Article
Full-text available
GtxA, a leukotoxic RTX-toxin, has been proposed a main virulence factor of Gallibacterium anatis. To evaluate the impact of GtxA during infection, we experimentally infected laying hens with a G. anatis wild-type (WT) strain and its isogenic gtxA deletion mutant (ΔgtxA), respectively, and monitored the birds during a 6 day period. Birds inoculated...
Article
Host-pathogen interactions of Pasteurella multocida isolates of different origin were studied in a mouse model, focusing on pathology, bacterial load and expression of the metalloproteinase MMP9 and its inhibitor TIMP1. Intranasal inoculation with one of three doses (106, 104, 102 CFU) of an isolate from porcine pneumonia or fowl cholera showed mar...
Article
Full-text available
Gallibacterium anatis is a major cause of reproductive tract infections in chickens. Here, we aimed to evaluate the efficacy of the recombinant protein GtxA-N at protecting hens, by addressing three objectives; (i) evaluating the antibody response following immunization (ii) scoring and comparing lesions, following challenge with G. anatis, in immu...
Article
Full-text available
The Gram-negative bacterium Gallibacterium anatis is a major cause of salpingitis and peritonitis in commercial egg-layers, leading to reduced egg production and increased mortality. Unfortunately, widespread multidrug resistance and antigenic diversity makes it difficult to control infections and novel prevention strategies are urgently needed. In...

Article
Full-text available
To evaluate Ovo-transferrin (OTF), a positive acute-phase protein in chickens, as a diagnostic biomarker of selected bacterial infections we checked the performance of a commercial Chicken-OTF-ELISA (ICL, Inc., Portland, OR, USA) by analytical and overlap performances using two groups of serum samples obtained from 26 Gallibacterium anatis-infected...
Article
The aim of this study was to investigate the pathogenic potential of Avibacterium endocarditidis. Forty broiler breeders were inoculated with one of three doses of the organism and killed at different time points. Bacteriology, pathology and fluorescence in-situ hybridization (FISH) were performed to evaluate bacterial growth and the development of...
Article
Infectious bronchopneumonia is a widespread disease in modern commercial pig production and Pasteurella multocida is frequently associated with the lesions. To evaluate porcine lung lesions associated with P. multocida, populations of inflammatory cells were examined by immunohistochemistry in necrotic lung lesions from nine pigs and exudative lung...
Article
Full-text available
Wild-type (WT) and small-colony-variant (SCV) strains of Streptococcus equi subsp. zooepidemicus have recently been isolated from a layer flock in Denmark experiencing high mortality. To investigate the disease-causing potential of SCV compared with WT, a 2-week long infection study was performed in 45-week-old brown layer chickens. Four groups of...
Article
Full-text available
The Gram-negative bacterium Gallibacterium anatis is a major cause of salpingitis and peritonitis in egg-laying chickens, leading to decreased egg production worldwide. Widespread multidrug resistance largely prevents treatment of this organism using traditional antimicrobial agents, while antigenic diversity hampers disease prevention by classical...

Table S2 Selected blood results in 4 dogs diagnosed with A. vasorum. PCV packed cell volume, PT prothrombin time, APTT activated partial thromboplastin time (individual references in brackets). Pool = internal reference value
Data
Table S1 A summary of signalment and clinical signs in 4 dogs with CNS haemorrhages associated with A. vasorum.
Article
Full-text available
Four dogs with acute neurological signs caused by haemorrhages in the central nervous system were diagnosed with Angiostrongylus vasorum infection as the underlying aetiology. Two dogs presented with brain lesions, one dog with spinal cord lesions and one with lesions in both the brain and spinal cord. Only one dog presented with concurrent signs o...
Article
With the aim to extend the present knowledge on possible systemic spreading of Pasteurella multocida in pigs with bronchopneumonia, the occurrence and associated lesions of P. multocida were described by comparing cultural detection, pathological evaluation and in situ hybridization of P. multocida in lungs, hearts and kidneys from cases of porcine...
Article
Pasteurella multocida is a major cause of porcine pneumonia, but the pathogenesis of the disease is poorly defined. The aim of this study was to further understand the host response to infection by use of a mouse model of P. multocida pneumonia. Twenty female mice were divided into four groups (n=5). Three groups were infected with one of three iso...
Article
Pasteurella multocida is a widespread respiratory pathogen in pigs associated with atrophic rhinitis and contributing to aggravation of the pulmonary lesions. The aims of the present study were to characterize isolates of P. multocida from porcine bronchopneumonia by pulsed-field gel electrophoresis (PFGE), PCR based capsular typing and multilocus...
Article
Respiratory infections are among the most important diseases of growing pigs. In order to elucidate the multifactorial aetiology of porcine respiratory disease complex (PRDC) in Denmark, lungs from 148 finishing pigs with cranioventral bronchopneumonia (case group) and 60 pigs without lung lesions (control group) were collected from abattoirs. The...
Article
Infection with porcine circovirus type 2 (PCV2) may be subclinical or lead to the development of porcine circovirus disease (PCVD), which includes the entities of post-weaning multisystemic wasting syndrome (PMWS) and the porcine respiratory disease complex (PRDC). PCV2 infection and PMWS occur in the early post-weaning period and are also recogniz...
Article
Full-text available
The pathogenesis of schistosomiasis japonica has been extensively studied, however only little attention has been paid to the presence and localization of mast cells in relation to Schistosoma japonicum induced lesions. The aim of the present pilot study was to assess the parasitological and pathological responses in S. japonicum infected pigs with...
