A rapid, quantitative assay of interferon was developed, based on the reduction of the number of virus-infected cells by dilutions of interferon. Infected cells were enumerated by fluorescent cell-counting 24 hours after challenge of interferontreated McCoy cover-slip cell monolayers. A quantitative linear relationship between the reduction of fluorescent cells and dilutions of interferon was d...

We provide serological evidence of lyssavirus circulation among bats on southwestern Indian Ocean (SWIO) islands. A total of 572 bats belonging to 22 species were collected on Anjouan, Mayotte, La Réunion, Mauritius, Mahé and Madagascar and screened by the Rapid Fluorescent Focus Inhibition Test for the presence of neutralising antibodies against the two main rabies related lyssaviruses circula...

Pseudoviruses are useful virological tools because of their safety and versatility; however the low titer of these viruses substantially limits their wider applications. We developed a highly efficient pseudovirus production system capable of yielding 100 times more rabies pseudovirus than the traditional method. Employing the high-titer pseudoviruses, we have developed robust in vitro and in v...

Introduction: Despite the effective preand post-exposure treatments, at least 60,000 deaths from rabies occur worldwide every year. Post-exposure treatment is considered as one of the most significant measures for preventing human deaths in exposed individuals. The 2-1-1 rabies post-exposure treatment schedule known as Zagreb regimen is an abbreviated immunization plan in which a tissue culture...

PURPOSE Myeloid differentiation factor 88 (Myd88), a ubiquitous Toll-like receptor adaptor molecule, has been reported to play important roles in B cell responses to infections and vaccination. The present study evaluated the effects of genetic adjuvanting with Myd88 on the immune responses to a plasmid DNA rabies vaccine. MATERIALS AND METHODS Plasmids encoding rabies glycoprotein alone (pIR...

Between August 1993 and September 1994 we documented serological responses of coyotes (Canis latrans) vaccinated with two commercial rabies vaccines licensed for use in domestic dogs. Serologic responses were documented by testing for rabies virus neutralizing antibodies with the rapid fluorescent focus inhibition test (RFFIT) at 30, 90, 180, 270, and 365 days post-vaccination. All coyotes vacc...

The recently discovered (1976) Ebola virus is responsible for one type of human hemorrhagic fever on the African continent (10). The virus is highly pathogenic, and no vaccine is available; therefore, it is classified as a class 4 viral agent (2). We initiated a program to investigate the ecology, biology, immunology, and chemistry of this virus and its relatives, and have recently reported on ...

BACKGROUND The rabies virus causes a fatal encephalitis and can be transmitted through organ transplantation. In 2013, a man developed rabies 18 months after receiving a kidney from a donor with rabies, who was not known to have been infected when the organs were procured. Three additional persons who received organs from the same donor (liver, kidney, heart), all of whom were not vaccinated fo...

We performed a cross-sectional study including 533 individuals (median age 61) from the highly TBE endemic Åland Islands in the archipelago between Sweden and Finland. Blood samples, questionnaires and vaccination records were obtained from all study participants. The aim was to investigate if there was any association between TBEV antibody titer and 12 health-related factors. Measurement of TB...

Recombinant antibody phage display technology has been used to mimic many aspects of the processes that govern the generation and selection of high-affinity natural human antibodies in the human immune system, especially for infectious disease prophylaxis. An anti-rabies virus immunized phage-display Fab library was constructed from peripheral blood lymphocytes from vaccinated volunteers. The i...
