage is the infective stage

Platyhelminths

Flatworms

Class Trematoda is called

Flukes

Class Cestoda is called

Tapeworms

Subclass Eucestoda is called

true tapeworms

Subclass Cotyloda is called

pseudo tapeworms

Flukeworm Image

Flat, leaf shaped

ribbon-like

The reason why arthropods are problematic (includes mites, ticks, and insects)

They directly threaten human health, food security, and infrastructure through their evolutionary resilience.

Casual agents (why arthropods are problems)

Flea anemia, saracoptic manage

Intermediate host (why arthropods are problematic)

For helminths and protozoans

Vectors (why arthropods are a problem)

Bacteria, viruses, spirochetes, Rickettsiae, chlamydial, other

Flagellates

Move using flagella (Giardia)

Amoebae

Move using pseudopodia (Entamoeba)

Apicomplexans

Non motile adults use apical complex to invade cells (Coccidia)

Ciliates

Move using cilia (Balantidium)

These phyla are based on

locomotion

Big or Tiny (Protozoa)

Tiny

Life cycle stages

Switch between active breeding

Protozoa

microscopic, single-celledliving things that have a nucleus and act like tiny animals

Symbiont

2 organisms of different species in a relationship

5 types of symbiosis

Predator-prey, phoresis, mutualism, commensalism, parasitism

Insecticides treat this

Arthropoda (All insects, mosquitos, fleas, flies etc,

Antihelmintics treat this

Nematodes and platyhelminths (roundworm, tapeworm, flukes, thorny head worms)

Acaricides treat this

Arthropoda (mites, ticks)

Antiprotozoals

Protozoa (Coccodia, Giarda)

Most succeptible to get parasitic infections

Children and elderly
