Human 
filariasis 
Nematodes 
in mosquitoes 
IGG KEPORT OF TRAVELLING PATHOLOGIST AND PROTOZOOLOGIST 
filaria embryos found. This was in a man admitted to the Wau hospital. He had Filaria 
pemtans in the blood, and was also suffering from marked lymphatic leucluemia. A blood 
count showed 4,770,000 red cells, and 354,000 whites. The increase in the wliite cells was 
due solely to the presence of small lymphocytes. The spleen was enormously enlarged, 
extending across the middle line of the abdomen and into the right iliac fossa. This patient 
was not a native of the Sudan, hut had come from the south. 
Finally, it may be mentioned that in the dissection of mosquitoes encysted nematodes, 
probably filaria embryos, were found on one occasion in the thoracic muscles of Taniorhynckus 
teiiax. This was at Nasser, on the Sohat, and I thought that possibly this was a stage in the 
development of the filaria of the toads which were infected at this place. This mosquito 
and others fed on infected toads gave only negative results. The embryos all appeared to die 
in the stomachs of the mosquitoes. The presence of the filaria embryos in Tteiiiorhynchus 
tejiax is interesting in the light of Low’s discovery of similar nematodes in another species 
of TiBniorhynchus— Tceniorhynchus fuscopenJiaUis. 
The collection of parasitic worms I have handed over to Dr. Leiper, Helminthologist to 
the London School of Tropical Medicine, who has kindly consented to examine the material. 
An account by him will be found at another part of this volume {page 187).
