Caray is a lecturer in microbiology and her primary research interests are in the pathogenesis of important bacterial animal pathogens and in particular zoonoses.
Caray’s research focuses on the mechanisms used by these bacteria to establish infection. Particular emphasis is on how environmental factors, such as iron, regulate gene expression and the importance of these mechanisms in the infection process. How these mechanisms can be exploited for use as novel vaccines and diagnostic test candidates is also a feature of her research.
Caray has a particular interest in Corynebacterium, Streptococcus and Mycoplasma genera of bacteria. The genus Corynebacterium includes several pathogens for example: Corynebacterium diphtheriae (the causative agent of diphtheria), Corynebacterium ulcerans (an emerging zoonotic pathogen) and Corynebacterium pseudotuberculosis (causative agent of caseous lymphadenitis in livestock, as well as ulcerative lymphangitis in horses and lymphadenitis in humans). Of the Streptococcus and Mycoplasma genera Caray’s research is focussed on the important animal pathogens S. suis, S. equi subsp zooepidemicus (both zoonoses) and Mycoplasma cynos (a pathogen of dogs).
