Parasitic Infection Flashcards
Caused by a nematode worm which embedded itself in the lymph node during the chronic stages causing mechanical obstruction in the involved lymphatic pathways leading to elephantiasis
Filariasis
Causative agent: Filariasis
Wuchereria bancrofti
Brugia malayi
Mode of Transmission: Filariasis
Bite of a mosquito harboring infective larvae
Signs and Symptoms: Filariasis
Primary stages (3 months - 2 years)
Fever, malaise, headache, chills, lymphangitis
Signs and Symptoms: Filariasis
Secondary
Embryo in circulation, asymptomatic
Signs and Symptoms: Filariasis
Tertiary terminal
With obstruction of lymphatic system
Elephantiasis
Management: Filariasis
Control the vector
Protect the individual and families in endemic areas
Hetrazan (Filariacide)
A blood fluke infection with adult male and female worms living in mesenteric and visceral veins of the host over a lifespan of many years
Schistosomiasis
The infected snails release cercariae, it survives in freshwater up to 48hrs during which time they must attach to human skin or to susceptible host mammal or die
Schistosomiasis
Causative agent: Schistosomiasis
Schistosoma mansoria (mansori)
Schistosoma haematobium
Schistosoma japonicum
Mode of Transmission: Schistosomiasis
From water containing free swimming larva which have developed in snails
Schistosomiasis
Signs and Symptoms: Schistosoma mansoria (mansori) and Schistosoma japonicum (liver and intestine)
Diarrhea, abdominal pain
hepatosplenomegaly
Melena
Schistosomiasis
Signs and Symptoms: Schistosoma haematobium (urinary tract)
Dysuria, hematuria at the end of urination
Management: Schistosomiasis
Health education (especially fishermen and farmers)
Proper disposal of feces and urine
Medical management (Praziquantel)
Medical management for Schistosomiasis
Praziquantel (biltricide)
