This is really a fairly interesting question whose answer may lie in 
the history of science (although admittedly I've not scoured the 
leishmanial literature in a serious fashion for several years).  By 
that I mean scientists' uses of infected animals may have precluded 
investigation of vertical transmission, at least in a serious way.  
Certainly hamsters can exhibit very heavy infections with amastigotes 
in the gall bladder and a variety of other typically unreported 
places, and so transplacental infection seems likely.  Cotton rats 
might be a good host to try some vertical transmission studies with; 
they seem to carry a very heavy infection without all of the pathology
one sees in hamsters.  Years ago we had good luck breeding cotton 
rats by putting male and female together in a cage with a coffee can 
with cotton in it, and leaving the can and cotton in after removing 
the male (usually after three or four days).  That way the female had 
a place to hide and could build a nest.
