Genetic organisation of the capsule transport gene region from Haemophilus paragallinarum.

Reclassification of Pasteurella gallinarum, [Haemophilus] paragallinarum, Pasteurella avium and Pasteurella volantium as Avibacterium gallinarum gen. nov., comb. nov., Avibacterium paragallinarum comb. nov., Avibacterium avium comb. nov. and Avibacterium volantium comb. nov.

This paper describes a phenotypic and genotypic investigation of the taxonomy of [Haemophilus] paragallinarum, Pasteurella gallinarum, Pasteurella avium and Pasteurella volantium, a major subcluster within the avian 16S rRNA cluster 18 of the family Pasteurellaceae. An extended phenotypic characterization was performed of the type strain of [Haemophilus] paragallinarum, which is NAD-dependent, ...

Genetic analysis of a plasmid encoding haemocin production in Haemophilus paragallinarum.

The full sequence of plasmid p250, isolated from Haemophilus paragallinarum strain HP250, has been obtained. The plasmid contains seven ORFs: a putative integrase, a putative replication protein (repB) and five ORFs similar to those from the haemocin (bacteriocin) hmcDCBAI operon from Haemophilus influenzae. Of 19 other non-plasmid-containing H. paragallinarum strains screened (11 serovar refer...

The testing and modification of a commercially available transport medium for the transportation of pure cultures of Haemophilus paragallinarum for serotyping.

Haemophilus paragallinarum, the causative agent of infectious coryza in poultry, is an extremely fastidious organism requiring specific growth conditions for isolation. For complete control of the disease in regions where more that one of the serovars of the different serogroups occurs, it is essential that the bacterium causing the problem be isolated and serotyped. This work describes the mod...

جداسازی، شناسایی و تعیین حساسیت آنتی بیوتیکی Haemophilus paragallinarum جدا شده از گله های تخمگذار تجاری مبتلا به کوریزای عفونی

Confirmation that PCR can be used to identify NAD-dependent and NAD-independent Haemophilus paragallinarum isolates.

Seventy five bacteria tentatively identified as Haemophilus paragallinarum (the causative agent of infectious coryza), eight identified as Ornithobacterium rhinotracheale and 13 identified as NAD-independent Pasteurella species were isolated from chickens with respiratory infection in various provinces in South Africa. The isolates were characterized by conventional biochemical and serological ...
