1939; Janssen and Wedberg, 1952) : Organism isolated from the legs, 
antennae, and feces. 
Experimental vectors —Blatta orientalis, Italy (Cao, 1898) : Failed 
to recover the organism. U.S.A. (Tauber and Griffiths, 1942): Or- 
ganism toxic to the cockroach when injected. 
Micrococcus pyogenes var. aureus (Rosenbach) Zopf 
Synonymy.—Staphylococcus aureus. 
Disease.—Pathogenic. The cause of boils, abscesses, suppuration 
in wounds. Habitat: Skin and mucous membranes. 
Natural vectors.—Blaberus craniifer, U.S.A., Connecticut (Wed- 
berg et al., 1949): Organism isolated from feces, 
Blatta orientalis, Italy (Cao, 1906): Organism isolated from in- 
testinal contents. Cao in an earlier work (1898) failed to recover this 
organism from the cockroach. 
Blattella germanica, U.S.A. (Herms, 1939) : Organism isolated 
from the antennae. 
Cockroaches, U.S.A. (Longfellow, 1913) : Organism isolated from 
the legs, 
Micrococcus spp. 
Disease.—These organisms were obtained from pus or were desig- 
nated as staphylococci (i.e., pathogenic micrococci [Blair in Dubos, 
1948] ). 
Natural vectors——Blatta orientalis, Italy (Spinelli and Reitano, 
1932). Germany (Jettmar, 1935) : Organisms isolated from intestinal 
tract. 
Blattella germanica, Germany (Jettmar, 1935): Hemolytic staphy- 
lococci were isolated from the outer surfaces of IQ insects captured 
in a hospital operating room, 
Experimental vectors.—Blattella germanica, on shipboard (Morrell, 
1911): Two specimens were fed staphylococcic pus. The organisms 
were recovered in the feces, and cultures on agar were obtained from 
these. Germany (Vollbrechtshausen, 1953): Cultures of staphylo- 
cocci (obtained from the clothing louse) were injected, orally and 
anally, into cockroaches. Colonization and propagation in the intes- 
tines of the cockroaches lasted up to 6 to 8 weeks after heavy injec- 
tions. The organism was recovered from the feces of one insect 180 
days after the injection. 
Family NEISSERIACEAE 
Neisseria meningitidis (Albrecht and Ghon) Holland 
Common name.—Meningococcus. 
Disease.—Cerebrospinal fever.
