Vaccine Preperative Trial for Leptospirosis and their Pathological, Immunological Study by Serum Electrophoresis

2020 Journal of Drug Delivery and Therapeutics  
Leptospirosis is a fatal infectious disease caused by different serovars of Leptospira spirochetes affecting humans and animals. In the present study, the trials of the whole-cell killed formalin treated monovalent vaccine using Leptospira icterohaemorrhagiae and trivalent vaccine using Leptospira icterohaemorrhagiae, Leptospira louisiana, and Leptospira hebdomadis were studied. The serum electrophoresis studies were done after administration of the vaccine into the experimental albino mice

Similarly, the pathological observations were made by dissecting the virulent mice, vaccinated mice, and comparing them with the control mice. The MAT titre was also studied after the booster dose administration of the vaccinated serum. The monovalent and trivalent whole-cell killed formalin treated vaccines shows significant raise in the total proteins, albumin, globulin, α 1 globulin, α 2 globulin, β globulin and γ globulins of the serum as well as increase in significant levels in the antibody levels after the administration of the booster dose at an interval of 14 days.
