Mechanism of ToxicityStimulation of several signalling pathways is induced by PMT. Most remarkable is a potent mitogenic effect. Phospholipase C-beta and the small GTPase Rho are activated due to stimulation of heterotrimeric G proteins of the Galpha(q), Galpha(i), and Galpha(12/13) families. (1)
MetabolismFree toxin may be removed by opsonization via the reticuloendothelial system (primarily the liver and kidneys) or it may be degraded through cellular internalization via the lysosomes. Lysosomes are membrane-enclosed organelles that contain an array of digestive enzymes, including several proteases.

Health EffectsPasteurella multocida toxin (PMT) is the major pathogenic deteriment of Pasteurella multocida. Pasteurella multocida can cause a zoonotic infection in humans, which typically is a result of bites or scratches from domestic pets. This causes an inflammatory reaction at the infection site (generally a diffuse localized cellulitis). It can also infect other locales, such as the respiratory tract. In more serious cases, a bacteremia can result, causing an osteomyelitis or endocarditis. The bacteria may also cross the blood-brain barrier and cause a meningitis. (2)
SymptomsPasteurella multocida can cause a zoonotic infection in humans, which causes an inflammatory reaction at the infection site (generally a diffuse localized cellulitis). It can also infect other locales, such as the respiratory tract. In more serious cases, a bacteremia can result, causing an osteomyelitis or endocarditis. The bacteria may also cross the blood-brain barrier and cause a meningitis. (2)
TreatmentThis bacterium can be effectively treated with beta-lactam antibiotics, which inhibit cell wall synthesis. It can also be treated with fluoroquinolones or tetracyclines; fluoroquinolones inhibit bacterial DNA synthesis and tetracyclines interfere with protein synthesis by binding to the bacterial 30S ribosomal subunit. Because P. multocida is most often acquired as a result of a bite (notably dog), infections are frequently polymicrobial and involve anaerobic bacteria. As a result, amoxicillin-clavulanate (a beta-lactamase inhibitor/penicillin combination) is seen as the treatment of choice. (2)

Targets

General Function:
Signal transducer activity
Specific Function:
Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(i) proteins are involved in hormonal regulation of adenylate cyclase: they inhibit the cyclase in response to beta-adrenergic stimuli. The inactive GDP-bound form prevents the association of RGS14 with centrosomes and is required for the translocation of RGS14 from the cytoplasm to the plasma membrane. May play a role in cell division.
