Parasitology Exam 1
Humans, primates and pigs (disease in pigs very common) - answersWho does
Balantidium coli infect?
Worldwide (however most human infections occur in warmer climates) - answersWhere
is Balantidium coli present globally?
Majority of people are asymptomatic. If malnourished or immunosuppressed they are
more likely to show signs. Although asymptomatic they will still pass cysts. Luminal
infection causes diarrhea and weight loss. Dysentery (blood, mucous, assault on
mucosal surface). Possible secondary infection. - answersWhat are the clinical signs of
Balantidium coli?
Fecal sample. Microscopy looking for cysts and trophies. If cysts dominate it is called a
"formed stool", if trophs dominate it is called "diarrhetric". Do not need oil immersion. -
answersHow is Balantidium coli diagnosed?
Wash hands. Clean food and water. - answersHow is Balantidium coli prevented?
Tetracycline. - answersHow is Balantidium coli treated?
Treat the water not the fish. Food fish = treat water with Copper Sulfate pH. Pet fish =
treat water with Formalin. (Usually too late to treat fish when detected so just start over.
Disease will quickly kill the fish. Once postures form there is often secondary infections
which are fungal or bacterial) - answersWhat is the treatment for Ichthyophthirius
multifilius?
Fish worldwide. - answersWho does Ichthyophthirius multifilius infect?
White Spot Diease. ICK. Each white spot on the fish is one troph (postures). If on the
gills it interferes with gas exchange. Skin irritant = "flashing". Hyperplasia = increase in
the number of host cells in order to try to fight off infection. - answersWhat is the
disease associated with Ichthyophthirius multifilius?
Humans worldwide - answersWho does Entamoeba histolytic infect?
Amoebiasis. Amoebic Dysentery. - answersWhat is the disease associated with
Entamoeba histolytica called?
Must attach to host cell via lectin. (If you have a lot of good bacteria, E hits cannot
attach to the host) - answersWhat does Entamoeba histolytic need to infect/attach to a
host?
, Asymptomatic are cyst passes. Symptomatic have diarrhea, dehydration, ulcer,
dysentery, blood mucous diarrhetic. If liver is involved = pain, abscess forms (cavity with
necrotic fluid, liquified tissue) - answersWhat are the clinical signs of Entamoeba
histolytica?
Yellow. A secondary bacterial infection. The amoeba will be around edges. Death is a
possibility. - answersEntamoeba histolytica. Necrotic tissue is usually brown but if it is
what different color it signifies what?
Fecal look for cysts and trophs. Second species called Entamoeba disbar may be
present, identical but non-pathogenic. Kits by the CDC to distinguish the two. -
answersWhat is the diagnosis of Entamoeba histolytica?
Metronidazole - answersWhat is the treatment for Entamoeba histolytica?
Mammals and humans - answersWho does Entamoeba coli infect?
Worldwide - answersWhere does Entamoeba coli infect globally?
Lives in the large intestine and eats bacteria - answersWhere in the body does
Entamoeba coli infect? What does it do?
8 nuclei, they are off center and peripheral chromatin looks "clumpy" in troph form -
answersHow many nuclei are in the cyst form of Entamoeba coli?
Humans and other mammals. Smallest parasite in humans. - answersWho does
Endolimax nana infect?
Large intestine - answersWhere is Endolimax nana present in the body?
4 nuclei - answersHow many nuclei are present in the cyst form of Endolimax nana?
Humans and pigs - answersWho does Iodamoeba butschlii infect?
Large intestine - answersWhere is Iodamoeba butschlii located in the body?
Humans and dogs - answersWho does Entamoeba gingivalis infect?
Present in the mouth on the surface of teeth and gums. Eats bacteria. "Kissing
amoeba". No cyst formed. - answersWhere is Entamoeba gingivalis present in the
body?
Lakes, ponds and fresh water. Warm water. Very common. - answersWhere is
Naegleria fowleri commonly found?
