Hydroxamate siderophores of Histoplasma capsulatum.
The zoopathogenic fungus Histoplasma capsulatum, like other eukaryotic aerobic microorganisms, requires iron for growth. Under conditions of low iron availability, the fungus secretes hydroxamates that function as siderophores (iron chelators). The experiments to be reported were designed to gather further information on the hydroxamate siderophores of H. capsulatum. The fungus was grown in a s...
متن کاملEffects of growth conditions on biofilm formation by Actinobacillus pleuropneumoniae
Biofilm formation is an important virulence trait of many bacterial pathogens. It has been reported in the literature that only two of the reference strains of the swine pathogen Actinobacillus pleuropneumoniae, representing serotypes 5b and 11, were able to form biofilm in vitro. In this study, we compared biofilm formation by the serotype 1 reference strain S4074 of A. pleuropneumoniae grown ...
متن کاملCatecholamines Promote Actinobacillus pleuropneumoniae Growth by Regulating Iron Metabolism
Catecholamines are host stress hormones that can induce the growth of many bacteria by facilitating iron utilization and/or regulate the expression of virulence genes through specific hormone receptors. Whether these two responsive pathways are interconnected is unknown. In our previous study, it was found that catecholamines can regulate the expression of a great number of genes of Actinobacil...
متن کاملActinobacillus pleuropneumoniae disease and serology
Actinobacillus pleuropneumoniae is a primary bacterial pathogen causing swine respiratory disease and has been described in most major swine-producing regions of the world. Preliminary diagnosis of A. pleuropneumoniae is based on clinical signs and gross pneumonic lesions. Isolating and identifying the causative bacteria confirms the diagnosis. Twelve serotypes of A. pleuropneumoniae and a numb...
متن کاملSerological characterisation of Actinobacillus pleuropneumoniae
In the most recent study on the serological characterisation of Australian isolates of A pleuropneumoniae, a large percentage of isolates either gave cross-reactions with serovars 3 and 6 (47/256 isolates) or no reaction at all (91/256 isolates).11 This study was performed using slide agglutination and GD, techniques which had performed effectively in the past.5 The high incidence of isolates t...
