haemagglutination-inhibiting (hi) antibodies against strains of influenza a virus in horse and pig sera in nigeria.sera from horses and pigs obtained from lagos and ibadan respectively were examined for haemagglutination-inhibiting (hi) antibodies to two strains each of h3n2 and h1n1 subtypes of influenza a virus. more horse sera had hi antibodies to the h3n2 than the h1n1 strains while pig sera reacted almost equally with strains of both subtypes. all the horse sera had hi antibodies to the two strains of h3n2 subtype (a/mississippi/1/85 and a/leningrad/360/86), while 87% and 14% of the horses examined were ...19902100750
patterns and properties of haemagglutinins expressed by shigella serogroups in lagos, nigeria.forty-five strains of shigella were screened for haemagglutinin production and broad-spectrum haemagglutination reaction. mannose-sensitive haemagglutinin (msha) was found in 22 strains [shigella flexneri (7), s. dysenteriae (7), s. sonnei (3), and s. boydii (5)]. eighteen strains harboured mannose-resistant haemagglutinin (mrha), and 8 strains were observed to be non-haemagglutinating to guinea pig erythrocyte. with the exception of human erythrocytes (o, a, b, and ab), the observed msha and mr ...200313677435
