25
apicomplexa conoidasida what type of parasites
parasites of cells (usually intracellular) -> obligate parasites
26
gregarinasina taxonomy
``` kingdom- protistis class- sar- eukaryotes order- alveolata family- apicomplexa group- conoidasida ```
27
gregarinasina host
invertebrates
28
gregarinasina relationship to host cell
primitive so large they don't enter cell -> inside cell membrane but not in cytoplasm so cell doesn't know they're there when they die - myzocytosis - attach to cells via feeding organelle
29
gregarinasina life cycle
- have sex (haploid until they fuse, sex in host, cyst in environment)
30
gregarinasina organ effected
intestinal tract
31

32
cryptosporidium homminis host
humans
33
cryptosporidium homminis life cycle
Oocyst ingested -> Sporozoite in body -> Trophozoite when penetrate cell -> Asexual repro to make merozoite -> Sex to form type II meront -> Undiff gamont becomes macro & micro -> Zygote
34

cysts from water in environment and food
35
cryptosporidium homminis organ effected
intestines
36
cryptosporidium homminis grows where
only in animals
37
cryptosporidium homminis see infections when
most infections in summer b/c thats when everyone is swimming

39
cryptosporidium parvum host

40
cryptosporidium parvum lifecycle
Thin wall oocyst stays in host causing auto-infection & thick wall oocyst exits (pop out of cyst & penetrate intestinal mucosa) - Oocyst -> Sporocyst -> Sporozoite ->Merozoite (trophozoite) -> Schizont (meront) -> Schizozoite (go b/w last 2, 3 times over and over) ->Gamonts (macro & micro) -> Fert of macro by micro -> Zygote
41
cryptosporidium parvum transmission
cysts from environment
42
cryptosporidium parvum organ infected
intestines
43
cryptosporidium parvum grows where
only grows in animals
44
cryptosporidium parvum infections occur when
summer bc thats when everyone goes swimming
45
cryptosporidium closely related to who
- gregarines | - this = why almost all anticoccidials and antimalarials = inadequate in controlling this parasite
46
cryptosporidium is what kind of dx
REPORTABLE
47
apicomplexan life stages
oocyte -> sporocyst (if present) -> sporozoites -> may more may not become a cystozoite -> merozoite (toxoplasma tachyzoites and bradyzoites) -> schizont -> schizozoites -> macrogamont and microgamont -> fertalization of macrogamete by microgamete -> zygote
48

rigid sequence of asesual and sexual phases of multiplication and development
51
coccidiasina transmission

52
coccidiasina what kind of parasite
obligate intracell parasites that destroy host cells
