Immunity assays on sheep sera using passive mouse protection tests showed that vaccines containing more than 4 strains of Pasteurella multocida did not give a good immunity. The immune response was not enhanced by the use of an oil adjuvant, and high concentrations of bacteria had only a partial positive effect. Attempts to extract selectively the protection-inducing antigen(s) from P. multocid...

The present experiment was conducted to study the effect of ethanolic extract of Egyptian propolis given alone or in combination with inactivated Pasteurella multocida vaccine on rabbits challenged with a virulent strain of Pasteurella multocida. Fifty-six New-Zealand rabbits, 6-8 weeks old and non-vaccinated against pasteurellosis, were randomly divided into eight equal groups. The first group...

BACKGROUND Sheep constitute the second major component of livestock in Ethiopia. However, efficient utilization of this potential resource is hampered by combination of health problems, poor management and feed shortage. Haramaya district is one of the remote settings in Ethiopia where information about the livestock disease is not well documented. Hence this study was conducted to determine th...

Objective: The study aimed to molecular characterization of Pasteurella multocida local strain using Enterobacterial Repetitive Intergenic Consensus (ERIC), 13 virulence genes and the outer membrane protein (OmpH) gene. Also, development of diagnostic markers by multiplex PCR from investigated genes. Methodology: The ERIC-PCR was used for the detection of the finger print of Pasteurella multoci...

Pasteurella spp. are Gram-negative facultative bacteria that cause severe economic and animal losses. Pasteurella-based vaccines the most promising solution for controlling outbreaks. Remarkably, insufficient biomass cultivation (low cell viability productivity) lack of knowledge about process have impacted bulk production vaccines. Bioprocess optimization in shake flask bioreactor is required ...

Bovine respiratory disease caused by Mycoplasma bovis is a major health problem of cattle worldwide. It inflicts considerable financial losses on beef herds and is the most common cause of mortality in dairy cattle. Bacteriological examination of 35 nasal cavity samples from calves younger than three months of age identified Mycoplasma bovis in eight (22.9%) samples. These cattle were followed ...

in order to show the type and severity of gross and histopathologic lesions induce by vaccinal strain (serotype a1) of pateurella mulocida, ten four-week-old spf chickens were inoculated intramuscularly with 75 cfu of ( 0.5 ml of 10-7 dilution) bacterium. all birds died in less than 16 hours. no prominent gross lesions were observed in different organs. in microscopic examination, the most comm...

Pasteurella multocida serotype B:2 is the causative agent of hemorrhagic septicemia in cattle and buffaloes in Asia. It is an acute fatal disease and is considered one of the most economically important diseases in this region of the world. We present here the draft genome sequences of strains 2213 and 3213 of P. multocida.

Pasteurella multocida is a major pathogen of farm animals and has worldwide distribution. Here we report the draft genome sequences of four strains that were isolated from animals in the United Kingdom and the United States and represent pathogenic and commensal presentation of the bacterium.

In this study, 108 P. multocida isolates recovered from various host animals such as cattle, buffalo, swine, poultry (chicken, duck, and emu) and rabbits were screened for carriage of 8 virulence associated genes. The results revealed some unique information on the prevalence of virulence associated genes among Indian isolates. With the exception of toxA gene, all other virulence associated gen...
