  • Food-borne pathogens and animal botulism issues surrounding the on-farm composting of layer chicken waste and mortalities – a review


  • Prevalence, genetic relationships and pathogenicity of intestinal spirochaetes infecting Australian poultry

    UME 2EAThis research aimed to: determine whether fastidious anaerobic intestinal spirochaetal bacteria, or a similar bacteria, was present in Australia; to isolate and characterise this bacteria; and to test the pathogenic potential of the disease.

  • Marek's disease research in Australia - a review

    RM 1AAThis project is part of a series of trials to evaluate the efficacy of existing vaccines against a particularly virulent strain of Marek's disease which presented in the early 1990's.

  • Marek's disease vaccine trials in commercial birds

    DAV 158AAThis trial was undertaken to develop effective immunisation strategies for the prevention of Marek's disease using newer vaccines  developed by RMIT Melbourne.

  • Rapid identification and pathotyping of virulent IBDV, NDV and AI isolates

    CSA 24JAThe objectives for this project were the development, evaluation and implementation of molecular diagnostic tests for the rapid identification of infectious bursal disease virus (IBDV), Newcastle disease virus (NDV) and avian influenza virus (AIV).

  • Enhancing mucosal immunity in chickens

    US 72AInfection in chickens caused by microbial pathogens at the intestinal surface can be a challenge for the Australian poultry industry. However, there are a number of novel vaccination strategies which can enhance antibody production and reduce the incidence of infection and ultimately improve flock health and performance. The series of experiments in this study seek to evaluate these techniques and determine the most effective method for improving chickens’ antibody production levels. These include delivery of mammalian substances to embryos that are known to stimulate an immune response. In particular, the delivery of dietary supplements Vitamin E and the cytokine interleukin-6 (IL-6) were assessed.

  • National Food Safety Risk Profile of Eggs and Egg Products

    This report set out to identify the following; hazards that enter any point of the food chain for eggs and egg products, potential management strategies for the identified high risk hazards, and product/pathogen combinations in which further risk analysis might be required by risk managers.

  • Infectious Bursal Disease Virus

    CSK 3AJAThe project was initiated in response to reports in 1995 that a more severe strain of IBDV was presenting in Victoria and NSW. The study aims to characterise these strains, to compare  local IBDV strains with those of other countries, and to determine whether current vaccines provide protection against the recently identified aggressive strains.

  • Use of cytokines to enhance vaccine efficacy in poultry

    CSA 26JAThis report outlines the analysis of the immune response during Marek's disease virus infection and the development of reagents used, and assessed, as potential cytokine therapeutics and vaccine adjuvants.

  • Control of Intestinal Spirochaete Infections in Chickens

    UMU 23JInfection of layer and broiler breeders with Avian Intestinal Spirochaetosis (AIS) has emerged as a widespread constraint to optimal production in both the egg and chicken meat industries in Australia. The micro-organisms involved are difficult to isolate and characterise, therefore diagnosis of AIS is often difficult. There is also a lack of information about how to control these infections.
