can result in autoinfection

due to autoinfection

to detect Abs

treat even if its asymptomatic

5 to 7 days

causative agent for swollen belly syndrome

TRICHINA WORM or muscle worm

pigs and other mammals that are carnivores or omnivore in nature, so why men infected if the final host are pigs, it is because we man are considered as accidental host or the dead end host

encysted larvae (we use muscle biopsy instead of stool)

encysted larvae

clinical features depends on the stage

5-7 days, pain in abdomen, nausea, vomiting, diarrhea

fever, urticarial rash, splinter hemorrhages, periorbital & facial edema

asymptomatic in light infections; if heavy na sa myalgia na, weakness in heavy infections

encysted larva

eosinophilia between 2nd & 4th week

to detect specific Abs by

adult worms
