Transcriptional analysis to identify the iron uptake systems of Mannheimia haemolytica [PDF]

, 2008
Mannheimia haemolytica und Pasteurella multocida gehören zu den Verursachern der unter Rindern weltweit verbreiteten Enzootischen Bronchopneumonie. Derzeitige Impfstoffe und Antibiotika gegen diese Bakterien können die Verbreitung der Krankheit nicht ...

Phenotype‐Specific Semi‐Mechanistic Modelling of Florfenicol Time‐Kill Curves in G. Parasuis Compared to Other Respiratory Pathogens

Journal of Veterinary Pharmacology and Therapeutics, Volume 48, Issue 4, Page 318-339, July 2025.
ABSTRACT This study examines the pharmacodynamics (PD) of florfenicol (FFN) for treating porcine respiratory diseases by comparing its effects on Glaesserella parasuis, Actinobacillus pleuropneumoniae and Pasteurella multocida. In vitro time‐kill assays and semi‐mechanistic PD modeling were used to assess bacterial growth and killing rates at varying ...

Genetic relatedness and antimicrobial susceptibility of porcine respiratory tract pathogens Streptococcus suis, Bordetella bronchiseptica and Pasteurella multocida [PDF]

, 2019
Streptococcus suis is a Gram-positive bacterium and a commensal colonizing the porcine respiratory tract. However, some serotypes have a higher virulence and can cause pneumonia, meningitis, septicaemia, arthritis, endocarditis, polyserositis or abortion

The Arms Race Between Actinobacillus pleuropneumoniae and Its Genetic Environment: A Comprehensive Analysis of Its Defensome and Mobile Genetic Elements

Molecular Microbiology, Volume 124, Issue 1, Page 40-53, July 2025.
Using bioinformatic tools, we identified a diverse defensome in Actinobacillus pleuropneumoniae, featuring various defense mechanisms. Genomes show co‐occurring systems like CRISPR, Abi, and restriction‐modification (RM) systems, underscoring the complexity and dynamic nature of their defensome cargo.

Immunogenicity of Pasteurella multocida and Mannheimia haemolytica outer membrane vesicles

International Journal of Medical Microbiology, 2013
Pasteurella multocida is able to cause disease in humans and in a wide range of animal hosts, including fowl cholera in birds, atrophic rhinitis in pigs, and snuffles in rabbits. Together with Mannheimia haemolytica, P. multocida also represents a major bacterial causative agent of bovine respiratory disease (BRD), which is one of the most important ...

Periparturient mortality in merino ewes in Australia: Incidence, impact and the path to mitigation strategies

Australian Veterinary Journal, Volume 103, Issue 5, Page 287-297, May 2025.
Managing breeding ewe mortality is a priority for the Australian sheep industry. The periparturient period carries the highest risk of mortality, but the incidence and causes in Merino ewes are not well characterised. Here, we outline the reported incidence of annual and periparturient mortality for Australian Merino ewes, causes and risk factors for ...

Occurrence of haemolytic Mannheimia spp. in apparently healthy sheep in Norway

Acta Veterinaria Scandinavica, 2006
Background The occurrence of Mannheimia species in healthy sheep has only been investigated to a very limited extend since the genus and its five named species were established.

Immunological effects of feeding different sources of vitamin E and seaweed in a sheep herd during the winter season [PDF]

, 2012
In winter fed organic raised sheep inadequate plasma vitamin E levels is common and therefore supplementation is recommended. The objective of the present work was to test the supplementation of natural vitamin E and seaweed meal on the immune status ...

Dairy calf pneumonia: Effective treatment depends on early and accurate diagnosis [PDF]

, 2009
Dairy calf pneumonia is one of the most economically important diseases of calves. A delayed diagnosis could result endemic herd problem, prolonged use of antibiotics, high recurrence rate, pulmonary abscessation and ear infections. The key for effective

Association of Lung Consolidation Depth With Pathogens Isolated From Bronchoalveolar Lavage Fluid in Calves With Clinical Signs of Respiratory Disease

Journal of Veterinary Internal Medicine, Volume 39, Issue 3, May/June 2025.
ABSTRACT Background The depth of lung consolidation (≥ 1 and ≥ 3 cm) on thoracic ultrasonography (TUS) is increasingly used as a criterion for antimicrobial treatment. However, its association with bacterial infections remains unclear. Objectives To investigate the associations of clinical and ultrasonographic findings, particularly consolidation depth,
