Pasteurella multocida was first discovered by Perroncito in 1878 and named after Louis Pasteur who first isolated and described this Gram-negative bacterium as the cause of fowl disease in 1880. Subsequently, P. multocida was also found to cause atrophic rhinitis in pigs, haemorrhagic septicaemia in cattle and respiratory diseases in many other animals. Among other factors such as lipopolysaccharide, outer membrane proteins and its capsule, the protein toxin (PMT) of P. multocida is an important virulence factor that determines the immunological response of the host's immune system. However, the exact molecular mechanisms taking place in cells of the innate and adaptive immune system are largely unknown for any of these virulence factors. Due to the obvious function of PMT on cells of the porcine skeletal system where it causes bone destruction, PMT was regarded as an osteolytic protein toxin. However, it remained unclear what the actual benefit for the bacteria would be. Recently, more attention was drawn to the osteoimmunological effects of PMT and the interplay between bone and immune cells. This review summarises the knowledge of effects of P. multocida virulence factors on the host's immune system.

Pasteurella multocida is a well-recognized zoonotic agent following dog or cat bites or scratches. Nevertheless, prosthetic joint infection caused by P. multocida are rarely reported.
Pasteurella multocida, a Gram-negative facultative anaerobic coccobacillus, is a common oral flora of dogs and cats. P. multocida often causes infection in humans after animal bites and scratches, and...
Respiratory illness is traditionally regarded as the disease of the growing pig, and has historically mainly been associated to bacterial infections with focus on Mycoplasma hyopneumoniae and Actinoba...
OBJECTIVE To develop 2 rapid loop-mediated isothermal amplification (LAMP) assays for detection of Pasteurella multocida DNA (Pm-LAMP assay) and P multocida DNA from strains associated with hemorrhagi...
A microtiter plate-based screening assay capable of determining the activity and regioselectivity of sialyltransferases was developed. This assay was used to screen two single-site saturation librarie...
The chronic immune thrombopenia is an autoimmune disease caused by B cells. These cells produce anti platelets and megakaryocytes antibodies. Some B cells, named regulatory B cells, are kn...
This study investigates the use of the patients own immune cells to treat prostate cancer. Cells are taken from the patient and grown in the laboratory to become specialized immune cells c...
The etiology of infertility in the majority of patients with poor response to ovarian stimulation remains unknown. This study will investigate the role of immune cells (T cells, B cells, ...
The purpose of this study is to learn more about some of the immune cells in the blood (CD4 cells, for example) of healthy children in order to better understand the differences in the blo...

Any of several bacterial diseases, usually caused by PASTEURELLA MULTOCIDA, marked by the presence of hemorrhagic areas in the subcutaneous tissues, serous membranes, muscles, lymph glands, and throughout the internal organs. The diseases primarily affect animals and rarely humans.
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria normally found in the flora of the mouth and respiratory tract of animals and birds. It causes shipping fever (see PASTEURELLOSIS, PNEUMONIC); HEMORRHAGIC BACTEREMIA; and intestinal disease in animals. In humans, disease usually arises from a wound infection following a bite or scratch from domesticated animals.
A chronic, clinically mild, infectious pneumonia of PIGS caused by MYCOPLASMA HYOPNEUMONIAE. Ninety percent of swine herds worldwide are infected with this economically costly disease that primarily affects animals aged two to six months old. The disease can be associated with porcine respiratory disease complex. PASTEURELLA MULTOCIDA is often found as a secondary infection.
Bovine respiratory disease found in animals that have been shipped or exposed to CATTLE recently transported. The major agent responsible for the disease is MANNHEIMIA HAEMOLYTICA and less commonly, PASTEURELLA MULTOCIDA or HAEMOPHILUS SOMNUS. All three agents are normal inhabitants of the bovine nasal pharyngeal mucosa but not the LUNG. They are considered opportunistic pathogens following STRESS, PHYSIOLOGICAL and/or a viral infection. The resulting bacterial fibrinous BRONCHOPNEUMONIA is often fatal.
Chronic endemic respiratory disease of dairy calves and an important component of bovine respiratory disease complex. It primarily affects calves up to six months of age and the etiology is multifactorial. Stress plus a primary viral infection is followed by a secondary bacterial infection. The latter is most commonly associated with PASTEURELLA MULTOCIDA producing a purulent BRONCHOPNEUMONIA. Sometimes present are MANNHEIMIA HAEMOLYTICA; HAEMOPHILUS SOMNUS and mycoplasma species.
The term allergy is used to describe a response, within the body, to a substance, which is not necessarily harmful in itself, but results in an immune response and a reaction that causes symptoms and disease in a predisposed person, which in turn can cau...
Sepsis, septicaemia and blood poisoning
Septicaemia (another name for blood poisoning) refers to a bacterial infection of the blood, whereas sepsis can also be caused by viral or fungal infections. Sepsis is not just limited to the blood and can affect the whole body, including the organ...
