What is parasitic pharyngitis?
Infection with adult fasciola due to ingestion of infected raw liver
What are the two organisms that cause pharyngeal fascioliasis?
Fasciola from raw liver and lingulatula serrata from undercooked viscera of goat and sheep

No.
What’s the diagnostic stage of p. Westermani?
Egg in sputum or stool.
What’s the infective stage of p. westermani?
Encysted metacercaria in undercooked crustaceans like shrimp, crab or cray fish.
What are the two intermediate hosts of p. westermani?
1st is Semisulcospira snail
2nd is crustaceans
What’s the habitat of p. westermani in humans?
The lung.
What’s the clinical picture of lung flukes?
Chronic productive cough (brownish), chest pain and pleural effusion.
What’s the radiological findings in a patient with p. westermani?
Nodular ring shadows and cavities
What’s the treatment of lung flukes?
Praziquantel and Bithionol
What is cysticercosis?
Infection with the larval stage of T. Solium
Man acts as a definitive host for cysticercosis? True or False?
False. Man acts as a blind intermediate host.
What are the routes of infection of cysticercosis?
Ingestion of raw contaminated vegetables (heteroinfection), or auto infection which can be external (hand to mouth) or internal due to regurgitation of food into the stomach causing the egg to hatch in the acidity of the stomach.
What is the clinical picture of cysticercosis based on the site?
Skin: subcutaneous painless nodules
Muscle: pain and weakness
Eye: loss of vision
Brain: neurocysticercosis
What’s the drug of choice in cysticercosis? And what are the alternative drug?
Albendazole is the drug of choice.
Praziquantel is the alternative. Also surgical removal whenever possible.
Man acts as a blind intermediate host in two parasitic diseases. Mention.
Cysticercosis and Coenurosis
What’s the definitive host of coenurosis?
Dogs.
What is the organism that causes coenurosis?
Multiceps multiceps causes coenurosis cerebralis while multiceps serrialis causes coenurosis serrialis.
What’s the intermediate host fo multiceps serrialis?
Rabbits and man.
What’s the intermediate host for coenurosis cerebralis?
Sheep, cattle and man.
What’s the infective stage and mode of transmission of coenurosis?
