“…P. multocida includes capsulated and noncapsulated types, with the former being more virulent than the latter (Boyce and Adler, 2000;Chung et al, 2001). P. multocida can be differentiated serologically by capsular antigens into serogroups A, B, D, E, and F (Rimler and Rhoades, 1987), and also by somatic antigens into somatic serotypes 1∼16 (Borgden et al, 1978). Among the five capsular serogroups, B and E cause hemorrhagic septicemia in cattle and wild ruminants (De Alwis, 1992), and serogroup D causes atrophic rhinitis in pigs (Quinn et al, 1994).…”

Fowl cholera is a contagious acute and chronic disease caused by Pasteurella multocida in both domesticated and wild birds. Acute fowl cholera in both chickens and wild birds has recently been documented in Korea, but the chronic form has not been reported in Korea until now. This study describes the first outbreak of chronic fowl cholera in 13-week-old Arbor Acre broiler breeder chickens submitted to the College of Veterinary Medicine, Kyungpook National University in April 2006. The clinical signs of the affected flock of 9,621 chickens were lameness caused by swollen hock joints, diarrhea, ruffled feathers, and an average weekly mortality of 1.0%. At necropsy, purulent or caseous exudates were found in the hock and wing joints, humerus, and eyes, and severe pneumonia and pericarditis were discovered. Eleven bacterial isolates obtained from the liver, joint, infraorbital sinus and sternal bursa of the submitted chickens were all identified as Pasteurella multocida based on their physiological and biochemical characteristics. Five isolates were examined for antimicrobial susceptibility against 21 different antimicrobial agents including ampicillin. All were resistant to kanamycin, neomycin, and streptomycin, and some were resistant to gentamicin. The tested isolates were all susceptible to the other 17 antimicrobial agents. All 11 isolates were capsular serogroup A based on multiplex polymerase chain reaction. In addition, two of five isolates used in the antimicrobial susceptibility test were identified as somatic serotype 1 by an agar gel diffusion precipitin test, while the others were non-typable.

“…Other serotypes of capsular serogroup A have been little studied and relatively little information is available on their role in disease. Strains representing serotypes 1, 3, 4, 5 and 9 were found to be virulent for 1-week-old turkey poults (Rimler, 1987), while a strain of serotype 16 was not virulent for 10-week-old turkeys (Brogden et al, 1978), based on mortality resulting from experimental exposure.…”

Strains of Pasteurella multocida, capsular serogroup A and somatic serotype 14, (A: 14) isolated from turkeys which had succumbed to fowl cholera were examined for virulence and infectivity. Groups of 2-week-old poults were injected intramuscularly with one of three strains. Slight to moderate virulence, based on mortality, was noted. Poults that survived exposure were frequently affected with exudative airsacculitis. Intramuscular, intra-air sac and intranasal exposure of 6-week-old poults with the most virulent strain, as determined in the first experiment, caused the death of one of five intramuscularly-exposed poults. No other clinical evidence was observed. At post mortem examination, marked exudative airsacculitis occurred in all intra-air sac exposed poults, both in inoculated and other air sacs. Pneumonia was also observed in these poults but only affected lungs adjacent to inoculated air sacs. Some poults became carriers of P. multocida.

“…However, it has also been shown that encapsulated isolates from infected birds may be of low virulence (Brogden et al, 1978;Matsumoto & Strain, 1993) and that acapsular forms may be of relatively high virulence (Matsumoto & Strain, 1993), indicating that the presence of a capsule is not the only criterion of virulence. Since Carter & Annau in 1953, hyaluronic acid has been recognized as an major capsule component in some strains of P. multocida.…”
