What is the vector of Leishmania ?
Sandflies (Phlebotomous spp. and Lutzomiya spp.)
Location of Giardia intestinalis
small intestine, extracellularly (in the host) (trophozoites)
- Giardia form of transmission
- fecal-oral: cysts
- contaminated food
- contaminated water
Number of flagella of Giardia
8 (1 pair anterior, 2 pairs posterior, 1 pair caudal)
Which floatation solution is used for Giardia
zinc sulphate -FAUST
How does Giardia reproduce?
binary fission (asexual)
Order of Giardia?
Diplomonadida
Form of transmission of Trichomonas Foetus
Coitus, AI, gynaecological exam
Host of Trichomonas Foetus
Bovine
Principle host of Trichomonas gallinae
Main- pigeon, chicken, turkey and wild boars
What is the form of reproduction in family Trichomonadidae?
longitudinal binary fission
Intravital diagnosis of Trichomonas in pigeons?
Lesions in upper GIT- mouth (beak cavity), pharynx, esophagus, crop, proventriculus, liver.
We find protozoans in lesions
How is Histomonas transmitted?
In the eggs of the caecal worm- Heterakis Gallinarum
Which group of protozoa possesses an axostyle?
Order-Trichomonadida
Genus- Trichomonas
Order- Diplomonadida
Genus- Giardia
For diagnosis of Sarcystystosis of pigs we investigate
tissue samples

5. Conoid
Organelles that do not belong to the Apical Complex:
1. Mitochondria
2. Nucleus
3. Golgi Apparatus
4. ER
5. Cytoplasm
A facultative parasite is an organism:
an organism that exhibits both parasitic and non-parasitic modes of living DOES NOT ABSOLUTELY DEPEND ON THE PARASITIC WAY OF LIFE, but is capable of adapting to it if placed on a host
Vertebrate host of Leucocytozoon is:
chicken
Oocysts of Cryptosporidium are smaller than …
Smaller than 10 um (4-6 um)
