1961Okabe & Goto in Bull. Faculty Agric. Shizuoka Univ. No. 11. 42/1 The presence of physiologically specialized strains or pathotypes. 1965Ann. Appl. Biol. LVI. 35 A possible explanation of the apparent inability of resistant S[olanum] nigrum to select out pathotypes that reproduce freely upon it in the field is that potato crops encourage the multiplication of far too many nematodes incompatible with S. nigrum. 1972Farmers Weekly 21 Apr. p. xiii/4 The fear in Britain is that if the frequency of cropping is increased greater selection pressure will result in more of eelworm pathotypes not affected by present resistant varieties. 1973Avian Dis. XVII. 360 Antibodies to Newcastle disease virus of an unknown pathotype have been detected repeatedly in migratory geese and ducks. 1988Ann. Inst. Pasteur: Microbiol. CXXXIX. 198 This work has attempted to evaluate the efficiency of a set of DNA probes for characterizing the various pathotypes of E. coli isolated from diarrhoeal stools. |
