Uruguay is situated in the temperate zone 
of South America contiguous to Brazilian territory 
which has a large amount of land in the torrid zone. 
The northern part of Uruguay carries on an active 
interchange of commerce in livestock with the 
W.-' 
breeders of Brazil and this latter country is completely 
infested with Boophilus Microplus which transmit the 
4 - 
l J 
ick fever (Piroplasmosis Bovina), known in these 
regions as "Triteza". Due to these circumstances and others 
the northern part of Uruguay which boi-ders on Brazil 
is also infested with the ticks (Boophilus Microplus). 
This state of affairs retards in a large measure cross¬ 
breeding, as all the bulls for breeding purposes brought 
into this territory die of tick fever (Piroplasmosis Bovina)
