ABSTRACT
The quantitative buffy coat [QBC] capillary tube was compared with both the thin and thick films in the diagnosis of malaria among 3 groups of hospitalized patients. Group 1 comprised subjects with no symptoms or signs, group 2 comprised patients with fever and rigors of unknown cause, and group 3 comprised treated malaria patients consulting the hospital for a follow up. The QBC test showed more sensitivity than the 2 conventional methods in the 3 groups as follows: In group 1 the QBC was positive in 14.2% compared with 9% only in either thin or thick blood films. In group 2 the positivity was 95.1% compared with 79.3% and 76.8% in the thin and thick blood films, respectively. In group 3 the sensitivity was 22.9% compared with only 5.7% in both the thin and thick blood films. It was found that the QBC technique in addition to its high sensitivity is very practical, reliable, simple and easy to perform. No doubt, the thin blood film is still the method of choice in species identification of malaria parasites

Stool and urine from 320 subjects in Ain shams region, and 200 subjects in Nasr city were collected and examined for parasites. All these subjects were suffering from abdominal troubles. The results revealed a marked relation between parasitic Infection and abdominal troubles, especially in Ain shams region [80%], and to a lesser extent in Nasr City [51%]. The commonest parasite in Ain shams was Giardia lamblia [20.3%], and in Nasr city was E. histolytica [13%]
ABSTRACT
The circumoval precipitin test was performed on 60 male patients with active bilharziasis and 20 control normal subjects. Both types of S. mansoni and S. haematobium eggs were used as an antigen. The percentages of positivity, egg reactivity, and the refraction's precipitation intensity were lower on using S. haematobium eggs than with S. mansoni
