Infective stage of C. parvum?
Oocysts & Sporozoites
This morphological form of C. parvum is spherical, oval and is approx. 5 micro met. DOES NOT STAIN WITH IODINE and is ACID FAST
OOCYST
This morphological form of C. parvum is:
Double walled
Only stage that can live ex vivo
Embeds itself in gut epithelium
OOCYST
This morphological form of C. parvum is:
Crescent or bow-shaped
Anterior is SLIGHTLY POINTED and the
posterior is END-ROUNDED
Sporozoites
In Sporozoites of C. parvum where is the nucleus located?
Posterior third of the body
This morphological form of C. parvum is:
This morphological form of C. parvum is:
This morphological form of C. parvum is:
Round or oval intracellular but is in an exocytoplasmic form
Has a 1 single nucleus
Trophozoites
This morphological form of C. parvum is the transitional stage from sporozoites and merozoites to meront
Trophozoites
Infective stage of C. parvum: Oocyst; Dosage?
132 Oocyst
Give 5 Clinical manifestation is a person has been infected with C. parvum?
Hint: abnormal gut symptoms
● Diarrhea
● Abdominal cramps
● Nausea
● Vomiting
● Low-grade fever
Disease term referred if one is infected with C. parvum?
CRYPTOSPORIDIOSIS
This method of diagnosis allows the oocyst to stain red; is acid fast stained stool smear, can be fluorescent based?
Microscopy
This method of diagnosis detects Cryptosporidium antigens in the stool sample? Another term for ELISA
Enzyme Immunoassay
These medications may alleviate
some of the diarrheal symptoms however the
latter is contraindicated for AIDS patients.
Paromomycin and Nitazoxanide
