“…On premises O, the cat was trapped 5 months after the fowl cholera outbreak in the turkeys but may have been carrying P. multocida for some time. Cats are recognized carriers of P. multocida, with prevalence rates of up to 92% being recorded (3,11,20,25). However, their means of transmitting the organism to poultry is uncertain, as they are not normally though to attack turkeys (11).…”

“…had led to many species being postulated as reservoirs of infection for poultry (10, 11,20,25). Live attenuated strains of P. multocida, such as Clemson University and M9, are used to prevent fowl cholera in turkeys but may produce the disease in a proportion of birds (4,28).…”

Restriction endonuclease analysis (REA) of whole-cell DNA was used to determine possible sources of Pasteurella multocida for each outbreak of fowl cholera occurring in turkey flocks in eight commercial poultry companies in California from October 1988 to September 1989. Over this period, 179 isolates of P. multocida were obtained from dead turkeys in 80 meat and breeder flocks on 43 premises. P. multocida was isolated from wildlife on five premises. Isolates were characterized by subspecies, serotype, presence of plasmid DNA, and REA type. In 52 (65%) flocks, all isolates of P. multocida had the same REA pattern as the M9 live vaccine strain following digestion of DNA with the restriction enzyme SmaI. Field strains of P. multocida were obtained from 27 (34%) flocks, and one flock (1%) yielded both M9 and a field strain of the organism. REA of field strains of P. multocida revealed 17 different SmaI REA types. Based on matching SmaI REA types, potential sources of P. multocida were identified for 15 of the 28 flocks infected with field strains of the organism, and transmission between turkey premises was a possibility in only seven flocks.

“…However, a recent investigation found different clones of P. multocida in each of four outbreaks of fowl cholera on a duck farm over a 2-year period (Muhairwa et al ., 2000), indicating that elimination of P. multocida from infected farms is possible even in duck farms with a low level of biosecurity, as might be expected for a pathogen that is easily inactivated by common disinfectants, sunlight, drying or heat, and that survives for a maximum of 30 days in the environment (Backstrand & Botzler, 1986;Glisson et al ., 2003). P. multocida may have persisted by colonization of the cats that were kept at both affected farms, as they may act as reservoirs of P. multocida that are virulent for poultry (Curtis & Ollerhead, 1982;Snipes et al ., 1988;Korbel et al ., 1992;Van Sambeek et al ., 1995;Glisson et al ., 2003). As the majority of avian, ovine, bovine and porcine respiratory tract infections are caused by different clones of P. multocida (Davies et al ., 2004), it seems unlikely that cats commonly act as a reservoir; transmission of P. multocida by cats and dogs needs to be investigated in more detail, as a recent study by Muhairwa et al (2001) suggested that P. multocida are not commonly exchanged between poultry and carnivores, even when they are kept in close contact.…”

Detailed longitudinal studies of the genetic stability of Pasteurella multocida ssp. multocida, the cause of fowl cholera, have not previously been carried out. Consequently, the aim of the present study was to provide detailed information on the genetic stability and diversity of P. multocida ssp. multocida in poultry flocks over time, enabling new insights into the molecular epidemiology of this important poultry pathogen. Longitudinal investigations of the rate and causes of mortality were carried out on two free-range layer farms (A and B) over a period of 11 months. The total mortality of two flocks, A 1 and A 2 , on farm A were 62 and 91%, respectively, while the total mortality of a single flock B 1 on farm B was 6%. Postmortem examinations were performed on 708 layers from flocks A 1 and A 2 and in 159 from flock B 1 . Fowl cholera was the main cause of mortality on both farms. Pasteurella multocida isolates recovered from layers on both farms were characterized phenotypically and genotypically, and 322 isolates were identified as P. multocida ssp. multocida. The genetic diversity of 99 isolates from farm A and 31 from farm B was characterized by restriction endonuclease analysis and amplified fragment length polymorphism analysis. The isolates on each farm had a unique restriction endonuclease analysis and amplified fragment length polymorphism analysis type, suggesting a

Pasteurella multocida, the etiologic agent of fowl cholera, was isolated from six broiler flocks in Georgia during summer 1988. The flocks ranged in age from 20 to 46 days, represented four companies, and spanned a distance of 50 miles. Increased mortality and lameness were the clinical signs present in all affected flocks. Bacterial isolation and agar gel precipitation for somatic antigen serotyping revealed that three of the cases were caused by serotype 1,3, two by serotype 3,4, and one by serotype 3. To prove the virulence of these organisms, two isolates were selected to challenge 5-week-old broilers. Mortality and lameness resulted from this challenge, and P. multocida was reisolated.
