Giardia duodenalis assemblages in Egyptian children with diarrhea.

Giardia duodenalis is considered the most common cause of parasitic diarrhea worldwide. Genetic studies revealed that at least eight assemblages (A-H) exist. Of these assemblages, A and B are found primarily in human beings and occasionally in animals.

Value of the quantitative buffy coat capillary tube test (QBC) in the microscopic diagnosis of bancroftian filariasis.

The diagnostic performance of the commerical quantitative buffy coat capillary tube technique was compared with the standard diagnosis of filariasis by microscopical examination of Giemsa stained thick blood films. The comparison was conducted among 83 subjects. The QBC test was highly sensitive than the thick blood film in detection of microfilaraemic patients.

The efficacy of the volatile oils of three plants for controlling Lucilia sericata.

Myiasis is one of the most important parasitic diseases, which affects the human welfare. The volatile oils of three plants were tested against adult Lucilia sericata. The LC50 was 80 ppm by Anethum graveolens, 180 ppm by Conyza dioscoridis and 130 ppm by Mentha microphylla.

An experimental vaccine providing heterologous protection for Leishmania species in murine model.

Five groups each of 20 BALB/C mice were immunized by heat killed L. donovani promastigotes. Two groups served as control.

Evaluation of the IgG4 in Egyptian bancroftian filariasis.

The IgG4 response against antigen extracts from Wuchereria bancrofti microfilariae and Dirofilaria immitis adult worms was determined by ELISA in 65 Egyptian adult male patients suffering from different clinical manifestations of W. bancrofti infection. They were divided into microfilaremic (n-35) and amicrofilaremic (n = 30) and these divisions were subdivided into early asymptomatic, hydrocele and late chronic elephantiasis subgroups.
