infective form spirals
encysted larvae in striated muscles
type of life cycle
direct but for the cycle to continue it sneed to be transmitted to another host of the same species or a different species and so optimum host= pig
life span of tichenalla spirals
very short, male dies as soon as finished mating and female areoun 4 weeks- 4 months
what does the female give birth to in trichenlla
LARVAE - so viviparous
rules for pork meat
smoking, drying or salting does not destroy the larvae . prolonged freeing decontaminates the meat
what’s the disease of spirals called
trichinosis
diagnosis of spirals
direct and indict methods muscle biopsy see the larvae - deltoid or biceps od gastrocnemius are usually selected
xeondiagnosis; feeding rats
indirect: hisorty of eating raw or undercooked pork about 2 weeks earlier along with an epidote of gastroenteritis
bloods- esopniphillia, massive hyper gamma, and iG E

intradermal test for trichella
Bachman test uses the larval antigen and you get an erythematous wheal 15-20 mons. the test remains positive years after infection
trichenella lives

mild cases : supportive consisting of bed rest analgesics and antipyretics
moderate: albdendazole /mebendazole
severe : add cs to the adlbendaxole
prophylaxis of trichenlla
Curing (salting), drying, smoking, or microwaving meat alone does not consistently kill infective worms;
freeze food
cook food properly
stop pigs from eating garbage
