The blood picture was studied in 550 rural white children 5 to 14 years old in south-central Louisiana. Of these 197 were infected with trichuris; 140 with trichuris and some other intestinal worm, usually ascaris; and 213 were worm-free. The blood picture was essentially the same in all groups, i.e., 11.22 to 11.52 grams hemoglobin per 100 cc. blood; 4.5 to 5.0 million erythrocytes per cmm. blood; mean corpuscular hemoglobin of 23.0 to 23.7 micro micrograms; and a relative lymphocytosis of 46.4 to 47.2 per cent. These children are known to suffer from undernourishment and it is suggested that most of them both parasitized and worm-free, suffer from a nutritional anemia. There is no evidence that the blood picture is effected by the trichuris infestation.
