| ABSTRACT Although Pasteurella multocida is a member of the respiratory microbiota, under some circumstances, it is a primary agent of diseases , such as fowl cholera (FC), that cause significant economic losses. Experimental inoculations can be employed to evaluate the pathogenicity of strains, but the results are usually subjective and knowledge on the pathogenesis of this agent is still limited. The objective of this study was to establish a new methodology for classifying the pathogenicity of P. multocida by formulating a standard index. Strains isolated from FC cases and from swine with respiratory problems were selected. One hundred mL of a bacterial culture of each strain, containing 106 CFU, was inoculated in 10 one-day-old broilers. Mortality after... |

| El objetivo del presente estudio fue identificar y caracterizar los tipos capsulares de P. multocida en exudado faríngeo en bovinos destinados a la producción de carne en el estado de Querétaro. Se obtuvieron, mediante hisopo, 227 muestras de exudado faríngeo de animales clínicamente sanos en una planta de sacrificio ubicada en el municipio de Ezequiel Montes, Querétaro. Las muestras se sembraron en agar sangre y se incubaron a 37°C por 24 h en aerobiosis. Las cepas aisladas fueron identificadas mediante características morfológicas, pruebas bioquímicas convencionales y el microsistema comercial API 20NE. La tipificación de los grupos capsulares A y D se realizó por medio de una PCR múltiple para la amplificación de los genes hyaD-hyaC y dcbF,... |

| Respiratory infection is the most serious disease affecting poultry and causing great economic losses to the poultry industry worldwide. In avian host, several microorganisms of the genus Pasteurella (P. multocida, P. gallinarum and P. anatipestifer), Bordetella (B. avium) and Avibacterium paragallinarum) were involved in respiratory diseases complex. Ornithobacterium rhinotracheale is a recently discovered bacterium, of worldwide distribution in commercial poultry, in which it is associated to respiratory diseases and it is also found in wild birds. Airsacculitis and pneumonia are the most common symptoms of infection with O. rhinotracheale. Isolation and identification of pathogenic bacteria associated to respiratory diseases were carried out from a... |

| Pasteurella multocida es parte de la flora comensal del tracto respiratorio superior de cerdos. Usualmente, las cepas de P. multocida del serotipo A se asocian a neumonía en animales de crecimiento y las del serotipo D codifican para una toxina de 145 kDa asociada a la rinitis progresiva. En este trabajo se realizó la caracterización bioquímica y molecular de 30 cepas de P.multocida aisladas a partir de cerdos con clínica respiratoria. Todos los aislamientos presuntivos de P.multocida fueron positivos para los cebadores KMT1SP6 y KMT1T7, amplificando un producto de 460 pb. La presencia del gen tox A solo se detectó en 4 muestras, demostrando la baja frecuencia de cepas toxigénicas y mayor prevalencia de cepas de P.multocida asociadas a procesos neumónicos... |

| O ensaio in vitro objetivou avaliar o efeito do álcool PA e de diferentes concentrações (5%, 10% e 15%) no Agar, do Extrato Alcoólico de Própolis (EAP), de três regiões do Estado de São Paulo, sobre a Pasteurella multocida, obtida a partir de swab nasal de coelhos. Por meio de outro ensaio, analisou-se o comportamento dessas bactérias em lavado tráqueo-brônquico de coelhos, alimentados com rações contendo álcool PA e diferentes concentrações de EAP (0,1%; 0,2% e 0,3%). O álcool só foi efetivo na inibição do desenvolvimento bacteriano in vitro na concentração mais elevada, enquanto o EAP demonstrou efetividade em todas as concentrações. As amostras de própolis das três regiões não diferiram entre si. No lavado tráqueo-brônquico, o número de Unidades... |

| Frequency of Mannheimia haemolytica and Pasteurella multocida in the respiratory tract of lambs in the region of Botucatu, SP, Brazil, was studied. Nasopharingeal and oropharingeal swabs were obtained from 262 animals: 180 from healthy and 82 from animals with respiratory diseases. M. haemolytica was the most prevalent (47%), followed by the association of M. haemolytica and P. multocida (27%), and P. multocida (11%). Animals with respiratory disease presented higher occurrence of P. multocida in the nasopharynx as compared to healthy animals (P<0.05). No significant difference in isolation rate of M. haemolytica, P. multocida, and association of these microorganisms in the oropharynx of healthy and affected animals was observed. |

| Pasteurella multocida belongs to the normal flora of the respiratory and digestive tract of many animals. Animal exposure is a considerable risk factor for Pasteurella infection. P. multocida is the most common cause of local infection after an animal bite but is an unusual cause of meningitis. We present a case of bacterial meningitis by P. multocida in a 37-year-old man who worked in a pig farm and was bitten by a pig. The patient had a defect located in the lamina cribosa and this lesion could be the gateway of the infection, although in this case the infection could also be acquired through the pig bite. The bacteria was identified as P. multocida with the biochemical test API 20E (bioMérieux). In agreement with findings in the literature, the strain... |

| A study was performed to verify the presence of Pasteurella multocida in eight different poultry groups of 90 birds each. Groups I to IV were chickens (I being > 6 weeks of age with a history of respiratory illness, II > 6 weeks of age and free of respiratory illness, III < 6 weeks of age with respiratory illness and IV being < 6 weeks of age and with no respiratory illness. Groups V to VIII had the matching characteristics of Groups I to V but consisted of Japanese Quails. The P. multocida isolation rate from the groups was as follows; Group I 56/90 (62.3%) Group II 18/90 (20.0%), Group III 12/90 (13.3%), Group IV 3/90 (3.33%), Group V 8/90 (8.88%), Group VI 2/90 (2.22%) Group VII 2/90 (2.22%) and Group VIII 1/90 (1.11%).

| ABSTRACT: Swine respiratory diseases such as atrophic rhinitis and bronchopneumonia caused by Pasteurella (P.) multocida cause important economic losses to the modern swine industry. The purpose of this study was to characterize P. multocida strains isolated from swine lungs by RAPD (Randomly Amplified Polymorphic DNA) to demonstrate their genetic diversity. Ninety-four samples of fragments from lungs with pneumonia and sixty one samples without pneumonia were collected in slaughterhouses in Mato Grosso during the period from December 2009 to March 2010. Clinical cases in 2012 and 2013 were also included in this study. Among the lung fragments with macroscopic lesions, without macroscopic lesions and clinical samples, 40.42%, 4.49% and 100% were positive... |
