Babesia spp.
Babesia is a ______________ parasite requiring mammals as primary hosts, and ticks as intermediate host or vectors.
A. monoxenous
B. heteroxenous
B. heteroxenous
Known biiological hosts of Babesia
Hard ticks (family Ixodidae)
Three developmental phases of the Babesia life cycle.
- merogony in the RBC
- stages of gamogony in the gut and epithelium
- sporogony accompanied with multiple fission in various cells and organs forming sporokinetes, and the development of infective sporozoites
Blood parasites that exhibit malarial-like infections
Babesia
Babesia is confused with the rings froms of this spp but lack malarial pigment.
P. falciparum
True or False.
Larger forms of Babesia (B. bigemina and B. caballi) are more pathogenic than smaller forms like Babesia bovis which are less virulent.
False. Smaller forms are more pathogenic; larger forms are less virulent.
Primary host of Babesia
Mammals (man only becomes an incidental host)
Rodents
Infective stage of Babesia
Sporozoites
