Many pathogenic bacteria exist in nature as multiple antigenic types or serotypes, meaning that they are variant strains of the same pathogenic species. For example, there are multiple serotypes of Salmonella typhimurium based on differences in cell wall (O) antigens or flagellar (H) antigens.any pathogenic bacteria exist in nature as multiple antigenic types or serotypes, meaning that they are variant strains of the same pathogenic species.

Abstract. Alterations in peripheral blood lymphocyte subpopulations were examined in bovine leukosis virus (BLV)-infected cattle using antibodies specific for differentiation antigens in conjunction with analytical flow cytometry.Animals considered to be aleukemic and lymphocytotic were included in the study.ignificantly fewer numbers of circulating B-lymphocytes (surface Ig-positive) and T-helper lymphocytes (BoCD4-positive) were identified in BLV-infected aleukemic cattle compared to non-infected controls while no significant differences were established for T-cytotoxic/suppressor lymphocytes (BoCD8-positive).
