the aim of this study was to determine the seroprevalence of toxoplasma gondii in mares and stallionsin the province of ankara. sera from 168 clinically healthy horses were tested for the presence oftoxoplasma gondii antibodies using the sabin feldman dye test. toxoplasma gondii infection wasdetermined in 62 (36.9%) of 168 horses with the titers ranging from 1:16 to 1:256.

After exposure to the oral poliovirus vaccine (OPV), immunocompetent persons excrete poliovirus (PV) vaccine strains for a limited period. In contrast, immunodeficient individuals remain sometimes chronically infected, and in some cases, PV excretion times as long as 10 years have been reported. During prolonged replication in the human intestine, the PV vaccine strain almost invariably reverts...

This thesis presents a new technique for the reconstruction of a smooth surface from a set of 3D data points. The reconstructed surface is represented by an everywhere 1 C -continuous subdivision surface which interpolates all the given data points. And the topological structure of the reconstructed surface is exactly the same as that of the data points. The new technique consists of two major ...

The results of an international comparative study of the neurovirulence of oral poliomyelitis vaccines in three species of Old World Monkeys, viz. Macacus irus (cynomolgus), M. mulalla (rhesus) and Cercopithecus aelhiops (vervet) are pre3ented. The greate~t sensitivity to Sabin poliovaccine types 1 and IIr was shown by cynomolgus monkeys, followed by rhesus and vervet monkeys, whilst vervet mon...

A cassette vector has been constructed which allows the rapid and extensive modification of one of the neutralizing antigenic sites of the Sabin 1 poliovirus vaccine strain, P1/LSc 2ab. Unique restriction endonuclease sites flanking antigenic site 1 have been engineered into a full-length infectious Sabin 1 cDNA clone with minimal alteration to the coding sequence. This facilitates replacement ...

We derive a geometric criterion for the convexity of Powell-Sabin interpolants and present a multivariate generalization.

Figure 1. Fluctuation of capsid protein homology to Sabin 2 and viral stool excretion in serial stool samples from the paralysis case-patient (PC, left) and the asymptomatic contact with prolonged excretion (AC3, right). Time of sampling is included in the x-axis; homology percentage with respect to original Sabin 2 strain (X00595) and viral load in stools are in y-axis, left and right, respect...
