Insect concerned: Pyrameis cardui. 



Paillot (1913) isolated two different "coccohacilli" 

 from the tissues and "blood of caterpillars of Pyrameis 

 cardui . He named these, Bacillus pyrameis I and Bacillus 

 pyrameis II .

BAC I LLUS R ICKETTS I FORM I S Noguchi 



Tick concerned: The wood tick, Dermacentor andersoni . 



Bacillus rickettsiformis was isolated "by Noguchi (1926) 

 from the wood tick. This "bacillus and two other micro- 

 organisms which Noguchi isolated from the same source, 

 morphologically resembled the rickettsia which causes spot- 

 ted fever. Bacillus rickettsiformis was more frequently 

 isolated than the other two. They were found to "be non- 

 pathogenic for laboratory animals and immunologically not 

 related to the spotted fever rickettsia. 



Bacillus rickettsiformis is moderately motile, and 

 lanceolate, fusiform, or orod -shaped. In old cultures 

 there is considerable pleomorphism. Since the organism is 

 a Gram negative, apparently non- spore -forming rod, the 

 generic name Bac illus is not correct according to accepted 

 nomenclature .
