In December 1998, a 37‐year‐old Queensland woman died from a rabies‐like illness, 27 months after being bitten by a flying fox (fruit bat). Molecular techniques enabled diagnosis of infection with Australian bat lyssavirus (ABL), the second human case to be recognised and the first to be acquired from a flying fox. It must be assumed that any bat in Australia could transmit ABL; anyone bitten or scratched by a bat should immediately wash the wounds thoroughly with soap and water and promptly seek medical advice.
Monospecific antisera against BCG antigen 60 were produced by all of four rabbits during immunization with precipitates containing antigen 60 cut out of gels after crossed immunoelectrophoresis. During electrolytic iodination of a crude antigen 60 preparation, preferential labeling of antigen 60 was demonstrated, and a specific radioimmunoassay was established to follow the development of anti-BCG-60 activity during immunization.
Monospecific antisera against four different antigenic components of Mycobacterium bovis (BCG) were produced by immunization of rabbits with precipitates cut out of gels after crossed immunoelectrophoresis (CIE). An important feature is to use a semipurified mycobacterial antigenic preparation, or a cross-reactive antigen, to obtain a simpler pattern in CIE so that a clean precipitate, free from contaminating antigens, can be obtained for immunization. The findings with one particular antigen are shown, and the use of such antisera is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
