| Se determinó la frecuencia de Mannheimia haemolytica (Mh) y Pasteurella multocida (Pm) obtenidas de exudado nasal de becerras afectadas por enfermedad respiratoria, en un complejo lechero del estado de Hidalgo, México, evaluadas durante 5 meses en un estudio descriptivo transversal. El aislamiento e identificación se hizo mediante procedimientos selectivos y pruebas bioquímicas. Se evaluó la asociación de algunas variables con el aislamiento de Mh y Pm, mediante Ji cuadrada o Fisher, el cálculo de la razón de momios y el análisis de regresión logística. De 239 becerras menores de un año, estudiadas, en 84 (35.14%) se aisló Mh o Pm, de ellas, 67 (28.03%) con Mh y 17 (7.11%) con Pm; en 8 becerras (3.10%) se aislaron ambos microorganismos. Se evaluaron... |

| Pasteurella multocida is an important veterinary pathogen that causes a range of animal diseases, including fowl cholera, hemorrhagic septicemia in cattle and atrophic rhinitis in swine. P. multocida is generally recognized as a secondary invader contributing substantially to respiratory diseases in pigs by aggravation of lung lesions. Five capsule serogroups are routinely identified in P. multocida (A, B, D, E, and F) and each is generally associated with, but not completely restricted, to a specific host. A total of 16 isolates of Pasteurella multocida capsular genotype A and two isolates capsular genotype D were characterized for their susceptibilities to 10 antibiotics and the presence of four genes for virulence factors associated to adherence. The... |

| ABSTRACT: In this work, we describe an unusual case of fibrinous pleuropneumonia caused by Pasteurella multocida associated with generalized lymphadenomegaly in a bovine. The animal had a one-month history of generalized superficial lymphadenomegaly that progressed to anorexia and submandibular oedema, resulting in spontaneous death. At necropsy, the parenchyma of the lymph nodes and multiple organs was obliterated by a dense proliferation of round neoplastic cells (lymphoma). Additionally, the neoplasm presented multifocal areas of haemorrhage and necrosis, characteristic of lymphoma. The parietal and visceral pleura and parietal pericardium were enlarged and covered diffusely with large amounts of a yellowish fibrillary material. The lungs were mildly... |
