MYCOSIS OF AIR-PASSAGES. 97 



By inoculating healthy pigeons with the spores of 

 fumigatus, by injecting them into the axillary vein, 

 Dieulafoy and Widal have shown that tuberculosis 

 of the liver and lungs takes place, ending fatally in 

 a few days. The tubercles very much resemble 

 those of true tuberculosis due to the bacillus. When 

 this Mycosis appears, it is usually in an epizootic 

 form. 



Prevention and Treatment. 



Cleanliness of the fowl-houses is most essential, 

 everything, such as straw, litter, &c, that may be 

 about should be burnt, and the houses cleaned down 

 with boiling water and corrosive sublimate, a pint of 

 10 p. c. solution to every gallon of boiling water. 

 Treatment is usually futile ; good, however, is said 

 to be done by putting the birds in a closed chamber 

 with tar-vapour, formed by putting a large spoonful 

 of vegetable tar in a pint of water and then stirring 

 with a red-hot iron. Only two birds affected with 

 apparent Mycosis have come under my notice : burn- 

 ing sulphur in a similar way was tried, but the birds 

 eventually succumbed, the liver being invaded as well 

 as the trachea with mould. 



This malady does not seem to be much known in 

 England, but when cases do appear they are usually 

 fatal.
