Analysis of the maturation of Rhodococcus equi-containing vacuoles in macrophages
Rhodococcus equi is a Gram-positive intracellular pathogen which can cause severe bronchopneumonia in foals. In recent years, the role of this bacterium as human pathogen has been noted, as R.equi infections in humans have increase in frequency. This increase is associated with the rise in …

Influence of Rhodococcus Equi on the Respiratory Burst of Resident Alveolar Macrophages From Horses
Rhodococcus equi is the etiologic agent of a devastating pneumonia of sporadic incidence in foals. Opsonized Rhodococcus equi are phagocytosed by equine alveolar macrophages but are ineffectively killed. The respiratory burst of equine neutrophils is obtunded by R. equi. If the bacteria similarly …

Purification and quantitative description of Rhodococcus equi IgG designed for aerosol nebulization to foals
… IgG from commercially available hyperimmune Rhodococcus equi plasma and to assess the delivery of IgG as an aerosol to the equine lung. IgG was purified from plasma, and the IgG concentration of both the plasma and the purified IgG was determined by ELISA. The purified IgG was aerosolized …

Purification and Activity of the DnaK Heat Shock Protein of the Emerging Human Pathogen Rhodococcus equi. Optimisation of methods of purifying DnaK from Rhodococcus equi, and the use of the purified protein in assays to demonstrate its activity in isolation and with other heat shock proteins
Rhodococcus equi is an important pathogen in foals between one to six months of age and is a major cause of death in in these animals. In addition, R. equi has recently emerged as a significant opportunistic pathogen in immunosuppressed humans, especially those infected with HIV. Despite the …

Structural Insights into Mycobacteriales Galactan Biosynthesis
… a previously undescribed GlfT2 paralog from Rhodococcus equi, which we term ReqGlfT3. We confirm its galactofuranosyl transferase activity and identify the production of β(1,3) and β(1,5) linkages. These findings offer new insights into GlfT2 and related polymerizing glycosyltransferases, …

Enzymatic degradation of egg yolk cholesterol
… in 2h. The cholesterol degrading activities of Rhodococcus equi, Rhodococcus erythropolis and two other unspeciated isolates of Rhodococcus were investigated in egg yolk and milk. These microorganisms, when grown on a cholesterol containing medium, resulted in halo formation around colonies of …

Evaluation of Different Methods for the Detection of Mycobacterium bovis in Lymph Node Tissue
… days compared to 15.2 days respectively). For Rhodococcus equi isolates 42%, 96.6% and 42% grew on BACTEC 460, MGIT 960 and solid culture systems respectively. For atypical mycobacteria isolates 89.5%, 43.4% and 10.5% grew on BACTEC 460, MGIT 960 and solid culture systems respectively. For …

Aerosol delivery of Rhodoccocus equi IgG to the lungs of ponies
… objective of this study was to determine if R. equi IgG purified from commmercially available hyperimmune R. equi plasma and delivered to the lungs of adult ponies would cause a local inflammatory response and if increases in total and R. equi specific IgG occurred post administration. IgG was …
