cocci of one type was found to be accompanied by the production of slight 

 bactericidal activity for other tyivs. 



Studies upon the bacterial flora of samples of milk with higli cellular 

 counts as drawn from the apparently normal udder, L. H. Cooledge (ilichi- 

 gan Sta. Tech. Bui. 41 (1918), pp. 903-010, fig. J).— Work taken up in connec- 

 tion with investigations of the effect of diseases in the cow upon the milk deals 

 with the relation of high cellular counts to Bacterium abortus infected, strep- 

 tococci infected, and tuberculous udders, and to other abnormal conditions of 

 the cow's udder, respectively. The first of the four parts of the work is here 

 reported upon. 



"Milk from actively B. abortus infected udders is found to have an average 

 cellular count over five times as high as the apparently normal average. Udders 

 artifically infected with a broth culture of B. abortus were quick to show an 

 increase in the cellular count. B. abortus infection accounts for many of the 

 samples of milk which have high cellular counts as drawn from the apparently 

 normal udder. Many cases of high cellular counts can not be traced to B. 

 abortus infection. Milk with high cellular counts caused by B. abortus infec- 

 tion can not be considered dangerous for human consumption as this organism 

 has not been found pathogenic for man." 



A list of nine references to the literature is appended.

A chronic pox-like infection in goats and its successful treatment, R. V. 

 Stone and C. W. Fisher {Jour. Amer. Yet. Med. Assoc, 55 {1919), No. 5, pp. 

 536-543). — "A condition in goats, benign in character but of economic im- 

 portance through loss in milk production and flesh, has been observed. Lesions 

 in early stages resemble goat-pox. Whether true goat-pox or a condition having 

 lesions simulating those observable in goat-pox has not been determined. How- 

 ever, a pure Gram positive staphylococcus having an orange pigment and pro- 

 ducing marked hemolysis on uncooked blood agar has been isolated from every 

 specimen taken. 



"Bacterins prepared from this organism produce a rapid recovery in ca.ses 

 affected. This therapeutic value may be specific or nonspecific, but the organism 

 has been demonstrated as being particularly virulent for goats but nonvirulent 

 for guinea pigs and rabbits. Three distinct forms of infection have been suc- 

 cessively treated with bacterins. These forms are (a) arthritis, (b) exan- 

 themata, [and] (c) subcutaneous multiple abscesses. Cases in which bacterin 

 therapy is not employed do not recover rapidly but may persist at least a year 

 and a half." 



Observations concerning the dissemination of hog cholera by insects, M. 

 Dorset, C. N. McBryde, W. B. Nile, and I. H. Rietz {Amer. Jour. Vet. Med., IJf

 of Animal Industry of the IT. S. Department of xVgriculture presented at the 

 annual meeting of the U. S. Live Stock Sanitary Association, held in Chicago in 

 December, 1918. The studies were conducted with the house fly and lesser 

 hous(! fly, representing the nonbloodsucking species; and the stable fly, repre- 

 senting the bloodsucking species.
