A NEW PASTEURELLOSE: WHITE SCOUR AND LUNG 
DISEASE OF CALVES IN IRELAND. 
By Prof. E. Nocard * 
Since several years, breeders of the southwest of Ireland suf¬ 
fer much ; they lose more than half of their calves. They mostly 
die in a few days, during the first week from their birth, after 
having a white, foaming, incoercible diarrhoea (white scour): 
others, in smaller number, die later, when eight or ten weeks 
old, after exhibiting signs, not well marked, of lung diseases ; at 
the post-mortem, numerous and large caseous or suppurative 
lesions of the pulmonary structures are observed (lung disease) 
The epizootic prevails principally in the counties of Lim* 
erick, Cork, Clare and Tipperary. All the farms do not have it ; 
some have never lost a calf with white scour ; but where it breaks 
out, it makes enormous ravages. One farmer has lost more 
than ioo calves in three years ; another has saved only one out 
of 35 born in 1900 ; with a third 22 have died out of 29; in a 
fourth 60 out of 70. Generally speaking, it may be said that, 
where the disease prevails, the mortality goes far beyond 50 per 
cent, of the births. 
The Department of Agriculture for Ireland has done me the 
honor to give me the scientific study of this severe disease ; I 
have been three weeks at Limerick, and in this short time which 
I thought would not be sufficient to organize my work, I have 
been fortunate enough to be able to elucidate the etiology of the 
disease and to suggest a simple and practical prophylaxy, which 
I hope will prove efficacious. 
Allow me to present you the report that I have addressed to 
the Chief of the Department of Agriculture.
