Diseases Caused by Parasites Flashcards
Helminths/Worms
- ASCARIS SUUM
- OXYURIS EQUI
- FASCIOLA HEPATICA and FASCIOLA GIGANTICA
- SCHISTOSOMA JAPONICUM
- TAENIA SAGINATA
- TAENIA SOLIUM
- A nematode (roundworm)
- The larvae of this parasite migrate into the lungs and liver thus eliciting inflammatory response
- As adults, these worms reduce feed efficiency
- In heavy infections, it causes emaciation to the animal
ASCARIS SUUM
Host of Ascaris Suum
PIGS
Pin worm belonging to nematodes
OXYURIS EQUI
Host of Oxyuris Equi
HORSE
Lay their eggs by cementing them to the perineum around the anus
ADULT FEMALE PIN WORM
Common name of Fasciola hepatica and Fasciola gigantica
COMMON LIVER FLUKE
Are classified as trematodes
FLUKES
Final host of Fasciola hepatica
RUMINANTS
Causes liver cirrhosis in cattle; in sheep it is in conjunction with infectious necrotic hepatitis or “black disease” which is often fatal
FASCIOLA HEPATICA
- This fluke stays in the blood vessels of the liver, the portal vein
- Causes ascites, emaciation of the animal, fibrosis of the liver parenchyma thus causing cirrhosis
- A trematode
- Zoonotic
SCHISTOSOMA JAPONICUM
Final host of Schistosoma Japonicum
RUMINANTS
Intermediate host of Schistosoma Japonicum
SNAIL (ONCOMELANIA QUADRASII)
Endemic in Eastern Leyte, Samar and Surigao
SCHISTOSOMA JAPONICUM
- Adult cestode (tapeworm)
- The larval cyst can be found in the heart, tounger, diaphragm and jaw muscles
TAENIA SAGINATA
Final host of Taenia Saginata
HUMAN
Intermediate host of Taenia Saginata
RUMINANTS
Formerly known as Measly beef, a larvae of Taenia Saginata that encyst on muscles of beef cattle
CYSTICERUS BOVIS
- Another cestode whose final host are humans
- Larval cyst can be found in the same areas as the previous worm
TAENIA SOLIUM
Intermediate host of Taenia Solium
PIG
Larvae of Taenia Solium that causes measly pork
CYSTICERUS CELLULOSAE
Protozoans
- COCCIDIANS
- TOXOPLASMA GONDII
- TRITRICHOMONAS FOETUS
- TRYPANOSOMA EVANSII
- These belong to either genus Eimeria and Isospora
- Host varies from poultry to livestock to companion animals
COCCIDIANS
Found in the ceca of poultry known to provide a big losses in the poultry
EIMERIA TENELLA
This protozoan causes abortion to all species of mammals including humans
TOXOPLASMA GONDII
Natural host of Toxoplasma Gondii
CATS
- A venereal disease in cattle
- Causes infertility to bulls and early gestational (pregnancy) abortion in pregnant cows
TRITRICHOMONAS FOETUS
Old name of Tritrichomonas Foetus
TRICHOMONAS FOETUS
- Causative agent to Surra
- Fatal to horses and camels
TRYPANOSOMA EVANSII
Vector (carries of the protozoan) of Trypanosoma Evansii
TABANUS SPP (HORSE FLY)
- Causative agent of Sarcoptic Mange or kurikong in Cebuano

SARCOPTES SCABEI
- Causative agent of Demodectic Mange
- Known as Galis in Filipino
DEMODEX SPP.
- Causative agent of Psoroptic Mange
- Commonly seen in rabbits, cattle and sheep
PSOROPTES SPP.
- Causative agent of Otodectic Mange
- Commonly known as ear mite
