Abstract
Tick gut glycoprotein, designated as Bm86, found on the luminal surface of the plasma membrane of gut epithelial cells of Boophilus microplus, which is a concealed antigen, has been used as vaccine candidate molecule for immunization against ticks. To better understand the molecular diversity of Bm86 gene in ticks, a portion of the cDNA was sequenced from an Indian isolate of B. microplus. Comparison of nucleotide sequence revealed that Indian isolate had 97 % homology (18 polymorphisms) with that of the Australian isolate and 96 % homology (20 polymorphisms) with that of the Cuban vaccine strain. Further, the Indian isolate differed from the Cuban vaccine isolate at 7 amino acid loci, including 5 substitutions (at residues 88, 94, 175, 176 and 177) and 2 deletions (at 183 and 184). However, protein prediction studies did not show any difference in the putative antigenic epitopes of the protein expressed.
