Specificity in curing by heteroimmune superinfection
Virology, 1970Abstract Superinfection of a lysogenic bacterium with heteroimmune phage can result in loss of the resident prophage-curing. Curing is attachment-site specific, and examination of the curing properties of ten classes of 21-λ hybrids implies that all the genes carrying site specificity in curing lie between susB and cIII . The products of both the

Superinfection and the evolution of parasite virulence
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1994Earlier ideas that parasites evolve toward becoming harmless to their hosts have, in recent years, given way to more analytic studies, focused on the 'basic reproductive rate', R0, of individual parasites. In general, the biology of the parasite life cycle will lead to constraining relations between virulence (parasite-associated host death or ...

Archives of Dermatology and Syphilology, 1940
T.B., a man aged 44, was first seen in June 1938. Six years previously he had had an initial lesion, for which he had received some irregular treatment with an arsenical and a bismuth compound. The Wassermann reaction of the blood was strongly positive. Physical examination gave essentially negative results.

[Superinfection in heterakiasis].
Veterinarno-meditsinski nauki, 1980Experiments including single, two-fold and triple superinvasions with 100 invasive heterakidic eggs each on 2 day- and 4 month-old chickens were carried out (beginning of the experiment). Single superinvasions were effected on the 12th, 18th and 30th day, two-fold superinvasions -- on the 12th and 18th, 12th and 30th, 18th and 30th day, while triple ...
