An indirect enzyme-linked immunosorbent assay (ELISA) and a dot enzyme assay (DEA) were used to determine the specificities of Cryptococcus neoformans factor sera to serotype type-specific capsular polysaccharides, glucuronoxylomannans (GXMs). Pure and chemically characterized GXMs were obtained from representative isolates of C. neoformans serotypes A, B, C, and D. Distinctive specificity patt...

With eight of 32 sera significantly higher estimations of anti-D concentration were obtained when test cells premodified with bromelin were used instead of bromelin as a reagent added to the reaction manifold. With one serum the difference in estimation, using the two techniques, revealed a ten-fold discrepancy. The consequences of these findings are discussed in relation to the use of the Auto...

Increased total antigen amounts of cathepsin D in breast tissue have been reported to be associated with increased disease recurrence, more frequent metastasis, and increased mortality in breast cancer patients. In the present study, Western blotting analysis has been used for the first time to determine the relative amounts of precursor and processed forms of cathepsin D in sera and breast tis...

Serovars of Lisreria l1Iollocyrogelles were determined. Sera of aborted samples (200) were collected from different hospitals in Tehran and were tested serologically by immunofluorescent antibody methods (IF tests). 137 positive sera were identified. Positive sera were tested against 12 serovars of Listeria l1Iollocytogelles separately. Titers of antibody in patients' sera for all serovars ...

1. Antibodies to slime molds were produced by injecting D. discoideum and D. purpureum amebas from 48 hour cultures into rabbits. 2. Anti-D. discoideum and anti-D. purpureum sera caused agglutination of homologous amebas from 24 to 26 hour cultures, agglutination of certain heterologous amebas from 30 to 36 hour cultures, and agglutination of all heterologous amebas from 43 to 48 hour cultures....

A rare variant (-D-/-D-) in two generations due to consanguineous marriage was reported. The propositus (T.M., 27 years of age) delivered her second baby who suffered from severe jaundice. She had agglutinin of titer 1:64 in saline and 1:1,024 in Coomb's test against red cells of her husband (CDe/cDE). Family study revealed that T.M.'s father and his two siblings were grouped as -D-/-D-. Each o...

BACKGROUND The Northern part of Serbia is hyperendemic-endemic for canine dirofilarioses. Considering this fact, many human dirofilarial infections could be expected, however only about 30 cases in Serbia have been described until today. Aims of this survey were to assess the people reactivity to the antigens of D. repens and D. immitis and to identify risk factors for the contact exposure. M...

Specific IgE to proteins from Tribolium confusum (TC), a flour beetle, was detected in 9/125 sera of subjects exposed to rye and wheat flour. TC RAST was not inhibited by Dermatophagoides pteronyssinus, rye or wheat flour. Immunoblot experiments showed specific binding to three proteins from adult TC or pupae, not present in rye or wheat flour. These findings suggest that TC might act as an occ...

The purpose of this study was to evaluate the protective efficacy a vaccine consisting recombinant Neospora caninum-cyclophilin (NcCyP) and -profilin (NcPro) in sheep. At 42 d 21 prior mating, adult Dorset ewes were immunized with rNcCyP-rNcPro (Group 1) or co-purifying non-recombinant (NR) control 2). 90 days post-mating, all challenged by intravenous injection 106 Nesopora caninum Illinois ta...
