AI Article Synopsis
- A 4-month-old Missouri Fox Trotter colt was examined due to a 5-week history of head tilt following treatment for a suspected lung infection.
- A CT scan revealed significant bone loss and a soft tissue mass compressing critical areas of the colt's brain.
- Surgery was performed to remove damaged bone and the mass, leading to substantial recovery of neurologic function in just three days, with bacterial culture confirming the presence of R. equi.
Article Abstract
Case Description: A 4-month-old Missouri Fox Trotter colt was examined for a 5-week history of head tilt after treatment for suspected pulmonary Rhodococcus equi infection.
Clinical Findings: Computed tomography revealed osteolysis of the occipital, temporal, and caudal portion of the parietal bones of the left side of the cranium. A soft tissue mass compressing the occipital region of the cerebral cortex and cerebellum was associated with the osteolytic bone.
Treatment And Outcome: A rostrotentorial-suboccipital craniectomy approach was performed to remove fragmented occipital bone, debulk the intracranial mass, and obtain tissue samples for histologic examination and bacterial culture. All neurologic deficits improved substantially within 3 days after surgery. Bacterial culture of the resected soft tissue and bone fragments yielded R equi.
Clinical Relevance: Intracranial surgery in veterinary medicine has been limited to dogs and cats; however, in select cases, extrapolation of surgical techniques used in humans and small animals can assist with intracranial procedures in horses.

Clade-1 Vap virulence proteins of Rhodococcus equi are associated with the cell surface and support intracellular growth in macrophages.
PLoS One

UCD School of Biomolecular and Biomedical Science and UCD Conway Institute, University College Dublin, Dublin, Ireland.
The multi-host pathogen Rhodococcus equi is a parasite of macrophages preventing maturation of the phagolysosome, thus creating a hospitable environment supporting intracellular growth. Virulent R. equi isolated from foals, pigs and cattle harbor a host-specific virulence plasmid, pVAPA, pVAPB and pVAPN respectively, which encode a family of 17 Vap proteins belonging to seven monophyletic clades.

Rhodococcus equi (R. equi) is a primary cause of pyogranulomatous pneumonia of foals between three weeks and five months of age. Early diagnosis of rhodococcal pneumonia has always been considered a preferable approach as it can lead to more successful treatment and better outcomes.

Introduction: Platelet lysate (PL) demonstrates antimicrobial and anti-inflammatory properties offering potential for treatment of bacterial pneumonia in horses. It remains unknown whether nebulization is suitable for PL administration in horses. This pilot study characterized particle size and flow rate of pooled equine PL (single preparation) nebulized using an equine-specific nebulizer (Flexivent).

Article Synopsis
- The study aimed to analyze how the occurrence of different infectious agents in foals with diarrhea varies by age, using fecal samples sent for testing over two years.
- Results showed that 42.9% of samples tested positive for pathogens, with Rotavirus A being the most common, particularly among foals younger than one month, where it was frequently found alongside other toxins.
- The findings affirm age dependency in pathogen occurrence but suggest that infections can happen outside the expected age range; therefore, a comprehensive diagnostic approach for diarrheic foals should be used to identify all possible pathogens and prevent further spread.

Introduction: causes life-threatening respiratory disease in foals. The standard treatment typically involves a combination of rifampicin and a macrolide antibiotic. Although previous studies have demonstrated the activity of these antibiotics against , the tested concentrations often do not reflect those achievable in foals.
