Natural entamoeba histolytica infection in domestic animals and rodents in Dakahlia Governorate, Egypt

The prevalence of Entamoeba histolytica was estimated in 112 cows, 85 buffaloes, 57 sheep, 46 goats, 148 dogs and 224 rats. Natural infection was detected in one dog and 43 rats. The relatively high prevalence of amoebic infection in Rattus norvegicus [31.94%] suggests its possible epidemiological role in the dissimination of amoebiasis in Dakahlia Governorate

Helminth fauna of rats from Dakahlia Governorate, Egypt

Two hundred ninety-five rats [206 Rattus. rattus and 89 Rattus norvegicus] collected from different areas of Governorate were surveyed for helminth parasites. Thirteen species of helminths were observed in 287 [97.3%] of them. Multiple infections were common. Eight rats were parasite-free. The epidemiological role of these rats was discussed

Malarial antibodies and parasitaemias in immunosuppressed mice

Parasitaemia and antibody levels were followed in mice receiving cyclophosphamide [an immunosuppressive agent] and in a control group of mice, after the intraperitoneal inoculation of a standard dose of Plasmodium berghei yoelii. The drug caused impairment in both recovery from infection and antibody synthesis. In both groups of animals significant increase in antibody levels coincided with a decrease in Parasitaemia was noticed, suggesting that the humoral factor is essential in the recovery process
