The leukotoxin of Pasteurella (Mannheimia) haemolytica is believed to play a significant role in pathogenesis, causing cell lysis and apoptosis that lead to the lung pathology characteristic of bovine shipping fever. Using a system for Cre-lox recombination, a nonpolar mutation within the lktC transacylase gene of the leukotoxin operon was created. The lktC locus was insertionally inactivated u...

In an unpublished interview conducted by Virginia Smeyers in December 1979, Bryher (born Annie Winifred Ellerman in 1894) repeated: “film was not my métier,” retrospectively attributing her excitement about film and filmmaking to H.D.

Year in and year out, diseases of the respiratory system are a major cause of illness and death in cattle from 6 weeks to two years of age. Sadly, this is as true today as it was 30 years ago despite development of new and improved vaccines, new broad spectrum antibiotics, and increased fundamental knowledge as to the cause of disease. WHY? I don‟t have the answer and I doubt if anyone does. As...

We have determined the 1.35- and 1.45-A structures, respectively, of closed and open iron-loaded forms of Mannheimia haemolytica ferric ion-binding protein A. M. haemolytica is the causative agent in the economically important and fatal disease of cattle termed shipping fever. The periplasmic iron-binding protein of this gram-negative bacterium, which has homologous counterparts in many other p...

this study was done for identification of bacterial agents in calf pneumonia and determination of their antimicrobial susceptibility. bronchoalveolar lavage was done on fourteen pneumonic and seven normal holstein calves between 1-3 month old. in bacteriological examination on the fluid of bronchoalveolar lavage, mycoplasma spp. were isolated from 4 (28.6%) pneumonic calves and 1 (14.3%) health...

Respiratory tract infections with viruses and Pasteurella spp. were determined sequentially among 26 cattle that died during two severe epizootics of shipping fever pneumonia. Nasal swab and serum samples were collected prior to onset of the epizootics, during disease progression, and after death, when necropsies were performed and lung samples were collected. Eighteen normal control cattle als...
