Summary Controlled feeding experiments conducted with adult specimens of Blattella germanica mounted on wax blocks are described. Roaches fed an exclusive diet of molar sucrose lived for periods up to 205 days with an average longevity of about 50 da

Mutational loss of pesticin I, a bacteriocin-like substance produced by Pasteurella pestis , is known to result in concomitant loss of a coagulase and fibrinolytic factor. No relationship was detected between pesticinogeny and other tested properties

Pasteurella pestis within nelutrophiles and macrophages removed from the peritoneal cavity of guinea pigs dutring experimental plague were shown to be viable by direct microscopic observation of the infected phagocytes incubating in sutitable bacteri

One of the characteristics of virulent strains of Pasteurella pestis is their capacity to become resistant to phagocytosis.1,2 This resistance appears to depend on the presence of certain specific antigens in the microorganism.3,4 We reported recentl
The hypothesis that the ability of Pasteurella pestis to resist phagocytosis is the major determinant of its virulence has been re-evaluated in the light of recent evidence. Lethality titrations of virulent phagocytosis-susceptible plague bacilli wer

This report presents evidence that when avirulent strains of P. pestis that produce the capsular antigen Fraction I are grown under conditions that induce a high degree of phagocytosis resistance in typical virulent strains, they also acquire the sam
