| epidemiologic studies on infectious coryza outbreaks in northern new south wales, australia, using serotyping, biotyping, and chromosomal dna restriction endonuclease analysis. | the epidemiology of 16 cases of infectious coryza, an upper respiratory tract disease of chickens caused by haemophilus paragallinarum, was investigated in a retrospective study. the cases occurred over a 14-month period on 10 farms in northern new south wales. the available field data indicated that the cases formed six unrelated outbreaks. the 16 isolates of h. paragallinarum were subjected to serotyping by the page and kume schemes and biotyping based on carbohydrate fermentation and antimicr ... | 1990 | 2196042 |
| characterisation of pasteurella multocida isolated from fowl cholera outbreaks on turkey farms. | biochemical profiles, restriction endonuclease analysis (rea) and ribotyping were used to investigate pasteurella multocida isolates from outbreaks of fowl cholera on 7 turkey farms in new south wales. while only a single isolate was available from 5 of the farms, multiple isolates, 4 and 12 respectively, were available from the other 2 farms. the available field evidence suggested that 8 outbreaks had occurred with one farm suffering 2 outbreaks. the isolates obtained were all confirmed as past ... | 1995 | 7544114 |
