OTHER GERM DISEASES AMONG ANIMALS 311 
Lumpy Jaw, Malignant Tumor, Wooden Tongue, Actino- 
mycosis.—These three names are applied to the same disease, 
located, however, in different places The cause of the trouble 
is one of the higher types of fungi rather than a bacterium. The 
name of the organism is Actinomyces bovis and it differs from 
bacteria in forming longer threads and in branching (see page 
13) When it finds entrance into cattle, generally through the 
mouth, it may invade the tissues and produce the diseases named 
above Sometimes it is found in the throat, lungs, and skin 
It is most common in cattle, but it also occurs in swine, and 
may be given to other animals by inoculation. It occasionally 
occurs in man ‘The disease is not common, though it causes 
considerable loss at times, since it is serious and apt to be fatal. 
It produces hard tumors that invade the bones or other tissues, 
causing great distortion. The disease is not contagious and 
its source Is as yet unknown 
General Inflammatory Troubles.—Inflammatory, suppura- 
tive, and tumor-forming troubles are liable to occur in almost any 
part of the body of man or animal These are commonly caused 
by bacteria, particularly by the class called Streptococct. The 
affections do not form any specific disease, but receive a variety 
of names according to the location of the trouble. For example, 
when the streptococcus produces inflammation of the udder it 
is called garget, mammiiss, or mastitis, while hoof rot and navel ill 
represent other types of inflammation located elsewhere. The 
streptococci that cause garget have been found abundantly in the 
milk of cows and are believed to be the reason for some of the 
illnesses in mankind that follow the drinking of raw milk. Various 
forms of sores, bowls, abscesses, and the inflammations following 
wounds are also caused, largely or wholly by streptococci, and 
most types of inflamed tissue in an animal may be rightly attrib- 
uted to the action of this class of bacteria. 
Another bacillus associated with a variety of troubles among 
animals is named B. necrophorus. This organism produces more
