Paired maternal/cord blood samples were tested for anti-Toxoplasma IgG or IgM antibodies using Biomerieux Micro-EIA2 IgG and IgM test kits. Of the 1503 women tested at the time of delivery, 344 (22.9%) were IgG seropositive. Three hundred and one maternal sera, including 265 that were IgG positive, were tested for IgM antibodies: 47 were found positive,(More)
The results of a prospective cross-sectional study on the anti-toxoplasma IgG and IgM specific antibody profile among blood donors in Al Ain United Arab Emirates are presented. The overall infection rate was 34%. Based on IgM specific antibody positive rate, acute toxoplasmosis was evident among 3% of the blood donors studied. The theoretical implications(More)
A synthetic peptide corresponding to the trypsin cleavage site on the 84 k protein of bovine rotavirus was synthesized (VP4-peptide). This synthetic peptide could be cleaved by trypsin and therefore possessed the enzyme binding site present on the authentic protein. Further proof that this peptide mimicks the authentic trypsin cleavage site was the specific(More)
Skin allograft rejection in Balb/c and C57BL/6J mice following experimental infection with 300 larvae of Trichinella spiralis or Trichinella pseudospiralis was studied. Skin grafts from normal C57BL/6J mice were transplanted to infected Balb/c mice and vice versa at days 3, 10, 20 and 30 post-infection. The clinical criteria for graft rejection, scarring(More)
An ELISA was developed for serological detection of Echinococcus granulosus infection in dromedary camels. Antigen B (AgB) partially purified from hydatid cyst fluid of camels or sheep naturally infected with cystic echinococcosis (CE) due to E. granulosus, as well as a recombinant antigen B product (r-AgB) were used in an ELISA to screen panels of serum(More)
Trypanosoma evansi, a protozoan parasite in the blood of camels is routinely diagnosed by finding the flagellates in the wet films or stained smear of peripheral blood, examined under a microscope. Although specific, this method is not sensitive at early stages of infection. We have tested the use of polymerase chain reaction (PCR) in the identification of(More)
Human cystic echinococcosis (CE) caused by larval Echinococcus granulosus is a zoonosis of major public health importance throughout the region comprising Arab North Africa and the Middle East. Prevalence rates are determined by epizootiological factors related to the size of stray dog population and its worm burden and to the infection rates in the(More)
