Associate Professor Keren Dittmer PhD, BVSc, Diplomate ACVP

Associate Professor and Team manager (Veterinary Pathology)

Doctoral Supervisor
School of Veterinary Science

After graduating with a Bachelor of Veterinary Science from Massey University, New Zealand in 2001, Keren spent 4 years in large and small animal practice in New Zealand and the United Kingdom.  In late 2005 she returned to Massey University to do a PhD on inherited rickets in Corriedale sheep, and this was completed in 2008. She is a diplomate of the American College of Veterinary Pathologists and is currently an Associate Professor in both anatomic and clinical veterinary pathology, as well as team manager of pathobiology in the School of Veterinary Science at Massey University. Keren has a particular interest in skeletal pathology, vitamin D and genetic diseases, and has published more than 50 peer-reviewed articles in these areas.  She is a co-author of the Bone and Joints chapter in the 6th edition of Jubb, Kennedy & Palmer’s Pathology of Domestic Animals, the Tumors of bone chapter in the 5th Edition of Tumors of Domestic Animals and the Genetic Diseases of Cattle chapter in the 2nd Edition of Diseases of Cattle in Australasia, plus the author of the Metabolic Bone diseases chapter in the 1st Edition of Small Animal Medicine. She is an Editorial Adviser for the Journal of Comparative Pathology.  Keren was secretary for the NZ Society for Veterinary Pathology for 7 years before retiring in 2019, and was secretary of the International Veterinary Pathology Coalition 2019-2020.

Keren is an Associate Professor in Veterinary Pathology.  She has a particular interest in skeletal pathology, vitamin D, and genetic diseases.  She has published numerous papers in this area and written 6 book chapters.

Project Title: Feline haemoplasma infections in New Zealand

Haemoplasmas are small bacteria that sit on the surface of red blood cells and infect a wide variety of mammalian species, including humans. Haemoplasma infection in cats has the potential to cause a severe, life threatening anaemia. Three haemoplasma species have been identified in cats, Candidatus Mycoplasma haemominutum (CMhm), Mycoplasma haemofelis (Mhf) and Candidatus Mycoplasma turicensis (CMt), each with variable ability to cause disease, response to antimicrobial therapy and ability to form a carrier state. The aim of this study was to evaluate feline haemoplasma prevalence, and determine any associations between haemoplasma infection and possible risk factors, in a convenience sample of New Zealand domestic cats. DNA was extracted from 200 surplus feline blood samples submitted to a diagnostic laboratory for routine haematology over a 12 month period. Testing identified 62 cats (31 %) that were positive for haemoplasma DNA; 49 (24.5 %) for CMhm, 15 (7.5 %) for Mhf, and 9 (4.5 %) for CMt. Twelve of the positive cats had dual infections; 11 CMhm/Mhf and one CMhm/CMt. Twenty cats (10 %) were feline immunodeficiency virus (FIV) positive and 11 cats (5.5 %) were feline leukaemia virus positive. Positive FIV status, male gender and non-pedigree breed were significantly associated with haemoplasma infection. The results of this study demonstrate that New Zealand feline haemoplasma prevalence correlates with previous overseas studies, with CMhm being the most common infection. This is the first report of CMt in New Zealand.
