Differentially expressed genes in the femur cartilage transcriptome clarify the understanding of femoral head separation in chickens

Scientific Reports, 2021
Locomotor problems are among one of the main concerns in the current poultry industry, causing major economic losses and affecting animal welfare. The most common bone anomalies in the femur are dyschondroplasia, femoral head separation (FHS), and ...

Bacterial chondronecrosis with osteomyelitis in broilers

, 2022
The aim of this study was to perform a morphological analysis of bacterial chondronecrosis with osteomyelitis (BCO) in broilers. The study was performed at the Pathology center of the Department of Veterinary Pathobiology, LUHS VA, in 2021. In total, 53 broiler cadavers both with and without history of lameness were included in the study.

Development of an experimental model of bacterial chondronecrosis with osteomyelitis in broilers following exposure to Staphylococcus aureus by aerosol, and inoculation with chicken anaemia and infectious bursal disease viruses [PDF]

Avian Pathology, 1999
A series of experiments was designed in an attempt to reproduce bacterial chondronecrosis with osteomyelitis in broiler chickens using a natural route of infection. Birds in isolators were exposed to a suspension of Staphylococcus aureus by aerosol or exposed to S.

The anti-nuclease humoral immune response of broiler chickens exposed toStaphylococcus aureus, infectious bursal disease virus and chicken anaemia virus in an experimental model for bacterial chondronecrosis and osteomyelitis [PDF]

Avian Pathology, 2006
This study aimed to develop an enzyme-linked immunosorbent assay to detect antibody associated with Staphylococcus aureus that is produced during the chicken immune response to this organism. The protein nuclease was tested for suitability as an antigen to detect antibody in sera from broiler chickens that had been exposed to aerosolized S.

Prophylactic administration of a combined prebiotic and probiotic, or therapeutic administration of enrofloxacin, to reduce the incidence of bacterial chondronecrosis with osteomyelitis in broilers

Poultry Science, 2015
Bacteria entering the bloodstream via translocation from the gastrointestinal tract spread hematogenously and can trigger bacterial chondronecrosis with osteomyelitis (BCO) by infecting osteochondrotic microfractures in the epiphyseal-physeal cartilage of the proximal femora and tibiae.

Escherichia coli isolates from femoral bone marrow of broilers exhibit diverse pheno- and genotypic characteristics that do not correlate with macroscopic lesions of bacterial chondronecrosis with osteomyelitis

Avian Pathology, 2018
The pheno- and genotypic relatedness among Escherichia coli isolates from broilers with and without macroscopic lesions of the femoral head were investigated. In total, 219 isolates obtained from the bone marrow were characterized by serotyping, antimicrobial resistance (AMR) profiles, phylogenetic grouping, detection of virulence-associated genes ...

Commentary on “Understanding bacterial chondronecrosis with osteomyelitis (BCO) in poultry: Highlights from proteomic analyses and imaging techniques”

Journal of Neurobiology and Physiology
Bacterial chondronecrosis with osteomyelitis (BCO) is a leading cause of lameness in broiler chickens, which results in financial losses due to mortality and reduced growth. Due to the nature of the condition, it raises animal welfare and food safety concerns as well.

The Genetic Landscape of Antimicrobial Resistance Genes in Enterococcus cecorum Broiler Isolates

Antibiotics
Enterococcus cecorum is associated with bacterial chondronecrosis with osteomyelitis (BCO) in broilers. Prophylactic treatment with antimicrobials is common in the poultry industry, and, in the case of outbreaks, antimicrobial treatment is needed.

Assessing the impact of Spirulina platensis and organic trace minerals on the incidence of bacterial chondronecrosis with osteomyelitis lameness in broilers using an aerosol transmission model

Journal of Applied Poultry Research
SUMMARY: Spirulina platensis is an emerging poultry diet source due to its essential nutrition and bioactive ingredients. Spirulina microalgae confers beneficial effects on broiler's growth performance, immune response, and antioxidant activity. We investigated the effect of Spirulina platensis on BCO lameness, one of the most driving factors for ...
