Physiological, serological, morphological, and cultural differences were observed among 30 Pasteurella multocida cultures of human origin. The usual variations in the fermentation of glycerol, lactose, sorbitol, trehalose, and xylose were observed. Unlike most P. multocida, two cultures did not produce indol. Six serotypes were found. In addition to the widely recognized iridescent, blue, and w...

Avian pasteurellosis caused by Pasteurella multocida was reported among 180 species of wild birds but not reported so far in emu birds. Several emu birds were reported to have died over a period of one week in an organized emu farm. Necropsy findings revealed typical haemorrhagic lesions and characteristic bipolar organism, suggestive of avian pasteurellousis. Two Pasteurella multocida isolates...

Pharyngeal swabs were collected from 298 lesser snow geese (Chen caerulescens caerulescens) at Banks Island (Northwest Territories. Canada) in the summer of 1994. Pasteurella multocida serotype 1 was isolated from an adult male bird and P. multocida serotype 3 was isolated from an adult female goose. Pathogenicity of the serotype 1 isolate was confirmed by inoculation in Pekin ducks (Anas platy...

Clinafloxacin is a broad-spectrum fluoroquinolone that was originally developed and subsequently abandoned in the late 1990s as a human health antibiotic for respiratory diseases. The purpose of this study was to investigate the activity of clinafloxacin as a possible treatment for respiratory disease in cattle and pigs. Minimum inhibitory concentration (MIC) values were determined using Clinic...

Different strategies have been developed to produce vaccines against Pasteurella multocida. The approach described herein involves overexpression on the bacterial cell surface of Fur-regulated IROMPs (iron-regulated outer-membrane proteins). Accordingly, the ability of fur mutants to promote heterologous protection was examined in a Swiss mouse animal model. Twofur mutants derived from P. multo...

Normal ICR mice were infected intravenously, intraperitoneally, or aerogenically with Pasteurella multocida strains isolated from a turkey (S68), calf (V90), or rabbit (J20) lung. Both the turkey and calf isolates were highly virulent for mice and multiplied logarithmically in the lungs, liver, and spleen, resulting in death of the animals in 18 to 36 h. The rabbit strain was avirulent for mice...

Pasteurella multocida is primarily an opportunistic infection, most commonly of skin and soft tissue following animal bites particularly in the elderly and immunocompromised. While invasive disease with P. multocida has been documented in patients at high risk, such as those with organ transplants, malignancy, and cirrhosis, infections other than cellulitis associated with this pathogen are exc...

A 5-yr retrospective study (November 2006-December 2011) was conducted to determine the isolation frequency of Pasteurella multocida and Gallibacterium anatis and their antibiograms from chickens submitted to the Mississippi Poultry Research and Diagnostic Laboratory. The number of isolations of G. anatis increased over the last 5 yr in broiler and broiler breeder type chickens. For P. multocid...

Pasteurella multocida is associated with hemorrhagic septicaemia in cattle and buffaloes, pneumonic pasteurellosis in sheep and goats, fowl cholera in poultry, atrophic rhinitis in pigs and snuffles in rabbits. Haemorrhagic septicaemia is caused by Pasteurella multocida type B:2, B:2,5 and B:5 in Asian countries and type E:2 in African countries. Pasteurella multocida have five types of capsula...

Haemorrhagic septicemia (HS) is a contagious disease in cattle with high morbidity and mortality rates. HS vaccine in Thailand is an oil-adjuvant formulation, and is difficult to administer. The present study aimed to formulate and evaluate the protection in dairy calves conferred by immunization with an in-house intranasal HS vaccine. The intranasal vaccine was formulated in a total volume of ...
