Fifty-six E. coli, 37 P. multocida and 8 M. haemolytica were isolated from 157 nasal swabs taken from calves in 52 dairy herds. The antibiotic susceptibility of the organisms was determined by measurement of the minimal inhibitory concentrations. Of the 56 E. coli isolates, 55.3% exhibited...

The epidemiology, prevalence, aetiology, risk factors, diagnosis, prevention and control of bovine flu in Germany are discussed.

Hemorrhagic septicemia, an peracute/acute disease caused by Pasteurella multocida capsular type B, led to considerable losses (19 milking cows and juvenile cattle) on a dairy farm in Lower Saxony. The affected farm used two milking robots, which accumulated various milking data. Collected data were ...

Bovine Respiratory Disease (BRD) is one of the most important reasons for disease and even loss in both, cattle rearing and fattening. In Switzerland, calves from dairy farms are commingled and then housed on fattening farms approximately at the age of 2 to 4 weeks which makes a prophylactic...

Livestock farming is always associated with an exposure, i.e. with a contact to various infectious agents. As part of the defense against these pathogens certain processes take place, which result at best in an elimination of the pathogen. For this purpose the body has a repertoire of regulatory...

This paper highlights the results of a study aimed at determining the effects of crowding in dairy calves on the occurrence of Bovine Respiratory Diseases. Focused of the study looks at the host immunity, stress factors, and Pasteurella multocida and Mannheimia haemolytica in the pathogenesis of...

This article discusses the principles of vaccination against infectious diseases in cattle. Focus is given on vaccine types used, assessment of antibody formation and immune response, time of vaccination, vaccine delivery systems, common infectious diseases in cattle (bovine herpesvirus-1, bovine...

Hemorrhagic septicaemia, an acute disease caused by P. multocida capsular type B which is rarely detected in Europe, caused considerable losses in fallow deer, cattle and pigs within a region along the border of the federal states Brandenburg and Saxony-Anhalt in the summer of 2010. Clinical...

The Bovine Respiratory Disease Complex (BRDC) in calves causes substantial economical losses due to treatment costs, loss of animals, growth retardation and diminished carcass quality. BRDC is a multifactorial disease, which is elicited by interactions between the host and a number of risk factors, ...
