We demonstrated the presence of lectins binding to glucose and N-acetylglucosamine on the surface of Conidiobolus obscurus spores by using glycosylated serum albumins substituted with fluorescent dyes and colloidal gold. The role of these exocellular lectins was examined in relation to the adhesion of the fungal spores to their host insect and the pathogenicity of the fungus.

Haemophilus pleuropneumoniae is the etiologic agent of a serious respiratory disease of swine known as porcine Haemophilus pleuropneumonia. There is some evidence suggesting the role of the capsule as a virulence factor in the pathogenesis of the organism and recent investigations have demonstrated and compared the appearance of the capsule in both virulent and avirulent strains by several mucopolysaccharide stains. Our own investigations have demonstrated variability in capsular sensitivity to the hydrolytic enzyme, neuraminidase which cleaves n-acetyl neuraminic acid (sialic acid) from mucins, including those found in several types of bacterial capsules. In an effort to localize the sites of neuraminidase sensitivity within the capsule and to possibly develop a scheme to quantitate the degree of neuraminidase sensitivity among differing serotypes and between cells of similar serotypes grown on complex and chemically defined medium, affinity cytochemistry utilizing colloidal gold-labelled neuraminidase was employed.
