The serum antibody responses of cattle with respiratory coronavirus infections during the pathogenesis of shipping fever pneumonia were analyzed with different bovine coronavirus antigens, including those from a wild-type respiratory bovine coronavirus (RBCV) strain (97TXSF-Lu 15-2) directly isolated from lung tissue from a fatally infected bovine, a wild-type enteropathogenic bovine coronaviru...

lnfectious Bovine Rhinotracheitis (IBR; bovine herpesvirus 1 (BHV-1); Rednose) is one of several cattle respiratory viruses that plays a large role in the shipping fever complex. One of the major problems with IBR is that like other herpesviruses, once animals are infected they carry the virus for life. Investigations in our laboratory have been aimed at understanding how the IBR virus gets int...

Pasteurella multocida serotype A:3 is a Gram-negative bacterial pathogen, one of the causative agents of shipping fever of cattle. In this study, outer membrane protein H (ompH) and Pasteurella lipoprotein E (plpE) genes were cloned and plpEC-ompH fusion was constructed and expressed in Escherichia coli. Recombinant PlpE, OmpH and PlpEC-OmpH fusion proteins were purified and formulated with oil...

Hemorrhagic septicemia is an economically important bacterial disease of cattle and buffaloes [6]. The disease remains a significant obstacle to sustainable livestock production in most parts of tropical Asia and Africa. It is caused by Pasteurella multocida a natural inhabitant of the mucosal surfaces of upper part of the respiratory tract of ruminants, and under predisposing environmental or ...

Virus Diseases Many of the parasitic, nutritional and, to some extent, infectious diseases of cattle have been known for years and are readily handled by proper use of antibiotics and addition of minerals and vitamins to the ration. Recent studies indicate that 65 percent of the feedlots sampled in one state were infected with para influenza 3 virus ( the virus involved in shipping fever } . An...

An outbreak of Haemorrhagic septicaemia among dairy cattle was investigated. Clinical signs and necropsy findings were described. Morphological, cultural and biochemical characteristics obtained from staining and culturing of 18 blood samples, collected from morbid cows, demonstrated the presence of Pasteurella multocida. INTRODUCTION: Septicaemic pasteurellosis (Haemorrhagic septicaemia) is an...

  This study was carried out at the Razi Institute during 2005-2006 with inspecting 12168 lung tissue of slaughtered sheep and goats at the Ziaran Abattoir. Pneumonia were diagnosed in 282 cases and the affected lung tissue was collected and transferred to the Bacteriology and Pathology Departments for isolating of Pasteurella spp. and interpretation of histopathologic lesions. Pasteurella mult...
