Pasteurellaceae: Biology, Genomics and Molecular Aspects.

Pasteurellosis is suspected to be the cause of recurrent mass mortality of Saiga antelopes.Enzootic pneumonia and atrophic rhinitis of pigs.Fowl cholera ( chicken and other domestic poultry and cage birds).Enzootic pneumonia of sheep (and goats, with frequent intervention of M.The pathologic condition commonly arises where the causative organism becomes established by secondary infection, following a primary bacterial or viral infection, which may occur after stress, e.g. haemolytica serovar A1 is known as the most common cause of the disease. Shipping fever in cattle and sheep ('shipping fever' may also be caused by Mannheimia haemolytica, in the absence of P.multocida, alone or associated with other pathogens: These diseases are considered caused by P. Environmental conditions (transportation, housing deficiency, and bad weather) also play a role. It often acts with other infectious agents, such as Chlamydia and Mycoplasma species and viruses. multocida causes numerous pathological conditions in domestic animals. However, it is most important to treat the wound. Either tetracycline or chloramphenicol provides an alternative in beta-lactam-intolerant patients. Pasteurellosis is usually treated with high-dose penicillin if severe. Treatment Īs the infection is usually transmitted into humans through animal bites, antibiotics usually treat the infection, but medical attention should be sought if the wound is severely swelling. Other locations are possible, such as septic arthritis, meningitis, and acute endocarditis, but are very rare.ĭiagnosis is made with isolation of Pasteurella multocida in a normally sterile site (blood, pus, or cerebrospinal fluid). Zoonosis, pasteurellosis can be transmitted to humans through cats.It usually presents as bilateral consolidating pneumonia, sometimes very severe. Pneumonia disease is also rare and appears in patients with some chronic pulmonary pathology.

Sepsis is very rare, but can be as fulminant as septicaemic plague, with high fever, rigors, and vomiting, followed by shock and coagulopathy.Complications are possible, in the form of septic arthritis, osteitis, or evolution to chronicity. Fever, moderate or very high, can be seen, along with vomiting, headache, and diarrhea. Inflammatory signs are very rapid to develop in 1 or 2 hours, edema, severe pain, and serosanguineous exudate appear. Skin/ subcutaneous tissue disease is a septic phlegmon that develops classically in the hand and forearm after a cat bite.However, for the rare diseases, other methods of specific active surveillance (such as for example sentinel herds) remain important to complete passive surveillance. Passive surveillance stimulated by awareness-raising meetings appears to be better adapted to Chads conditions and less expensive for the surveillance of existing diseases. Finally approximately 83% of the herd visits realised by the active surveillance stations showed negative results (no suspicion identified). Nevertheless, a considerable number of suspicions is recorded during awareness-raising meetings. However, suspicions recorded following farmer calls are significantly more important than suspicions carried out during herd visits or meetings. The results showed that, irrespective of surveillance type, all diseases under surveillance, except the rare diseases (Rinderpest and Rift Valley Fever) were reported by the surveillance agents. The suspicions recorded by the stations were consigned to a suspicion form specific to each disease, indicating whether a call from the farmer, a visit to the herd or a awareness-raising meeting was the source. The passive surveillance stations held each month four farmer awareness-raising meetings.

The active surveillance stations carried out four herd visits monthly to look for the diseases under surveillance and organised four farmers awareness-raising meetings to stimulate them to make disease notifications. Nine diseases of various vaccination and expected prevalence status were monitored. It included 106 surveillance stations of the animal disease epidemiological surveillance network in Chad distributed randomly into 52 stations of active surveillance and 54 stations of passive surveillance. A comparative study between passive and active surveillance based on herd visits (villages) was conducted over a period of 24 months.
