Analysis of plasma proteins avidly bound to T. pallidum surfaces revealed the ability of T. pallidum to acquire numerous host macromolecules. No acquisition was evident by the avirulent spirochete, T. phagedenis biotype Reiter. Western blotting technology using hyperimmune antifibronectin serum as a probe revealed the ability of virulent treponemes to avidly bind fibronectin from a complex medi...

In order to identify immunoreactive Bartonella henselae proteins, B. henselae antiserum from an experimentally infected cat was used to screen a B. henselae genomic DNA expression library. One immunoreactive phage clone contained a gene (p26) with significant nucleotide identity with orthologs in brucellae, bartonellae, and several plant-associated bacteria. p26 gene sequences from four B. hens...

Viral haemorrhagic disease (VHD) of rabbits is an acute entity with high mortality which affects adult rabbits. Several vaccines have been developed in China and extensive use of these vaccines in the field has controlled the spread of the disease. Formalin inactivated tissue vaccine induces solid immunity on the third to fourth day post vaccination and immunity lasts for at least six months. T...

The infection mechanism of vaccinia virus is largely unknown. Neither the attachment protein of extracellular enveloped virus (EEV), the biologically relevant infectious form of the virus, nor its cellular receptor has been identified. Surprisingly, all former attempts using antibodies to block EEV infection of cells in vitro had failed. Here, we report the production of an anti-envelope hyperi...

Objectives This is a protocol for Cochrane Review (intervention). The objectives are as follows: To assess whether convalescent plasma or hyperimmune immunoglobulin transfusion effective and safe to prevent infection with SARS?CoV?2 development of COVID?19; maintain the currency evidence, using living systematic review approach.

We show that every real low for Demuth randomness is of hyperimmune-free degree.

Although it has often been speculated that Interleukin (IL) 1 alpha and IL 1 beta are circulating endogenous pyrogens (EP), there are few data demonstrating an elevation of these cytokines in the plasma of febrile animals. We hypothesized that IL 1 is released locally and may act to stimulate the release of another pyrogen, IL 6, which circulates to the brain to cause fever. The major purpose o...

The two serotyping schemes for the detection of heat-stable antigens of Campylobacter jejuni and Campylobacter coli use the same strains for antiserum production but differ in the detection systems used for identifying agglutination. The Penner method uses passive hemagglutination (PHA) while the Laboratory of Enteric Pathogens method uses the same antisera but in a whole-bacterial-cell direct ...
