My research interests are focused on molecular studies of Streptococcus equi, Streptococcus zooepidemicus and Leptospira interrogans.

S. equi causes strangles, a contagious infection of the upper respiratory tract of horses. S. zooepidemicus is responsible for metritis in mares and aggravates lower respiratory tract infections as an opportunistic invader following virus infection. At present I am involved in two projects relevant to these pathogens. The first is aimed at identification and analysis of protective antigens of S. equi; the second is genome sequencing of S. zooepidemicus W60.

Leptospirosis is a continuing threat to the horse breeder causing loss due to abortion and stillbirth. Chronic infection may lead to recurrent uveitis, a major cause of equine blindness. Control refers both to antibiotic prophylaxis and management based on identification of seropositive animals by MAT and detection of leptospira in body fluids using FA and culture. Presently I am developing more simple, reliable and rapid methods such as ELISA for identification of seropositive animals and PCR for detection and identification of leptospira in body fluids.


Projects
  1. Immunogenically active proteins of S. equi.
  2. Genome of S. zooepidemicus W60.
  3. Development and evaluation of ELISA and PCR for diagnosis of leptospira infection in horses.
