CuRASsoN (M. G,). Sur le Traitement des Trypanosomiases animales 

 au Soudan.— ^mZ?. Soc. Cent. Med. Vet., no. 9, 1918. (Abstract 

 in Trop. Vet. Bull, London, vn, no. 1, 30th March 1919, pp. 8-10.) 



In this discussion on the treatment of the various animal trypano- 

 somiases in the French Sudan it is stated that " baleri," due to 

 Trypanosoma pecaudi, occurs more frequently in the ox and zebu 

 and crosses between tliem than has hitherto been recorded. The 

 author encountered the condition only among these animals in the 

 north-western regions of the French Sudan, but it exists in an 

 enzootic form in other districts. Tsetse-flies {Glossina), which 

 are generally considered to be the transmitting agents, do not occur 

 in this region. On the other hand Stofnoxys is common in the swampy 

 areas. " M'bori," which is clinically identical with surra due to 

 T. evansi, is a very common disease in camels in the northern part 

 of the French Sudan, especially around swampy districts where 

 Stomoxys are the only biting flies seen.

The antimalarial measures here described aimed at destroying the 

 breeding-places of mosquitos. On the whole, success was not attained 

 as regards immediate results, but the work should be persevered 

 in and extended over a larger area. Contrary to a widespread opinion 

 the operations must not cease in winter. At Fiumieino larvae of 

 Anopheles maculipemiis (daviger) were found in collections of water 

 swollen by the November rains, and at the end of December those 

 of A. bifurcatus also occurred. It is pointed out that when 

 the measures were begun early in April 1918 the descendants of 

 mosquitos that had hibernated were met with.

 Infectious Diseases taken at the English Camp at Cimino.] — Ann.

This is the fifth of a series of six reports on the sanitation of coastal 

 zones in 1918 ; the first four deal with anti-malarial work in Italy 

 and the sixth relates to the same subject at Vallona. 



The anti-malarial work at Cimino was done on the recognised lines 

 of drainage, screening and quinine prophylaxis. In the entomological 

 laboratory research of a purely scientific nature was also carried 

 out with a view to solving such questions as whether eggs laid 

 by mosquitos harbouring haematozoa also contain malaria organisms. 

 It has been experimentally found that a 1 : 10,000 solution of copper 

 sulphate indirectly checks the development of mosquito larvae by 

 killing the minute algae that they feed on. The mosquitos hitherto 

 found are Anopheles maculipennis, A. bifurcatus, Culex pipiens, 

 G. hortensis, Culex sp., Tfieobaldia annvlata, T. longiareolata {spathi- 

 palpis), Theobaldia sp. and Ochlerotatus dorsalis. The methods 

 adopted against flies and lice are also briefly outlined.
