Emeritus Professor and Professor of Veterinary Microbiology

About me

I am an Emeritus Professor at Murdoch University, and formerly was the Dean of Veterinary and Life Sciences and Professor of Veterinary Microbiology.

My research has focused on intestinal spirochaetes of the genus Brachyspira, and the diseases they cause. I am still working on developing new vaccines and diagnostic tests for these bacteria for use in controlling disease in pigs and poultry.

Google Scholar lists my h-index as 59 and my i10-index as 212. I have > 11,600 citations.

Teaching area

I have lectured in Veterinary Virology, Veterinary and Animal Bacteriology and in Medical Bacteriology.

I have supervised 28 honours students, 15 of whom have received first class honours.


Research areas

I have a long history of studying the epidemiology and control of infectious diseases of livestock, and in recent years have moved more into the development and commercialisation of novel diagnostics and vaccines. My research has centred around three main themes:

i) Studies on the disease associations, molecular epidemiology, population genetics and population structure of pathogenic bacteria, particularly involving definitive studies on intestinal spirochaetes of the genus Brachyspira (formerly Serpulina). This genus includes important pathogenic species, particularly of pigs and poultry. Notable outcomes include the identification, naming and improved understanding of a number of new pathogenic Brachyspira spp. that infect human beings and various species of animals and birds. We were the first group to sequence and publish descriptions of the full genomes of the two major pathogenic Brachyspira species (B. hyodysenteriae in March 2009 and B. pilosicoli in July 2010).

ii) Studies on interactions that occur in the gastrointestinal tract between enteric bacterial pathogens and dietary components, including consideration of effects on the intestinal microenvironment and on intestinal structure and function. These “nutritional intervention” studies have been directed by the need to find alternatives to antibiotics to control enteric bacterial infections in pigs and chickens.

iii) Most recently I have been working on developing novel recombinant vaccines for the control of Brachyspira infections in pigs and chickens. This has involved using a whole genomic sequencing and bioinformatics approach (“reverse vaccinology”) to identify potential vaccine candidates from bacterial species of interest (currently Brachyspira hyodysenteriae, B. pilosicoli and B. intermedia). Following sequencing and genomic annotation, the work includes producing, evaluating and then testing selected recombinant proteins for their immunogenicity and efficacy. The studies include functional genomics and evaluation of novel vaccine delivery systems. So far this work has led to the preparation of 11 patents, and ultimately should result in the availability of new commercial vaccines for Brachyspira infections in pigs and poultry. Selected antigens also are being evaluated for commercial serological tests for these infections, and a licensing agreement for a new diagnostic ELISA that we have developed is in the process of being finalised.

Collaborations, and links with Industry

An important feature of my work has been the development of research collaborations with colleagues in Australia, and in Europe, the USA and parts of Asia.  I have made strong collaborative links with industry, and have also helped establish a spin out company (Spirogene) to develop new veterinary vaccines/diagnostics company with commercial partners. Financial support for my research has also come from State and National funds contributed to by the Australian Pig and Poultry Industries, and the Rice Industry, as well as from other Government funding bodies (the Australian Research Council and the National Health & Medical Research Council).

 

Current projects

I am currently working on the development of vaccines and novel diagnostics for Brachyspiral infections in pigs and poultry.
