B. COLI INFECTION 223 
belong to the colon group. [The author has studied the bacillus of 
the grouse disease a culture of which was obtained from Krahl and 
found it to be B. coli communis.] Migula designates it B. scotius. 
Cobbold also describes a disease of grouse. Leslie* who mentions 
a large number of diseases, many of which are parasitic, concludes 
that Klein and Cobbold worked with two distinct diseases, Klein 
with an acute infectious pneumonia and Cobbold with emaciated 
birds that had probably died as a result of extreme parasitism. 
Quail disease (Colibacillosis tetraonidarum). In May, 1907, Morse 
(cireular No. 109, Bureau of Animal Industry) described a disease of 
quail characterized by congestion of the lungs, focal necrosis of the 
liver, and intestinal ulceration. He found the cause to be a member 
of the colon group of bacteria. This seems to have several centers 
of infection in this country. Several species of quail and grouse are 
susceptible. While there are strong resemblances between this affec- 
tion and the grouse disease described by Klein, Morse assumes that 
they are not identical. 
Enzootic in cattle caused by a bacillus of the enteritidis group. In 
1902, Mohler and Buckley described an outbreak caused by B. enteri- 
tidis among cattle in a stable of 21 animals of which eight contracted 
the disease and died. Three others exhibited the early symptoms. 
The symptoms were first refusal of food, suspension of urination 
and diminution in lactation. There was excessive salivation in some 
cases. The temperature varied from 102.7° to 104.1° F. The visible 
mucose were congested. There was a wild expression in the eyes and 
the animals were very excitable. The gait was irregular. Convul- 
sions set in prior to death. 
The duration of the disease varied from two days to several weeks. 
Morbid anatomy. In the acute cases the anatomical changes 
were very slight. The most noticeable and characteristic lesion 
observed consisted of petechial hemorrhages under the endo- 
cardium. These were present in every case. There were occasional 
blood extravasations in the intestinal mucosa. There was marked 
injection of the blood vessels of the meninges and blood tinted fluid 
in the cavity. The chronic cases presented a wider range of lesions 
in the organs. 
Cultures of the bacillus were obtained from the different organs. 
The bacilli were found in small numbers in cover-glass preparations
