A highly antigenic fragment within the zoonotic Cryptosporidium parvum Gp900 glycoprotein (Domain 3) is absent in human restricted Cryptosporidium species.

We identified a fragment (Domain 3-D3) of the immunodominant sporozoite surface glycoprotein of the zoonotic parasite Cryptosporidium gp900, which is absent C. hominis and C. parvum anthroponosum.

Variation in the Antimicrobial Susceptibility of Actinobacillus pleuropneumoniae Isolates in a Pig, Within a Batch of Pigs, and Among Batches of Pigs from One Farm.

Antimicrobial resistance in bacterial porcine respiratory pathogens has been shown to exist in many countries. However, little is known about the variability in antimicrobial susceptibility within a population of a single bacterial respiratory pathogen on a pig farm. This study examined the antimicrobial susceptibility of Actinobacillus pleuropneumoniae using multiple isolates within a pig and across the pigs in three different slaughter batches.

Use of a proposed antimicrobial susceptibility testing method for Haemophilus parasuis.

The aim of this study was to examine the antimicrobial susceptibility of 97 Haemophilus parasuis cultured from Australian pigs. As there is no existing standard antimicrobial susceptibility technique available for H. parasuis, methods utilising the supplemented media, BA/SN for disc diffusion and test medium broth (TMB) for a microdilution technique, were initially evaluated with the reference strains recommended by the Clinical and Laboratory Standards Institute.

Antimicrobial resistance in bacteria associated with porcine respiratory disease in Australia.

The porcine respiratory disease complex greatly affects the health and production of pigs. While antimicrobial agents are used to treat the respiratory infections caused by bacterial pathogens, there is no current information on antimicrobial resistance in Australian pig respiratory bacterial isolates. The aim of this study was to determine the antimicrobial resistance profiles, by determining the minimum inhibitory concentration of nine antimicrobial agents for 71 Actinobacillus pleuropneumoniae, 51 Pasteurella multocida and 18 Bordetella bronchiseptica cultured from Australian pigs.
