FIG. 1.

Genetic map of the adhesin gene lppS and part of the lppT gene. The upper line shows the scale in kilobase pairs (kb) and the position of the restriction enzyme cutting sites for HindIII (H) and EcoRI (E). The bold line represents the position of the lppS gene probe. The boxes represent the coding sequences for the proteins LppS and part of LppT. The arrowhead of the box gives the direction of transcription and translation. The grey part of the box represents the serine-rich domain of LppS. The region between the broken lines shows the amino acid sequence, derived from the DNA sequence, of the variable domain of LppS of type strain HRC/581 and of two field strains of M. conjunctivae. This part of the gene was used for the subtyping of M. conjunctivae strains. Identical amino acids are shown on black background.
