Temperature-sensitive mutants of type 5 adenovirus belonging to eight complementation groups were complemented in mixed infection by type 12 adenovirus, whereas mutants of 7 other groups were not enhanced. In some crosses, phenotypic mixing took place. No evidence of recombination between type 5 ts mutants and type 12 was found.

For purposes of gene therapy, the tropism of adenovirus (Ad) serotype 5 vectors can be altered with fibers derived from alternative serotypes. However, there is currently limited information available on the cellular receptors used by the approximately 51 known Ad serotypes. Recently, alpha(2-->3)-linked sialic acid (2,3-SA) has been implicated as the cellular receptor for wild-type Ad37. Howev...

Although limited almost exclusively to military trainees, acute respiratory disease (ARD) caused by adenovirus types 4 and 7 had been the leading cause of hospitalization in U.S. Army personnel. This decrease which resembles influenza in clinical manifestations led to hospitalization of as many as 50% of military trainees in midwinter and imposed a heavy burden on military hospitals and trainin...

Bayesian analyses of spatial data often use a conditionally autoregressive (CAR) prior, which can be written as the kernel of an improper density that depends on a precision parameter tau that is typically unknown. To include tau in the Bayesian analysis, the kernel must be multiplied by tau(k) for some k. This article rigorously derives k = (n - I)/2 for the L2 norm CAR prior (also called a Ga...
