Résumé
Meat-borne parasites are Sarcocystis species, Toxoplasma gondii, Taenia saginata, Taenia solium and Trichinella spiralis. A total of 300 animals including 100 cattle, 100 goat, and 100 pigs, slaughtered in El-Minia governmental slaughterhouses. From each animal, five samples were taken from different muscles [esophageal, tongue and cardiac] and different organs [liver and brain]. Meat samples were examined macroscopic and microscopic [direct, homogenization and H and E staining] for detection of the above-mentioned parasites. Serum samples were subjected to IHA for detection of T. gondii specific antibodies. This study revealed that Sarcocystis species were the highest parasites that could be detected, with overall prevalence of 80%, which was statistically significant [P

This study investigated the effect of breast-feeding in protection against protozoan infection in infants with persistent diarrhea. Infants were classified into 2 groups; 161 breast-fed infants and the same number of non-breast-fed infants. Microscopic examinations of stool were done for detection of parasites and measuring the intensity of infection. Moreover, serum levels of IgE and TNF-alpha were measured by ELISA. Cryptosporidium spp., Entamoeba histolytica/Entamoeba dispar, Giardia lamblia, and Blastocystis sp. were demonstrated in infants with persistent diarrhea. The percentage of protozoan infections was significantly lower in breast-fed infants than that in the non-breast-fed infants. The levels of IgE and TNF-alpha were significantly lower in the breast-fed group than in the non-breast-fed group. There were significant positive associations between the serum levels of IgE and TNF-alpha and the intensity of parasite infection in the breast-fed group. It is suggested that breast-feeding has an attenuating effect on the rate and intensity of parasite infection.
