Haematological changes in dogs infected with ancylostoma duodenal

A definite relation between the intensity of Ancylostoma duodenale and hematological changes in dogs was studied. There was a relation between the increase in egg count with the hemoglobin percentage. The present study reported hematological data collected during the acute phase of experimental infection with A. duodenale

Immune response in dogs infected with ancylostoma duodenal

The relation between the level of serum immunoglobulins [IgG, IgM, IgA and IgE] percentage of T-lymphocyte and egg counts was studied in dogs infected with Ancylostoma duodenale. The serum IgG levels were significantly high, and a marked significance was noticed also in the levels of IgM and IgE. An inverse relationship between the concentration of IgG and egg count, and a direct association between the percentage of T-lymphocyte and IgG level were proved

Immunization against experimental trichinosis using T spiralis larvae and hydatid fluid antigens

Immunization of mice against T. spiralis infection using T. spiralis larval glycoproteins as homogenous antigen and crude hydatid fluid as heterogenous antigen showed a marked reduction in larva burden and a significant rise of serum IgE in immunized mice infected with T. spiralis larvae as compared with control group. More reduction was observed with immunization with homogenous T. spiralis larval antigen compared with heterogenous hydatid fluid antigen. The reduction in larval burden with rise of serum IgE begins after the third week of immunization

Some immunological studies on amoebiasis

Studies of immunoglobulins pattern in 64 patients with different clinical symptoms of amoebiasis revealed that IgG showed no rise in patients with acute amoebic dysentery and asymptomatic cyst passers, while it was significantly increased in patients with active hepatic amoebiasis. IgM, IgA and IgE were significantly increased in both acute amoebic dysentery and active hepatic amoebiasis, but no significant changes in asymptomatic cyst passers. ELISA [depended on level of IgG] was valid and reliable in diagnosis of active hepatic amoebiasis [100%], IHAT [depended on level of IgM] gave 72.7% and 46.9% in patients with acute amoebic dysentery and active hepatic amoebiasis, respectively

Histopathological picture of two cases of ectopic fascioliasis in Mansoura, Dakahlia

Two cases of ectopic fascioliasis were reported. The first case was detected in a hematoma in the anterior abdominal wall in a diabetic patient, the second was in an abscess in the upper part of the thigh. The clinical and laboratory findings were discussed

Axenic growth in vitro of ancylostoma duodenal to the filariform [resting] larvae

Large numbers of free-living stages of Ancylostoma duodenale can be grown in vitro on formalin-killed Escherichia coli supplemented with cholesterol and Dulbecco's minimum essential medium [DMEN]. Eggs at 28C hatched and released first-stage larvae in 24 hours. First-stage larvae molted in 36 hours at 28C. Second-stage larvae molted in 2-3 days at 28C, but retained the old cuticle. Third-stage larvae characterized by the presence of a buccal cap capsule, sheath, filariform esophagus and absence of lips. Lateral alae were observed in all free-living stages
