Micro Bio- Parasites And General Systems Infected

Front 1

trophozoites cause ulcerative FLASK shaped lesions in lg intestinge. can cause granulomas in brain, spleen, liver, lungs and skin

sx. BLOODY diarrhea, leukocytosis, anemia, nausea, vomiting, abdominal pain

Back 1

amebiasis

tx with metronidazole

Front 2

what can occur with amebiasis in

Resp?
Hep?
Brain?
EYE?

Back 2

Resp=infections w/ pain and cough

Hep=chills, fever,

Brain abscess- can kill


Donjunctivities w/ FETID ODOR

Front 3

commensal bacterial co-infection on the eyelids and ocnjuncitva play a role. collaenase and proteolytic enzymes released by trphozoites

*PARTIAL or COMPLETE RING develops in eye

*antibody dependent cellular destruction is promoted

SX:
*uveitis, optic neuritis, corneal keratitis

Back 3

Acanthoamoebic keratitis

Front 4

what bacteria does acanth keratitis love?


what are cephalic problems?
what are skin problems?

Back 4

loves pseudomonas

forms granulomatous amebic encephalitis in immunocompromised

skin lesions occure months before invasion of brain and are ulcers, nodules, abscesses and amebic granulomas

Front 5

intestinal villi are infected and atrophy and fuse w/ infiltate

sx:
watery diarrhea, weight loss, abdominal pain, nausea,

keratitis(from microsporidia0
or pneumonitis if gets into lung

Back 5

microsporidiosis

Front 6

cercaria migrate under the skin of humans producing mechanical toxic damge but DO NOT ENTER blood vessels to become adults

sx:
-serpinginous tunnel lesions, vesicles, papules, rash with itching and secondary bacterial infection

shoudl go away in 4-5 days but can persist if hypersensitive

Back 6

Schistosome dermatitis,

swimmers itch

Front 7

adult worms lie attached by SPiens on rostellum of small intesting where metabolic by products interact with mucosal surface

sx:
-inflamation, rash, vomiting, diarrhea, nervouse syspmtos and allergic response

Back 7

Dipylidiasis

Front 8

intestinal obstruction causes inflammation and irritation at site of attachment of scolex. can also exist in larvae stage and displace tissue and provoke cellular inflammatory rxn

sx:
-abdominal pain and weight loss w/ weakness, dizziness, ha, vomit, diarhea and allergic response

Back 8

adult worm taenisis

Front 9

how does larvae of teaniasis present (cysticercus cellulosae)

Back 9

HA, nervous, manifestations, subrentinal masses, keratitis, insomnia, seizure

Front 10

larvae cause skin lesions and allergic rxns develop. can cause inflammation of alveoli w/ hemorrhaging if trapped in lungs. adult worms suck blood from small intesting producing inflammation, eosinophilia, blood, loss and Fe defic anemia

sx:
-infection produces skin rashes, Fe defic anemia, anorexia, weight loss, blurred vision, abdominal pain, nausea, vomit, diarrhea, malnutrition, wheeze and pneumonitis

Back 10

Ancylostomiasis

Front 11

which is an adult worm that results in intestinal blockage, malnutrition, eosionphilia and when distrubed may lodge into bile duct or appendix


sx. abdominal cramps, diarrhea, loss of appetitiis, malnutriton appendicits?

Back 11

ascariasis

Front 12

what happens if ascariasis gets into lungs?

what causes neurologic sx?

Back 12

Loffler's syndrome in lungs (eosinophilia in lung tisse)

toxic an allergenic metabolites cause neurologic symtpoms(retinal granulomas)

Front 13

adult female worms irritate anal area when laying eggs. itnese scratchin and sometimes bacterial infection

Sx:
-appendicitis and pelvic periotenal graulomas
-anal itching, scratching, insomnia

Back 13

enterobiasis (human pin worm)

Front 14

larvae penetrate skin adn wander around under dermis but never enter blood. local eosinophilia around tunnesl and persists for months if untreated

sx. serpinfinous tunnel with icthin, red papulea and edema

Back 14

cutaneous larva migrans (creeping eruption)

Front 15

migrating larvae produce inflammation, heper eosinophilia, skin rash , fever,

damage depends on #of eggs ingested, migration route of larvae adn stregnth of immune response

sx: fever, LOSS OF VISION, cough, pneumonitis, edema,

Back 15

visceral larva migrans

Front 16

early has malasie abdominalpain, nausea, vomit, diarrhewa, fever, myalgia for 5 days

progress to cough, INTENSE MUSCLE PAIN, periorbital edeam and myocarditis to CHF 7-14 dyas

after 2 weeks, cachexia of infection , myositis with pain and SWELLING OF ARM AND LEG MUSCLES, rash , eye problems, pneumonitis

Back 16

Trichinosis

Front 17

what causes inflammation, toxic effects and hypersensitivity of trich?


what causes inflammatory response w/ eosinophilia?

Back 17

larvae and adult worms


larvae also produce inflam respons w/ eosin

Front 18

Lice suck blood injecting saliva causing pustular lesions at site of bite

prim hypersenstivity attained 3-8 months after original infestation

sx:
-papules, ulceations, intense itching and discoloration
may have toxic frollicular conjucntivitys from feces

Back 18

Lice infestaiton

Front 19

larvae bit through skin of humans injecting saliva that is antigenic and contains lytic compounds to dissolve tissue.

DO NOT SUCK BLOOD OR BBURROW INTO SKIN

allergic rxn develops following first expose
re

SX:
-deep red lesions with attendant loss of sleep for days/weeks
-small itching red s pots develop into dermatitis where clothing is tight

can get secondary bact. infecton from intense scratching

Back 19

Mites (trombidiosis)

Front 20

mites live in serpinginous cutaneous burrow in humand and progress w/o symptoms while crawling and laying eggs. pap, vesic or pusutalr lesions produced by allergic rxn to eggs, larvae, mites or feces

sx:
-reddish elevated tracts in skin b/w fingers, wrists, forearms and bend of knee and elbow

also inguinal area,penis and shoulder blades that develop into SINGLE LESIONS OR RASH LIKE LEIOSN OCCURIN IN TRACKS

INENSE ITCHING leads to scratch, which spreads.
