-Collect 1 tbsp(onlt 1 tsp needed) -Use plastic gloves or device -Keep fecals sealed -Keep fecals refrigerated -Do not use tissue, paper towels or paper cups to store fecals -Label all samples -Note species |
|
A vet techs role in handling fecals
|
-Keep good records
-Keep a lab log -Label all samples -Use gloves -Clean and wash immediately |
|
What to look for in a gross examination of fecals
|
-Color
-Consistancy -Parasites(roundworms and tapeworms can be seen) -Blood (what color) -Mucus -Foreign materials -Age of fecals |
|
How to use the microscope in examining fecals
|
-Use 10x scan for all fecals
-Go up to 40x for protozoans -count the number of ova/larva seen + few ova seen (rare) ++ between few and 1 field +++ 1=/feild (many) - Negative for parasites -Scan all fields of veiw -Go back to review the edges of the coverslip |
|
Types of flotaions solutions
|
-Sodium nitrate,NaNo3(most popular)
-Zinc sulfate, znSO4 -Sugar(sheather's solution) won't destroy fragile eggs -Magnesium Sulfate, MgSO4 Epsom salt -Saturated sodium chloride, Nacl (table salt) |
|
Pros and Cons for Sodium Nitrate
|
PROS
-commercially available -effecient in floating ova, even trematodes CONS -can be expensive -forms crystals and air bubbles -can distort ova over >20 min -floats debris |
|
Pros and cons for Zinc Sulfate
|
PROS
-floats protozoan organisms with the least amount of distortion CONS -may distort helminths |
|
Pros and Cons of sugar solution
|
PROS
-does not distort helminths -does not crystalize inexpensive -long self life CONS -sticky -ova rise slowly may distort fraglie larva tramatodes or cysts -attracts bugs |
|
CAPC guidelines for parasite control and treatment
|
-Pracitce good personal hygiene
-Control pet parasites infections through internal and external parasite tx and control -Minimize exposure of children to potentially contaminated enviroments -Clean up pet feces regularly to reduce enviromental contamination -Understand and communicate parasitic infection risks and effective control measures -Consider pet health and lifestyle -Lifelong prevention of common parasites -Enviromental control of parasites -Staff, pet owner and community education -Owner consideration in preventing zoonotic diseases |
|
Puppy and kitten treatment control
when to start treating puppys and kittens |
Tx of puppies:
2,4,6,8 weeks of age then put on monthly preventative Tx of kittens 3,5,7,9 weeks of age then put on montly prevenative |
|
What is the proper way to classify a parasite
|
Common name: Roundworm
Kingdom: Animalia Phylum: Nematoda Order: Ascaridia Genus: Toxocara Species: Cati |
|
How are parasite usually reported?
|
-Classification
-Hosts -Life cycle -Pathogenicity -Zoonotic significance -Signs and symptoms -Treatment -Prevention |
|
What are Three types of parasites?
|
Parasite- An organism which lives on(ectoparasite) or in(endoparasite) another living organism (host) at whose expense it obtains some advantage
Erratic or Aberrant Parasite- An organism which wanders from its usual site of infection Free-living parasite- An organism which is capable of living in the enviroment and leading a non parasitic existance |
|
What are Four types of hosts?
|
Definitive host- a host that harbors the adult, sexually mature stages of a parasite, usually defined as the final host
Intermediate host- This host harbors at least on developmental stage of the parasite before trasferrign it to another host(Without this host the parasite would not exsist) Parentenic host- This host harbors a stage of the parasite which does not undergo a developmental stage(ex.a mouse) Resivoir host- a vertabrate host in which a parasite or disease occures naturally and is a sourse of infection( ex. A dog who is harboring heartworm is carrying the infection and could expose it to any mosquito(untermediate host) that bites it) |
|
What is a carrier host?
|
some resivoir hosts act as carrier hosts. That means that they carry the parasites but they show no signs of illness
