“…P. maltocida differ from Mannheimia hemolytica in that it was non hemolytic on blood agar medium didn't grow on Macconcky agar, and indol positive results agreed with Karaivnov (1984); Collee et al, (1996). Experimental infection of chickens with both of Mannheimia hemolytica and P. multocida caused morbidity and mortality reached to 80% in both cases this resembling the results recorded by Curtis and Allerhead (1981); Lin et al,(2001); Bojesen et al, (2004a).…”

Avian Mannheimia hemolytica and Pasteurella multocida were investigated in different poultry farms at Beni-Suef governorate. Bacteriological examination of 160 samples which were taken from organs of freshly dead and diseased chickens revealed isolation of 50 (31.25%) isolates of Pasteurella.Spp., 16 (10%) isolates were Mannheimia hemolytica and 34(21.25%) isolates were Pasteurella multocida. Experimental infection was carried out on four weeks old Balady chickens which were inoculated with isolates of Mannheimia hemolytica and Pasteurella multocida separately, mortality rate in both reached to 80%. Samples were taken from dead chickens and examined bacteriolgically and histopathologicaly and Pasteurella. Spp. were reisolated from experimentally infected chickens. Antibiogram study with 10 types of chemotherapeutic agents revealed that both microorganisms were sensitive to ceftiofor, gentamycin and lincomycin + spectinomycin. The gross and microscopic pathologic lesions were variable in type and severity in field and experimentally infected cases. There was general hyperemia which most evident in veins of the abdominal viscera. Petecheal haemorrhages were frequently found and widely distributed. Livers of the most acutely affected birds were swollen and had multiple small focal areas of coagulative necrosis and heterophilic infiltration. Heterophilic infiltration also occurs in lungs and certain other parenchymotous organs.

“…The disease usually occurs in birds in two forms: an acute septicemia with high morbidity and mortality rates, and a chronic localized infection of joints and sinuses (Gilsson et al, 2003). Chronically infected birds are considered to be a major source of transmission and the most likely routes of FC transmission among birds are through direct contact or via contaminated water (Christensen and Bisgaard, 2000;Curtis and Ollerhead, 1981).…”

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.

“…Carriers have also been demonstrated in domestic poultry flocks previously affected by fowl cholera Kasten et al, 1997). Healthy turkeys and chickens have not been considered to be carriers of P. multocida (Curtis & Ollerhead, 1981;Carpenter et al, 1989). However, P. multocida has recently been isolated from healthy flocks of web-footed birds and chickens (Muhairwa et al, 2000), although it is not known how P. multocida was introduced into these flocks.…”

Virulence ofPasteurella multocidasubsp.multocidaisolated from outbreaks of fowl cholera in wild birds for domestic poultry and game birds

et al. 2001

Chickens, turkeys, partridges and pheasants were experimentally infected with Pasteurella multocida subsp. multocida to investigate whether outbreaks of fowl cholera in avifauna might represent a risk for organic, backyard and industrial poultry production. Birds were infected intra-tracheally with a strain of P. multocida subsp. multocida (40605-1) isolated from outbreaks of fowl cholera in wild birds in Denmark. P. multocida subsp. multocida strain P-1059 was included as a reference strain. The outbreak strain was highly virulent for turkeys, partridges and pheasants, while chickens were more resistant. The present findings underline the importance of wild birds as a reservoir for P. multocida. Intratracheal challenge proved useful for studying the virulence of P. multocida.
