Antigenic variants of rabies virus

Antigenic variants of rabies virus

The authors studied nineteen street virus isolates from different regions of Canada using either anti-nucleocapsid and anti-glycoprotein monoclonal antibodies or cross-protection tests. This study only allowed us to recognize three groups of viruses with different nucleocapsid patterns, and no difference, as far as protection with a Pitmann-Moore vaccine is concerned, between four of these stra...

Epidemiology of Antigenic and Genetic Variants of African Rabies Viruses

This brief review is intended as a bridge between rabies virologists and molecular biologists on the one hand, and field veterinarians on the other who are involved in the control of rabies in sub-Saharan Africa, particularly those in southern Africa. An attempt is made to provide people with limited exposure to molecular approaches to epidemiological investigation and who are unlikely to have ...

Antigenic variation between rabies virus strains and its relevance in vaccine production and potency testing

Antigenic Variants of Eastern Equine Encephalitis Virus

A study by hemagglutination-inhibition test showed that 19 strains of eastern equine encephalitis virus grouped themselves in two main types, which have been designated North American and South American. The former consists of ten strains from the eastern half of the United States, from Massachusetts to Florida; Jamaica, the Dominican Republic, and, subject to confirmation, Thailand. The South ...

Antigenic Variants of Influenza A2 Virus.

From 1967 to 1971 little antigenic variation was detected in the prevalent influenza B viruses but in December 1972 a new antigenic variant of influenza B was isolated in Hong Kong from sporadic cases of influenza. The new variant, B/Hong Kong/5/72, possessed a haemagglutinin antigen which showed considerable antigenic differences from that of former influenza B strains while its neuraminidase ...
