This paper deals with the quantitative variations, under different environmental conditions, of the bristle numbers of the mutant scute-1 in Drosophila melanogaster. The genetic factor “scute” was discovered by BRIDGES in 1916 (unpublished). Since 1929, when other alleles of scute were found at the same locus, the original scute has been designated as scute-1. Figure 1 shows the position and no...

To determine whether particular Borrelia burgdorferi s.l. genospecies associate solely with rodent reservoir hosts, we compared the genospecies prevalence in questing nymphal Ixodes ticks with that in xenodiagnostic ticks that had fed as larvae on rodents captured in the same site. No genospecies was more prevalent in rodent-fed ticks than in questing ticks. The three main spirochete genospecie...
