Rhodococcus equi, mainly known from veterinary medicine as a pathogen in domestic animals, can also cause infections in immunocompromised humans, especially in those with defects in cellular immunity. Alemtuzumab, an anti-CD52 monoclonal antibody, causes lymphocytopenia by eliminating CD52-positive cells. We report a patient in whom Rhodococcus equi infection developed after alemtuzumab therapy.

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.

is a rare human opportunistic pathogen that has been increasingly reported in recent decades. It mainly affects immunosuppressed patients, and in particular human immunodeficiency virus (HIV)-infected patients, where it typically presents as cavitary pneumonia. Early treatment with combined and effective antimicrobials and antiretroviral therapy after prompt diagnosis is essential to ensure an optimal outcome.
