Serological and biochemical characteristics of Pasteurella multocida from free-flying birds and poultry.

چکیده
Biochemical and serological studies were conducted on 73 Pasteurella multocida isolants associated with fowl cholera, 13 from waterfowl, 19 from free-flying birds other than waterfowl, 18 from chickens, 5 from turkeys, and 18 from White Pekin ducks. Three serotypes (1, 3, and 7) were associated with waterfowl, four (1, 3, 6, and 8) with free-flying birds, three (1, 3, and 4) with chickens, one (3) with turkeys, and one (7) with domestic ducks. Fermentation reactions were typical with 18 carbohydrates except that one (sorbitol) occasionally changed from an acid to alkaline reaction after 7 days. The results of these tests on isolants from New York State indicated a relationship among the epornitics of fowl cholera in White Pekin ducks and herring gulls, and a relationship among some of the epornitics in chickens, turkeys, and a pheasant.

Molecular characterization of Pasteurella multocida isolates obtained from poultry, ruminant, cats and dogs using RAPD and REP-PCR analysis
In the present study, Randomly Amplified Polymorphic DNA (RAPD) and Repetitive Extragenic Palindromic sequence-based Polymerase Chain Reaction (REP-PCR) were used to characterize 131 isolates of Pasteurella multocida, originating from different healthy and diseased animal species obtained from several geographical regions of Iran. The RAPD and REP-PCR generated amplified products in the range ...
متن کاملCharacteristics of Pasteurella multocida isolated from humans, swine and poultry in Thailand.
Pasteurella multocida is a pathogen of animals and humans. Most of the patients have been associated with animals but many cases had not contacted them. The failure to diagnose P. multocida infections is mostly due to misidentification on gram stained smears and inadequate laboratory identification techniques. In order to compile detailed characteristics of the organism we studied the physical ...

Pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. A polymerase chain reaction (PCR) assay was developed using primers derived from conserved part of 16S-23S rRNA gene. The PCR amplified a fragment size of 0.7 kb using DNA from nine avian P. multocida isolates...
