0 an abnormal increase in the number of eosinophils (= a type of white blood cells) in the blood: --
Eosinophilia is usually due to infection by parasites such as roundworms.
As in all patients with larval toxocariasis, eosinophilia was also most frequent in the 3-5 years old group of children (table 2).
The absence of eosinophilia, however, does not rule out the presence of toxocariasis.
On the other hand, among 136 patients with positive toxocaral serology, 58 patients (42.6%) had eosinophilia.
The intensity of eosinophilia, measured by the chamber technique, is also of some diagnostic value.
Serological response, eosinophilia in peripheral blood, occurrence of white spots in the liver and worm recovery from the intestine.
Nine participants with eosinophilia had a history of hay fever and two had a history of asthma.
Information on a patient's eosinophil count is, therefore, available to clinicians at no cost ; thus, screening for eosinophilia is intuitively cost-effective.
The chronic eosinophilia may be due to the prolonged larval migration seen in these hosts.
