Treatment would be by dusting with quicklime, or by lotion 

 containing turpentine, oil of tar, creolin, lysol, cupric sulphate, 

 ferric sulphate, butter of antimony, etc.

SACCHAROMYCES GUTTULATUS IN THE RABBIT. 



Saccharomyces Guttulatus is found in the intestinal mucus 

 of cattle, sheep, swine and rabbits, without proving appreciably 

 pathogenic. In the gall ducts of the rabbit however it has been 

 found by Nasse and Remak to form masses like tubercles which 

 interfere with the functions of the liver. 



The cryptogam appears in the form of ovoid, dark, brown cells, 

 each having from two to four clear transparent droplets from 

 which the name has been derived. They are arranged in pairs 

 or short chains or in clumps. They do not appear to form any 

 irritating nor poisonous product and produce mechanical trouble 

 only. 



ASPERGILLOSIS OF THE AIR PASSAGES IN BIRDS 

 AND MAMMALS. PNEUMOMYCOSES. 



History: Cause: Aspergillus, mother cells, branching transparent fila- 

 ments, downy layer, vertical filaments, tufts or heads, spores or conidia. 

 Grows on dead organic matter, but also on living surfaces. Varieties : As- 

 pergillus — -smoky, black, sea-green, translucent. Accessory Causes : Youth, 

 delicacy, close buildings, cramming, darkness, damp. Symptoms : Birds : 

 Wheezy, croupy expiration, catarrh, dyspnoea, moping, somnolence, debil- 

 ity, sunken head, wing, tail, eyelids, ruffled feathers, inappetence, thirst, 

 hyperthermia, diarrhcea, emaciation, death in one to eight weeks. Lesions : 

 On Eerial mucosa back of nose tubercle-like masses or greenish patches, 

 showing a mycelial surface ; pseudo-tubercle in liver, diaphragm, peritone- 

 um, intestine ; contains many leucocytes and spores. Pathology : Inhaled 

 spore grows on mucosa causing congestion, positive chemiotaxis, lymphoid 

 and giant cells, fibroid organization. Intravenously, pseudo-tubercle in 

 liver and lungs ; intratracheally, death in 10 to 20 days. No strong toxin.
