AI Article Synopsis
- Rhodococcus equi is a type of bacteria that commonly causes pneumonia in foals, but this report discusses its first documented infection case in a bottlenose dolphin in Italy.
- The dolphin exhibited lung and colon damage during a post-mortem examination and tested positive for dolphin morbillivirus as well.
- Histological analysis confirmed the presence of lesions related to R. equi infection, including specific types of pneumonia and colitis, and whole genome sequencing validated the identification of the bacteria.
Article Abstract
Rhodococcus equi is a terrestrial bacterium and a common pathogen in foals (Equus caballus), in which causes pneumonia. This report describes for the first time the infection caused by R. equi in a common bottlenose dolphin (Tursiops truncatus) stranded in the Calabrian coast, Italy. The post mortem examination of the animal revealed lesions in lung and colon. The animal was also positive to dolphin morbillivirus. The histological study showed lesions attributable to R. equi infection, such as pyogranulomatous bacterial pneumonia and chronic granulomatous colitis. Whole genome sequencing of the isolated strain confirmed its identification as R. equi.

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

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.
