    Professor Sam Abraham
    BSc, MSc, PhD

    Professor in Microbiology

    About me

    I grew up in Kerala, in the south west of India. In 2006, I received my BSc, in Zoology from Mahatma Gandhi University in Kerala. Shortly after, I moved to Australia in pursuit of higher education and joined the University of Wollongong to undertake a Masters in Biotechnology. Subsequently, I completed a PhD in Micro and Molecular Biology from  the University of Wollongong (2012) undertaking my research at the Elizabeth Macarthur Agricultural Research Institute, New South Wales Department of Primary Industries. In 2012, I moved to the University of Adelaide, to undertake a post-doctoral research fellowship in Antimicrobial Resistance with Prof. Darren Trott. Along with Prof. Trott, I established the First National Network on Antimicrobial Resistance Surveillance in Australian Animals. In 2015, I joined Murdoch University as an academic lecture in microbiology.
    I run the antimicrobial resistance and infectious diseases (AMRID) laboratory at Murdoch University. www.amrid.com.au

    Teaching area

    I teach veterinary and medical microbiology and antimicrobial resistance at Murdoch University.

    Research areas

    I have been undertaking research in the area of “One-Health AMR” with a specific focus on controlling resistant zoonotic pathogens from Australian animals. I utilise conventional microbiology and next generation sequencing, robotics and mass-spectrometry techniques along with in-vivo animal models to understand the development and spread of AMR between animals and humans. I have led technological innovations in the use of robotics and genomics for AMR surveillance on large numbers of bacterial samples from various sources.

    I have developed a strong research track record, long term collaborations with academic researchers and research engagement with the Australian livestock sector (Pigs, Chicken Meat, MLA, Australian Eggs), Australian human AMR surveillance (Australian Group on Antimicrobial Resistance; AGAR), and the Federal Department of Agriculture and Water Environment to tackle AMR from a One Health perspective. See research group website for more details

    I have extensive experience in working with Industry
    partners such as New South Wales Department of Primary Industries, Zoetis
    (formerly, Pfizer Animal Health), Novartis, International Animal Health
    Products and start-up companies working on new antimicrobials. I also work
    closely with Australian network of Veterinary Diagnostic Laboratories.

    Research highlights

    1) Emergence of Critically Important Antimicrobial (CIA) resistant (-R) bacteria in Australian livestock. When bacteria resistant to CIAs emerge in livestock, it raises public health concerns due to the potential of such resistant bacteria to cause untreatable human infections. Through large national studies, my research has demonstrated the i) emergence of CIA-R E. coli and Salmonella in Australian pigs and cattle with the detection of highly transmissible plasmid associated genes such as blaCMY-2, CTXM-1,9,14 ii) once established, CIA-R E. coli could persist for >4 years in the absence of direct selection pressure and resistance encoding plasmids could also move into potential human pathogens resulting in potential concern for public health iii) emergence of CIA-R in Campylobacter from chickens (most import zoonotic food borne pathogen in Australia).

    2) Wildlife as a source of superbugs. My research has demonstrated that Australian gulls are carriers (20%) of CIA-R E. coli capable of causing serious human infections attracting national and international press coverage. Further work also demonstrated evidence of potential leakage of CIA-resistance to other birds (pigeons, penguins) that share the same ecological niche demonstrating the need for a One health approach in tackling AMR, reported by Channel 9 (TV) and broadcasted on 38 stations.

    3) Molecular epidemiology of methicillin resistant Staphylococcus aureus (MRSA) in Australian animals. MRSA are deadly bacteria that cause serious life-threatening infection in humans. My research has demonstrated the detection and genomic characterisation of MRSA in Australian livestock, companion animals and veterinarians. We have shown that highly pathogenic MRSA clones (ST93- PVL) can enter into livestock by human-to-animal transmission and once established can transfer to farm workers causing clinical infections.

    4) Companion animals as source of CIA-R bacteria. Through a large national project, my research has shown that companion animals are carriers of CIA-R E. coli largely attributed to spiller over of human pathogens into pets. My research has also shown evidence of broader community risk due to transmission of carbapenem resistance into zoonotic species such as Salmonella (resistant to 9 classes of antimicrobials) in cats causing localised outbreak.

    5) Development of a new class of anti-infectives. My ability to deliver industry focused research outcomes and collaborative research with a range of disciplines has led to the discovery of a novel class of anti-infectives. This has led to an antiparasitic drug discovery programme in my laboratory.

    Development of a National Antimicrobial Resistance Surveillance System in Animals:
    I have played an integral part in the development of AMR surveillance systems for the Pork, Cattle and Poultry industries in Australia. In recognition of my work, I was awarded the contract for undertaking AMR surveillance in meat chickens, egg industry, cattle and pigs. These works are now completed and the reports available on respective Research and Development Corporation websites,

    I have led technological innovations in the use of robotics currently developed in my research and my collaborations and partnership with industry and government have created opportunities for broader application of my robotics systems to other industries. With the aid of a recently funded $1.8M “Rural Development for Profit” grant, my research team has developed high-throughput capacity robotics enabling cost-effective testing of AMR on large numbers of bacterial samples from livestock in the pork and chicken industries at an unprecedented level. This system will also be utilised in a number of drug discovery projects as well as the current application. However due to commercial confidentiality involving various industry partners, this work is not yet published.

    Since 2015, I have been involved as an expert advisor to the (Australian Government) Department of Agriculture, Water and the Environment (DAWE) previously DAWR, Australian Pig and Chicken industries in developing national antimicrobial resistance surveillance in Australian animals. My laboratory has been selected as one of the two reference laboratories to perform National AMR surveillance.

    Key involvement/outcomes
    • Development of Australia’s pilot National AMR surveillance in pigs, chicken and Australian eggs which will be reported to the OiE, WHO
    • Conduct of National AMR surveillance in Australian cattle
    • Performing the first AMR surveillance in E. coli and Staphylococcus causing clinical infections in Australian companion animals and livestock
    • Development of standardised AMR testing for Australian pig industry. Now adopted by Australian pig Industry as a guide for AMR and bacterial diagnostics.
    • Expert panel member for AMR strategic meetings in Dec-2014, Dec-2016, Aug-2018
