 Pathogenicity of Spirochaeta crocidurae.] — Bull. Sac. Path. Exot., 

 Paris, X, no. "8, 10th October 1917, pp. 694-696. 



In a recent paper the presence of Spirochaeta crocidurae was recorded 

 in the blood of a shrew, Crocidura stampflii [see this Review, Ser. B, 

 V, p. 98]. The present paper describes experiments in which these 

 parasites, taken from the blood of the shrew, have been successfully 

 transmitted to other animals, including the common mouse, Mus 

 musculus, the field-mouse, Arvicola amphihius, the white rat and 

 several species of Avild rats {Mus rattus, Mus alemndrinus, Mus 

 decmnanus, etc.). The monkeys, Cynocephalus and Cercopithecus, are 

 susceptible to the virus, but they have not been fatally infected. 

 Rabbits and guinea-pigs on the other hand have always proved 

 resistant to infection.

In these experiments a flying-fox {Cyn.onycteris straminea) was tested 

 with respect to its susceptibility to various forms of malaria. The 

 results showed that this bat is apparently not susceptible to sub- 

 cutaneous injections either of Plasmodium falciparum or of P. malariae, 

 and appears to be equally resistant to the bites of Anoptheles

 pp. 731-732. 



The susceptibility of the flying-fox to infection by Trypanosoma 

 gambiense has already been recorded [see this Revieiv, Ser. B, iv, p. 101]. 

 The abundance of these animals throughout the Congo and the facility 

 with which they can be kept in cages, renders them very valuable 

 for laboratory work in diagnosing human trypanosomiasis in regions 

 where guinea-pigs and monlceys are difficult to procure. They are 

 numerous in the forest belts along the river banks, where Glossina 

 abound, and must therefore be reckoned with as reservoirs of the 

 virus.

A French soldier in hospital at Paris was suspected of malarial 

 infection and upon examination was found to harbour numerous 

 schizonts of Plasmodium vivax. This man, who is not known to have 

 had any previous attack of malaria, has served throughout the AYar
