apx toxins in pasteurellaceae species from animals.pasteurellaceae species particularly of porcine origin which are closely related to actinobacillus pleuropneumoniae were analyzed for the presence of analogues to the major a. pleuropneumoniae rtx toxin genes, apxicabd, apxiica and apxiiicabd and for their expression. actinobacillus suis contains both apxicabd(var.suis) and apxiica(var. suis) operons and was shown to produce apxi and apxii toxin. actinobacillus rossii contained the operons apxiica(var.rossii) and apxiiicabd(var.rossii). however, ...200010831858
distribution of rtx toxin genes in strains of [actinobacillus] rossii and [pasteurella] mairii.strains of [actinobacillus] rossii, [pasteurella] mairii and [pasteurella] aerogenes can be isolated from abortion in swine. the rtx toxin pax has previously been found only in those [p.] aerogenes strains isolated from abortion. nothing is known about rtx toxins in field isolates of the other two species. to gain insight into the distribution of selected rtx toxin genes and their association with abortion, pcr screening for the pax, apxii and apxiii operons on 21 [a.] rossii and seven [p.] mair ...200616621343
emended description of porcine [pasteurella] aerogenes, [pasteurella] mairii and [actinobacillus] rossii.the aim of this study was to improve the definition and identification of a group of veterinarily important bacteria referred to as the [pasteurella] aerogenes-[pasteurella] mairii-[actinobacillus] rossii complex. these organisms have mainly been isolated from the reproductive and intestinal tracts of pigs and in most cases have been considered as opportunistic pathogens. a collection of 87 strains were characterized by phenotypic analysis from which 41 strains were selected for 16s rrna gene se ...200515653877
immunological properties of actinobacillus pleuropneumoniae hemolysin i.the 105 kda hemolysin i protein from actinobacillus pleuropneumoniae serotype i type strain 4074 (hlyi) was shown by immunoblot analysis to be the predominant immunogenic protein if convalescent field sera or sera from pigs experimentally infected with a. pleuropneumoniae serotype 1 were used. sds gel- and immunoblot-analysis using total culture, washed cells or culture supernatant showed that hlyi is essentially secreted and is not found attached to the bacteria. proteins in the 105 kda range t ...19911887566
actinobacillus rossii sp. nov., actinobacillus seminis sp. nov., nom. rev., pasteurella bettii sp. nov., pasteurella lymphangitidis sp. nov., pasteurella mairi sp. nov., and pasteurella trehalosi sp. nov.evidence from numerical taxonomic analysis and dna-dna hybridization supports the proposal of new species in the genera actinobacillus and pasteurella. the following new species are proposed: actinobacillus rossii sp. nov., from the vaginas of postparturient sows; actinobacillus seminis sp. nov., nom. rev., associated with epididymitis of sheep; pasteurella bettii sp. nov., associated with human bartholin gland abscess and finger infections; pasteurella lymphangitidis sp. nov. (the blg group), w ...19902223608
