Similarities in size between hemin-binding protein 1 (HmBP1) and transferrin-binding protein 1 (TBP1) of Neisseria meningitidis suggest that these proteins are functionally homologous. However, a meningococcal mutant lacking the transferrin-binding proteins retained the capacity to acquire iron from heme and hemoglobin. In immunoblots, hyperimmune polyclonal antiserum against TBP1 did not react...
BACKGROUND & OBJECTIVE Early diagnosis is the key to the treatment of leptospirosis. For development of rapid diagnostic kits, a thorough knowledge about the nature of the proteins expressed by the pathogen during infection is necessary. The present study was undertaken to understand the nature of immunoreactive proteins from commonly circulating serogroups of Leptospira in the endemic Andaman ...
The nucleocapsid (N) protein of rinderpest virus (RPV) is one of the most abundant and immunogenic viral proteins expressed during natural or experimental infection. To identify immunogenic epitopes on the N protein, different forms of RPV N protein, including the full-length protein (N(1-525)), an amino-terminal construct (N(1-179)), and a carboxy-terminal construct (N(414-496)), were expresse...
Alpha-toxin, the major cytolysin of Staphylococcus aureus, preferentially attacks human platelets and cultured monocytes, thereby promoting coagulation and the release of interleukin-1 and tumor necrosis factor. Titers of naturally occurring antibodies in human blood are not high enough to substantially inhibit these pathological reactions. In the present study, F(ab')2 fragment preparations fr...
Hyperimmune globulins were reported to prevent and treat fetal cytomegalovirus (CMV) infection during pregnancy. Here, we report that infusions of standard human intravenous immunoglobulin significantly increase CMV IgG titers and avidity indexes in pregnant women, paving the way to their use for passive transfer of maternal CMV humoral immunity to fetuses. Preliminary data on perinatal outcome...
Passive transfer of humoral immunity to experimental syphilis in rabbits was accomplished with large doses of hyperimmune serum. When the serum was administered before inoculation of Treponema pallidum, the onset of chancres was delayed; when it was given early in the course of infection, a transient period of arrest and healing of the chancres was imposed.
