Parasitic Zoonosis Flashcards
Parasitic infection transmitted from animals to humans
Parasitic zoonosis
Disease cause by toxoplasma gondii
Toxoplasmosis
Primary host toxoplasma gondii
Cat
Intermediate host of toxoplasma gondii
Livestock
Route of transmission of toxoplasma gondii
Ingestion of oocyte from contaminated fod, water, soil with cat feces
Eating undercooked meat containg tissue cyst
Congenital transmission
A transmission of an infectious agent from a mother to her offspring during pregnancy or childbirth?
Congenital transmission
Clinical manifestations of toxoplasmosis in animals
Often asymptomatic
Severe cases: Neurologic issue, reproductive issue(miscarriage)
Clinical manifestations of toxoplasmosis in human
Mild flu like symptoms
Severe cases:Encephalitis
Ocular problem, miscarriage
Mild symptoms of toxoplasmosis in human
Flu like symptoms
Diagnosis for toxoplasmosis
Blood test
Polymerized chain reaction (pcr)
Prevention for toxoplasmosis
Cooked meat thoroughly
Practice good hygiene
Avoiding contact with cat feces
Causative agent of cysticercosis
Taenia solium
Defensive host of taenia solium
Human (adult tapeworm in small intestine)
Intermediate host of taenia solium
Pig (cysticerci in muscle)
Route of transmission of taenia solium
Ingestion of cysticerci from contaminated food/ water
Fecal oral transmission
mode of transmission where pathogens are spread through ingestion of contaminated food or water containing fecal matter?
Fecal -oral transmission
Clinical manifestations of cysticercosis
Neurocysticercosis (seizure, headache, neurologic issue)
Muscular cysticercosis
Ocular cysticercosis
Cyticerci in muscle tissue
Diagnosis for cysticercosis
Serological test
Meat inspection
Prevention cysticercosis
Human:
cook pork thoroughly
Good hygiene practice
Avoid fecal contamination
Animals:
Prevent access to humans feces
Ensuring proper sanitation
Causative agent of echinococcusis
Echinococcus granulosus
Echinococcus multilocularis
Definitive host of echinococcus granulosus & echinococcus multilocularis
Canids (dog, fox)
Intermediate host of E. granulosus & E. multilocularis
Livestock (pigs, goat, sheep, cattle)
Route of transmission of echinococcusis
Direct contact with infected canid feces
Ingestion of eggs from contaminated food, water, / soil.
Clinical manifestations of echinococcusis
Hydatid cyst primarily in liver and lungs
Cystic echinococcusis
Alveolar echinococcusis
Hydatid disease causes alveolar damage (alveolar echinococcusis)
Cystic echinococcusis
Diagnosis of echinococcusis
Imaging
Serological test
Biopsy
Prevention of echinococcusis
Safe disposal of animal offal
Proper hygiene
Regular deworming of dogs
Avoiding contact with stray dogs
Causative agent of strongyloidosis
Strongyloides stercoralis
Definitive of host strongyloides stercoralis
Human
T/F. Strongyloidosis primarily affect humans
TRUE
Route of transmission of strongyloidosis
Direct contact with soil contaminated by strongyloides larva
T/F. Transmission thru consumption is less common in strongyloidosis
TRUE
Clinical manifestations of strongyloidosis
Gastro intestinal symptoms (abdominal pain, diarrhea)
Coughing due to migration of larvae Respiratory failure
Diagnosis for strongyloidosis
Stool examination
Serological test
Fecal floatation
Prevention of strongyloidosis
Good hygiene practice
Proper sanitation and proper disposal of fecal matter
Regular deworming of livestock
